En-bloc excision of Giant Cell Tumors of the distal radius and arthrodesis of the translocated ipsilateral ulna: A report of two cases

The distal radius is the third most common site of giant cell tumor of bone (GCTB). The local aggressive invasion of this rare neoplasm requires reconstructive solutions after wide excision. The authors present two cases of patients diagnosed with Campanacci grade III GCTB of the distal radius successfully treated with en-bloc excision and translocation of the ipsilateral ulna. Pre-operative application of denosumab was given for one year to both patients. At one year of follow-up, both patients are disease-free and reported satisfactory results on Quick - Disabilities of the Arm, Shoulder and Hand (Quick-DASH) questionnaire and modified Musculoskeletal Tumor Society (MSTS) score. Although a challenge, the reported procedure offers good oncological and functional outcomes.
