STUDY DESIGN A paired comparison was done of the bending flexibility and compression strength of tricortical bone graft and titanium fiber mesh implants in a human cadaver model of posterior lumbar interbody fusion. OBJECTIVES To test the hypothesis that a titanium fiber mesh implant and a tricortical bone graft provide adequate and equal mechanical(More)
STUDY DESIGN A rabbit model was used to compare clinical outcome, radiographic changes, and biomechanical flexibility after cervical laminectomy and open-door laminoplasty. OBJECTIVE This study tested the hypothesis that radiographic changes and biomechanical flexibility could explain the differences in clinical outcome after cervical laminectomy and(More)
This study determined the ability of an upper extremity Tarlov scale, a lower extremity Tarlov scale, and the Durham scale to predict the development of myelopathy and the likelihood of survival in a rabbit model of surgical treatments for cervical spondylotic myelopathy. Forty-eight rabbits were evaluated using the scales after cervical spinal surgery.(More)
For use as a graft in spine fusion, a titanium fiber metal implant (TFMI) from a woven pure titanium wire 250 micron in diameter was studied for its mechanical properties and biological fixation. Compression testing showed that the failure stress and modulus of elasticity of our implant closely resembled those previously reported fiber metals. It was,(More)
