Apophysis
Apophyses are bone attachments to tendons and ligaments . They have their own ossification center , which generally fuses with the main nucleus of the epiphysis , but sometimes remains independent.
In arthropods , an apophysis is an extension on the outer chitin skeleton .
Apophysiolysis
Since apophyses are still connected to the rest of the bone by cartilage tissue during growth, these processes can tear off under excessive stress ( apophysiolysis ). This happens particularly often with animals bred to have very strong body mass gains, with large breeds of dogs and domestic pigs . The upper end of the ulna , the greater trochanter of the femur, and the tibial tuberosity of the tibia are most commonly affected. The Osgood-Schlatter disease is an ossification .
In athletes, the apophyseal solution is occasionally seen on the ischium . The surgical refixation is unnecessary, very difficult and extremely complicated.
