Methods: forty patients with thoracolumbar burst fractures admitted to our hospital from April 2018 to December 2020 were randomly divided into study group and control group with 20 cases in each group. The control group was treated with short-segment minimally invasive internal fixation combined with injured vertebral bone graft, and the study group was treated with posterior approach anterior spinal canal decompression combined with injured vertebral internal fixation. The perioperative conditions, postoperative vertebral height, endplate angle and bony fusion of the two groups were evaluated and compared. Results: the operation time of the study group was shorter than that of the control group, and the amount of hemorrhage was less than that of the control group. At the stage of 12 months after operation, the height of the vertebral body in the study group was higher than that of the control group, and the endplate angle was smaller than that of the control group. The difference was statistically significant (P < 0.05). There was no significant difference in the osseous fusion between the two groups (P > 0.05). Conclusion: posterior anterolateral spinal canal decompression combined with internal fixation for thoracolumbar burst fractures has less intraoperative bleeding, which can reduce the risk of vertebral height loss and vertebral deformity on the basis of ensuring the effect of bony fusion.展开更多

The outcome of severely displaced supracondylar fracture of the humerus in children subjected to wide controversies in term of safety, functional and cosmetic outcome. Closed reduction and percutaneous pinning is now considered as the gold standard rule, but open reduction still applicable in certain cases where intraoperative imaging is not available, in comminuted lateral column fractures and uneducable fractures. Aim of the Study: To compare the outcome (functional and cosmetic) of anterior (Henry) approach with the posterior (Campbell) approach used in two groups of patients’ sustained displaced supracondylar fractures. Patients and Methods: This prospective study was performed on 48 pediatric patients who were been admitted to the Emergency Hospital in Sulaimani province sustained displaced supracondylar humeral fractures and treated during the period from the first of October 2009 to the thirty-one of January 2011. The study included 28 boys, 20 girls;their mean age was 7.5 years;their ages range 2 - 13 years. We used the modified Gartland classification to assess the fractures displacement and only Gartland type II B and III were included and managed operatively by open reduction and internal fixation with 2 crossed K-wires. Follow up continued for 6 months and the results finally assessed using Flynn’s criteria. Results: According to the criteria of Flynn et al., 20 patients (83.3%) treated by the anterior approach had excellent functional results while 4 patients (16.7%) had good functional results. While those treated by the posterior approach, 16 patients (66.6%) had excellent functional results, 6 patients (25%) had good results and 2 (8.3%) patients had fair outcome. Cosmetic results were excellent in 22 patients in the anterior approach group and 20 patients in the posterior approach group. Conclusion: Posterior Campbell approach is simpler than anterior Henry approach, but it creates additional soft tissue damage that can affect the circulatory status and hence possible osteonecrosis of the trochlea and a higher percentage of limitation in joint mobility. While the anterior approach is technically more demanding, but it gives better functional results.展开更多

However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children. Methods Ten pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months. Results The patients were followed-up for an average of 26 months （range, 15-32 months）. There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° （range, 30-52°） before the operation to 18° （range, 12-26°） post-operation. Neurological function was improved in all patients. Conclusions Combined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.展开更多

Methods: The data of 8 patients with lower cervical spine C6 or C7 injury （6 patients with fracture and dislocation in C6 and C7 and 2 with fracture in C7） were analyzed retrospectively in this study. For the preoperative American Spinal Injury Association （ASIA） classification, Grade C was found in 3 cases and Grade D in 5 cases. Screws were placed on the lateral masses and the first thoracic pedicle with Margerl technique. Lamina or facet bone allografting was used to achieve a long-term stability. Results: All the 8 patients were followed up for 5-37 months （mean: 15 months）. No operative death occurred. There were no examples of aggravation of spinal cord injury or vertebral artery injury, cerebrospinal fluid leak, nerve roots injury, screw malposition or back-out, loose of alignment or implant failure. Clinical symptoms and ASIA classification were improved in all the patients. Postoperative MRI scanning confirmed the satisfactory screw placement in all the cases. Conclusions: Lateral mass plates and pedicle screws through posterior approach are safe and beneficial for patients with lower cervical spine C6 or C7 injury.展开更多

