Objective: To investigate the frequency of tarsal tunnel syndrome (TTS) in the diabetic neuropathy patients. Method: Electrodiagnostic study was performed to diagnose diabetic neuropathy and tarsal tunnel syndrome (TTS) in 56 patients (male 25, female 31) with diabetes mellitus. The frequency of combined TTS in diabetic neuropathy patients was calculated. Results: Out of 56 diabetic patients, 52 patients were diagnosed as diabetic peripheral neuropathy. The frequency of concomitant TTS was 22 cases in 52 diabetic patients with diabetic neuropathy. Conclusion: In diabetic neuropathy group, the frequency of TTS was higher than general population.
