Total hip replacement after intertrochanteric osteotomy.

From 1980 to 1993 we inserted 216 total prostheses into hips which had been treated by varus and valgus-extension intertrochanteric osteotomy. The technique of the operation was more difficult than in hips operated on for the first time because of anatomical changes produced by the osteotomy in the surrounding structures. We have had complications which taught us how to prevent and deal with these problems.

Teicoplanin versus cefamandole in the prevention of infection in total hip replacement.

In a prospective, controlled, single-blind study the efficacy of teicoplanin versus cefamandole in preventing infections in total hip replacement was investigated in 496 consecutive patients. A single intravenous dose of teicoplanin (400 mg) was as effective as two intravenous doses of cefamandole (2 g before and 1 g after surgery). No major complications were observed in either group.

Patellar realignment in recurrent subluxations and dislocations: long-term results.

A total of 41 patients affected with recurrent subluxations or dislocations of the patella treated with different surgical methods between 1972 and 1981 were examined. Radiographic and clinical monitoring according to Crosby-Insall in 35 patients ranges from 10 to 20 years, with the following results: excellent: 17%; good: 69%; fair: 14%; poor: 0; recurrent dislocations or subluxations: 0.

[Loosening of total hip prosthesis].

The problem of total hip prosthesis is an immediate and long-term stability. An insufficient bone anchorage of the prosthesis produces a tissue reaction around the implant that causes a loosening. The hight incidence of loosening of cemented total prosthesis has spurred the research into uncemented implants.

Valgus-extension osteotomy for osteoarthritis of the hip. Indications and long-term results.

We reviewed the results of 277 intertrochanteric valgus-extension osteotomies performed between 1973 and 1975 for primary or secondary osteoarthritis. The average age of the patients was 51 years and follow-up varied from 11 to 15 years. At the latest evaluation 67% of the hips were good or excellent on the Merle D'Aubigné scale.
