Objectives: This was an analytic retrospective observational study. The aims were (1) to
validate patient-specific templating process by comparing postoperative range of motion …

BACKGROUND CONTEXT: Total disc replacement is a novel approach for dynamically
stabilizing a painful intervertebral segment. While this approach is gaining popularity, and …

Background The current generation of total disc replacements achieves excellent short-and
medium-term results by focusing on restoring the quantity of motion. Recent studies indicate …

Study Design. A validated nonlinear three-dimensional finite element (FE) model of a single
lumbar motion segment (L3-L4) was used to evaluate the effects of total disc replacement …

Objective The purpose of this study was to analyze the biomechanical effects of three
different constrained types of an artificial disc on the implanted and adjacent segments in the …

BACKGROUND CONTEXT: A recently published FDA clinical trial (McAfee et al. 2005)
noted that nearly 90–95% of all Charité disc prostheses were placed between 2 mm …

Lumbar total disc replacement (TDR) is an evolving technique that has the potential to
replace arthrodesis as the gold standard surgical treatment of degenerative disc disease …

The total disc replacement (TDR) devices are gaining popularity because of their capability
of allowing joint motion at the index level. Studies have shown that motion preservation can …

Study Design. A three-dimensional, nonlinear finite element analysis was performed to
predict the in situ contact interaction of prosthesis components of the Prodisc-L in a …

Study Design Combining in vitro tests and finite element analysis to provide a more
complete picture of the role that a disc prosthesis implant would play in the biomechanics of …
