Femoral Neck Fracture Non-Union: Treatment with Bone Marrow Concentrate, Demineralized Bone Matrix, and Morselized Allograft and Angular Stable Fixation. Report of 2 Cases.

Introduction: Femoral neck fractures in young adults, particularly Pauwels' 3 fractures with angles exceeding 70°, pose challenges in determining optimal surgical interventions due to limited clinical trial data. Complications such as avascular necrosis, non-union, and shortening hinder the healing process. Existing fixation methods, including multiple cannulated screws and sliding hip screws, have shown non-union rates of nearly 9% in young patients.
