Failure on attempted removal of a Gamma nail in two young patients

Abstract

We experienced failures in attempting to remove a Gamma nail and a long Gamma nail, both of which were used for fixation of a subtrochanteric fracture in two young patients. We suspect that new bone forms in the notch, which is located beneath the screw thread in the lag screw, and causes jamming of the lag screw in young patients after fracture consolidation.
