Giant cell tumour of hand bones: outcomes of treatment.

The purpose of this study was to report the incidence of giant cell tumour of the hand bones in an Asian population, document treatment options and report outcomes of treatment. Of 698 giant cell tumours of bone that underwent surgery between January 2011 and December 2020 at our institute, only 22 (3%) were in the hand. Fourteen occurred in the metacarpals, eight in the phalanges. Fifteen were primary tumours and seven had recurrent disease. Twenty lesions had an associated soft tissue component. Two patients treated for primary disease and one who had been treated for recurrence had local recurrence. Recurrence occurred in two of nine patients treated with curettage, one of three with resection and none of five with ray or digit amputation. Both curettage and resection/amputation are acceptable treatment options for the rare condition of giant cell tumour of bone in the hand, with a need to individualize treatment decisions based on the site and extent of disease to minimize treatment morbidity while maximizing disease control.
