[Epiphysiolysis in cattle]

Rentgenologically and clinically established cases of epiphysiolysis and apophysiolysis are described. They are observed primarily in cattle aged from 7--8 months to three years. Highest percentage of epiphysiolysis cases has been established with the distal epiphysis of the metatarsal bones (82.6%), and a negligible one has been observed (3 cases) in the distal epiphysis of the metacarpal bones. A single case has been established in the distal part of the tibia. The case of apophysiolysis concern the apophysis of the heel processus, tuber calcanei. Contributing factors are said to be the mechanical and traumatic influences, and predisposing ones are the distrubances in the bone-formation processes.
