Abstract

In Vietnam, carpal tunnel syndrome has been increasingly studied, primarily focusing on clinical and paraclinical features or surgical outcomes. However, there is currently a paucity of research on the anatomical characteristics of the transverse carpal ligament (TCL). Our study aimed to describe the dimensions of the TCL in adult Vietnamese cadavers. The results showed that the proximal width of the TCL was 35.2 ± 3.2 mm, and the distal width was 25.7 ± 2.1 mm. The ulnar length of the TCL measured 16.2 ± 1.6 mm, which was longer than the radial length of 12.9 ± 3.1 mm and the central length of 12.1 ± 2.5 mm. The thickness of the TCL varied across different points, with the thickest point being 1.3 ± 0.2 mm at the midpoint between the hamate bone and the distal edge of the TCL. Our study provides anatomical data on the TCL that may serve as a valuable reference for surgical treatment in carpal tunnel release procedures.
