Surgical Orthopedics in a Spondylometaphyseal Dysplastic Patient

Spondylometaphyseal dysplasia (SMD) is a rare disease characterized by vertebral and metaphyseal abnormalities. The treatment of SMD spinal deformities remains a challenge for spinal surgeons. The purpose of this study is to demonstrate the feasibility and effectiveness of vertebral column resection of SMD by thoracolumbar kyphosis and scoliosis.

A 23-year-old man with SMD was referred to us with multivertebral anomalies and scoliosis, and a rigid curved thoracolumbar kyphosis in T11-12. The patient had fixed thoracolumbar kyphosis and scoliosis with neurologic symptoms. The morphology of vertebra was measured and calculated based on radiologic data. A 3-dimensional printing was made to help the spinal orthopedics. The anterior fusion was made with cages reconstruction and posterolateral fusion with screw fixation.

The spinal axes were corrected with obvious and satisfying realignment effects. The neurologic symptoms disappeared after surgery. The 1-year follow-up period was uneventful. Surgical treatment for SMD multiaxial spine malformation is feasible. Posterior column resection with segmental pedicle screw fixation and complementary fusion provides obvious curative effects for adult patients with neurologic complications.
