Abstract

Nowadays, there are lots of designs of artificial disc produce for the total disc replacement but the long term effect still under observation. Some of complications cause by the effect of artificial disc design especially on the polyethylene core. This study is to investigate the effect of the design artificial disc on compressive stress. This study involve of development of three dimensional modeling using computer-aided design software (CAD) to construct Prodisc-L artificial disc and a three-dimensional nonlinear finite element of vertebral body L4-L5. A simulation study is undertaken by Marc Mentat and Solidworks software to analyze the effect of the prostheses design. The result shows that the highest compressive stress occurred at polyethylene core which lead to polyethylene damage and may be relevant reason of the failure mode for lumbar artificial disc replacement. The analysis of the effect of implant design using FE analysis may help in identifying the weakness of the design and prevent the long-term failure of implant.
