Giant Cell Tumor of Distal Ulna - A Rare Case Report

Among the benign primary bone tumors, Giant cell tumor (GCT) accounts for about 3% to -5%. It is a locally aggressive tumor with maximum incidence between 20 to and 40 years of age. The sites where GCT is most commonly seen are distal femur, and proximal tibia followed by distal end radius. Distal end of ulna is a rare site with an incidence of only 0.45% to -3.2%.

We report a case of a 32- year- old male with (GCT) giant cell tumor of the left distal ulna. We managed the patient with en bloc resection of distal ulna along with reconstruction of distal radio ulnar joint (DRUJ) and triangular fibro cartilage complex (TFCC) using proximal fibula graft and palmaris longus graft. DRUJ was stabiliszed with a k- wire.

After 1 year of follow- up, patient showed good results in terms of range of movements of the wrist joint with no evidence of recurrence.
