Comment on Bao et al.: Lesser trochanteric osteotomy in total hip arthroplasty for treating CROWE type IV developmental dysplasia of hip

摘要

The greater trochanter fracture. The technique of lesser trochanteric osteotomy includes sequential bone cutting at the level of the subtrochanteric diaphysis, while leaving the greater trochanter intact, as shown in Fig. 1 in [1] this article. It is likely to cause a greater trochanter fracture when the femoral stem is inserted, which is going to compromise the abductor attachment. How can the greater trochanter be protected from being broken?The soft tissue tension. Subtrochanteric osteotomy has been demonstrated to be a safe and effective technique for soft tissue release in performing total hip arthroplasty (THA) for high dislocated developmental dysplasia of the hip (DDH).
