RISFunctional Validation of a Complex Loading Whole Spinal Segment Bioreactor Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Intervertebral disk (IVD) degeneration is a prevalent health problem that is highly linked to back pain. To understand the disease and tissue response to therapies, ex vivo whole IVD organ culture systems have recently ...
The Interior Contact-Aided Rolling Element
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work introduces an interior contact-aided rolling element (I-CORE) compliant mechanism that draws upon the concepts used for the contact-aided rolling element, cross-axis flexural pivot, and pre-curved flexible beam. ...
Mechanical and in Vitro Testing of a Biomechanically Fidelic, Compliant Mechanism Based, Motion-Preserving Lumbar Interbody Device
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common approach to resolving discogenic low back pain involves replacing one or more degenerated spinal discs with a total disc replacement device. However, existing solutions for intervertebral disc replacement are ...
Changes in Vertebral Strain Energy Correlate With Increased Presence of Schmorl's Nodes in Multi Level Lumbar Disk Degeneration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Patients with skippedlevel disk degeneration (SLDD) were recently reported as having a higher prevalence of Schmorl's nodes than patients with contiguous multilevel disk degeneration (CMDD). Fourteen versions of a nonlinear ...
Leveraging Compliance to Design a Minimally Invasive, Expandable Interbody Cage Capable of Customized Anatomical Fit for Spinal Fusion Surgery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As spinal fusion surgery continues to transition to less invasive techniques, there remains an unmet need for ever smaller and more complex interbody cages to meet the unique needs of this difficult surgery. This work ...
