Summary

Neuromuscular scoliosis are caused by a disorder of the brain, spinal cord or muscular system and often progressive at early age. Conservative treatment is not sufficient to maintain trunk and pelvic balance, and surgical treatment is frequently required. Early definitive spine fusion has the disadvantage of cessation of trunk growth with concomitant effects on lung development. Growth preserving spine surgeries are increasingly used but with high complication rates.

The orthopaedic team at Necker Hospital Enfants maladies, Paris, France has developed an innovative fusionless surgery based on a bipolar spine construct, performed by a minimally invasive approach. The first 100 patients operated on with this technique had an average follow-up of 6.5 years. No arthrodesis, initially planned in adolescence, was necessary thanks to the stability of the correction of the deformities even after skeletal maturation.

The main objective of the study was to analyze the progressive spinal stiffening, using muscle and disc elastography, in neuromuscular patients instrumented with this bipolar construct.

Conditions

  • Neuromuscular Scoliosis

Interventions

OTHER

Ultrasound elastography (USE)

Visualization of the vertebral disc and the para-vertebral muscles. Intra and inter observer reproducibility analysis carried out for each of the measurements made, by two operators. Patients with instrumented neuromuscular scoliosis: 5 elastographies : preoperatively, then during the usual follow-up consultations with the surgeon every 6 months for 2 years. Patients with neuromuscular pathologies without instrumented scoliosis: 4 elastographies during the usual follow-up consultations with the surgeon every 6 months for 2 years. Healthy control patients without neuromuscular pathology or scoliosis : 1 elastography during an usual consultation.
