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
