Removal of cancellous bone graft through the base of the excised radial styloid process

In performing STT arthrodesis, the excision of the tip of the radial styloid avoids further radial styloid impingement. Cancellous bone graft can be obtained through the base of the excised radial styloid, using a trephine or a curette. The amount of bone removed is sufficient for intercarpal arthrodesis.
