Trochanteric Flip Osteotomy for Cranial Extension and Muscle Protection in Acetabular Fracture Fixation Using a Kocher-Langenbeck Approach

Abstract

This technique allows better visualization, more accurate reduction, and easier fixation of cranial acetabular fragments. Cranial migration of the greater trochanter after fixation with two screws is unlikely to occur because of the distal pull of the vastus lateralis muscle, balancing the cranial pull of the gluteus medius muscle.
