We are not aware of any large published studies regarding the intermediate to long-term results of shoulder arthroplasty performed for the treatment of osteoarthritis after instability surgery. Therefore, we reviewed the results of this procedure, the risk factors for an unsatisfactory outcome, and the rates of failure in our patients. ⋯ The data from the present study suggest that shoulder arthroplasty for the treatment of osteoarthritis of the glenohumeral joint following instability surgery in this relatively young group of patients provides pain relief and improved motion but is associated with high rates of revision surgery and unsatisfactory results due to component failure, instability, and pain due to glenoid arthritis.

Comparative StudyDetermining humeral retroversion with computed tomography.
The purpose of this study was to develop and standardize a technique in which computed tomography images are used to determine the humeral torsion angle with landmarks that can be used during surgery. ⋯ Determining retroversion with computed tomography is more accurate than palpating the epicondylar axis or using the forearm as a goniometer during surgery. Computed tomography is useful for measuring the amount of rotation of humeri with a malunited fracture or severe arthritic deformity.
