Abstract:[Objective] To evaluate the clinical indications and outcomes of microwave ablation and curettage for giant cell tumor in the distal radius. [Methods] A retrospective study was conducted on 8 patients who received microwave ablation and curettage for giant cell tu- mor in the distal radius in our hospital, including 2 males and 6 females, with an average age of (38.0±17.6) years, tumor diameter of (4.2± 0.8) cm, 3 cases of Campanacci grade II and 5 cases of grade III. [Results] All patients had operation performed successfully without serious complications such as nerve and blood vessel injury. With time of follow- up lasted for (64.4±27.7) months, the VAS score for pain and DASH score significantly decreased (P<0.05), while MSTS scores, wrist extension-flexion, radio-ulnar deviation and pronation-supination range of motion (ROM), as well as wrist grip strength significantly increased (P<0.05). Radiographically, all the 8 patients had the lesion re- moved completely without pathological fracture postoperatively, and no local recurrence or lung metastasis by the latest follow-up. [Conclu- sion] Microwave ablation and curettage is safe and achieves satisfactory preliminary results for Campanacci grade II~III giant cell tumor of the distal radius.