For the management of posterior malleolus fractures, more studies are still required, though it is already well-recognized for medial and lateral structure. Therefore, fracture of posterior malleolus is striking subject of study among orthopedic surgeons. Most orthopedic surgeons recommend fixing the posterior malleolus fracture if it is larger than 25% to 33% of the distal articular surface. Further attention is required for the reduction and fixation of fractures involving posterior malleolus. Several approaches and methods for fixation of posterior malleolus have been defined in the literature. Previously, the most common method of fixation of the posterior malleolus is by indirect reduction and antero-posterior screws, it is minimally invasive, the anterior incision does not allow satisfactory visualization of the fragment, so good anatomical reduction is difficult to achieve thorough this approach. Operative management goals to reach a stable ankle with maximal function, decrease the risk of post-traumatic degenerative changes, and diminish the risk of complication. Nowadays, posterolateral approach is gaining the popularity due to adequate visualization and accurate anatomic reduction.展开更多

The mean observation period was 36 mo. The age, sex, body mass index(BMI), time from admission to surgery, length of hospitalization, outcome after discharge, walking ability, duration of surgery, blood loss and complications were compared. RESULTS: There was no significant difference in the age, sex, BMI, time from admission to surgery, length of hospitalization, outcome after discharge, duration of surgery and blood loss between the two groups. Two weeks after the operation, assistance was not necessary for walking in the hospital in 65.0% of the patients in the DAA group and in 33.3% in the PA group(P < 0.05). As for complications, fracture of the femoral greater trochanter developed in 1 patient in the DAA group and calcar crack and dislocation in 1 patient each in the PA group.CONCLUSION: DAA is an approach more useful for BHA for femoral neck fracture in elderly patients than total hip arthroplasty in terms of the early acquisition of walking ability.展开更多

Methods: Retrospective analysis of 17 cases of elderly patients with Anderson II odontoid fracture who underwent posterior pedicle screw fixation combined with iliac bone grafting from January 2013 to December 2016. 17 patients had a history of trauma before surgery, and they all have varying degrees of atlantoaxial instability or subluxation and varying degrees of neck occipital pain and limited mobility. Result: No spinal cord or vertebral artery injury occurred during surgery. Follow-up information is complete. The follow-up period was 6 to 48 months (mean 27.4 ± 12.4 months). Postoperative imaging review prompted a good reduction of cervical spine, stable sequence;no pedicle screw loosening, fracture, iliac bone graft at the location of the situation, odontoid fracture and bone healing at the good, the patient after cervical rotation are limited to varying degrees. Conclusion: Posterior pedicle screw fixation combined with iliac bone grafting in elderly patients with Anderson II odontoid fracture can achieve good stability, and the prognosis is good, but long-term cervical rotation function may be affected to varying degrees.展开更多

These techniques were being alternative to the standard anterior approach with less morbidity and mortality. Patients and Methods: This study was performed between 2011 and 2014 on 100 patients with acute unstable thoracolumbar spine fractures which were divided into four groups: 30 patients underwent (TLIF), 28 patients underwent (PLIF), 28 patients underwent (PA) and 14 patients underwent (TPA). Neurological outcome, complications, operative times, kyphotic angle, vertebral height loss, spinal canal compromise, pulmonary functions, Denis pain and work scale, VAS score, ODI score, hospital stay, and estimated blood loss (EBL) were evaluated and compared in between the four groups. Results: There was a higher complication rate, increased EBL, and longer operative time with posteroanterior (PA) compared with PLIF, TLIF and (TPA). Patients undergoing PLIF, TLIF and TPA had a greater recovery of neurological function than those in whom PA were performed. Conclusion: TPA appeared to have more favorable results in improving the clinical and radiological outcome and no complications were reported apart from superficial wound infection which healed rapidly. The PLIF, TLIF and TPA appeared to have a comparable morbidity rate to PA. The different methods of anterior reconstruction from posterior approach are more favorable, applicable and convenient than PA approach.展开更多

