BACKGROUND: We hypothesized that there are several common risk factors associated with secondary carpal tunnel releases. Therefore, we chose to investigate these common factors by analyzing the charts of those patients requiring a second carpal tunnel release (CTR) procedure. METHODS: A retrospective chart review was performed, and patients were identified by searching hospital medical record databases using the Common Procedural Terminology. RESULTS: Between January 1, 2000, and March 31, 2004, 2357 patients had a primary CTR, and 48 of them were found to have had a secondary CTR (of these 48, 9 had diabetes mellitus, 11 had hypertension, and 6 had gastrointestinal-related illnesses). Seven percent of those who had an open release primarily required a second CTR, while only 0.2% of those who had an endoscopic release primarily required a second CTR. CONCLUSION: A greater number of secondary CTR procedures were required for those patients with symptoms of carpal tunnel syndrome in the group that had an open release primarily versus those that had an endoscopic release primarily. Diabetes mellitus and hypertension may also contribute to the need for secondary surgery.
