Título del libro: Asme International Mechanical Engineering Congress And Exposition, Proceedings (imece) Título del capítulo: CURRENT SITUATION OF DESIGN CRITERIA FOR INTERVERTEBRAL DISC PROSTHESIS
This paper presents the literature review on the design criteria for
intervertebral disc prosthesis. The design criteria relate to the design
features that intervertebral prosthesis must accomplish (i.e. fixation
to bones, spine mobility, energy absorption and etcetera). The need to
improve the performance has led to changes in the features which reflect
in the current design criteria.
Currently, the disc prosthesis technology is experiencing a generational
change. The first generation was thoroughly studied while the second
generation is in the clinical tests stage. During the time the first
generation prostheses were applied in patients there was not a clear
trend in the clinical results which produced a lack of trust and
reliability in the performance of the disc prosthesis. The changes in
the design features of one generation compared to the next generation
are based in the deepening in the knowledge of the problem and the
results obtained with the first generation prostheses.
Some design criteria were identified for the first generation. These
criteria were not completely characterized since there was not enough
information to be used by the designer. This lack of characterization of
most design criteria produced many different versions without a clear
focus which help to define the basic design features of disc prostheses.
This document presents the necessary information to thoroughly
characterize the design criteria outlining the missing information for
the design criteria found. An analysis is done of the design criteria in
the second generation of prosthesis.
Finally if the information contained in the design criteria is enough,
the clinical results would be better focused to achieve a more
repeatable, reproducible and reliable process for a total disc
intervertebral prosthesis replacement as now is considered the vertebral
fusion, this is a gold standard.
