Scapular neck fractures are oftenstudied as case reports mostly accompanied by other injuries, thus leading toconfusion. All previous cases of scapular neck fractures are not associated withrotator cuff injuries.CASE SUMMARY A 62-year-old man was admitted to our emergency department 6 h after his rightshoulder and back were impacted by heavy objects. The patient presented chesttightness and shortness of breath. Chest computed tomography (CT) showedpneumohemothorax, multiple rib fractures, and right scapula fractures. ThreedimensionalCT reconstruction of the right shoulder joint showed a trans-spinousscapular neck fracture with a glenohumeral joint dislocation. Rotator cuff injurywas suspected because the patient had a glenohumeral joint dislocation and wasthen confirmed by shoulder magnetic resonance imaging. A staged surgery wasperformed, including open reduction and internal fixation of the right scapulafracture and repairing of rotator cuff by right shoulder arthroscopy. At the 5-mofollow-up, the fracture line was blurred and the shoulder joint function was good.CONCLUSION Fracture of the scapular neck combined with rotator cuff tear is rare and therotator cuff injury should not be ignored in clinical work. Stable internal fixationcombined with secondary arthroscopic repair of rotator cuff tear can achieve goodresults.展开更多

Thus, we evaluated how the contralateral trapezius compound osteomuscular flap transfer would work in stabilizing lateral scapular winging, and the case is reported here. A literature review was also conducted, and articles relevant to the case are presented.CASE SUMMARY A 37-year-old male patient who had sustained an isolated dorsal scapular nerve injury underwent reconstructive surgery using the contralateral trapezius compound osteomuscular flap transfer technique to treat scapular winging and the consequent pain, and to restore function from the shoulder impairment. As a result, the involved shoulder showed an improved Constant-Murley score, from19.5% to 81.88%.CONCLUSION Contralateral trapezius osteomuscular flap transfer succeeded in stabilizing scapular winging in this case, improving shoulder function and affording pain relief.展开更多

Several studies have reported successful outcomes with non-operative treatment of scapula fractures. Although non-operative treatments are successful in a very high percentage of patients, very few cases of non-union of scapular body fractures have been reported. In our review of the literature, we found two case reports of scapular body fractures developed into non-unions. In both of these cases, open reduction and internal fixation with reconstruction plates and bone graft was successful at eliminating pain and restoring function. This is a case report of a patient with a symptomatic, extra-articular scapular body defect from a non-union that was treated successfully with an acellular dermal extracellular matrix and bone graft using a novel展开更多

The 58 patients who met the criteria had 65 arthroplasties: 18 with a Grammont-type prosthesis(Grammont group) and 47 with a lateral-based prosthesis(lateral-design group). We compared the groups by rates of scapular notching and instability and by radiographic markers of glenoid position and tilt. We also compared glenoid sphere sizes and the number of subscapularis tendon repairs between the groups. Rates were compared using the Fisher exact test. Notching severity distribution was compared using the χ2 test of association. Significance was set at P < 0.05.RESULTS The Grammont group had a higher incidence of scapular notching(13 of 18; 72%) than the lateral-design group(11 of 47; 23%)(P < 0.001) and a higher incidence of instability(3 of 18; 17%) than the lateral-design group(0 of 47; 0%)(P = 0.019). Glenoid position, glenoid sphere size, and subscapularis tendon repair were not predictive of scapular notching or instability, independent of implantdesign. With the lateral-based prosthesis, each degree of inferior tilt of the baseplate was associated with a 7.3% reduction in the odds of developing notching(odds ratio 0.937, 95%CI: 0.894-0.983). CONCLUSION The lateral-based prosthesis was associated with less instability and notching compared with the Grammonttype prosthesis. Prosthesis design appears to be more important than glenoid positioning.展开更多

