Abstract

A retrospective analysis of postoperative fracture collapse was performed using data from 142 patients with intertrochanteric hip fractures fixed anatomically with sliding screws. Of the 142 patients, 80 had unstable, three- or four-part hip fractures. Significant collapse (as defined by strict radiographic criteria relating the height of the femoral head to the greater trochanter and by Doppelt's criteria) was seen in 26 of the unstable fractures. The degree of collapse was classified as type I (minimal), type II (moderate), and type III (severe). Average follow-up was 31 months. An in- depth clinical and radiographic analysis was performed evaluating pain, limp, abductor weakness, and leg-length discrepancy. The numerical degree of both vertical and horizontal fracture collapse was also analyzed. Of the patients with moderate or severe collapse, 93% had a poor functional result, whereas all the patients with minimal collapse remained asymptomatic. Although postoperative fracture impaction of hips fixed with sliding screws may promote early healing, a high rate of union, and a low rate of hardware failure, excessive collapse is a problem that needs to be addressed.
