The study aimed to compare the sedative effectiveness of thiopental versus midazolam in reduction of shoulder dislocation.METHODS: A randomized double-blind controlled trail was performed in 80 patients with shoulder dislocation recruited from the emergency department. Ten patients were excluded and 70 patients were enrolled in the study. Case group received intravenous thiopental 2 mg/kg+2 μg/kg fentanyl while control group received intravenous midazolam 0.1 mg/kg+2 μg/kg fentanyl. Number of times, patients and physician's satisfaction, difficulty of procedure, degree of muscle relaxation, time of sedation and complete recovery, number of patients with apnea episode, O2 saturation, patient's pain score and adverse events were all recorded.RESULTS: Muscular tone had significant difference between the two groups(P-value=0.014) and thiopental was more muscle relaxant than midazolam. Replacement of shoulder dislocation in thiopental group was easier than midazolam group(P-value=0.043). There was no need to use multiple methods of reduction in either group. Before drug infusion the mean±SD VAS scores were 8.37±2.21 in the midazolam group(A) and 8.94±1.78 in the thiopental group(B); mean difference 0.57, 95% CI= –0.38 to 1.52. After completion of the procedure, the mean±SD VAS scores in group(A) and(B) were 3.20±1.30 vs. 3.65±1.30; mean difference –0.45, 95% CI= –1.07 to 0.16.CONCLUSION: Thiopental might be more effective and relaxant than midazolam for reduction of shoulder dislocation.展开更多

When it does occur, blocks to reduction can include bone, labrum, rotator cuff musculature or tendon. Patients older than 40 at the time of initial dislocation are at increased risk of sustaining a concomitant rotator cuff tear. We present a case of an irreducible anterior shoulder dislocation due to interposition of both subscapularis tendon and a posteriorly dislocated long head of biceps. Both Computed Tomography (CT) and magnetic resonance imaging (MRI), along with intraoperative findings are discussed. Conclusion: We would advocate maintaining a low threshold for MR imaging post shoulder dislocation in the older population, when there is radiological or clinical concern regarding the integrity of the rotator cuff, and also to evaluate whether a concentric reduction of the shoulder joint has been achieved.展开更多

The shoulder anatomy promotes high mobility and favors relative sacrifice of articular stability, making it susceptible and more prone to events of instability and dislocation. This review aimed at identifying main complications of surgical treatment of anterior shoulder dislocation. Methodology: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Studies which were eligible for this systematic review included: English or Spanish language, studies published from 2000, which mentioned surgical complications of anterior shoulder dislocation in their results, both in open and arthroscopic surgery. Included studies which were required to have at least 1 complication following surgical repair. Only studies from original data were included. Results: We found 228 potentially eligible studies for the survey. Through the inclusion and exclusion criteria and after consensus among reviewers, we chose 9 studies to compose the systematic review. Conclusion: Important information emerges: recurring instability, recurring dislocation, external rotation limitation and arthritis are main surgical complications of anterior shoulder dislocation.展开更多

We report the case of a 69-year-old farmer under coumarin anticoagulant therapy who sustained acute first time anterior dislocation of his dominant right shoulder. By using the Hippocrates method with the patient under general anaesthesia, the brachial vein was injured and an increasing hematoma subsequently caused brachial plexus paresis by pressure. After surgery for decompression and vascular suturing, symptoms declined rapidly, but brachial plexus paresis still was not fully reversible after 3 mo of follow-up. The hazardousness of using the Hippocrates method can be explained by traction on the outstretched arm with force of the operator's body weight, direct trauma to the axillary region by the physician's heel, and the topographic relations of neurovascular structures and the dislocated humeral head. As there is a variety of alternative reduction techniques which have been evalu-ated scientifically and proofed to be safe, we strongly caution against the use of the Hippocrates method as a first line technique for reducing anterior shoulder dislocations, especially in elder patients with fragile vessels or under anticoagulant therapy, and recommend the scapular manipulation technique or the Milch technique, for example, as a first choice.展开更多

