Long-term complications of open carpal tunnel release

Abstract

Fifty patients who underwent open carpal tunnel release (OCTR) surgery at least 12 months earlier for carpal tunnel syndrome were reviewed, focusing on scar tenderness, pillar pain, and symptoms of neuroma. A total of 55 hands were studied. At an average of 20.2 months of follow-up, 5.5% had Tinel's sign, 7.3% had scar tenderness, 12.7% had pillar pain, and 18% had burning discomfort. Pillar pain was elicited in a much higher fraction of patients by using the "table test" (provocation of pillar pain by having the patient lean with his/her weight on the hands placed on the edge of a table), even when traditional tests were negative. Symptoms and signs are present in a substantial number of patients after OCTR, even after almost 2 years of follow-up. Patients should be informed of the incidence of long-term symptoms and signs after OCTR surgery. © 2008 Wiley Periodicals, Inc.
