Translateral spinal implant
DC CAFCFirst Claim
1. A translateral spinal implant for insertion from the lateral aspect of the spine in the disc space between two adjacent vertebrae, said implant having a length that is greater than one half the transverse width of the vertebrae, said length being substantially greater than the depth of the vertebrae, and a height for contacting each of the two adjacent vertebrae.

Abstract
An oversized spinal implant for translateral 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 translateral 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 translateral 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 which any threads are able to penetrate the vertebrae.

34. A translateral spinal implant for insertion from the lateral aspect of the spine in the disc space between two adjacent vertebrae, comprising:
-
a plurality of modular members, each of said modular members having a length that is greater than one half the transverse width of the vertebrae, said length being substantially greater than the depth of the vertebrae, a width less than the depth of the vertebrae, and a height for contacting each of the two adjacent vertebrae, each of said modular members comprising; upper and lower walls, and side walls, said upper and lower walls forming a support structure including at least a portion of the interior surface of said upper and lower walls for bearing against the end plates of the adjacent vertebrae, whereby said plurality of modular members are capable of being inserted in between said two adjacent vertebrae. - View Dependent Claims (63, 67, 71)
