Sacral Stress Fracture following the Bone Union of Lumbar Spondylolysis

<div>Magnetic resonance images of the sacrum one year after conservative treatment. (a) Coronal plane on a short TI inversion recovery (STIR) image. (b) Axial plane at the S2 level on a STIR image. Coronal plane (a) and axial plane at the S2 level (b) on a STIR image show no abnormal signal intensity. These radiological findings indicated bone union of the sacral stress fracture.</div>
