Anatomical Dimensions of the Proximal Carpal Tunnel Entrance and Its Relationship With Carpal Tunnel Syndrome
Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy in humans. It is characterized by paresthesias in the median nerve (MN) area, distal to the carpal tunnel (CT). It is more common in middle-aged women. Its incidence increases with repetitive manual activity and obesity, although its ultimate etiology is not well known. Our aim was to determine the ultrasound anatomical dimensions of the proximal CT entrance and their relationship with sex, age, anthropometric data, MN, and the presence or absence of CTS and to assess their possible etiological role in this neuropathy.
Methods: We analyzed the anatomical measurements of the proximal entrance of 793 CTs using ultrasound—height, width, and ellipsoid area—in patients with CTS (578) and in healthy subjects (215). We also analyzed their relationships with age, sex, height, weight, dominant hand, and degree of nerve involvement.
Results: The three anatomical variables studied at the proximal entrance of the CT were height (12.63 ± 1.44 mm), width (22.06 ± 2.01 mm), and ellipsoid area (173 ± 22 mm2). All three measurements studied were higher in cases than in controls and in male than in female. Height and area were strongly associated with the degree of MN involvement.
Conclusions: These results suggest that the proximal CT entrance is a site of adaptability rather than the site of greatest biomechanical stress within the CT in the pathophysiology of CTS.
期刊介绍：
Acta Neurologica Scandinavica aims to publish manuscripts of a high scientific quality representing original clinical, diagnostic or experimental work in neuroscience. The journal''s scope is to act as an international forum for the dissemination of information advancing the science or practice of this subject area. Papers in English will be welcomed, especially those which bring new knowledge and observations from the application of therapies or techniques in the combating of a broad spectrum of neurological disease and neurodegenerative disorders. Relevant articles on the basic neurosciences will be published where they extend present understanding of such disorders. Priority will be given to review of topical subjects. Papers requiring rapid publication because of their significance and timeliness will be included as ''Clinical commentaries'' not exceeding two printed pages, as will ''Clinical commentaries'' of sufficient general interest. Debate within the speciality is encouraged in the form of ''Letters to the editor''. All submitted manuscripts falling within the overall scope of the journal will be assessed by suitably qualified referees.
