Roentgenogrammetric analysis demonstrated a more intensive development in the II and III metacarpal hand bones, as well as in the forearm bones in karatists comparing to those in boxers and football players. The transversal diameter of the medullary cavity was less in the karatists. Visual analysis of the roentgenograms demonstrated presence of sesamoid bones in the area of the proximal interphalangeal joints II and III in the fingers of the karatists, waist thickening on the medial surface of the proximal and middle digital phalanges, a sharp thickening of the compact substance layer in the area of the inferior third of the medial surface of the ulnar bone.