Most cases resulted in severe complications like avascular necrosis of the humeral head or septic arthritis with poor functional results. The "mandatory" treatment of choice is surgery, with accurate debridement and reconstruction of the damaged soft tissues. However, the results in these cases do not approach those seen in classical dislocations.CASE SUMMARY This case report is the first description of an anterior open glenohumeral dislocation without associated fractures, but with complete avulsion of the soft tissue envelope of the proximal humerus. Surgical treatment consisted of copious lavage with saline solution, meticulous debridement of the nonviable soft tissues,reduction of the dislocated humeral head and reconstruction of the soft tissue envelope of the humeral head. The selected surgical approach was an inferior extension of the wound at the level of the delto-pectoral groove, as the best choice to be able to perform an adequate debridement and capsulo-tendinous reinsertion. At 6 mo there were no clinical signs of instability of the glenohumeral joint, the functionality of the joint was restricted to 90o of anterior elevation,internal rotation to L2, with severe limitation of abduction(60o) and external rotation(0o) but without residual pain, with an Oxford shoulder Score of 28.CONCLUSION Thorough reconstruction of the soft tissues surrounding the shoulder joint and an early rehabilitation program are key points to a good functional result.展开更多

It account for 2% - 4% of all shoulder dislocations. It is commonly associated with osseous defects in humeral head articular surface known as reverse Hill-Sachs lesion. Numerous surgical procedures invented to repair this defect with variable outcomes but evidence based management strategies are lacking. Among these procedures are: transfer of lesser tuberosity or subscapularis tendon, rotational osteotomy of humerus, osteochondral grafts. Salvage procedure as hemiarthroplasty or total shoulder arthroplasty used in huge non-constructable defect or very old neglected dislocation. In our case series, we treated 9 cases (2 females) of locked posterior shoulder dislocation with antero-medial humeral head defects ranging between 30% - 50% of head size. Open reduction of dislocation followed by transfer of the lesser tuberosity together with subscapularis tendon for reconstruction of the humeral head defect. The transfer was fixed with Ethibond suture size 5-0 (Ethicon, Inc. Somerville, New Jersy). The mean follow-up period was 14.5 months (range, 12 - 25 months). Seven cases had no pain or restriction of activities of daily living. No patient had symptoms of instability of the shoulder. According to UCLA Shoulder rating scale, there were 3 cases rated excellent, 4 cases rated good, one case rated fair and one case rated poor. It is concluded that reconstruction of the humeral head defect provides good pain relief, stability and function for patients with a locked posterior dislocation where the defect involves between 30% - 50% of the articular surface circumference. Our technique is simple, cheap and there is no need for second operation for hardware removal.展开更多

The objective was to describe the epidemiological, therapeutic and evolutionary aspects of traumatic shoulder dislocations in Bouaké. Methods: This retrospective and descriptive study was conducted between January 2017 and December 2019. It concerned patients over 15 years of age with a recent traumatic shoulder dislocation treated and followed in the department. The variables studied were epidemiological, therapeutic and evolutionary. The severity of the trauma was assessed according to the Injury Severity Score (ISS). Functional outcome was assessed according to the Constant score. Results: There were 49 patients (49 dislocations) out of 22,569 patients. The prevalence was 0.2%. The mean age was 32 years (17 - 62). There were 38 men (77.5%). The sex ratio was 3.4. Students predominated (n = 10;20.4%). The etiology was dominated by road traffic accidents (n = 19;38.8%). Anterior dislocation was the most common (n = 45;92%). The ISS score was minor (n = 46;93.8%). The mean time to reduction was 7 hours (4 - 16). Orthopaedic reduction using the Kocher technique predominated (n = 44;89.8%). The mean duration of external rotation immobilisation of the shoulder was 23 days (16 - 45). Recurrence occurred in 8 patients (21.6%). The functional outcome at a mean Constant follow-up of 15 months (8 - 20) was satisfactory (n = 44;89.8%). Conclusion: Traumatic dislocation of the shoulder represented 0.2%. Treatment was mainly orthopaedic. Recurrence was rare.展开更多

Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.展开更多

They are often overlooked during the initial examination and delayed diagnosis adversely affects healing process. Apart from many open treatment options, there are reports of single attempts to treat such cases arthroscopically. Purpose: We present an original case of a posterior locked dislocation of the shoulder joint with a fracture of the lesser tuberosity followed by reverse Hill-Sachs fracture, treated in a novel fashion all-arthroscopically with the use of allogenic bone graft. Method: According to Constant Shoulder Score that tries to assess functional and subjective performance of the shoulder joint before the operation and after 12 months, we achieved a leap from 11 to 84. Results: The patient restored almost full range of motion and painless movement in activities of daily life as well as during sports. Conclusion: The use of an arthroscope reduces the invasiveness of the procedure, improves visualization of the joint and allows augmentation of the bone loss without performing an open approach. We believe that this is a promising method of treatment for selected cases of locked posterior shoulder dislocation.展开更多

They are even rarer when combined with a bilateral fracture of major tubercles. We report the case of a 28-year-old patient admitted to trauma emergencies after trauma by falling from the top of a stool. Clinical and radiographic findings revealed bilateral anterior shoulder dislocation associated with bilateral fracture of major tubercles. The patient was treated orthopedically by a reduction of dislocations under General Anesthesia, immobilization of the shoulders for 6 weeks followed by reeducation. The functional result after 12 months was satisfactory with a UCLA score of 30 points.展开更多

METHODS: We conducted a systematic review according to the PRISMA guidelines. A literature search was performed in PubM ed, EMBASE and Google Scholar using the following search terms: "rugby" and "shoulder" in combination with "instability" or "dislocation". All articles published from inception of the included data sources to January 1st 2014 that evaluated surgical treatment of elite rugby players with anterior shoulder instability were examined. RESULTS: Only five studies were found that met the eligibility criteria. A total of 379 shoulders in 376 elite rugby union and league players were included. All the studies were retrospective cohort or case series studies. The mean Coleman Methodological Score for the 5 studies was 47.4(poor). Owing to heterogeneity amongst the studies, quantitative synthesis was not possible, however a detailed qualitative synthesis is reported. The overall recurrence rate of instability after surgery was 8.7%, and the mean return to competitive play, where reported, was 13 mo.CONCLUSION: Arthroscopic stabilization has been performed successfully in acute anterior instability and there is a preference for open Latarjet-type procedures when instability is associated with osseous defects.展开更多

Because of increasing pa...The purpose of this review article is to discuss the clinical spectrum of recurrent traumatic anterior shoulder instability with the current concepts and controversies at the scientific level. Because of increasing participation of people from any age group of the population in sports activities, health care professionals dealing with the care of trauma patients must have a thorough understanding of the anatomy, patho-physiology, risk factors, and management of anterior shoulder instability. The risk factors for recurrent shoulder dislocation are young age, participation in high demand contact sports activities, presence of Hill-Sachs or osseous Bankart lesion, previous history of ipsilateral traumatic dislocation, ipsilateral rotator cuff or deltoid muscle insufficiency, and underlying ligamentous laxity. Achieving the best result for any particular patient depends onthe procedure that allows observation of the joint surfaces, provides the anatomical repair, maintains range of motion, and also can be applied with low rates of complications and recurrence. Although various surgical techniques have been described, a consensus does not exist and thus, orthopedic surgeons should follow and try to improve the current evidence-based treatment modalities for the patients.展开更多

