vs. male. Note: a total of 150 images (100 male, 50 female) have been used for this table. The mean long axis and short axis of each HB: a, b, c, d, e, and f; the mean distance between medial and lateral sesamoid bones: i; some mean angles on the first metatarsophalangeal joint: HVA, IMA, PASA, and DASA; the mean angel of instep: Meary and pitch.
