Abstract
Great strides have been made in the field of total hip arthroplasty, but the issue of wear and osteolysis continue to be a problem, mostly for young adults. For this population varus rotational osteotomy still remains a viable alternative to total hip arthroplasty. The purpose of this prospective study was to describe the indications, the technique and the functional outcome of an isolated varus femoral osteotomy in 52 patients with hip dysplasia. We obtained very good results with a significant improvement of hip function and pain relief. We conclude that with appropriate selection of the patient the procedure may prevent or postpone the development of secondary osteoarthritis.
