The mechanical characteristics of the transverse carpal arch were studied using fresh-frozen human cadaveric wrists. Tensile properties of the ligaments involved in this structure were also analyzed. The flexor retinaculum did not prove to be a major factor in the maintenance of the carpal arch since its division only reduced the global transverse carpal arch stiffness an average of 7.5%. On the contrary, the transverse intercarpal ligaments connecting the bones of the distal carpal row were shown to have an essential role in providing stability to the carpal tunnel.
