Any secondary fragments can be stabilized with interfragmentary screw fixation in the usual fashion, including overdrilling when feasible.

As in any other fracture, bone grafting should be considered. The authors typically harvest from the dorsal metaphysis of the radius when cancellous bone is needed. In the rare instance when a corticocancellous graft is indicated (open fracture with significant bone loss), the first choice would be the volar radius from the area under the pronator quadratus.

Closure of the capsule and remainder of the wound is performed in the standard way. Reapproximation of the thenar musculature is advised. The hand is placed in a well-padded short arm thumb spica splint. The interphalangeal joint can be left free, which allows a modicum of tendon excursion and decreases the likelihood of adhesions.
