<p>This invention is an oversized spinal implant (100) for trans-lateral insertion into the disc space between two vertebrae, a length that is greater than one half of the transverse width of the vertebrae, and is greater than the depth of the vertebrae. The trans-lateral implant of the present invention has a height that is greater than the height of the disc space between two adjacent vertebrae so as to engage both of the vertebrae. The width of the implant need be only slightly less than the depth of the vertebrae themselves. The trans-lateral spinal fusion implant of the present invention has more surface area of contact, and thus permits greater stability so as to withstand torque, and in the case of a threaded implant, increases the depth in which any threads are able to penetrate the vertebrae.</p> |
