A Rare Presentation of Giant Cell Tumour of Distal Ulna - Wide Resection and Reconstruction Using Proximal Fibula and TFCC Reconstruction Using Palmaris Longus Tendon

Abstract

Giant cell tumour of the bone (GCT) is a rare locally aggressive primary bone tumour with an incidence of 3% to 5% of all primary bone tumours. The most common location for this tumour is the long bone meta-epiphysis especially of the distal femur, proximal tibia, distal radius, and the proximal humerus. Involvement of distal ulna is rare accounting for 0.45% to 3.2%. Considering local aggressive nature and high recurrence, wide resection is the treatment recommended. Instability of ulnar stump and ulnar translation of the carpals are known complications following resection of distal ulna. To overcome these problems, we attempted a newer technique of distal ulna reconstruction using proximal fibula and TFCC reconstruction using Palmaris longus tendon following wide resection of giant cell tumour of distal ulna in a 44-yearold male. This technique of distal radio ulnar joint reconstruction has excellent functional results with no evidence of recurrence after one-year follow-up.
