VOLAR APPROACH TO THE BASAL JOINT OF THE THUMB (FOR BENNETT’S FRACTURE)

USES

This approach is a limited-use incision, used primarily to address volar pathology at the carpometacarpal (CMC) joint of the thumb, most commonly Bennett’s fracture, or for selected Rolando fractures. Some techniques for treatment of basal joint arthritis also use this incision.

ADVANTAGES

There are few structures at risk with this incision. The incision can be extended distally along the flexor carpi radialis tendon, after first diagonally crossing the wrist crease.

DISADVANTAGES

It is more difficult to see the ulnar side of the joint, where the nondisplaced fragment usually lies in a Bennett’s fracture.

STRUCTURES AT RISK

Dorsal sensory branches of the superficial radial nerve may cross the incision line.
