Revision total elbow replacement using the Souter-Strathclyde prosthesis.

The Souter-Strathclyde prosthesis was used in 52 evisions of total elbow replacements (TERs) between August 1986 and May 1997. Of these, 50, carried out in 45 patients, were prospectively followed for a mean of 53 months (14 to 139). The procedure produced reliable relief of pain, and the range of movement was preserved. There was a considerable incidence of adverse events associated with revision (30%), and 12 further procedures have been required. Nonetheless, a revision is the preferred salvage procedure for failed primary arthroplasty in the absence of sepsis.

Cementless acetabular replacement in the young. A 5- to 10-year prospective study.

This article presents a prospective clinical and radiologic review of 55 total hip replacements in 50 patients in which the cementless Harris-Galante porous-coated acetabular component was used. All patients were 50 years of age or younger. The cups were inserted by 15 different surgeons. The minimum followup was 5 years, with a mean of 7 years. No acetabular component has been revised for loosening, and none have migrated. Three (5.5%) cups have progressive bone-component radiolucent lines, two (3.6%) of which are complete. Six (10.9%) acetabular liners have been replaced for excessive polyethylene wear, and an additional four (7.3%) show sufficient wear to produce obvious radiographic eccentricity of the femoral head. All of the revised liners had 32-mm femoral heads and an initial polyethylene thickness of less than 6 mm. Although the results reflect excellent fixation of this component in the medium term, the incidence of exchange of the polyethylene liner for excessive wear is unacceptably high. The reduction in polyethylene thickness associated with the use of a metal-backed component and a 32-mm articulation was one of the factors contributing to the accelerated wear patterns seen in this series.

Candida infection of a silicone metacarpophalangeal arthroplasty.

Fungal infections following joint arthroplasty are extremely rare. Only 16 cases of Candida prosthetic infections have been reported, involving the hip, knee or shoulder joints. We report a case of a silicone metacarpophalangeal joint replacement complicated by a Candida albicans infection.

Carbon dioxide pneumothorax occurring during laparoscopic cholecystectomy.

A previously fit patient underwent laparoscopic cholecystectomy. During the procedure arterial oxygen saturation fell and clinical examination revealed signs of a right pneumothorax confirmed by chest X ray. Aspiration of the pleural cavity and analysis of the gas removed showed it to be composed entirely of carbon dioxide. Possible mechanisms of entry of carbon dioxide into the pleural space are discussed.
