P-NE003. Frequency of carpal tunnel syndrome in patients having diabetes mellitus with neuropathy in a tertiary care hospital

Abstract

Introduction. Carpal tunnel syndrome (CTS) is one of the most frequent entrapment neuropathies of the upper limb. Carpal tunnel syndrome (CTS) and diabetic polyneuropathy (DPN) are common conditions in patients with diabetes and therefore frequently occur concomitantly. Diagnosis of CTS in patients with DPN is important, as therapeutic interventions directed toward relief of CTS may be effective irrespective of diffuse neuropathy. Methods. This study was a hospital based descriptive cross sectional study done in BIRDEM general hospital between July, 2015 and June, 2016, for a period of twelve months. The initial clinical diagnosis of DPN was made and was confirmed by doing nerve conduction study. After having informed written consents, a standard preformed questionnaire was filled up for each case. Results. A total of 354 cases were finally analyzed with 153 (43.2%) patients being symptomatic and among those 54 (58.7%) had electrophysiology proven CTS. It was observed that 26.0% of patients established as having DPN also had CTS. The frequency of CTS among those with symptoms was significantly higher than in asymptomatic participants. Majority (38.4%) of patients belonged to the age group of 51-60 years. The mean age was found to be 55.99 ± 9.25 years with a range from 28 to 80 years. Among all cases of electrophysiology proven CTS (92 patients), females (53.3%) numbered greater in comparison to males (46.7%). Study subjects with CTS had significantly higher BMI, higher fasting blood sugar and higher HbA1c in comparison to patients without CTS. The mean compound motor action potential was not significantly different between patients with and without CTS. Conclusion. Given the high prevalence of CTS in subjects with DPN, it is recommended that therapeutic decisions should be made carefully after nerve conduction study and proper diagnosis.
