Artificial expansile total lumbar and thoracic discs for posterior placement without supplemental instrumentation and its adaptation for anterior placement of artificial cervical, thoracic and lumbar discs
摘要：
A total artificial expansible disc having at least two pairs of substantially parallel shells, which move in multiple directions defined by at least two axes, is disclosed. Several methods for implanting the total artificial expansile disc are also disclosed. The total artificial expansile disc occupies a space defined by a pair of vertebral endplates. An expansion device, which preferably includes a jackscrew mechanism, moves the pairs of shells in multiple directions. A core is disposed between the pairs of shells, and the core permits the vertebral endplates to move relative to one another.
摘要（中）：

公开了一种总人造可膨胀盘，其具有至少两对基本平行的壳，其在由至少两个轴限定的多个方向上移动。 还公开了用于植入总人造扩张盘的几种方法。 总人造膨胀盘占据一对椎骨终板限定的空间。 一种膨胀装置，其优选地包括一个起重螺旋机构，在多个方向上移动该对壳。 核心设置在成对的壳之间，并且核心允许椎骨终板相对于彼此移动。
