The Development And Application Of A Custom Robotic Biomechanical Testing Platform Employing Real-Time Load-Control To Compare Spinal Biomechanical Testing Protocols: Pure Moment, Ideal Follower Load, And A Novel Trunk Weight Protocol, Charles Ramsey Bennett May 2013

The Development And Application Of A Custom Robotic Biomechanical Testing Platform Employing Real-Time Load-Control To Compare Spinal Biomechanical Testing Protocols: Pure Moment, Ideal Follower Load, And A Novel Trunk Weight Protocol, Charles Ramsey Bennett

Theses and Dissertations (ETD)

The human lumbar spine has been the subject of biomechanical study for many decades owing to the numerous medical cases resulting in the development of various corrective surgical procedures and medical devices intended to relieve patient discomfort. Spinal biomechanics is a broad field containing but not limited to the in vitro study of cadaveric tissue utilizing testing platforms used to apply motion- or load-profiles to tissue in the investigation of the various kinetic or kinematic responses, respectively. The particular arena field of this research concerns the field of robotics as it applies to testing platforms and how they are applied …


Biomechanical Comparison Of Traditional Laminectomy And Minimally‑Invasive Facetectomies, Karen Sedacki May 2011

Biomechanical Comparison Of Traditional Laminectomy And Minimally‑Invasive Facetectomies, Karen Sedacki

Theses and Dissertations (ETD)

The facet joints of the lumbar spine are one of the sources of low‑back pain that affects a great portion of the population. Minimally‑invasive (MI) procedures have been becoming more popular in the surgical decompression of the spine because they offer shorter recovery time and involve removal of smaller amounts of important structures. With these features, it is believed that MI procedures lead to less clinical instability, and the functionality of the segment is maintained. Another important factor is how the facet angle in the lumbar segments affects the biomechanical instability. In spite of all this interest in MI procedures, …
