Sarcoma Diagnosis and Treatment

Background: Recent progress in the chemotherapy and surgical procedures for osteosarcoma have enabled the preservation of limb function even when cancer occurs in the distal radius, a rare primary site of osteosarcoma. Case Report: We describe a case of osteosarcoma that occurred in an 18-year-old, male Kyudo (Japanese archery) archer’s left distal radius. Since the patient desired to resume Kyudo and the left hand was quite important for gripping a bow, we chose partial wrist arthrodesis (fibulo-scapho-lunate arthrodesis) with free vascularized fibular grafting (FVFG) as the reconstruction procedure following wide resection. After the wide resection, the major axis of bone defect was 8 cm. We harvested a free vascularized fibular graft with fascio-cutaneous flap with wide fascia to reconstruct the gliding surface of the extensor tendon. Fibula-proximal radius and fibulo-scapho-lunate fixation was performed by locking plates individually. Vascular anastomosis was performed between the radial artery and peroneal artery in a flow-through manner. Two peroneal veins were anastomosed with the radial vein and cephalic vein. Conclusion: Fibulo-scapho-lunate arthrodesis with FVFG may provide satisfied stability and function even in a Kyudo archer. The patient obtained sufficient wrist stability and grip strength, and could resume Kyudo.
