Selvan et al. identified six cannulated hip screw configurations in use clinically and tested each in synthetic femoral neck osteotomy models to determine which geometry provides the strongest, most stable fixation for intracapsular hip fractures.
When placing cannulated screws for intracapsular femoral neck fractures, use a triangular configuration with the apex screw positioned superiorly — avoid two- or three-screw vertical-line patterns, which this study showed provide significantly less resistance to peak and ultimate failure loads.
