Outcome of carpal tunnel release surgery in patients with diabetes

Abstract

The surgical outcomes in 149 patients with diabetes and carpal tunnel syndrome who underwent transverse carpal ligament release surgery are reported. Associated factors such as insulin dependence, length of time with diabetes, electrodiagnostic studies, severity of neurological deficit, presence of polyneuropathy, and cervical disc disease were considered. Analysis of preoperative and postoperative symptoms, clinical findings, diagnostic studies, and patient self-assessment indicated that the majority of patients with diabetes experienced a favorable surgical outcome, regardless of any associated factors. Eighty-four percent of the patients reported good to excellent postoperative results in their hands. Further analysis of the subpopulation of insulin-dependent diabetics showed that 81% experienced good to excellent postoperative results. These results compare favorably with those of the control group: 200 nondiabetic patients, of whom 90% rated their results from carpal tunnel release surgery as good to excellent. There were no major complications in any group.
