Abstract

Objective: The aim of this study was to compare the electrodiagnostic outcomes of carpal tunnel release in patients with and without diabetes with carpal tunnel syndrome (CTS), and to evaluate the effect of diabetes mellitus (DM) on electrodiagnostic outcomes. Method: We conducted a retrospective analysis of 67 patients with electro-diagnostic evidence of CTS. Patients were classified into two groups according to the presence of DM. Both groups were evaluated using nerve conduction studies preoperatively and 3 weeks and 3 months postoperatively. Results: There were no statistical differences in any of the electrodiagnostic parameters between groups 3 weeks postoperatively. However, there were statistical differences in the amplitude and the latency of compound muscle action potential, and sensory nerve conduction velocity 3 months postoperatively. Conclusion: Patients with DM did not show a significantly different outcome 3 weeks after surgery but showed a worse electrodiagnostic outcome 3 months after surgery than those without DM.
