摘要： An intervertebral disc prosthesis comprises a first plate including a socket and a second plate comprising a recess. A core is sandwiched between the socket and the recess. The core includes a domed surface and a plug portion. The first plate is configured to rotate upon the domed surface of the core. The second plate is substantially fixed to the core, with the plug portion engaging the recess. The core may be press-fit into the second plate during assembly of the intervertebral disc prosthesis. The first plate and second plate both include tabs that define notches, wherein the notches are configured to engage prongs of a disc insertion tool. Teeth provided on the first plate and the second plate assist in fixing the first plate and the second plate to the vertebral bodies.

摘要： Methods and devices for locking a fastener in a thru-bore are provided herein. In one exemplary embodiment, a spinal anchor is provided that includes a bone engaging fastener, an anti-backout mechanism, and a locking mechanism. The anti-backout mechanism can be movable between a retracted position in which it is disposed within the fastener and a deployed position in which is extends from the bone engaging fastener. The locking mechanism can be matable to the bone engaging fastener and can be configured to move the anti-backout mechanism from the retracted position to the deployed position. In the deployed position, the anti-backout mechanism can prevent the bone engaging fastener from backing out of a thru-bore in a spinal plate.
摘要翻译：本文提供了用于将紧固件锁定在通孔中的方法和装置。在一个示例性实施例中，提供了一种脊椎锚固件，其包括骨接合紧固件，防止退避机构和锁定机构。防止退出机构可以在其设置在紧固件内的缩回位置和从骨接合紧固件延伸的展开位置之间移动。所述锁定机构可以与所述骨接合紧固件配合，并且可构造成将所述防止退出机构从所述缩回位置移动到展开位置。在展开位置，防止退出机构可以防止骨接合紧固件从脊椎板中的通孔中退出。