METHODS: A retrospective review was conducted at a single facility. Cases were identified using a com-puterized database and all clinic notes and operative reports were reviewed. All patients with epilepsy and recurrent shoulder instability were included for study. Between July 2003 and August 2011 five shoulders in five consecutive patients with epilepsy underwent fixed-fulcrum fully constrained reverse shoulder arthroplasty for recurrent anterior shoulder instability. The mean duration of epilepsy in the cohort was 21 years(range, 5-51) and all patients suffered from grand mal seizures. RESULTS: Mean age at the time of surgery was 47 years(range, 32-64). The cohort consisted of four males and one female. Mean follow-up was 4.7 years(range, 4.3-5 years). There were no further episodes of instability, and no further stabilisation or revision procedures were performed. The mean Oxford shoulder instability score improved from 8 preoperatively(range, 5-15) to 30 postoperatively(range, 16-37)(P = 0.015) and the mean subjective shoulder value improved from 20(range, 0-50) preoperatively to 60(range, 50-70) postoperatively(P = 0.016). Mean active forward elevation improved from 71° preoperatively(range,45°-130°) to 100° postoperatively(range, 80°-90°) and mean active external rotation improved from 15° preoperatively(range, 0°-30°) to 40°(20°-70°) postoperatively. No cases of scapular notching or loosening were noted. CONCLUSION: Fixed-fulcrum fully constrained reverse shoulder arthroplasty should be considered for the treatment of recurrent shoulder instability in patients with epilepsy.展开更多
文摘BACKGROUND Posterior shoulder dislocation is a rare injury.It accounts for only 1%-4%of all shoulder dislocation cases.However,this injury is often underdiagnosed.Massive rotator cuff tears associated with posterior shoulder dislocation are exceptionally rare.Early diagnosis and surgical management are crucial for restoring shoulder function and preventing long-term disability.CASE SUMMARY A 60-year-old male with no previous shoulder injuries presented to our hospital with severe right shoulder pain and immobility after a motorcycle accident.He reported that he braced his fall with his right hand.Initial imaging examination revealed posterior shoulder dislocation with minimal glenoid bone loss.Six days after the injury,the patient exhibited pseudoparalysis and active forward flexion limited to 10°.Two weeks after the injury,magnetic resonance imaging revealed complete tears of the supraspinatus,infraspinatus,and subscapularis muscles as well as dislocation of the long head of the biceps tendon.Arthroscopic rotator cuff repair was performed 6 weeks after injury.The tendon quality was acceptable with minimal fatty infiltration.At the 12-month surgical follow-up,the patient had recovered full strength and complete range of motion.CONCLUSION Early diagnosis and tailored repair of massive rotator cuff tears after dislocation are crucial for restoring shoulder function in older patients.

文摘An Irreducible dislocation of the shoulder is an uncommon event. When it does occur, blocks to reduction can include bone, labrum, rotator cuff musculature or tendon. Patients older than 40 at the time of initial dislocation are at increased risk of sustaining a concomitant rotator cuff tear.

文摘Introduction: shoulder joint has the greatest range of motion in the human body. The shoulder anatomy promotes high mobility and favors relative sacrifice of articular stability, making it susceptible and more prone to events of instability and dislocation.

