Open reduction and internal fixation of fractures of the radial head.
The purpose of this retrospective study was to analyze the functional results following open reduction and internal fixation of fractures of the radial head and to determine which fracture patterns are most amenable to this treatment. ⋯ Although current implants and techniques for internal fixation of small articular fractures have made it possible to repair most fractures of the radial head, our data suggest that open reduction and internal fixation is best reserved for minimally comminuted fractures with three or fewer articular fragments. Associated fracture-dislocation of the elbow or forearm may also compromise the long-term result of radial head repair, especially with regard to restoration of forearm rotation.

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.
