title: The nerve supply of the trapeziometacarpal joint.
abstract: Ten forearm and hand specimens from fresh cadavers were dissected and examined under magnification for articular branches to the trapeziometacarpal joint arising from the thenar and palmar cutaneous branches of the median nerve, the superficial branch of the radial nerve and the lateral cutaneous nerve of forearm. In all but one specimen the thenar branch of the median nerve sent an articular branch to the trapeziometacarpal joint. Multiple branches from the palmar cutaneous branch of the median nerve, the superficial branch of the radial nerve and the lateral cutaneous nerve of forearm were also found. All these branches need to be divided during a "complete" denervation of the trapeziometacarpal joint.
