VERTEBRAL INTERBODY SPACER
Document Type and Number:
Japanese Patent JP2017136410
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vertebral interbody spacer creating and maintaining a desired orientation and spacing between the adjacent vertebral bodies of the spine.SOLUTION: An interbody spacer 20 includes an elongated body with a maximum width between opposite side walls and a maximum height between upper and lower bearing surfaces. The interbody spacer also includes a leading end nose 26 connecting the side walls to facilitate insertion of the interbody spacer into a disc space between vertebrae in an insertion orientation, from which the interbody device is then rotated to position the upper and lower bearing surfaces 22 and 24 in contact with the endplates of the adjacent vertebrae. The leading end nose forms a blunt convex nose between the upper and lower bearing surfaces to maximize the bearing surface area available to contact the adjacent endplates.SELECTED DRAWING: Figure 1
