    Abstract: A prosthesis having: a) a first assembly with a first base portion to be placed against, and operatively secured to, a patient's first bone; and b) a second assembly with a second base portion to be placed against, and operatively secured to, a patient's second bone. The first and second assemblies respectively define first and second surfaces that cooperate with each other to guide articulated movement between the first and second bones. At least one of the first and second base portions is configured to cooperate with a separate first component defining at least a part of one of the first and second surfaces to maintain the first component in an operative state. A second component is configured to define at least a part of the one of the first and second surfaces and can be placed in an operative state selectively in place of the first component.

    Abstract: An artificial cervical vertebrae composite joint is composed of two upper and lower fixing members disposed vertically symmetrically, a cervical vertebrae body member, and two connection members, the cervical vertebrae body member being connected between the fixing members through the connection members. The fixing members each have an L shape and comprise a front wing part and a base part. A locking screw hole is formed in the front wing part, and a skidproof groove provided with an inverted tooth and a protrusion is disposed on a middle portion of the base part. A bone grafting hole is transversely disposed through a middle portion of the cervical vertebrae body member, and two cavities are disposed on both upper and lower sides of the cervical vertebrae body member at an axial center of the cervical vertebrae body member to mount the connection members. The connection member has one end mounted in the cavity by means of a fixing ring, and another end connected with the fixing member to form a stable sliding-trough type ball-and-socket joint.

    Abstract translation: 人造颈椎复合关节由垂直对称设置的两个上下固定构件，颈椎体构件和两个连接构件组成，颈椎主体构件通过连接构件连接在固定构件之间。 固定构件各自具有L形并且包括前翼部和基部。 在前翼部形成有锁定螺纹孔，在基部的中部设置有设置有反转齿和突起的防滑槽。 骨移植孔横向设置穿过颈椎体部件的中间部分，并且在颈椎主体部件的轴向中心处，在颈椎体部件的上下两侧设置两个空腔，以安装连接部件 。 连接构件通过固定环一端安装在空腔中，另一端与固定构件连接，形成稳定的滑槽式球窝接头。
