Intervertebral implant

摘要

An intervertebral implant comprising an intervertebral spacer and two fastener ties is disclosed. The intervertebral spacer may be formed having a body extending in a longitudinal direction. The intervertebral spacer may further include a first insertion face, a second face, and two recesses disposed at the ends of the body. The recesses may each be defined by a first extension, a second extension, and an end wall. Each of the two fastener ties may be secured to the first extension at a first end and a second end may be fastenable to the second face. The ties may pass around a spinous process in part and hold the spinous process within a recess. The first extension of the body may have a height relative to the bottom wall of the recess that is no greater than the height of the second extension.

主权项

1. An intervertebral implant for placing between the spinous processes of two adjacent vertebrae, the implant comprising:
an intervertebral spacer formed as a single part comprising a body having a longitudinal direction, presenting in said direction an insertion first face and a second face, and two recesses disposed at opposing ends along the longitudinal direction of the body, each recess being defined by a first extension extending from said insertion face, by a second extension extending from the second face of the body, and by an end wall; a first fastener tie having a first end and a second end, the first end secured to at least one of the first extensions of the body and a second end fastenable to the second face of the body; a second fastener tie having a first end and a second end, the first end secured to at least one of the first extensions of the body and a second end fastenable to the second face of the body; and a single blocking means for blocking the second ends of both the first and second fastener ties together, said blocking means being fastenable in a releasable manner on the second face of said body; wherein each first extension of the body presents a total height relative to the end wall of the recess that is less than a total height of each second extension, and that lies in the range of 1 mm to 3 mm.
