DOWNLOAD EBOOKTo conclude, this study highlighted that cervical disc replacement with both the Bryan and Prestige LP discs not only preserved the motion at the operated level, but also maintained the normal motion at the adjacent levels. Under hybrid loading, the motion pattern of the spine with a TDR was closer to the intact motion pattern, as compared to the degenerative or fusion models. Also, in the presence of a pre-existing fusion, this study shows that an adjacent segment disc replacement is preferable to a second fusion.

DOWNLOAD EBOOKHuman intervertebral disc replacement is quickly becoming a superior substitute for cervical disc fusion as a surgical treatment for degenerative disc disease. The current disc implants share similar materials and show significant improvements over past designs. Scientific studies continue to evaluate the results of the implants compared to fusion, with the primary focus placed on the preservation of normal spine biomechanics with the articulating abilities of the implant versus absence of motion with fusion. This thesis investigated the biomechanical effects on the spine with eccentricity of the implant. More specifically, implantation at a location that is laterally offset from the midsagital axis, thus yielding misalignment to the patient's left or right from the geometric vertical axis. This study concentrates on the three main joints in the cervical spine and the load distribution on them due to a static axial loading case only. Three separate evaluations were used to compare results. A mechanical testing apparatus that simulates eccentric implantation was designed, built, and tested. Numerical and mathematical models of this apparatus completed the trio of evaluations. The results showed a characteristic that is linear. That is, minor offsets in the order of millimeters demonstrate significant increases in static loads on the facet furthest from the implant. A consideration of these results and research suggests that this could be the cause of long-term facet degeneration. The conclusion of this thesis suggests future research is needed to further understand this phenomenon, improve the surgical technique, or improve the implant, all in order to either better understand the biomechanical sacrifices with eccentric implantation or eliminate it all together.

Cervical Spine Biomechanics Following Treatments for Degenerative Disc Disease

DOWNLOAD EBOOKAnterior cervical disc fusion (ACDF) has been a treatment for degenerative disc disease for the last 50 years. ACDF, with a success rate of 95 percent, has been established as the primary method for treating disc disease. However, the fusion approach eliminates motion, which is philosophically different from technologies developed to treat other articulating joints. Subsequently, ACDF is believed to accelerate degeneration in spinal motion segments adjacent to the treated level and lead to cascading failures of the nearby discs. The desire to eliminate such cascading failures has prompted the development of an articulating cervical disc implant (ACDI). The objective of this research was to compare the mechanical behavior of a cervical spine specimen following ACDI with the mechanical behavior of the same specimen following ACDF. A mechanical testing device was developed to induce a controlled, pure moment loading scheme and to facilitate near physiological flexion-extension motion. The measures used to quantify the comparison were global kinematics, segmental kinematics, and intradiscal pressures. This study concluded the performance of the ACDI was at least equivalent to ACDF. Furthermore, this study suggested the ACDI promoted more energy absorption within the cervical spine and transferred less stress to adjacent discs at higher loads than the ACDF, but more tests are required to increase our confidence in this interesting possibility.
