ABSTRACT
BACKGROUND: This study aims at investigating the outcome and electrophysiologic recovery of 150 carpal tunnel syndrome hands after single-portal endoscopic surgery. METHODS: Patients with the cross-sectional area of the median nerve being 13-15 mm2 on ultrasound or abnormal sensory nerve conduction velocity on EMG are assigned to endoscopic surgery that cuts the decompressing transverse ligament to avoid the emergence of severe symptoms, such as muscular atrophy and loss of hand function. RESULTS: Single-portal endoscopic release is a safe and efficacious option for carpal tunnel release. The findings demonstrate encouraging results. CONCLUSION: The endoscopic carpal tunnel release with the placement of a MicroAire system is a safe and effective method for treating carpal tunnel syndrome.
