A pipeline to morph finite element models of the lumbar spine for generation of customised spinal cages.

ABSTRACT:

Background

Lumbar interbody fusion with spinal cages is an established treatment for degenerative disc disease, however, generic cages comprising standardised shapes and sizes still encounter complications such as cage migration and subsidence. Incorporating biomechanical analysis and implant customisation for pre-operative planning provides the possibility to optimise cage positioning and its 3D geometry, such that cage loading is optimised to reduce the chance of post-operative complications. However, current customisation processes involve considerable resources to develop personalised finite element models for evaluating bespoke cage designs. Therefore, this study aimed to build an automated pipeline to generate personalised lumbar FE model with a customised spinal cage.
