Progressive Scoliosis and Multiple Epiphyseal Dysplasia


The patient is a 16-year-old female with multiple ephysial dysplasia who was diagnosed with scoliosis at age 12. No treatment was recommended at that time. She presents with progressive back pain, left hip pain, and worsening posture.


  • Motor and sensory exams were normal.
  • She had no pathologic reflexes and no leg-leg discrepancy.
  • She has short stature and a slightly waddling gait.
  • There was an obvious left lumbar prominence on bending test.
  • No shoulder asymmetry was appreciated.

Pre-Treatment Imaging

Standing scoliosis series demonstrated a right main thoracic curve of 28-degrees that corrected to 22 on bending films, and left lumbar curve measuring 62-degrees with minimal correction (Figure 1).

  • Thoracic kyphosis: 15-degrees (Figure 2)
  • Lumbar lordosis: 44-degrees
  • Pelvic incidence: 45-degrees
  • Risser score: 5

MRI lumbar spine shows multilevel lumbar stenosis, worst at L4-L5 (Figures 3, 4).

Suggest Treatment

Indicate how you would treat this patient by completing the following brief survey. Your response will be added to our survey results below.

Selected Treatment

Correction of the lumbar curve with L4-L5 decompression and T10-Ilium fixation.

Surgeon's Comments
The patient has progressive scoliosis, back and left hip pain. It was unclear whether the pain pattern was radicular but, given spinal stenosis on MRI, a decompression was planned.

X-rays showed a rather rigid fractional curve and this, along with the need for decompression, influenced the decision to anchor distally to the ilium.

Intraoperatively, there was arthrosis of the facet joints and the curve was not flexible. Multilevel facetectomies and Ponte osteotomies were performed to facilitate correction.

Post-Surgical Imaging

post-operative scoliosis surgery standing anterior and lateral x-raysFigures 5A, 5B. Post-operative standing anterior (5A) and lateral (5B) x-rays. Lumbar scoliotic curve reduced from 62-degrees to 23-degrees.


The patient did well immediately post-operatively with improvement in mechanical back and hip pain. The lumbar curve was corrected from 62- to 23-degrees with improvement in truncal shift as well.

Peer Discussion

Dr. Baaj presents a very unique patient with the combination of multiple epiphyseal dysplasia, scoliosis and lumbar stenosis. The patient clearly had an operative lumbar curve measuring 62-degrees, with a compensatory thoracic curve.

The decision of whether or not to include the thoracic curve involves factors such as coronal magnitude, sagittal kyphosis and axial rotation. Since all appeared favorable, Dr. Baaj's decision not to include it in the fusion appears sound.

Although concomitant lumbar decompression with deformity correction is not common in the pediatric population, the marked stenosis mandated a combined procedure. The post-operative x-rays demonstrate excellent overall balance and curve correction.
