A new spine surgery simulator (S3) aids in planning scoliosis correction strategies. This tool accurately predicts surgical outcomes, offering clinical relevance for preoperative planning of spinal instrumentation.

Area of Science:

  • Spine biomechanics
  • Surgical simulation technology
  • Orthopedic surgery

Background:

  • Current clinical tools lack user-friendliness, reliability, and refinement for preoperative planning of scoliosis correction.
  • No adequate tool exists for predicting spinal correction based on patient characteristics and instrumentation variables.

Purpose of the Study:

  • To develop and evaluate a surgeon-friendly spine surgery simulator (S3).
  • To predict scoliosis correction efficacy based on patient specifics and instrumentation choices.

Main Methods:

  • Developed a kinetic model with flexible mechanisms for patient-specific spine geometry and flexibility.
  • Simulated individual correction substeps using an instrumentation system.
  • Created a surgeon-friendly interface for interactive specification of instrumentation, maneuvers, and results display.

Main Results:

  • Simulations for 10 scoliotic cases showed good agreement with postoperative results (Cobb angle differences: 3.5–4.6° frontal, 3.6–4.7° sagittal).
  • Implant-vertebra link forces were generally below pull-out values, with higher forces at instrumentation extremities.

Conclusions:

  • The spine surgery simulator (S3) demonstrates technical feasibility and clinical relevance.
  • S3 can assist in preoperative planning of instrumentation strategies for correcting scoliotic deformities.
