We aimed to investigate the clinical characteristics of slipped capital femoral epiphysis (SCFE) in patients aged less than 10 years and identify the efficacy of physeal-sparing procedures in this age group. Demographic data of 18 SCFE patients aged less than 10 years were compared with those of 71 older patients to investigate the clinical characteristics. The efficacy of physeal-sparing procedures (n=5) was investigated compared with that of in-situ screw fixation (n=13). Obese children were noticeably more common among SCFE patients aged less than 10 years (P=0.034). The slip angle improved significantly more in the physeal-sparing subgroups (P=0.038) without the occurrence of further slippage. Moreover, physeal-sparing procedures allow persistent growth of the proximal femoral physis. However, most of the patients in the physeal-sparing subgroup needed additional surgeries when the proximal femoral physis outgrew the implant. Obesity may be associated more with early-onset SCFE (onset<10 years). Physeal-sparing procedures are safe and effective in preventing leg-length discrepancy and allowing the remodeling of the deformed proximal femur in this age group.
