Fatigue Fractures of the Sacrum on Children: Case Report

Fatigue fractures of the sacrum in children are very rare and the diagnosis is often delayed or incorrect. The authors report the case of a healthy 10-year-old child, active soccer player, presented with a ten days' history of insidious onset of his mechanical low back pain, without any history of trauma. Plain radiography of the lumbosacral spine and pelvis was also normal. The MRI showed images which were consistent with a stress fracture. It is of paramount importance to make a prompt and accurate diagnosis of a fatigue fracture so as to avoid unnecessary invasive investigations.
