An intervertebral system comprises an inserter head and an intervertebral disc implant. The inserter head has a body having a leading end with a concave surface, said concave surface having an upper end and a lower end, and a first pin projecting from said concave surface adjacent said upper- end of said concave surface, A pair of second pins spaced from one another projects from said concave surface adjacent said lower end of said concave surface. A wedge projects from said concave surface and is disposed between said first pin and said pair of second pins, The spacing between the second pins relative to the spacing between a pair of openings in the implant is different so as to form a friction lock. |
