Abstract

The SB Charité I artificial disc was developed in 1982 by Schellnack and Büttner-Janz and modified as the Mark II version in 1984. Both types were manufactured in the former German Democratic Republic (GDR). Today's design, the SB Charité III, was first produced by LINK in 1987. Five sizes of the artificial disc in various angulations are available today, with a double coating of titanium/calciumphosphate. Designed with a three-component set-up, the SB Charité mimics the physiological segmental motion. The possibility of translation in the SB Charité provides proper biomechanical function and protects the zygapophysial joints. Results of biomechanical testing showed a sufficient cold-flow resistance of the UHMWPE (Ultra High Molecular Weight Polyethylene) sliding core and confirmed the negligible abrasion rate. The LINK SB Charité disc is a safe and effective operative treatment for discogenic low back pain. Long-term results (10 years and more) have been published.

摘要

SB Charité I型人工椎间盘由舍尔纳克和布特纳-扬茨于1982年研发,并于1984年改进为Mark II版本。这两种类型均在前德意志民主共和国(东德)生产。如今的设计,即SB Charité III型,于1987年由LINK首次生产。如今有五种不同角度的人工椎间盘尺寸可供选择,采用钛/磷酸钙双层涂层。SB Charité采用三分组件设计,可模拟生理节段运动。SB Charité中的平移可能性提供了适当的生物力学功能,并保护了小关节。生物力学测试结果表明,超高分子量聚乙烯(UHMWPE)滑动核心具有足够的抗冷流性,并证实磨损率可忽略不计。LINK SB Charité椎间盘是治疗椎间盘源性下腰痛的一种安全有效的手术方法。长期结果(10年及以上)已发表。
