We reviewed 32 children with 41 radiation-therapy associated slipped capital femoral epiphyses (RTAS-CFE). Ten were from the authors' institutions and 22 from the literature. Gender distribution was equal. The age at diagnosis of the malignancy was 4.3 ± 3.1 years; the amount of radiation was 4,240 ± 1,445 rads. Children with RTASCFE presented younger (10.4 ± 3.2 years) than a routine SCFE. The average symptom duration was 5 ± 6 months. Children with RTASCFE are usually thin (median weight, 10th percentile) in contrast to children with typical SCFE, who are usually obese (<95th percentile). The majority (82%) of the slips were mild, compared to routine SCFEs (~50%); 28% were bilateral. There was a positive linear relationship between the age at presentation of the SCFE and the age at diagnosis of the malignancy; there was a negative linear relationship between the age at presentation of the SCFE and the amount of radiation therapy.
