Triplanar trochanteric osteotomy: a modified anterior trochanteric slide osteotomy.
Current methods of trochanteric sliding osteotomy typically preserve the lateral aspect of the greater trochanter, the vastus lateralis, the abductors, posterior capsule, and the external rotators. Our modification to this technique includes leaving an anterior vertical ridge of bone that resists the anterior-directed forces acting on the osteotomy. Furthermore, a chevron-shaped osteotomy provides some additional stabilization to the proximally directed pull of the abductors. We believe these modifications improve the intrinsic stability of the osteotomy, theoretically decreasing the rate of nonunion.
