Biomechanical Testing of Two-Level Cervical Disc Arthroplasty
… studies comparing two-level cervical disc arthroplasty with two-level fusion were completed using an established cadaveric cervical spine model. Three conditions were tested: non-instrumented, instrumented with two-level fusion (C5-C6 and C6-C7), and instrumented with two-level …

Robotic Simulation of Disc Arthroplasty Surgery: Influence of Surgical Placement on Motion Segment Dynamics
<p>A variety of total disc replacement (TDR) designs exist for the treatment of disc pathologies. A key design parameter for a constrained ball and socket device is the location of the fixed center of rotation (COR). A previous study demonstrated that intact motion segment unit (MSU) mechanics and …

Multi-objective design optimization of a mobile-bearing total disc arthroplasty considering spinal kinematics, facet joint loads, and metal-on-polyethylene contact mechanics
<p>Total disc arthroplasty (TDA) is a motion-preserving surgical technique used to treat spinal disorders, when more conservative medical therapies fail. Unfortunately, a high incidence of revision surgery exists due to postoperative complications including abnormal kinematics, facet joint …

A Virtual Model of the Human Cervical Spine for Physics-based Simulation and Applications
… stiffness curves, and animations of the disc and facet forces. This model was used to evaluate different mounting configurations for axial rotation testing and to identify a set of end constraint conditions that produced physiologic responses during axial rotational loading. This model …
