Juxta-articular giant cell tumors can pose major surgical challenges. Aggressive distal radius giant cell tumors often require complex reconstructive procedures that are associated with numerous complications. We present a case of a 25-year old man with a Campanacci grade 3 giant cell tumor of the distal radius that was successfully treated with denosumab without complex reconstructive procedures. At 3.5-year follow-up and 1-year drug free period, the patient remained asymptomatic without histologic evidence of recurrent tumor. With denosumab therapy, patients can potentially avoid surgery and achieve a successful outcome.
