摘要:
Embodiments disclosed herein provide a disc implant for maintaining intervertebral spacing and stability within the human spine. In some embodiments, the disc implant includes complementary members between vertebral engaging plates. A first engaging plate may have a convex portion that allows anteroposterior translation of a first member relative to the first engaging plate. Movement of the first member relative to the first engaging plate allows lateral movement of vertebrae adjacent to the engaging plates. The first member may be coupled to a second member via complementary shapes such as a projection and a recess. The second member may have a convex portion that complements a recess of a second engaging plate. The recess may be concave with an arcuate cross-sectional shape in an anteroposterior plane. Movement of the second engaging plate relative to the second member allows for anteroposterior movement of vertebrae adjacent to the engaging plates.
