The giant cell tumour of the proximal phalanx of the thumb treated by a 2-stage operation.

We present a 29-year-old woman who was treated for a giant-cell tumour of her thumb. Surgical treatment was performed in two stages. In the first stage, the tumour was removed and the first metacarpal and distal phalanges were fixed by an external fixator. In the second stage of reconstruction of the thumb, a cortico-cancellous bone graft from the iliac crest, an external fixator and double arthrodesis were used. This two-stage procedure provides the possibility for confirming the diagnosis and appropriate treatment choice and minimizes the risk of recurrence.