文摘BACKGROUND The anatomical features of the atlantoaxial spine increase the difficulty of complete and safe removal of atlantoaxial intradural extramedullary(IDEM)tumors.Studies concerning surgical interventions via a posterior approach are limited.AIM To investigate the safety and efficacy of atlantoaxial IDEM tumor resection using a one-stage posterior approach.METHODS We retrospectively analyzed clinical databases for one-stage atlantoaxial IDEM tumor resection via a posterior approach between January 2008 and January 2018.The analyzed data included tumor position,histopathological type,pre-and postoperative Japanese Orthopedic Association(JOA)scores and Nurick grades,postoperative complication and recurrence status.RESULTS A total of 13 patients who underwent C1-C2 Laminectomy and/or unilateral facetectomy via the posterior approach were enrolled in the study.In all cases reviewed,total tumor resection and concomitant C1-C2 fusion were achieved.The average follow-up was 35.3±6.9 mo(range,26-49 mo).A statistically significant difference was noted between the preoperative JOA score(11.2±1.1)and the score at the last final follow-up(15.6±1.0)(P<0.05).A statistically significant difference was noted between the preoperative Nurick grade(2.3±0.9)and that at the last follow-up(1.2±0.4)(P<0.05).However,no statistically significant difference was noted between the preoperative and last follow-up C1-2 Cobb angle and C2-7 Cobb angle(P>0.05).No mortalities,severe complications or tumor recurrence were observed during the follow-up period.CONCLUSION Total resection of atlantoaxial IDEM tumors is feasible and effective via a posterior approach.Surgical reconstruction should be considered to avoid iatrogenic kyphosis and improve spinal stability and overall clinical outcomes.
文摘BACKGROUND Spinal meningiomas(SMs)are common benign tumors that are typically treated with surgical resection.The choice of surgical approach may vary depending on the location of dural attachment of the SM,with a posterior approach being the traditional preference.However,there is limited research available on the impact of dural attachment location on outcomes following posterior approach for SM resection.The average age of the included 34 patients’(10 males and 24 females)age was 62.09 years.Mean follow-up duration was 22.65 months.The location of SM was the thoracic spine in 32 cases,with only 2 in the cervical spine.On average,intraoperative blood loss was 520.59 mL,and operating time was 176.76 minutes.Thirty three cases had successful outcomes while only 1 experienced an unexpe-cted outcome.The tumor recurrence rate was 2.9%.After surgery,there were 3 cases of cerebral spinal fluid leakage,1 case of pneumonia,and 1 case of urinary tract infection.Dural attachments were predominantly found dorsal or dorso-lateral(13 cases),followed by ventral or ventrolateral(14 cases),and lateral(7 cases).The outcomes among these subgroups were similar.CONCLUSION The posterior approach for SM resection is safe and effective,yielding comparable surgical and neurological outcomes regardless of the dural attachment location.
文摘The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood.Dislocation,a severe complication associated with increased mortality and often requiring additional surgery,may occur less frequently with the direct anterior approach compared to the posterior approach.Careful consideration of patient demographics is essential when planning the surgical approach.Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.

文摘Objective: to study and analyze the clinical value of posterolateral anterior spinal canal decompression combined with injured vertebral internal fixation in the treatment of thoracolumbar burst fracture. Methods: forty patients with thoracolumbar burst fractures admitted to our hospital from April 2018 to December 2020 were randomly divided into study group and control group with 20 cases in each group. The control group was treated with short-segment minimally invasive internal fixation combined with injured vertebral bone graft, and the study group was treated with posterior approach anterior spinal canal decompression combined with injured vertebral internal fixation. The perioperative conditions, postoperative vertebral height, endplate angle and bony fusion of the two groups were evaluated and compared. Results: the operation time of the study group was shorter than that of the control group, and the amount of hemorrhage was less than that of the control group. At the stage of 12 months after operation, the height of the vertebral body in the study group was higher than that of the control group, and the endplate angle was smaller than that of the control group. The difference was statistically significant (P < 0.05). There was no significant difference in the osseous fusion between the two groups (P > 0.05). Conclusion: posterior anterolateral spinal canal decompression combined with internal fixation for thoracolumbar burst fractures has less intraoperative bleeding, which can reduce the risk of vertebral height loss and vertebral deformity on the basis of ensuring the effect of bony fusion.

