Abstract

Abstract:

BACKGROUND: Artificial cervical disc replacement has been widely used in clinical cervical surgery. Further research of biomechanics of the artificial cervical disc used in the surgery is needed.
OBJECTIVE: To review the structure, material types and in vitro biomechanical study of the existed artificial cervical disc, and to prospect the development in the future.
METHODS: The PubMed databases and CNKI database were searched with key words of “artificial cervical disc, prosthesis, structure, material, biomechanical study” in English and Chinese respectively. The articles related to artificial cervical disc structure, material, and in vitro biomechanics were included. The researches in the recent 5 years were collected, and the repetitive studies were excluded. A total of 36 articles were discussed for interview.
RESULTS AND CONCLUSION: The existed cervical artificial disc products mainly use the structure of the metal-polymer, and most are the semi-restrictive and non-restrictive structure, dimension series are more perfect and all of them are the imported products. The analysis and the summary of the existed products show that the cervical artificial disc has major development space in three aspects of structure design, oriented population design and material improvement, and the improvement of the material can be considered from the aspects of ndplate material, nucleus pulposus material and surface coating material.

Key words: bone and joint implants, review of bone and joint implants, artificial cervical disc, collar disk, prosthesis, structure, materials, endplate material, nucleus pulposus material, surface coating, in vitro biomechanics, ministerial grants-supported paper
