The Treatment of Reverse Obliquity Intertrochanteric Fractures With the Intramedullary Hip Nail

Abstract

The lesser trochanteric fragment and posteromedial defect in 31-A3.3 fracture seems to play an important role in the stability after intramedullary hip nailing. The causes of fixation failure in the PFN group were associated with excessive sliding of femoral neck screw, which was aggravated by toggling motion in the 31-A3.3 fractures.
