Outcomes for Pauwels' Osteotomy in Nonunions of Displaced Femoral Neck Stress Fractures: A Case Series.

Femoral neck stress fractures (FNSF) are rare injuries and have shown poor results after displacement, including nonunion and osteonecrosis (ON). The goal of this study was to retrospectively evaluate a series of patients who underwent a valgus producing intertrochanteric osteotomy for FNSF nonunion and assess the degree of Pauwels' correction, ON rate, and return to duty. Current functional outcomes were prospectively obtained via a telephone script.
