A total of 107 peritrochanteric fractures were treated operatively, with the Gamma Nail in 45 cases and Compression Hip Screw (CHS) in 62.
Fracture stability was assessed by the Evans' classification system.
At final review, sliding of the lag screw with the Gamma Nail averaged 4.6mm in stable fractures and 5.6mm in unstable fractures. The CHS showed an average sliding of 2.1mm in stable fractures and 9.0mm in unstable fractures. In unstable fractures, decreased sliding is seen with the lag screw of the Gamma Nail compared with that of the CHS.
