A patient specific total disc replacement to treat degenerative disc disease
… arising from degeneration of the intervertebral discs (IVD). When conservative treatments fail, surgical replacement with an artificial total disc replacement (TDR) is often required. However, despite decades of refinement, current TDRs are unable to fully replicate the complex mechanical …

Anatomy, Implant Selection and Placement Influence Spine Mechanics Associated with Total Disc Replacement
<p>Through aging and injury, the intervertebral disc of the lumbar spine can undergo degeneration, leading to collapse of the vertebrae and low back pain, a symptom that affects half the adult population in any given year. In an effort to reduce low back pain, total disc replacement treatment …

An Evaluation of Presurgical Psychological Screening as a Predictor of Outcome for Total Disc Replacement
… the response to treatment by patients undergoing Total Disc Replacement (TDR). Subjects participated in a psychological screening prior to surgery and were given a prognosis that was then used to determine whether they were fit to proceed with surgery. All participants in this study had a …

Explicit Finite Element Modeling of the Human Lumbar Spine
… with normal spine function and degenerative disc disease (DDD), as well as the impact of fusion and total disc replacement (TDR). Although experimental data from fully intact specimens can be used for model calibration and validation, the contributions from the individual structures (disc, …

An In Vivo histological, and In Vitro biomechanical study of nucleus replacement with a novel polymeric hydrogel
Nucleus replacement has recently come into favor as a possible treatment for Degenerative Disc Disease. Replacing degenerative nucleus tissue with a synthetic material that mimics healthy nucleus tissue may restore normal function and biomechanics to the disc and delay or obviate the need for more …

Polymer Composite Spinal Disc Implants
… similar to that of the natural intervertebral disc, as well as find preliminary results for vertebral endplate connection and nucleus pulposus internal pressure, for the correction of disc degeneration in the spine. The three-part composite samples needed to demonstrate good shock absorption …

A Passive Pure Moment Protocol for Testing Spine Segments: Development and Application
… specimen and those implanted with a constrained total disc replacement (TDR) device.</p> <p> Six human lumbar single-level motion segment units (MSUs) at the L4-L5 level were dissected and potted. The average age of the spines was 47 ± 11.4 years. The robot was programmed to rotate the specimen …

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 …

Simulated Automobile and Rotary-Wing Aircraft Impacts: Dynamic Neck Response after Surgical Treatment for Cervical Spondylosis
… arthrodesis achieved through anterior cervical discectomy and fusion (ACDF). A relatively newer treatment is arthroplasty with a cervical total disc replacement (CTDR), a motion-sparing procedure designed to maintain adjacent-level loading. While literature exists comparing the effects of …
