[Age-related changes of the bones of the leg, foot and ankle joint in pole-vaulters]

The data on age changes occurring in the height of the articular cleft of the talocrural joint, in morphological components of the diaphysis of the crus and foot bones have been presented in pole-jumpers and in non-sportsmen at the age of 13-21 years. Roentgenological, roentgenogrammetric and x-ray densitometric methods have been used. At the age of 14-15 years the greatest changes in the talocrural joint, crus and foot bones are noted.
