Abstract

Background Birth-related femur fractures are rare. They have been reported following difficult delivery and are commonly diagnosed immediately after birth or on the following day. However, some birth-related femur fractures are diagnosed several days after birth. Mechanisms underlying the development of delayed femur fracture are incompletely understood.

Case We report the case of a girl diagnosed with a left spiral femur fracture with associated edema and hypoesthesia on postpartum day 9. A nondisplacement femur fracture was identified on plain radiography at birth after cesarean section; however, it was undiagnosed due to the lack of symptoms. She was treated with plaster cast fixation; the physical examination at age 1 was normal. Herein, the diagnosis of birth-related femur fracture according to plain radiography findings suggests that the symptoms related to birth trauma develop several days after birth.

Conclusion Birth-related fracture should be considered in all neonatal femur fracture cases and in patients with no symptoms at birth. Neonates delivered in the breech presentation by cesarean section should be carefully monitored after birth. The findings of the present case further our understanding of the pathogenic mechanisms underlying delayed diagnosis of birth-related femur fracture.
