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.