Cosmetic results were excellent in 22 patients in the anterior approach group and 20 patients in the posterior approach group. Conclusion: Posterior Campbell approach is simpler than anterior Henry approach, but it creates additional soft tissue damage that can affect the circulatory status and hence possible osteonecrosis of the trochlea and a higher percentage of limitation in joint mobility. While the anterior approach is technically more demanding, but it gives better functional results.
文摘Background Cervicothoracic junction spinal tuberculosis （CJST） in children is uncommon, especially when accompanied by a huge abscess. However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children. Methods Ten pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months. Results The patients were followed-up for an average of 26 months （range, 15-32 months）. There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° （range, 30-52°） before the operation to 18° （range, 12-26°） post-operation. Neurological function was improved in all patients. Conclusions Combined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.
文摘Objective: To treat injury of the lower cervical spine C6 to C7 with cervical lateral mass plates and T1 pedicle screws through posterior approach. Methods: The data of 8 patients with lower cervical spine C6 or C7 injury （6 patients with fracture and dislocation in C6 and C7 and 2 with fracture in C7） were analyzed retrospectively in this study. For the preoperative American Spinal Injury Association （ASIA） classification, Grade C was found in 3 cases and Grade D in 5 cases. Screws were placed on the lateral masses and the first thoracic pedicle with Margerl technique. Lamina or facet bone allografting was used to achieve a long-term stability. Results: All the 8 patients were followed up for 5-37 months （mean: 15 months）. No operative death occurred. There were no examples of aggravation of spinal cord injury or vertebral artery injury, cerebrospinal fluid leak, nerve roots injury, screw malposition or back-out, loose of alignment or implant failure. Clinical symptoms and ASIA classification were improved in all the patients. Postoperative MRI scanning confirmed the satisfactory screw placement in all the cases. Conclusions: Lateral mass plates and pedicle screws through posterior approach are safe and beneficial for patients with lower cervical spine C6 or C7 injury.
文摘[Objective]This study was designed to describe the fracture patterns and early results of operations of posterior Pilon fractures through a posterolateral approach.[Method]This study consisted of 14 cases,10 males and 4 females with the mean age of 47 years(range,28-63 years).The causes were traffic accident in 2,falling in 6 and sprain injuries in 6 cases.The duration from injury to operation was 7-14 days.Including 12 cases combined with distal fibula fracture and3 cases with medial malleolus fracture.There were 3 posterior dislocation fracture.All cases were treated with open reduction and internal fixation(ORIF).[Result]A consistent fracture pattern was identified with a primary,inferiorly posterior Pilon fracture that likely occur through a combined rotational and axial load mechanism.The average duration of follow-up was 26(range,24-37)months.The postoperation average of American Orthopedic Foot Ankle Society score(AOFAS)was 92points which was much higher than before operation.Anatomical reduction were obtained in all cases.Two complications(1wound superficial infection and 1 sural cutaneous nerve injury)were all managed nonoperatively.[Conclusion]Posterior Pilon fractures form a consistent pattern.They can be successfully managed through a posterolateral approach with direct reduction and buttress fixation of articular fragments.
文摘AIM:To study our novel caudal approach laparoscopic posterior-sectionectomy with parenchymal transection prior to mobilization under laparoscopy-specific view.METHODS:Points of the procedure are:(1) Patients are put in left lateral position and posterior sector is not mobilized;(2) Glissonian pedicle of the sector is encircled and clamped extra-hepatically and divided afterward during the transection;(3) Dissection of inferior vena cava(IVC) anterior wall behind the liver is started from caudal.Simultaneously,liver transection is performed to search right hepatic vein(RHV) from caudal;(4) Liver transection proceeds to the bifurcation of the vessels from caudal to cranial,exposing the surfaces of IVC and RHV.Since the remnant liver sinks down,the cutting surface is well-opend;and(5) After the completion of transection,dissection of the resected liver from retroperitoneum is easily performed using the gravity.This approach was performed for a 63 years old woman with liver metastasis close to RHV.RESULTS:RHV exposure is required for R0 resection of the lesion.Although the cutting plane is horizontal in supine position and the gravity obstructs the exposure in the small subphrenic space,the use of specific characteristics of laparoscopic hepatectomy,such as the good vision for the dorsal part of the liver and IVC and facilitated dissection using the gravity with the patient positioning,made the complete RHV exposure during the liver transection easy to perform.The operation time was 341 min and operative blood loss was 1356 mL.Her postoperative hospital stay was uneventfull and she is well without any signs of recurrences 14 mo after surgery.CONCLUSION:The new procedure is feasible and useful for the patients with tumors close to RHV and the need of the exposure of RHV.
文摘Posterior malleolus fractures are quite common and usually result from rotational ankle injuries. For the management of posterior malleolus fractures, more studies are still required, though it is already well-recognized for medial and lateral structure. Therefore, fracture of posterior malleolus is striking subject of study among orthopedic surgeons. Most orthopedic surgeons recommend fixing the posterior malleolus fracture if it is larger than 25% to 33% of the distal articular surface. Further attention is required for the reduction and fixation of fractures involving posterior malleolus. Several approaches and methods for fixation of posterior malleolus have been defined in the literature. Previously, the most common method of fixation of the posterior malleolus is by indirect reduction and antero-posterior screws, it is minimally invasive, the anterior incision does not allow satisfactory visualization of the fragment, so good anatomical reduction is difficult to achieve thorough this approach. Operative management goals to reach a stable ankle with maximal function, decrease the risk of post-traumatic degenerative changes, and diminish the risk of complication. Nowadays, posterolateral approach is gaining the popularity due to adequate visualization and accurate anatomic reduction.

