1. A prosthetic intervertebral spacer comprising:
- a body having a front end, a curved rear end, anterior and posterior sides each extending between the front and rear ends, and top and bottom surfaces each connecting the anterior and posterior sides and extending between the front and rear ends;
an interface extending away from the body, the interface being a rail including a neck portion connected to the body and a lip portion connected to the neck portion, the lip portion being wider than the neck portion in a direction extending between the top and bottom surfaces, anda notch extending into the body from the top surface to the bottom surface and separating the interface into first and second segments, the notch defining an axis that extends between the top and bottom surfaces.

19. A prosthetic intervertebral spacer comprising:
-
a body having a front end, a curved rear end, anterior and posterior sides each extending between the front and rear ends, and top and bottom surfaces each connecting the anterior and posterior sides and extending between the front and rear ends, the front end mating with the anterior side at a transition portion that is curved, the transition portion configured to interact with an annulus fibrosus of an intervertebral disc to cause rotation of the spacer during insertion of the spacer; an interface extending away from the body, and a notch extending into the body from the top surface to the bottom surface and separating the interface into first and second segments, the notch defining an axis that extends between the top and bottom surfaces. - View Dependent Claims (20)
