Abstract

PURPOSE
Endoscopic carpal tunnel release has gained popularity as a primary surgical option for carpal tunnel release. The purpose of this study was to evaluate the complication of endoscopic carpal tunnel release using modified Chow's extrabursal dual-portal technique in a large cohort in a single center.
METHODS
Data of 2,248 wrists in 1,438 patients who underwent endoscopic carpal tunnel release by the extrabursal dual-portal technique were collected retrospectively from 2000 to 2016. Clinically, postoperative symptom was assessed, and complications were reported.
RESULTS
At the final follow-up, the complication rate was 2.8% including digital nerve injury and tendon injury. Except for 16 hands, the patients showed recovery from the initial symptoms.
CONCLUSION
Extrabursal modified Chow's dual-portal technique is a reliable and safe method to treat carpal tunnel syndrome with minimal complications.