文摘BACKGROUND Open dislocation of the glenohumeral joint is a very rare complication with only six cases described in the literature. Most cases resulted in severe complications like avascular necrosis of the humeral head or septic arthritis with poor functional results. The "mandatory" treatment of choice is surgery, with accurate debridement and reconstruction of the damaged soft tissues. However, the results in these cases do not approach those seen in classical dislocations.CASE SUMMARY This case report is the first description of an anterior open glenohumeral dislocation without associated fractures, but with complete avulsion of the soft tissue envelope of the proximal humerus. Surgical treatment consisted of copious lavage with saline solution, meticulous debridement of the nonviable soft tissues,reduction of the dislocated humeral head and reconstruction of the soft tissue envelope of the humeral head. The selected surgical approach was an inferior extension of the wound at the level of the delto-pectoral groove, as the best choice to be able to perform an adequate debridement and capsulo-tendinous reinsertion. At 6 mo there were no clinical signs of instability of the glenohumeral joint, the functionality of the joint was restricted to 90o of anterior elevation,internal rotation to L2, with severe limitation of abduction(60o) and external rotation(0o) but without residual pain, with an Oxford shoulder Score of 28.CONCLUSION Thorough reconstruction of the soft tissues surrounding the shoulder joint and an early rehabilitation program are key points to a good functional result.
文摘Objective To investigate the clinical implications of early rehabilitative treatment for uncomplete dislocation of shoulder after stroke.Method 420 patients received the anti－ spasticity treatment of upper limb,protecting techniques and sling were also used for all patients.Result The recovery of uncomplete dislocation of shoulder after stroke was satisfying.Conclusion Early rehabilitative treatment was beneficial for the improvement of uncomplete dislocation of shoulder after stroke.
文摘BACKGROUND Glenohumeral dislocation is a common injury that may predispose patients to chronic pain and instability.However,there is a paucity of current data available regarding the epidemiological trends of this injury.AIM To provide an updated,comparative assessment of the epidemiology of shoulder dislocations presenting to emergency departments in the United States.We also sought to analyze patient demographic risk factors and consumer products associated with dislocation events.METHODS Data were obtained from the national electronic injury surveillance system database for glenohumeral dislocations between 2012 and 2021.Incidence,age,sex,and injury characteristics were analyzed using weighted population statistics as well as incidence rates and 95%confidence intervals(CI).RESULTS In total,an estimated 773039 shoulder dislocations(CI:640598-905481)presented to emergency rooms across the United States during the study period.The annual incidence rate was 23.96 per 100000 persons and the average patient age at the time of injury was 37.1 years.Significantly more male patients sustained dislocations than female patients(537189,69.5%,vs 235834,30.5%,P<0.001).With regard to associated consumer products,sports and recreation equipment were involved in the highest proportion of incidents(44.31%),followed by home structures and construction materials(21.22%),and home furnishings,fixtures,and accessories(21.21%).Regarding product sub-groups,stairs,ramps,landings,floors was cited in the greatest number of cases(131745).CONCLUSION The national annual incidence rate of glenohumeral dislocations throughout the study period was approximately 23.92 per 100000 persons.Male adolescents sustained the highest proportion of dislocations,with a peak incidence in age group 15-20 years,predominantly secondary to participation in sporting and recreational activities.Conversely,women experienced a relatively consistent incidence of dislocation throughout their lifespan.After age 63,the incidence rate of dislocations in females was found to surpass that observed in males.
文摘BACKGROUND:Traumatic bilateral hip dislocation is a rare condition.Anterior shoulder dislocation combined with this condition is even a rare occurrence.A 57-year-old man had bilateral asymmetric hip dislocation with a posterior wall fracture of the left acetabulum associated with right shoulder anterior dislocation caused by falling down from a cherry tree.Traumatic hip dislocation and anterior shoulder dislocation represent a true orthopedic emergency.METHODS:Closed reduction was performed immediately for three of the dislocated joints.Posterior wall fracture of the left acetabulum was treated with open reduction and internal fixation by screws.Because of the severity of associated complications like aseptic necrosis or posttraumatic osteoarthritis,efforts were made to ensure prompt diagnosis,therapy and prognosis.RESULTS:The patient was successfully treated by open reduction and internal fixation of the left acetabulum,and discharged from the hospital.CONCLUSION:Traumatic asymmetric hip dislocation and anterior shoulder dislocation are an orthopedic emergency and early diagnosis with immediate reduction of the dislocation is the key determinants of excellent result of treatment.
