We report the case of a 31-year-old woman who had had the distal end of the
ulna resected for a giant cell tumour five years before presenting with a
further one in the hamate. The medullary cavity of the hamate was curetted
and cancellous bone grafted from the distal radius. Hel symptoms resolved,
and 26 months postoperatively the cortex of the hamate was fully restored.
