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.

Is shoulder pain for three months or longer correlated with depression, anxiety, and sleep disturbance?
Recent studies have found a high prevalence of depression, anxiety, and sleep disturbance in patients with chronic musculoskeletal pain. We conducted a study to determine whether shoulder pain for 3 months or longer is correlated with depression, anxiety, and sleep disturbance. ⋯ Our study demonstrated high prevalence and close relationships of depression, anxiety, and sleep disturbance in patients with shoulder pain for 3 months or longer. These results may indicate importance of the psychologic approach as well as adequate pain control.

Comparative StudyFunctional outcomes of reverse shoulder arthroplasty compared with hemiarthroplasty for acute proximal humeral fractures.
Complex acute proximal humeral fractures may require prosthetic replacement of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative to hemiarthroplasty in the management of such fractures. This study compared the functional outcomes of RSA with hemiarthroplasty in patients with acute proximal humeral fractures. ⋯ Patients with acute proximal humeral fractures who undergo RSA appear to achieve superior 5-year functional outcomes compared with patients who undergo hemiarthroplasty.

Multicenter StudyCurrent strategies for the treatment of proximal humeral fractures: an analysis of a survey carried out at 348 hospitals in Germany, Austria, and Switzerland.
The therapeutic spectrum for the treatment of displaced proximal humeral fractures ranges from conservative therapy to head-preserving surgical interventions and joint replacement. This study initiated a survey on the current treatment options with regard to diagnostics, choice of therapy, and complications that are encountered at trauma surgeries and orthopedic hospitals in Germany, Austria, and Switzerland. ⋯ A preference for surgical treatment of proximal humeral fractures was found, with stabilization predominantly being attempted by the use of angle-stable implants. The 2 most common complications were "nonanatomic reduction of fractures" and the more specific problem of "implant perforation" when fixed-angle implants were used for treatment.