文摘Locked posterior dislocation shoulder is uncommon and frequently missed injury. It account for 2% - 4% of all shoulder dislocations. It is commonly associated with osseous defects in humeral head articular surface known as reverse Hill-Sachs lesion. Numerous surgical procedures invented to repair this defect with variable outcomes but evidence based management strategies are lacking. Among these procedures are: transfer of lesser tuberosity or subscapularis tendon, rotational osteotomy of humerus, osteochondral grafts. Salvage procedure as hemiarthroplasty or total shoulder arthroplasty used in huge non-constructable defect or very old neglected dislocation. In our case series, we treated 9 cases (2 females) of locked posterior shoulder dislocation with antero-medial humeral head defects ranging between 30% - 50% of head size. Open reduction of dislocation followed by transfer of the lesser tuberosity together with subscapularis tendon for reconstruction of the humeral head defect. The transfer was fixed with Ethibond suture size 5-0 (Ethicon, Inc. Somerville, New Jersy). The mean follow-up period was 14.5 months (range, 12 - 25 months). Seven cases had no pain or restriction of activities of daily living. No patient had symptoms of instability of the shoulder. According to UCLA Shoulder rating scale, there were 3 cases rated excellent, 4 cases rated good, one case rated fair and one case rated poor. It is concluded that reconstruction of the humeral head defect provides good pain relief, stability and function for patients with a locked posterior dislocation where the defect involves between 30% - 50% of the articular surface circumference. Our technique is simple, cheap and there is no need for second operation for hardware removal.
文摘Introduction: Shoulder dislocations represent about 50% of all joint dislocations. The objective was to describe the epidemiological, therapeutic and evolutionary aspects of traumatic shoulder dislocations in Bouaké. Methods: This retrospective and descriptive study was conducted between January 2017 and December 2019. It concerned patients over 15 years of age with a recent traumatic shoulder dislocation treated and followed in the department. The variables studied were epidemiological, therapeutic and evolutionary. The severity of the trauma was assessed according to the Injury Severity Score (ISS). Functional outcome was assessed according to the Constant score. Results: There were 49 patients (49 dislocations) out of 22,569 patients. The prevalence was 0.2%. The mean age was 32 years (17 - 62). There were 38 men (77.5%). The sex ratio was 3.4. Students predominated (n = 10;20.4%). The etiology was dominated by road traffic accidents (n = 19;38.8%). Anterior dislocation was the most common (n = 45;92%). The ISS score was minor (n = 46;93.8%). The mean time to reduction was 7 hours (4 - 16). Orthopaedic reduction using the Kocher technique predominated (n = 44;89.8%). The mean duration of external rotation immobilisation of the shoulder was 23 days (16 - 45). Recurrence occurred in 8 patients (21.6%). The functional outcome at a mean Constant follow-up of 15 months (8 - 20) was satisfactory (n = 44;89.8%). Conclusion: Traumatic dislocation of the shoulder represented 0.2%. Treatment was mainly orthopaedic. Recurrence was rare.
文摘Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.
文摘Background: Locked posterior shoulder dislocations are uncommon and possess many difficulties in diagnosis. They are often overlooked during the initial examination and delayed diagnosis adversely affects healing process. Apart from many open treatment options, there are reports of single attempts to treat such cases arthroscopically. Purpose: We present an original case of a posterior locked dislocation of the shoulder joint with a fracture of the lesser tuberosity followed by reverse Hill-Sachs fracture, treated in a novel fashion all-arthroscopically with the use of allogenic bone graft. Method: According to Constant Shoulder Score that tries to assess functional and subjective performance of the shoulder joint before the operation and after 12 months, we achieved a leap from 11 to 84. Results: The patient restored almost full range of motion and painless movement in activities of daily life as well as during sports. Conclusion: The use of an arthroscope reduces the invasiveness of the procedure, improves visualization of the joint and allows augmentation of the bone loss without performing an open approach. We believe that this is a promising method of treatment for selected cases of locked posterior shoulder dislocation.
文摘Bilateral anterior dislocations of the shoulder are rare lesions. They are even rarer when combined with a bilateral fracture of major tubercles. We report the case of a 28-year-old patient admitted to trauma emergencies after trauma by falling from the top of a stool. Clinical and radiographic findings revealed bilateral anterior shoulder dislocation associated with bilateral fracture of major tubercles. The patient was treated orthopedically by a reduction of dislocations under General Anesthesia, immobilization of the shoulders for 6 weeks followed by reeducation. The functional result after 12 months was satisfactory with a UCLA score of 30 points.
文摘AIM: To systematically evaluate the evidence-based literature on surgical treatment interventions for elite rugby players with anterior shoulder instability. METHODS: We conducted a systematic review according to the PRISMA guidelines. A literature search was performed in PubM ed, EMBASE and Google Scholar using the following search terms: "rugby" and "shoulder" in combination with "instability" or "dislocation". All articles published from inception of the included data sources to January 1st 2014 that evaluated surgical treatment of elite rugby players with anterior shoulder instability were examined. RESULTS: Only five studies were found that met the eligibility criteria. A total of 379 shoulders in 376 elite rugby union and league players were included. All the studies were retrospective cohort or case series studies. The mean Coleman Methodological Score for the 5 studies was 47.4(poor). Owing to heterogeneity amongst the studies, quantitative synthesis was not possible, however a detailed qualitative synthesis is reported. The overall recurrence rate of instability after surgery was 8.7%, and the mean return to competitive play, where reported, was 13 mo.CONCLUSION: Arthroscopic stabilization has been performed successfully in acute anterior instability and there is a preference for open Latarjet-type procedures when instability is associated with osseous defects.
