Carpal tunnel syndrome (CTS) is the most commonly diagnosed and treated entrapment neuropathy. Surgical treatment involving the clearance of the flexor retinaculum is widely employed. Open, minimally-invasive and endoscopic surgical techniques have all been described as treatment options for CTS and short-term success with these methods is well established. Long-term studies, however, are scarce and usually evaluate only clinical signs and symptoms. The objective of this study is to evaluate patients treated by a palmar incision and by the use of the Paine retinaculatome (6 years post-op minimum; mean is 98 months). We assessed palmar, pulp to pulp, lateral and tridigital prehension strength using a dynamometer. Finger sensitivity was measured using nylon monofilaments. We observed that while sensitivity improved with time, grip and prehension strength remained unchanged.
