The intertrochanteric hip fracture. A retrospective analysis.
One hundred intertrochanteric hip fractures were analyzed utilizing a computer-assisted digitization system to study the factors affecting postoperative stability. Fractures were evaluated by measuring shortening and angulation, collapse of telescoping device when utilized, and migration of the fixation device within the femoral head. Fractures were classified preoperatively according to their stability and postoperatively according to the type of operative reduction performed. The failure rate and postoperative stability were then compared according to the type of fracture, type of operative reduction, and internal fixation device utilized. Results indicate that the preoperative fracture classification is a strong and significant determinant of postoperative stability. Conversely, the type of operative reduction was not as significant a determinant of postoperative stability. In particular, medial displacement osteotomy had no advantage over anatomic reduction in the unstable fracture. The use of a fixed angle nail plate was associated with an increased failure rate.
