Treatment of periprosthetic femoral fractures with modular stems.

Purpose: The purpose of this study was to analyse the efficacy of modular femoral stems for the treatment of certain post-operative periprosthetic fractures in patients with hip arthroplasty.

Methods: Of a total series of 61 modular revision stems, 17 were used to address periprosthetic femoral fractures and 12 of these are the object of this study. The average follow-up was 3.

Charnley low-friction arthroplasty of the hip. Five to 25 years survivorship in a general hospital.

Background: Some studies have raised the question about whether the good results obtained with the Charnley prosthesis could be replicated at general hospitals when it comes to the frequency of early complications and failure rates, both of which would be higher than those published by centres devoted to hip arthroplasties.

Methods: We reviewed the results of 404 Low Friction Arthroplasties of the hip implanted between 1976 and 1993 in a general hospital by general orthopaedic surgeons. For the survival analysis, the end-point chosen would be the chirurgical revision of any of the prosthetic components for whatever reason.

Total knee arthroplasty in the elderly. Is there an age limit?

The goal of this study was to compare the results of the total knee arthroplasty (TKA) in 2 study groups only differing by age. We have analyzed 218 TKA cases (138 women and 80 men) with at least 2 years follow-up. Mean age was 70 years (SD, 7.
