Tendon Harvest for Treatment of Radial Nerve Palsy Using Endoscopic Technique.

BACKGROUND: Endoscopic method for many surgeries with minimal access is proposed to be effective for preventing the excessive scar formation, reducing pain, cosmesis, and the early return to work. Surgical outcomes of endoscopic and open methods for tendon harvest in treatment of radial nerve palsy were evaluated.

METHODS: In a randomized single-blind clinical trial study, 10 patients with radial nerve palsy who referred to the Plastic Surgery Department of the Fatimah Zahra Hospital, Iran University of Medical Sciences, Tehran, Iran were divided into two equal groups. Flexor carpi radialis (FCR), flexor carpi ulnaris (FCU) and the palmaris longus (PL) tendons were harvested by endoscopic or open techniques. The outcomes (tendon harvest time, rate of post-surgical pain, amount of pain medication, patient satisfaction, amount of scar, and length of scar) are measured.

RESULTS: There was no significant difference in time of surgery between two methods. Vancouver scar scale, cosmetic satisfaction, severity of postoperative pain and also drugs for pain relief after tendon harvest surgery were significantly lower in endoscopic method than open method.

CONCLUSION: Regarding the low invasiveness, high satisfaction rate of patients, low pain severity, low scar and the little need for opiate to reduce pain in the endoscopic method, endoscopic tendon harvest technique for radial nerve palsy seems to have priority over open method.
