Summary

Developing finite element models for adolescent scoliosis surgery planning is crucial. Simulating spinal flexibility revealed that costo-vertebral joint properties alone do not fully predict outcomes, requiring further biomechanical analysis.

Area of Science:

  • Biomechanical Engineering
  • Orthopedic Surgery
  • Medical Imaging

Background:

  • Adolescent scoliosis surgery has high complication rates, necessitating improved surgical planning.
  • Finite element models (FEM) offer a promising approach for simulating spinal deformities.
  • Patient-specific models are essential for accurate surgical planning and outcome prediction.

Purpose of the Study:

  • To develop finite element models of the thoracolumbar spine for adolescent scoliosis deformity surgery simulation.
  • To investigate the influence of patient-specific tissue properties on spinal flexibility assessments.
  • To improve the accuracy of pre-operative surgical planning tools for scoliosis.

Main Methods:

  • Developed patient-specific FEMs of the thoracolumbar spine using low-dose CT scans.

  • Simulated the fulcrum bending radiograph, a pre-operative spinal flexibility assessment.
  • Adjusted costo-vertebral joint (CVJt) tissue properties to match clinical data in ten patients.

    • Main Results:

    • Achieved acceptable agreement between simulated and clinical spinal flexibility in two out of six cases by altering CVJt stiffness.
    • Demonstrated that spinal flexibility in the fulcrum bending test is not solely dependent on isolated soft tissue structures.
    • Highlighted the need for more detailed biomechanical characterization of the fulcrum bending test.

    Conclusions:

    • Current finite element models require refinement for accurate prediction of spinal flexibility in adolescent scoliosis.
    • Patient-specific soft tissue properties, particularly in the CVJt, play a complex role in spinal biomechanics.
    • Further research into the biomechanical behavior of the spine during flexibility tests is needed to enhance surgical planning tools.
