Abstract

An 18-year-old female patient presented with complaints of motor function and sensory impairment of the ulnar nerve on the 9th day after primary repair with a laceration of the right palm. We performed nerve wrapping with silicone tube after primary nerve repair to prevent neuropathy due to scar formation. As a result of surgical treatment, motor function and sensory impairment of ulnar nerve were improved significantly without complication until 2 years postoperatively. Nerve wrapping with silicone tube can be widely used in patients who underwent primary repair of ulnar nerve and patients who have undergone surgical decompression due to other causes of Guyon's canal syndrome. This surgical technique is expected to prevent neuropathy caused by scar formation.
