The soleal line in Thais.

ABSTRACT

A study on the soleal line was performed in 273 tibiae, 136 right and 137 left. The soleal line commences at a point 1-2 cm. below the fibular facet in 83.2 percent of the subjects. It ends slightly below the junction of the upper third with the middle third of the tibia in 85.0 percent of the cases. It generally shows mixed characteristics of a liner line, a wide line, a ridge or a groove in 82.4 percent. Right side or left side of either sex has no difference in accordance with this line. It appears as a ridge in male more than in female and shows a line in female more than in male. In males the characteristic of a ridge was found mostly at the lower third. Totally, the ridge character appears mostly in subjects of 40-49 of years of age, and the degree of the ridge is highest in this age range. The characteristic of a groove was found generally in the middle third, in 4.03 percent of the subjects.
