A prosthetic intervertebral spacer includes a body and an interface extending away from the body for use during implantation of the spacer. The interface can be a rail including a neck portion connected to the body and a lip portion connected to the neck portion. The lip portion can be wider than the neck portion in a direction extending between the top and bottom surfaces of the implant. Methods of implanting the spacer and tools used during such procedure are also provided. |
