Abstract
Introduction: The aim of this prospective study was to determine the prevalence of neuropathy in diabetic patients undergoing foot and ankle surgery. It was hypothesized that the prevalence of diabetic neuropathy is higher among patients who undergo foot and ankle surgery compared with historical rates of neuropathy in diabetic patients in general. Methods: During a consecutive 42-month period, patient data were prospectively entered for 1859 consecutive patients undergoing foot and ankle surgery. Among the subjects, 394 had been previously diagnosed with diabetes mellitus (DM), and the remaining 1465 did not have DM. Results: The prevalence of neuropathy in patients with and without DM was 77.2% (304 of 394 patients) and 11.7% (172 of 1465 patients), respectively. Patients with diabetic neuropathy were older, had poorer glycemic control, had higher serum creatinine levels, and reported more significant tobacco use than diabetic patients without neuropathy. Conclusion: Nearly 80% of diabetic patients undergoing foot and ankle surgery at a large academic medical center had diabetic neuropathy. Preoperative recognition of this morbid complication of DM is important to appropriately stratify those diabetic patients into a high-risk category.
