Vascularized Medial Femoral Condyle Periosteal Flaps With Allograft Bone for Distal Radius Giant Cell Tumors

Case: Distal radius reconstruction after giant cell tumor (GCT) resection is typically performed with free fibular flaps when a vascularized bone is needed. However, vascularized fibular flaps are contraindicated in patients with peroneal artery variants. We present 2 patients with GCTs of the radius and bilateral peronea arteria magna who underwent resection with wrist fusion using an allograft bone and vascularized free medial femoral condyle periosteal flaps. Both patients had excellent outcomes with minimal postoperative morbidity. Conclusion: Allograft bone with vascularized medial femoral condyle periosteal flaps is an effective option for reconstructing distal radius defects after GCT resection when conventional methods fail.
