Abstract Objective: To evaluate ulnar and median nerves in diabetic patients by high resolution ultrasound (HRUS) and correlate these findings with nerve conduction study results. Design: Case control study. Subjects: 25 diabetic patients with peripheral neuropathy (Diabetic group) and 25 control ones (Control group). Methods: The cross-section area (CSA) of the median and ulnar nerves of both diabetic and control groups were measured at several certain points as well as their nerve conduction parameters. Results: The mean CSA of median and ulnar nerves were significantly higher in diabetic patients with Diabetic patients with peripheral neuropathy )DPN( than in control group. Conclusion: HRUS demonstrated a morphological change in patients with DPN in the form of an increase in CSAs which was statistically significant compared to control group of healthy individuals. Further studies with inclusion of larger number of patients, diabetic with and without neuropathy, are still needed |
