Methods and systems for interbody implant and bone graft delivery

摘要

A spacer for implantation between adjacent vertebrae is provided. The spacer includes a distal end and a proximal end. The spacer also includes top and bottom surfaces spaced by sides. The top and bottom surface define a height, and the sides define a width. Each of the sides of the spacer may include a depressed region sunk into the side including a sloped surface at least toward the proximal end of the spacer. The distance between the sloped surfaces of the sides may decrease proximally to form a web having a leading edge proximate to the proximal end of the spacer. The web may be sized and configured to aid distribution of bone graft material to either side of the spacer, wherein bone graft material is supplied to a site of interest is distributed to at least one side of the spacer.

主权项

1. A spacer for maintaining the position of adjacent vertebrae, the spacer including:
a distal end and a proximal end; top and bottom surfaces spaced by at least two sides, the top and bottom surfaces defining a height, and the sides defining a width; wherein each of the two sides comprises a depressed region sunk into the side including a sloped surface at least toward the proximal end of the spacer, the distance between the sloped surfaces of the sides decreasing proximally to form a web, and wherein the web is sized and configured to aid distribution of bone graft material to either side of the spacer, wherein the web separates a top cap and a bottom cap at least at the proximal end of the spacer, the thickness of the web decreasing proximally to form a wedge, and wherein the top cap and the bottom cap include surfaces that taper such that the top cap and bottom cap become narrower toward the proximal end of the spacer.
