Background: Epiphyseal detachment fractures of the distal end of the femur are relatively common in patients with spinabifida, but they most often go unnoticed due to sensory disturbances and/or minimal displacement of the fractures in this type of patient. These patients present with a hot tumefaction of the knee often with general inflammatory signs, but without pain or notion of trauma. We report a case of epiphyseal detachment fracture of the distal end of the femur in a 06-year-old child with myelomeningocele. Distal femoral physical injuries are relatively common in patients suffering from spina bifida; but often go unnoticed due to lack of sensitivity and/or the minimally displacement of fractures in this case of patients. These patients present with warmth swollen knee with often inflammatory signs, with no known history of trauma or pain. We report the case of physical injury of distal femur in a 6-year-old child with myelomeningocele.
