Biomechanics of the posterior lumbar articulating elements

Autor: Andrew Dooris, Hassan Serhan, Michael N. Tzermiadianos, Gus Varnavas, Avinash Patwadhan

Publikováno v: Neurosurgical Focus. 22:1-6

✓The clinical success of lumbar spinal fusion varies considerably, depending on techniques and indications. Although spinal fusion generally helps to eliminate certain types of pain, it may also decrease function by limiting patient mobility. Furth

The fundamentals of biotribology and its application to spine arthroplasty

Autor: Philippe E. Paré, Andrew Dooris, Megan L. Harper

Publikováno v: SAS Journal

The biological effect of wear of articulating surfaces is a continued concern with large joint replacements and, likewise, of interest for total disc replacements. There are a number of important biotribological testing parameters that can greatly af

Publikováno v: Journal of Neurosurgery: Spine. 93:252-258

Object. The goal of this study was to evaluate the comparative efficacy of three commonly used anterior thoracolumbar implants: the anterior thoracolumbar locking plate (ATLP), the smooth-rod Kaneda (SRK), and the Z-plate. Methods. In vitro testing w

Determining Edge of Failure of a Spinal Wear Bearing

Autor: Leigh W. Potter, Paul J. Ares, Andrew Dooris

Publikováno v: ASME 2011 6th Frontiers in Biomedical Devices Conference and Exhibition.

Mechanical test samples are often characterized using time-varying loads, either through slow monotonic changes in quasi-static testing, or through more rapid cyclic changes in dynamic testing. Spinal implant static and fatigue strengths are typicall

Test protocols for evaluation of spinal implants

Autor: Hassan Serhan, Vijay K. Goel, Avinash G. Patwardhan, Andrew Dooris, Manohar M. Panjabi

Publikováno v: The Journal of bone and joint surgery. American volume. 88

Prior to implantation, medical devices are subjected to rigorous testing to ensure safety and efficacy. A full battery of testing protocols for implantable spinal devices may include many steps. Testing for biocompatibility is a necessary first step.

Initial Wear Characterization of a Spinal Artificial Disc

Autor: S. Daniel Kwak, Paul J. Ares, Andrew Dooris, Hassan Serhan, Stefan M. Gabriel

Publikováno v: World Tribology Congress III, Volume 2.

Local reactions to wear debris generated by hip and knee replacement devices have been shown to lead to failure of some devices via osteolysis and component loosening. This has not been shown to be a clinical issue with the most widely used spinal ar
