Abstract

Background: Carpal Tunnel Syndrome (CTS) is one of the most common pathologies in the daily life of hand surgeons. The classic content of carpal tunnel is well defined, but several anatomical alterations are described, whose incidence percentages differ in the literature. Methods: This prospective study evaluated patients submitted to carpal tunnel release by the conventional open approach. This study observed and described the surgical anatomy of these patients. This present study was approved by the hospital's Ethics Committee and by Plataforma Brasil. The study lasted six months, between July and December 2018. The sample consisted of patients with clinical symptoms of CTS, with complaints of nocturnal paresthesia or change in sensitivity in the territory of the median nerve in the hands and with positive clinical signs. The study sample consisted of 100 patients between 34 and 90 years old, 84 females and 16 males. Results: The extra canal findings presented 58 cases with musculature over the transverse ligament, of which 45 had small thickness and 13 had significant thickness. Two were identified as thenar musculature fixed in the hypothenar region. Intracanal findings presented 11 persistence of the median artery, and 2 presence of muscle bellies were visualized. Conclusion: there is divergence in the literature regarding the incidence of anatomical variations of Carpal Tunnel Syndrome among the most internationally relevant studies.
