Description
Onder and colleagues compared two scoring systems that grade how well a broken hip is realigned during surgery, asking which one better predicts a screw cutting out of the bone afterward. Their 2026 retrospective study covered 108 patients aged 65 and older treated with the same femoral nail for unstable hip fractures.
Patients averaged 79 years of age, and 69.4% were women, with cutout occurring in 15 cases, or 13.9% of the group. The Chang criteria predicted cutout more accurately, reaching an AUC of 0.79 on a scale where higher means better prediction, versus 0.68 for the Baumgaertner criteria. The authors describe the Chang system as the more complete biomechanical tool but call for larger multi-center studies before routine adoption.
