[Roentgen morphology of sport injuries to the pelvic apophyses]

Pelvic apophyses are places of insertion of strong muscles and tendons and are therefore places of least resistance at the end of skeletal growth. Avulsions and disruptions of pelvic apophyses can be caused by overstrain during different kinds of sport activity. Typical radiological findings in 8 different cases of ruptures of apophyses, osteochondropathies, and resulting conditions of sport injuries are demonstrated. The difficulties of correct diagnosis and differential diagnosis are pointed out. The significance of hormonal impairment of ossification for development and stress factor of pelvic apophyses is exposed. Questions of treatment and follow-up studies are discussed.
