Prospective cohort of 214 patients with intertrochanteric hip fractures all treated with a 135° sliding compression hip screw, examining whether postoperative lateral femoral wall integrity predicts reoperation for technical failure within six months.
When you see an AO/OTA 31-A2.2 or A2.3 intertrochanteric fracture, recognize that one-third will sustain an iatrogenic lateral wall fracture if you attempt sliding hip screw fixation — strongly favor a cephalomedullary nail.
Intraoperatively, if the lateral wall fractures during drilling, completing the case with a sliding hip screw carries roughly an eightfold higher risk of mechanical failure requiring reoperation.
