[Epiphysiolysis of the hip following radiotherapy of pelvic tumors in early infancy. Apropos of 5 new cases].

Five personal cases of slipped capital femoral epiphysis in children submitted to pelvic radiotherapy and nineteen similar observations are reported. This complication appears around 6 years after radiotherapy; its frequency increases with high radiations doses and associated chemotherapy. Weakening of the epiphyseal plate is probably involved whatever radiations voltages. Surgical treatments should be confined to epiphysis fixation. As this complication can secondarily affect the other hip, preventive controlateral fixation must be discussed.
