Cervical Disc is one of the more vitally important and
mechanically astounding skeletal structures, which allows a vast range of
motion between the vertebrae in the neck, all the while absorbing large amounts
of compression from regular movement. This paper presents a comprehensive
review and critical comparison of most recent design and optimization methods
of cervical disc. In order to solve an optimization problem of an artificial
disc, various assessment parameters such as load, material and it is properties
and geometry are explained and summarized. The selection of some of these
parameters is essentially to obtain an optimal combination for the artificial
disc. Based on the review, it is observed that the use of experimental results
and validate data in the optimization problem improve the results compared to
the use of analytical solution only, but unfortunately a few author used
optimization algorithms, as it is mention in tables (6 and 9). Most of the
papers for CD system are carried out based on finite element analysis including
selection of type of element, number of element and mechanical properties.
However, as a natural geometry, ROM and natural material are considering as the
most important constrains, there is a need for even much accurate and highly
advanced optimization for selecting of artificial disc replacement. Therefore,
to solve the complexity of this mechanism a hybrid algorithms and more
optimization algorithms with robust controller need to be apply for CD
problems. Moreover, software computer tools are also used widely for designing
of artificial CD. However, using modern technique, material and methods will
provide more accurate optimization results than the regular software and the
old tools as they have the ability to solve multi-objective optimization
problems. This paper reviews the main basic research methods and their
corresponding applications in CD, aiming to let more experts know the current
research status and also provide some guidance for relevant researches. Based
on previous studies FE method is the most appropriate to follow. Moreover, on
the proposed study the objective will be, to design and analysis a CD.
