IntroductionThe endoscopic assisted release for cubital tunnel syndrome (CuTS) gained popularity in recent years with unclear long-term results. This study aims to evaluate long term results regarding functional and subjective outcomes after endoscopic assisted release for the CuTS.Materials And MethodsThirty one patients who have been treated by endoscopic assisted release for CuTS between 2006 and 2013 were followed up both clinically and with a questionnaire with a mean follow up of 152 months (range 120-204 months). Functional and subjective parameters were evaluated and statistically compared to the contralateral elbow. For statistical evaluation one-sample t-test and the McNemar test were defined as appropriate.ResultsPinch grip strength, two-point discrimination, application of Semmes-Weinstein monofilaments, Tinel's sign, grip and three-point pinch strength showed no significant difference. The DASH score was 14,2 with 96,6% of patients rating good/excellent results.ConclusionsThis study found the endoscopic assisted release of the ulnar nerve to be an efficacious and safe method for the treatment of CuTS.© 2024.
