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.
