Abstract:

Objective

Explore the clinical efficacy of endoscopic assisted incision of the transverse carpal ligament outside the carpal tunnel for the treatment of carpal tunnel syndrome， and evaluate the clinical effect of endoscopic single approach on postoperative palmar root pain and hand functional sensation recovery.

Methods

A retrospective analysis was conducted on 24 patients with carpal tunnel syndrome in Department of Hand Surgery of Xuzhou Renci Hospital from June 2021 to June 2023.A single transverse incision was made at the distal wrist crease， with simple expansion outside the carpal tunnel.The transverse ligament of the wrist was incised with endoscopic assistance， and postoperative palmar root pain， recovery of skin numbness in the median nerve innervation area， and thumb motor function were observed.The carpal tunnel syndrome assessment criteria recommended by Gu Yudong were applied to assess hand function and sensation.

Results

All 24 patients were followed up and their numbness symptoms improved one day after surgery.There was no infection in the incision and no columnar pain in the palm root.6 months after surgery，according to criteria of carpal tunnel syndrome， 19 cases were rated as excellent， 3 cases as good， and 2 cases as fair， with excellent and good rate of 91.67%.

Conclusion

The modified Okutsu method assisted by endoscopy is a safe and effective minimally invasive surgery for the treatment of carpal tunnel syndrome as a recommendable method， with reliable efficacy and short recovery time.
