Femur fracture in infants: A possible accidental etiology

Femoral fractures in nonambulating infants are generally felt to be attributable to abuse in the absence of significant trauma or underlying organic pathology. The investigation of such fractures includes a report to appropriate social service and law enforcement agencies, and legal involvement. This paper describes 2 nonambulatory infants who sustained identical oblique distal femoral metaphyseal fractures extending through the growth plate after playing in an infant stationary activity center called an Exersaucer. It is possible that the twisting motion provided by the Exersaucer (Evenflo, Picqua, OH) might be consistent with the generation of forces necessary to cause these fractures.
