[Anatomical quantification of the tibial part of the plantar aponeurosis]

The metrical analysis of the anatomical characteristics is important because of its objectiveness. As it is concerned with the organs belonging to the locomotor system, the metrical method of the bones has already been systematized by Martin (1928), whereas the same kind of method for use on other organs remains undeveloped. The author aims to establish the metrical method of the plantar aponeurosis. The method for measuring the tibial part of the aponeurosis developed in this paper is sufficiently applicable for obtaining its principal anatomical characteristics. The results show that the tibial portion of the plantar aponeurosis becomes statistically significantly wider and thinner in its anterior part, and that the thickness of the tibial portion of the aponeurosis in the anterior part is larger on the right side than on the left side.
