Nerve Transposition

Primary repair of a nerve is preferable over nerve grafting when a tension-free environment can be achieved. The purpose of this cadaveric study was to evaluate the facility of nerve-gap closure gained by removing the hamate hook, eliminating the circuitous path of the motor branch of the ulnar nerve in the hand. Six cadaveric specimens were dissected and the length of the motor branch coursing through Guyon’s canal before and after hamate hook excision and nerve transposition was recorded. Average length was significantly shorter in specimens after transposition, with a mean 21% reduction relative to the nerve’s original course. This knowledge may help guide surgeons on whether excision of the hamate hook will allow for primary repair of the nerve when a segmental defect or retraction and scarring of the nerve stumps is encountered.

A compression lesion of the distal part of the terminal motor branch of the ulnar nerve is presented. One similar case has been previously described (McDowell, 1977) but some unusual features are recorded here. The reported clinical varieties of lesions of the ulnar nerve in the hand are listed (Table 1).

Fresh Frozen

Ten fresh frozen right cadaver arms were placed in a motorized jig and an in-situ ulnar nerve decompression was performed in 5 mm increments distally to the flexor carpi ulnaris (FCU) aponeurosis then proximally to the intermuscular septum. The elbows were ranged 0–135° after each incremental decompression and the ulnar nerve to medial epicodyle distance was measured to assess for nerve translation/subluxation compared with baseline (prerelease) values. None of the specimens had ulnar nerve subluxation (defined as anterior translation past the medial epicondyle) even after full decompression. Furthermore, there were no statistically significant ulnar nerve translations (defined as any difference in distance from ulnar nerve to medial epicondyle before and after each decompression) for any flexion angle or extent of decompression. This study provides biomechanical evidence that in situ ulnar nerve decompression from the FCU aponeurosis to the intermuscular septum does not result in significant ulnar nerve translation or subluxation.
