Abstract

Objectives: Evaluating results of functional and complications during and after treatment  giant cell tumors of the distal radius. Methods: We conducted a non-control intervention study, selected all 50 patients, aged 18 years and older with giant cell tumors of the distal radius treated by en bloc resection and reconstruction by non-vascularised proximal fibular autograft with distal radioulnar ligament reconstruction at Faculty of Musculoskeletal Pathology, Ho Chi Minh City Hospital of Trauma and Orthopedics from January 2010 - June 2020. Results:  Mean follow-up time was 51.9 ± 27.9 months. In wrist, average range of motion achieved at last follow-up was 25.9⁰ of palmar flexion, 49.7⁰ of dorsiflexion, 12.8⁰of tilt rotation, 29.7⁰ of tilt cylinder, 52.3⁰ of pronation turning, 68.4⁰ of supination. The holding power of the humped hand compared to the healthy hand had an average rate of 70%, compared with the hand with the same side without disease was 69.9%. All patients healed bone graft with an average time of 7.2 months and  100% of patients did not lose the joint of the lateral knee, the radio carpal and distal radioulnar joint. However, 14% of postoperative patients have complications with fracture and 6% have degenerative joint complications with degree 3. Conclusion: After treatment, patients giant cell tumors of the distal radius have good functional results. However, there are a number of cases with complications of fracture and degeneration after surgery.
