Abstract

See full text

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.