文摘BACKGROUND Clavicle fractures are among the most common fractures seen in the emergency department.While acromioclavicular(AC)joint injuries are much less common.However,ipsilateral combinations of these injuries are quite rare with only a few cases reported in the literature.CASE SUMMARY A 29-year-old man who sustained a combination of ipsilateral AC joint dislocation and midshaft clavicle fracture.He underwent open reduction and plate fixation of the clavicle fracture,as well as semi-rigid surgical implants used to restore both the AC ligaments and the coracoclavicular joint.one year follow-up revealed that the patient had a complete range of motion and excellent shoulder scores.This case presents a rare presentation of such combination of injuries,contributing valuable insights to the literature on such rare injuries.CONCLUSION Combined midshaft clavicle fractures and AC joint dislocations are considered quite rare.Timely diagnosis of such injuries leads to great functional outcomes.AC joint dislocation should be suspected with midshaft clavicle fractures and should be investigated radiologically and clinically in an appropriate manner.Still,there is no consensus on the optimal management of such injuries.
文摘BACKGROUND Dislocation of the long head of biceps tendon(LHBT)usually involves rotator cuff injury,and isolated dislocation with an intact rotator cuff is rare.Some cases of isolated dislocation have been reported.However,to the best of our knowledge,there has been no report of bilateral dislocation of the LHBT without rotator cuff pathology.CASE SUMMARY A 23-year-old male presented to our outpatient clinic with left side dominant pain in both shoulders.The patient had no history of trauma or overuse.The patient underwent intra-articular injection and physical therapy,but his symptoms aggravated.Based on preoperative imaging,the diagnosis was bilateral dislocation of the LHBT.Dysplasia of the bicipital groove was detected in both shoulders.Active dislocation of the biceps tendon over an intact subscapularis tendon was identified by diagnostic arthroscopy.Staged biceps tenodesis was performed and continuous passive motion therapy was administered immediately after surgery.The patient’s pain was resolved,and full functional recovery was achieved,and he was satisfied with the condition of his shoulders.CONCLUSION This study describes a rare case of bilateral dislocations of the LHBT without rotator cuff injury due to dysplasia of the bicipital groove.
文摘The purpose of this review article is to discuss the clinical spectrum of recurrent traumatic anterior shoulder instability with the current concepts and controversies at the scientific level. Because of increasing participation of people from any age group of the population in sports activities, health care professionals dealing with the care of trauma patients must have a thorough understanding of the anatomy, patho-physiology, risk factors, and management of anterior shoulder instability. The risk factors for recurrent shoulder dislocation are young age, participation in high demand contact sports activities, presence of Hill-Sachs or osseous Bankart lesion, previous history of ipsilateral traumatic dislocation, ipsilateral rotator cuff or deltoid muscle insufficiency, and underlying ligamentous laxity. Achieving the best result for any particular patient depends onthe procedure that allows observation of the joint surfaces, provides the anatomical repair, maintains range of motion, and also can be applied with low rates of complications and recurrence. Although various surgical techniques have been described, a consensus does not exist and thus, orthopedic surgeons should follow and try to improve the current evidence-based treatment modalities for the patients.
文摘AIM: To report the results of fixed-fulcrum fully constrained reverse shoulder arthroplasty for the treatment of recurrent shoulder instability in patients with epilepsy. METHODS: A retrospective review was conducted at a single facility. Cases were identified using a com-puterized database and all clinic notes and operative reports were reviewed. All patients with epilepsy and recurrent shoulder instability were included for study. Between July 2003 and August 2011 five shoulders in five consecutive patients with epilepsy underwent fixed-fulcrum fully constrained reverse shoulder arthroplasty for recurrent anterior shoulder instability. The mean duration of epilepsy in the cohort was 21 years(range, 5-51) and all patients suffered from grand mal seizures. RESULTS: Mean age at the time of surgery was 47 years(range, 32-64). The cohort consisted of four males and one female. Mean follow-up was 4.7 years(range, 4.3-5 years). There were no further episodes of instability, and no further stabilisation or revision procedures were performed. The mean Oxford shoulder instability score improved from 8 preoperatively(range, 5-15) to 30 postoperatively(range, 16-37)(P = 0.015) and the mean subjective shoulder value improved from 20(range, 0-50) preoperatively to 60(range, 50-70) postoperatively(P = 0.016). Mean active forward elevation improved from 71° preoperatively(range,45°-130°) to 100° postoperatively(range, 80°-90°) and mean active external rotation improved from 15° preoperatively(range, 0°-30°) to 40°(20°-70°) postoperatively. No cases of scapular notching or loosening were noted. CONCLUSION: Fixed-fulcrum fully constrained reverse shoulder arthroplasty should be considered for the treatment of recurrent shoulder instability in patients with epilepsy.
