Retrospective cohort of 395 patients with displaced intracapsular hip fractures treated by three-cannulated-screw fixation. Examines whether screw position on AP and lateral radiographs, screw spread, and angulation between screws predict nonunion.
When placing three cannulated screws for intracapsular femoral neck fractures, prioritize maximizing the spread of screws on the lateral view — this is the one positioning variable shown to significantly reduce nonunion risk.
Don't waste effort achieving perfect parallelism; the data show angulation between screws is irrelevant to healing.
