Abstract

Endoscopic carpal tunnel release (ECTR) continues to rise in popularity as a treatment option for carpal tunnel syndrome. Numerous variations in technique and instrumentation currently exist, broadly classified into two-portal and single-portal techniques with antegrade and retrograde designs. ECTR is equally effective as open carpal tunnel release for alleviating symptoms of carpal tunnel syndrome with no differences in long-term outcomes. ECTR has an increased risk of transient nerve injury, whereas open carpal tunnel release has an increased risk of wound and scar complications. ECTR has higher direct costs but is associated with earlier return to work. ECTR is a safe and effective approach to carpal tunnel release in the hands of experienced surgeons.
