Screw trajectory affects screw cut-out risk after fixation for nondisplaced femoral neck fracture in elderly patients

Abstract

Our results suggested that fixation with nonparallel screws for nondisplaced femoral neck fracture in elderly and osteoporotic patients might interfere with shortening of the femoral neck along with fracture healing, leaving patients at risk of postoperative screw cut-out from the femoral head.
