摘要：
An intervertebral prosthetic disc that is configured to be installed within an intervertebral space that can be established between an inferior vertebra and a superior vertebra is disclosed. The intervertebral prosthetic disc includes an inferior articular half that can be configured to engage the inferior vertebra and a superior articular half that can be configured to engage the superior vertebra. The inferior articular half can be configured to cooperate with the superior articular half to allow relative angular motion between the inferior vertebra and the superior vertebra when installed. Further, the intervertebral prosthetic device can be sized and shaped to pass through a psoas muscle without injuring a spinal cord or a sympathetic chain.
