Abstract

The purpose of our study is to make a follow-up evaluation of endoscopic carpal tunnel release under focal anesthesia using the Wolf single portal system. A total of 65 patients with a mean age of 50 years undergoing 79 procedures were retrospectively studied. Preoperative complaints, intraoperative findings, and postoperative results of all the patients were recorded. Follow-up was conducted at 1, 5, 12, and 24 weeks and at 1 year postoperatively. Wound pain, analysis of satisfaction, Levine functional status scales, and surgical complications were included. No patients sustained iatrogenic neurovascular injury or hematoma formation. The average Levine functional severity score decreased from 2.82 points preoperatively to 1.2 points at the most recent survey. One case recurred at 1 year after the surgery and subsequently underwent open release. Surgery using the Wolf single portal system under focal anesthesia is a safe and efficacious option for endoscopic carpal tunnel release.
