Sažetak
Ample movements and the permanent loading of feet in the nonphysiological position in ballet dancers bring about multiple morphological and functional changes in the course of years. The authors studied the changes in the tarsal bones of fifty ballet dancers (32 female and 18 male dancers) with dancing experience of more than ten years by means of X-rays of the ankles and tarsal hones. The control group consisted of 32 females and 18 males of the corresponding age and weight who had never been ballet dancers. The change, were most pronounced in the talus, which was shorter and more bowed in dancers than in the control group. Similar changes were found in the calcaneal, navicular and cuboid bone. By measuring the maximal plantar and dorsal flexions as well as the eversion and inversion of the feet, the authors tried to find out how the morphological changes of the tarsal bone and ligaments affect the mobility of ankle joints. In comparison with the control group the most striking difference was observed in the plantar Hexion of the foot. The mobility of joints increased by several degrees in all movents after exercising or dancing. Most injuries of the lower part of the leg and foot in ballet dancers relate to ligaments, tendons and joint capsules, while bone injuries occur more rarely. Very often the transverse and longitudinal arches arc lowered and arthritic changes observed in foot joints. The changes and injuries of the tarsal hone and foot joints depend upon the constitutional form of the foot and the duration of the dancing period.
