RESUMO
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. Six patients underwent Pauwels' osteotomy for FNSF nonunion, and all went onto bony union. Three of the six patients progressed onto ON, with two patients requiring a total hip arthroplasty due to life-limiting symptoms. Pauwels' osteotomy is a reliable salvage procedure for FNSF nonunions. (Journal of Surgical Orthopaedic Advances 29(4):234-239, 2020).
