Effect of an artificial disc on lumbar spine biomechanics: a probabilistic finite element study

Effect of Artificial Disc Position on Spine Biomechanics in the Cervical Spine: A Finite Element Study

INTRODUCTION Total disc replacement(TDR) has been suggested for surgical method to treat degenerative disc disease of the cervical spine because it decompresses nerves and preserves motion segments. The short-term outcomes of the TDR of cervical spine has been well reported to treat degenerative disc diseases as a motion preservation technique in spite of some clinical controversies such as imp...

Biomechanical study of lumbar spine with artificial disc replacement using three-dimensional finite element method

Biomechanical analyses on lumbar spine under compressive load and flexion torque were performed using a nonlinear three-dimensional finite element method to evaluate the stability of artificial disc replacement. We prepared a validated intact lumbar L4-L5 motion segment and artificial disc inserted motion segment by replacing intact disc with the artificial disc which is being developed. Effect...

Implications of Artificial Disc Design on the Intersegmental Biomechanics of the Lumbar Spine

INTRODUCTION: Design of total disc replacement (TDR) prosthesis plays an important role in the long-term clinical performance of these implants. Prodisc-L (Spine Solutions, Inc. Synthes, Paoli, PA, USA), a semi-constrained TDR system, has a ball-and-socket based design; whereas SB Charité III (DePuy Spine, Inc, Raynham, MA, USA) has a theoretically unconstrained articulation which allows the mo...
