Spinal surgery in spinal muscular atrophy.

Y H Daher, J E Lonstein, R B Winter

    Journal of Pediatric Orthopedics
    |July 1, 1985
    PubMed
    Summary

    Surgical treatment for spinal muscular atrophy (SMA) involving spinal fusion achieved significant curve correction. Posterior spinal fusion with Harrington or Luque instrumentation is recommended for optimal outcomes in SMA patients.

    Area of Science:

    • Orthopedics
    • Neuromuscular Disorders
    • Spinal Surgery

    Background:

    • Spinal muscular atrophy (SMA) often leads to severe scoliosis.
    • Surgical intervention is crucial for managing spinal deformities in SMA patients.
    • Evaluating surgical techniques for spinal fusion in SMA is essential.

    Purpose of the Study:

    • To review surgical outcomes for spinal muscular atrophy patients.
    • To assess the effectiveness of different spinal fusion techniques.
    • To identify optimal surgical timing and methods for SMA-related scoliosis.

    Main Methods:

    • Retrospective review of 15 patients with SMA undergoing spinal surgery.
    • Analysis of curve patterns (thoracic, thoracolumbar, double).
    • Evaluation of posterior spinal fusion with Harrington and Luque instrumentation, including segmental wiring.

    Main Results:

    • Average follow-up was 31 months.
    • Average curve correction was 48%, with 63% correction when pelvic obliquity was addressed.
    • Posterior spinal fusion with Harrington instrumentation was performed in 11 patients.

    Conclusions:

    • Surgery is most effective when spinal curves are between 50-60 degrees.
    • Luque sublaminar wiring with Harrington instrumentation or Luque rods without external support is the preferred surgical approach.
    • This approach offers favorable outcomes for spinal deformity in spinal muscular atrophy.
