Abstract:
A prosthetic implant apparatus for facilitating fusion of adjacent vertebrae, comprising an implant member dimensioned to be at least partially positioned within an intervertebral space defined between adjacent vertebrae, the implant member including first and second vertebral engaging plates pivotally connected to each other about a pivot pin extending through corresponding aligned openings of the first and second engaging plates, and adapted for relative pivotal movement to respectively engage vertebral surfaces of the adjacent vertebrae, the implant member defining a longitudinal median plane extending between the engaging plates in equidistant relation therewith, the first and second engaging plates having discontinuous surfaces to engage the vertebral surfaces and promote bone ingrowth, and a displacement member associated with the engaging plates and being movable in a transverse direction relative to the longitudinal median plane, to cause relative movement of the engaging plates, to thereby at least laterally displace the engaging plates to supportingly engage the adjacent vertebrae.
