Abstract

Surgical techniques for correcting scoliotic deformities are continuously evolving, and computer modeling has become a valuable tool to support surgeons in testing and optimizing spinal instrumentation and corrective strategies. This study introduces a novel hybrid model capable of simultaneously computing rigid-body dynamics during surgical correction and estimating mechanical stresses within def…
