Novel Endoscopic Approach for Carpal Tunnel Syndrome: Functional Outcomes - A Prospective Study

Abstract

Abstract Introduction: Carpal tunnel syndrome (CTS), a common entrapment neuropathy, can cause debilitating symptoms affecting hand function and sleep. While conservative treatments are initially attempted, surgical intervention becomes necessary for severe cases. The study introduces endoscopic carpal tunnel release (ECTR) as a minimally invasive alternative to open procedures to enhance patient outcomes. Methods: A prospective study from January 2019 to January 2022 investigated arthroscope-assisted carpal tunnel release for CTS. Patients with chronic medical conditions were excluded. The surgical procedure involved local anesthesia, a 1.5 cm incision, flexor retinaculum release under arthroscopic guidance, and postoperative care. Outcomes were assessed using the Global Symptom Scoring Scale (GSS). Results: The affected population (n = 60) had a mean age of 47.58 years, with 42 females and 18 males. Common symptoms included numbness (43.3%), paresthesia (35%), and weakness (13%). Most patients (67.1%) had no comorbidities. Complications were minimal (5.0% paresthesia, 1.7% scar tenderness, and 3.3% infection). The mean preoperative GSS was 38.57, reducing significantly (P < 0.001) to 4.6 at 12 months’ follow-up. Conclusion: The study demonstrates the efficacy and safety of ECTR as a minimally invasive alternative for severe cases of CTS. With a low rate of complications and significant improvement in symptoms, including numbness, paresthesia, weakness, and surgeon expertise remains vital for successful outcomes.
