Biomechanical Comparison of Lumbar Disc Replacements
… available treatments: disc replacement with ProDisc-L, disc replacement with Maverick, and a pedicle screw fixation. It was hypothesized that structural designs differences of ProDisc-L and Maverick could be distinguished in both motion and loading patterns. It was also hypothesized that …

Explicit Finite Element Modeling of the Human Lumbar Spine
… of these disc replacement devices like the ProDisc-L (Synthes Spine, West Chester, PA). Placement of the spherical center of the device as close as possible to the anatomical axis of rotation of the segment is essential in achieving optimal performance.</p> <p>Accordingly, an explicit FE …

Anatomy, Implant Selection and Placement Influence Spine Mechanics Associated with Total Disc Replacement
… cohort of twenty two patients implanted with the ProDisc-L device and suggested changes to total disc replacement size selection and alignment to improve ROM. Predicted ROM was 11.8% different to actual ROM. Improvements in ROM could have been achieved in over 85% of the cases had the proposed …

Robotic Simulation of Disc Arthroplasty Surgery: Influence of Surgical Placement on Motion Segment Dynamics
… of a simulated ball and socket TDR, like the ProDisc-L lumbar disc prosthesis.</p> <p>Six human cadaveric lumbar MSUs, L4-L5, were tested in flexion/extension using the Spine Robot to an end load limit of 8Nm. A fixed axis protocol was used to impose a pure rotation about a desired anatomical …

A Passive Pure Moment Protocol for Testing Spine Segments: Development and Application
… specimens were implanted with a constrained ProDisc-L implant (Synthes Inc., West Chester, PA) by a spine surgeon under fluoroscopy. All pure moment testing was repeated on the implanted specimen.</p> <p> Throughout testing, the specimens underwent an average off-axis force of 1.51N. With an …
