AbstractAn interbody spinal prosthetic implant is placed between adjacent vertebral bodies of the vertebrae of a spine to maintain a desired orientation and spacing between the adjacent vertebral bodies and support the adjacent vertebral bodies for fusion at the desired orientation and spacing, the prosthetic implant including a rigid member of biocompatible material having vertically opposite upper and lower load-bearing surfaces spaced apart a distance providing a height corresponding to the desired spacing, the rigid member having a wedge-shaped configuration in horizontal planes, the wedge-shaped configuration tapering from relatively narrower widths adjacent the front end toward relatively wider widths adjacent the rear end of the rigid body and providing the rigid body with an overall width wider than the height of the rigid body, and an ogival tip at the front end of the rigid member.