The first description of ultrasound-guided dorsal scapular nerve blockade using a single-shot local anesthetic technique for the diagnosis and treatment of neck pain is reported. A 38-year-old female patient presented with neck pain, and the history and clinical examination strongly suggested myofascial pain affecting the middle scalene muscle. The pain had been unresponsive to pharmacological therapy or physiotherapy. After identifying the dorsal scapular nerve (DSN) in the body of the middle scalene muscle, an ultrasound-guided nerve block was performed using a single injection of local anesthetic to alleviate the patient’s pain. It has been demonstrated that the dorsal scapular nerve can be identified in the neck and effectively blocked using ultrasound guidance. This technique has the potential to assist in the diagnosis and treatment of neck pain originating from the middle scalene muscle.展开更多

文摘To explore the treatment methods for scapular fractures associated with clavicle fractures.Methods Of 23 cases with scapular fractures associated with clavicle fractures,13 treated conservatively took the function exercise of shoulder joint after two months and 10 treated with open reduction and plate fixation reconstruction began the function exercise of shoulder joint four weeks after operation.The follow up averaged 12 months.Results All patients were healed up.18 cases were followed up,of them 8 cases were treated surgically,10 cases,conservatively.Of eight cases treated surgically,seven got excellent functional recovery of the shoulder joint and one satisfactory.In the meantime,of 10 cases treated conservatively,the recovery of shoulder joint was excellent in six,good in three and poor in one.Conclusion As for scapular fractures with associated clavicle fractures,open reduction and plate fixation reconstruction is a good treatment method for it can keep the stability and the balance of shoulder joint and is helpful for early functional exercise and recovery of the shoulder joint.7 refs,5 figs.
文摘The subscapular system can confer numerous flaps for the reconstruction of composite mandibular defects.This chapter aims to review the indications,advantages,and anatomy of subscapular system flaps in the reconstruction of the mandible.The subscapular system can serve as an alternative to the fibula free flap in the presence of significant atherosclerotic disease or other contraindications.The flexibility and abundance of its soft tissue components make this system particularly advantageous for complex composite defects.Avoiding a fibula free flap for osseous reconstruction of the mandible permits early patient mobilization and may prevent adverse postoperative complications.A long pedicle can be harvested with subscapular flaps,which may prove useful in the face of limited available recipient vessels.Critics of the subscapular system cite longer operative times due to the need for patient repositioning and concerns over the integrity of the bone stock.Positioning modifications may permit a two-team approach to subscapular reconstruction,thus limiting operative times.Subscapular harvest does incur shoulder morbidity;however,this does not appear to affect the quality of life significantly.The flap is reliable and can support endosseous implants if properly planned,though it may be more susceptible to bone resorption when compared to the fibula.Overall,the subscapular system remains a versatile donor that can achieve ideal reconstructive outcomes with minimal morbidity.
文摘目的观察苍龟探穴针刺法与肩胛带稳定性训练治疗肩袖损伤的临床疗效及对肩外旋角的影响。方法将100例肩袖损伤患者随机分为单一组和联合组,每组50例。单一组采用肩胛带稳定性训练干预方案,联合组在单一组的基础上采用苍龟探穴针刺法。观察两组治疗前后美国肩肘外科协会(American Shoulder and Elbow Surgeons,ASES)评分、疼痛视觉模拟量表(visual analog scale,VAS)评分、肩周激痛点(myofascial trigger point,MTrP)数量、肩关节活动度及健康调查简表(MOS 36-item short-form health survey,SF-36)评分的变化,并比较两组临床疗效。结果联合组的总有效率为92.0%,高于单一组的70.0%(P<0.05)。两组治疗后ASES评分均升高(P<0.05),且联合组高于单一组(P<0.05)。两组治疗后VAS评分均降低(P<0.05),且联合组低于单一组(P<0.05)。两组治疗后MTrPs数量均减少(P<0.05),且联合组少于单一组(P<0.05)。两组治疗后肩关节活动度均增大(P<0.05),且联合组大于单一组(P<0.05)。两组治疗后SF-36评分均升高(P<0.05),且联合组高于单一组(P<0.05)。结论针刺联合肩胛带稳定性训练可有效缓解肩袖损伤患者肩部疼痛,促进肩关节功能恢复。