文摘AIM: To evaluate whether walking ability recovers early after bipolar hemiarthroplasty(BHA) using a direct anterior approach.METHODS: Between 2008 and 2010, 81 patients with femoral neck fracture underwent BHA using the direct anterior approach(DAA) or the posterior approach(PA). The mean observation period was 36 mo. The age, sex, body mass index(BMI), time from admission to surgery, length of hospitalization, outcome after discharge, walking ability, duration of surgery, blood loss and complications were compared. RESULTS: There was no significant difference in the age, sex, BMI, time from admission to surgery, length of hospitalization, outcome after discharge, duration of surgery and blood loss between the two groups. Two weeks after the operation, assistance was not necessary for walking in the hospital in 65.0% of the patients in the DAA group and in 33.3% in the PA group(P < 0.05). As for complications, fracture of the femoral greater trochanter developed in 1 patient in the DAA group and calcar crack and dislocation in 1 patient each in the PA group.CONCLUSION: DAA is an approach more useful for BHA for femoral neck fracture in elderly patients than total hip arthroplasty in terms of the early acquisition of walking ability.
文摘Objectives: To explore the treatment and related prognosis of elderly patients with Anderson II odontoid fracture with posterior pedicle screw fixation combined with iliac bone grafting. Methods: Retrospective analysis of 17 cases of elderly patients with Anderson II odontoid fracture who underwent posterior pedicle screw fixation combined with iliac bone grafting from January 2013 to December 2016. 17 patients had a history of trauma before surgery, and they all have varying degrees of atlantoaxial instability or subluxation and varying degrees of neck occipital pain and limited mobility. Result: No spinal cord or vertebral artery injury occurred during surgery. Follow-up information is complete. The follow-up period was 6 to 48 months (mean 27.4 ± 12.4 months). Postoperative imaging review prompted a good reduction of cervical spine, stable sequence;no pedicle screw loosening, fracture, iliac bone graft at the location of the situation, odontoid fracture and bone healing at the good, the patient after cervical rotation are limited to varying degrees. Conclusion: Posterior pedicle screw fixation combined with iliac bone grafting in elderly patients with Anderson II odontoid fracture can achieve good stability, and the prognosis is good, but long-term cervical rotation function may be affected to varying degrees.
文摘Background: The different methods of anterior reconstruction and posterior instrumentation in surgical management of thoracolumbar spine fractures are PLIF, TLIF, lateral extracaviatary and transpedicular techniques which are increasingly used to perform partial or total corpectomies and anterior reconstructions from a posterior approach. These techniques were being alternative to the standard anterior approach with less morbidity and mortality. Patients and Methods: This study was performed between 2011 and 2014 on 100 patients with acute unstable thoracolumbar spine fractures which were divided into four groups: 30 patients underwent (TLIF), 28 patients underwent (PLIF), 28 patients underwent (PA) and 14 patients underwent (TPA). Neurological outcome, complications, operative times, kyphotic angle, vertebral height loss, spinal canal compromise, pulmonary functions, Denis pain and work scale, VAS score, ODI score, hospital stay, and estimated blood loss (EBL) were evaluated and compared in between the four groups. Results: There was a higher complication rate, increased EBL, and longer operative time with posteroanterior (PA) compared with PLIF, TLIF and (TPA). Patients undergoing PLIF, TLIF and TPA had a greater recovery of neurological function than those in whom PA were performed. Conclusion: TPA appeared to have more favorable results in improving the clinical and radiological outcome and no complications were reported apart from superficial wound infection which healed rapidly. The PLIF, TLIF and TPA appeared to have a comparable morbidity rate to PA. The different methods of anterior reconstruction from posterior approach are more favorable, applicable and convenient than PA approach.
