Masquelet Technique for Salvage of Failed Vascularized Fibular Graft Nonunion After Humeral Tumor Resection

Case: Diaphyseal nonunions after bone tumor resection present a significant reconstructive challenge. We report a 39-year-old woman who developed a diaphyseal humeral nonunion after giant cell tumor resection and reconstruction with vascularized fibula graft. She presented with symptomatic segmental bone loss and hardware failure. Two-stage Masquelet-induced membrane procedure was performed, resulting in complete union and excellent functional recovery at 12 months postoperatively. Conclusion: This case highlights the potential of the Masquelet technique in reconstruction of refractory nonunions despite previous failed reconstructive attempts.
