dynamic hip screw [DHS] in stable trochametric fractures and experimental study

ABSTRACT

An experimental study of the behavior of stable trochanteric fractures fixed with the dynamic hip screw under static loading was performed using twenty dry adult cadaveric femora. Fracture impacting occurred with screw sliding but was associated with some forward rotation of the proximal fragment around the screw axis. The implant bone assembly was found stable to loading higher than the average physiologic load of an average man. The clinical relevance of this study is that patients with stable trochanteric fractures fixed with the dynamic hip screw can safely do early weight-bearing
