Treatment of giant cell tumor of distal radius with vascular anastomosis with proximal graft of vascular

Abstract

Objective: To evaluate the curative effect of proximal fibula graft of vascular anastomosis for giant cell tumor(GCT) of distal radius of bone. Methods: 38 patients with distal radius GCT were treated with proximal articular graft of anastomotic vessels. We evaluated the wrist joint function before and after surgery using wrist activity, visual analogue scale(VAS)pain score, grip recovery rate and Cooney scoring system. Results: All patients' wounds healed in stage I, and recovered smoothly during the perioperative period. No obvious wrist deformity was observed during the follow-up period. Bony union was achieved at the tibial and humerus osteotomy ends. The average healing time was 11 weeks. At third month postoperatively, the patient's wrist motion ranged from dorsiflexion to palmar flexion (69.15±15.24)°, ulnar/spasm deviation was (22.74±10.55)°, grip strength was (88.69±12.75)%, wrist VAS pain The score was (2.45±1.11) points and the Cooney score was (89.58±11.25) points, which was significantly better than preoperation (all P<0.05). No recurrence or metastasis occurred during follow-up in all patients. Conclusions: Distal humerus GCT treated with distal radius with vascular anastomosis with proximal graft of vascular has little effect on the activity of the lower extremities. However, its reconstruction of the wrist joint function might achieve better results.
