Anatomic procedures to treat disrupted CC ligaments using either CFBs or TGs resulted in an overall complication rate of 27.1% (16/59). Construct survivorship was calculated to be 86.2% at 12 months and 83.2% at 24 months. Good to excellent outcomes could only be reported in those patients who did not have a complication.

Injuries to the SC joint are uncommon. Recognition and classification of these injuries are critical to proper management, thus minimizing potential long-term sequelae such as posttraumatic arthritis and recurrent instability. Although nonoperative therapy is the modality of choice in anterior dislocations, posterior dislocations require special attention because of the presence of vulnerable posterior hilar structures. Surgical management of chronic instability and degenerative arthritis of the SC joint includes resection arthroplasty of the medial clavicle with or without reconstruction of the sternoclavicular ligaments with graft material. Although resection is typically performed open, an arthroscopic technique is described that theoretically decreases operating and recovery times while also decreasing the risk of iatrogenic injury. Currently, when reconstruction is needed for stability, a figure-of-8 graft reconstruction is the recommended method based on biomechanical data and small clinical series.

Snapping scapula syndrome, a likely underdiagnosed condition, can produce significant shoulder dysfunction in many patients. Because the precise origin is typically unknown, specific treatments that are effective for some patients may not be effective for others. Nevertheless, bursectomy with or without partial scapulectomy is currently the most effective primary method of treatment in patients who fail nonoperative therapy. However, many patients experience continued shoulder disability even after surgical intervention. Future studies should focus on identifying the modifiable factors associated with poor outcomes after operative and nonoperative management for snapping scapula syndrome in an effort to improve clinical outcomes and patient satisfaction.
