BACKGROUND: The influence of lumbar endplate morphology on the clinical and
radiographic outcomes of lumbar disc arthroplasty has not been evaluated to the best of our …

Study Design This study was a prospective study with a minimum patient follow-up of 2
years. Objective The purpose of this study was to evaluate the clinical usefulness of a …

BACKGROUND CONTEXT: There have been several studies attempting to identify factors
related to clinical outcome following total disc replacement (TDR). These include individual …

Purpose Clinical observations suggest that endplate shape and size are related to
complications of disc arthroplasty surgery. Yet, the morphology of the vertebral endplate has …

Abstract Summary of background data The sagittal profile of lumbar endplates is discrepant
from current simplified disc replacement and fusion device design. Endplate concavity is …

Objective To determine whether angular mismatch between the vertebral endplate and
prosthetic endplate during lumbar total disc replacement (L-TDR) affects the radiological …

Lumbar disc prostheses have been used increasingly in recent years. The successful design
of lumbar disc prostheses depends on accurate morphometric parameters. However, the …

Background Information on the three-dimensional (3D) shape of vertebral end plates is
lacking. Previous studies have analyzed two-dimensional shape; however, 3D data are …

Purpose Variability of the human lower lumbar geometry is related to complications of disc
arthroplasty surgery. Accurate morphometric descriptions are essential for the design of …

Study Design. Retrospective image-based analysis. Objective. To measure endplate three-
dimensional (3D) geometry, endplate changes in vivo and to investigate correlations …
