This exhibit depicts right-hand ulnar neuropraxia and neuroplasty to restore nerve function. Neuropraxia is the temporary loss of sensory and motor functions due to a disruption in nerve conduction. Pre-Operatively, a sutured laceration present on the right palm in the area of the ulnar nerve. Numbness is present in the small finger and the ulnar half of the fourth finger.
The small finger also has signs of clawing, lack of abduction, and ulnar neuropathy. A zig-zag incision is made from the flexor carpi ulnaris tendon to approximately 3 cm past the laceration. The branches of the ulnar nerve are then dissected from surrounding structures. Dissection was carried out from the area of injury, past the hook of the hamate. An ulnar nerve contusion was observed with no evidence of laceration.
