Interlocking Intramedullary Nail Fixation with Additional Bone Grafting from Trochanter Via a Femoral Hollow Trephine in the Treatment of Femoral Shaft Fractures: Design and Clinical Application.

The purpose of this study was to describe and evaluate the clinical application of the technique of interlocking intramedullary (IM) nailing via an entry point at the tip of greater trochanter using a specially designed femoral hollow trephine to stabilize diaphyseal fractures of the femur.
