Predictive Outcomes for Selective Thumb Carpometacarpal Joint Denervation

To summarize, a Wagner incision is made starting over the junction of the glabrous and non-glabrous skin overlying the thumb CMC joint extending toward the distal wrist crease. The branches of the superficial radial nerve are identified as lying perpendicular to the plane overlying the fascia of the thenar muscles. The branches of the lateral antebrachial cutaneous nerve are identified and resected within the anatomic snuffbox deep to the first compartment. Finally, the thenar muscle fibers are divided at their proximal origin to identify the articular branches of the posterior cutaneous branch of the median nerve.
