An 84-year-old woman with Sjogren's syndrome injured her T12 vertebral fracture after a fall and was conservatively treated using thoracolumbosacral orthosis (Fig. 1). Magnetic resonance imaging (MRI) revealed an old vertebral fracture with an effusion at T12, with no spinal cord compression (Fig. 1).
CT (left) in the supine position showing no compression of the spinal cord; however, flexion dynamic CT (right) reveals protrusion of occult bony fragment and spinal cord compression.

A computed tomography (CT) myelogram showed a wide canal in the supine position; however, a dynamic CT in the flexion position revealed spinal cord compression with a mobile bony fragment (Fig. 2).
Postoperative X-ray and CT revealed rigid fixation and complete fusion of the bony fragment within the vertebra one year later.

She underwent laminectomy, vertebroplasty with hydroxyapatite block, and posterior spinal fixation from T10 to L2 (Fig. 3). CT revealed a complete fusion of the bony fragment within the vertebra one year later (Fig. 3).
