Biomechanical evaluation of a biomimetic spinal construct
BACKGROUND Laboratory spinal biomechanical tests using human cadaveric or animal spines have limitations in terms of disease transmission, high sample variability, decay and fatigue during extended testing protocols. Therefore, a synthetic biomimetic spine model may be an acceptable substitute. The goal of current study is to evaluate the properties of a synthetic biomimetic spine model; also t...
متن کاملBiomechanical properties of anterior thoracolumbar multisegmental fixation: an analysis of construct stiffness and screw-rod strain.
STUDY DESIGN Three types of anterior thoracolumbar multisegmental fixation were biomechanically compared in construct stiffness and rod-screw strain. OBJECTIVES To investigate the effects of rod diameter and rod number on construct stiffness and rod-screw strain in anterior thoracolumbar multisegmental instrumentation. SUMMARY OF BACKGROUND DATA No studies have been undertaken to investigat...
متن کاملMolecular extensibility of mini-dystrophins and a dystrophin rod construct.
Muscular dystrophies arise with various mutations in dystrophin, implicating this protein in force transmission in normal muscle. With 24 three-helix, spectrin repeats interspersed with proline-rich hinges, dystrophin's large size is an impediment to gene therapy, prompting the construction of mini-dystrophins. Results thus far in dystrophic mice suggest that at least one hinge between repeats ...
متن کاملBeyond family-friendly: The construct and measurement of singles-friendly work culture
Although research has examined work-family issues and organizational support for employees’ family responsibilities, few studies have explored the work-life issues of single employees without children. The current study examines single employees’ perceptions of how their organizations support their work-life balance in comparison to employees with families. A multi-dimensional scale is develope...
متن کاملThe effects of rod contouring on spinal construct fatigue strength.
STUDY DESIGN In vitro fatigue loading using a corpectomy model outfitted with posterior pedicle screw instrumentation. OBJECTIVE The purpose of this study was to detect differences in fatigue resistance of titanium and stainless steel spinal constructs that use rods contoured using a French Bender, and to compare differences in fatigue resistance of contoured and straight titanium rods. SUM...
