Shoulder arthroplasty for the treatment of postinfectious glenohumeral arthritis.

Background: Shoulder arthroplasty after native shoulder infection is an uncommon problem with limited outcomes data. The purpose of this study was to evaluate the rates of reinfection and clinical outcomes after shoulder arthroplasty for the treatment of postinfectious glenohumeral arthritis.

Methods: Between 1977 and 2009, 24 shoulders underwent shoulder arthroplasty for postinfectious glenohumeral arthritis.

Non-Hodgkin's lymphoma of the knee diagnosed by arthroscopy.

We report a case of non-Hodgkin's lymphoma of the knee diagnosed by arthroscopy in an otherwise healthy, active 31-year-old woman. Plain radiographs were unremarkable and magnetic resonance imaging findings indicated the presence of a posterior horn medial meniscal tear. The patient underwent arthroscopy for a planned partial medial meniscectomy.

Reimplantation of a shoulder arthroplasty after a previous infected arthroplasty.

Currently, there is little information on the results of reimplantation after previous resection for an infected shoulder arthroplasty. The purpose of this study was to determine the rate of recurrent infection and clinical results. Between 1975 and 2000, 4 patients with a resection arthroplasty from a previously infected shoulder arthroplasty underwent subsequent reimplantation of a prosthesis.

Radiographic analysis of polyethylene glenoid components using modern cementing techniques.

The purpose of this study was to examine the initial radiographic appearance and changes occurring over time in patients who have undergone total shoulder arthroplasty by modern methods of bone preparation and current cement techniques. Sixty-five patients underwent seventy total shoulder arthroplasties by use of a cemented all-polyethylene, keeled glenoid component. The surface radius was equal to the radius of a one-piece humeral component.

Radial tunnel syndrome caused by ganglion cyst: treatment by arthroscopic cyst decompression.

Compressive neuropathies of the radial nerve at the elbow can lead to one of 2 clinical entities. Posterior interosseous syndrome is primarily a motor deficiency of the posterior interosseous nerve, and radial tunnel syndrome presents as pain along the radial tunnel and extensor muscle mass. The radial nerve can be compressed at a number of sites around the elbow.

Shoulder arthroplasty for the treatment of postinfectious glenohumeral arthritis.

Background: Currently, no studies on shoulder arthroplasty after a previous infection of the shoulder have been published, as far as we know. The purpose of this study was to evaluate the rates of reinfection and the clinical results after shoulder arthroplasty for the treatment of postinfectious glenohumeral arthritis.

Methods: Between 1975 and 2000, thirteen patients with a history of infection of the shoulder that resulted in severe glenohumeral arthritis underwent shoulder arthroplasty.
