Hip Desarthrodesis - Report of Three Cases

Abstract

Abstract Hip desarthrodesis, which is the conversion of an arthrodesis or of a surgical bone fusion into a hip replacement arthroplasty, is a difficult and challenging operation because of the need of a joint reconstruction in cases with bone fusion and an often long-term immobilization between the femur and the acetabulum,with important anatomic changes, retractions of adjacent soft tissues, and an associated limb shortening. Hip arthrodesis is an operation performed less and less; consequently, its desarthrodesis is even rarer. The present report details three rare cases of patients with long-termhip arthrodesis who were submitted to hip replacement conversion arthroplasty; it describes the applied surgical techniques and their clinical and functional outcomes.
