An association between the inferior humeral head osteophyte and teres minor fatty infiltration: evidence for axillary nerve entrapment in glenohumeral osteoarthritis.
Glenohumeral osteoarthritis often results in inferior humeral osteophytes. Anatomic studies suggest that the axillary neurovascular bundle is in close proximity to the glenohumeral capsule. We therefore hypothesize that an inferior humeral osteophyte of sufficient magnitude could encroach on the axillary nerve and result in measurable fatty infiltration of the teres minor muscle. ⋯ These data are consistent with our hypothesis that the axillary nerve may be entrapped by the inferior humeral osteophyte often presenting with glenohumeral osteoarthritis. Entrapment may affect axillary nerve function and lead to changes in the teres minor muscle. Axillary neuropathy from an inferior humeral osteophyte may represent a contributing and treatable cause of pain in patients with glenohumeral osteoarthritis.

Comparative StudyAcute surgical treatment of acromioclavicular dislocation type V with a hook plate: superiority to late reconstruction.
Outcomes for patients with acromioclavicular joint dislocation, Rockwood type V, treated with acute or delayed hook plate surgery were investigated. ⋯ Patients treated with acute surgery had a more satisfactory outcome than those with late surgery after failed conservative treatment.

Improvement in shoulder rotation in complex shoulder fractures treated by reverse shoulder arthroplasty.
Reverse shoulder arthroplasty in complex shoulder fractures is now a common practice. Unfortunately, loss of rotation is observed when tuberosity excision is used, impairing function and patient satisfaction. The purpose of this study was to evaluate the advantage of tuberosity repair in terms of the functional result. ⋯ Management of complex fractures of the superior extremity of the humerus by reverse shoulder arthroplasty is an accepted approach, but such treatment is restricted to elderly patients. Shoulder rotational ability is improved by systematically repairing the tuberosities around the implant. However, their consolidation should be anatomic; otherwise, the result is impaired by the lack of rotation. Nonunion or malunion does not lead to a functional disaster, as is sometimes the case with hemiarthroplasty without tuberosity healing.
