A rare case of distal ulna giant cell tumour Wide excision and stabilisation using extensor carpi ulnaris tendon

Abstract

Giant Cell Tumour is a common benign tumour of bone accounting for 3 to 5% of all primary bone tumour. It commonly affects in second decade of life between 18 years to 40 years. Distal ulna is less commonly affected site with reported incidence varying from 0.45% to 3.2%. The current available literature is non-conclusive regarding treatment protocol of distal ulna giant cell tumour and whether stabilization procedure of ulna is required or not after excision of distal ulna to avoid the symptoms of ulnar impingement syndrome. We are reporting a case of right distal ulna Giant cell tumour in 51 year old right hand dominant female patient who presented to us with persistent pain and restricted wrist movements. We performed a wide excision of tumour with dynamic stabilization of distal ulnar stump using extensor carpi ulnaris split tendon graft. We have 2 year follow up of the patient with no recurrence and a good functional outcome having a Mayo wrist score of 80.
