Early Recovery After Endoscopic vs. Short-Incision Open Carpal Tunnel Release

Endoscopic carpal tunnel release has been claimed to offer improvement in recovery time and postoperative discomfort over open carpal tunnel release. Short-incision open carpal tunnel release has been claimed to offer recoveries comparable with endoscopic techniques. Patients receiving carpal tunnel surgery were randomized to short-incision open release or single-portal endoscopic release. Preoperative and postoperative evaluation included grip and pinch strength measurements and patient completion of a questionnaire regarding symptoms and function. Thirty-six operated hands completed evaluation, including 22 endoscopic and 14 open releases. Early grip and pinch strength after endoscopic carpal tunnel release were improved significantly over short-incision open release (p < 0.05). Subjective evaluation indicated a trend toward improved symptoms and function with endoscopic over short-incision open carpal tunnel release. Endoscopic carpal tunnel release provides faster recovery of strength than short-incision open carpal tunnel release and improves early postoperative comfort and function to a small degree.
