A comparison of outcomes of carpal tunnel release for carpal tunnel syndrome in patients diagnosed with and without electrophysiological studies

Abstract

AbstractRecords were analysed from the institutional database, including 943 patients (1089 hands) with CTS who were operated on in the authors’ department over a period of four years (2012 to 2015). The diagnosis of CTS was made solely on the basis of clinical findings in 551 patients (58 %); 392 patients (42 %) also had electrodiagnostic tests performed, for various reasons. Patients were followed-up at 1 and 6 months with assessments that included the Levine scores, filament tests, grip and pinch strength. No significant differences in Levine scores were found at the 1 and 6 month assessments. Statistically significant differences were noted in 3-point pinch strength and sensation: however, these were not clinically meaningful. The results of the study show that the results of carpal tunnel release in patients with typical symptoms are no better after electrodiagnostic tests.
