Abstract:
1. An intervertebral implant, comprising: a spacer having a distal end wall, a proximal end wall, a first lateral wall, and a second lateral wall, where the first lateral wall and the second lateral wall extend from the distal end wall to the proximal end wall, the spacer further having a top surface and a bottom surface opposite the top surface; a locking mechanism situated at the proximal end wall; a receiving opening extending into the proximal end wall; a cage having a first portion and a second portion, where the first portion is configured to engage the receiving opening such that a distal end of the first portion is maintained proximal of the distal end wall and the second portion has discontinuous threads to engage vertebrae; and wherein the first portion extends distal of the second portion such that the distal end of the first portion is distal of the discontinuous threads; and wherein: the cage has an axis of rotation; the second portion of the cage extends a first distance in a first direction perpendicular to the axis of rotation; the second portion of the cage extends a second distance in a second direction perpendicular to the axis of rotation and perpendicular to the first direction, where the second distance is greater than the first distance; and when the first portion of the cage engages the receiving opening and the distal end of the first portion is maintained proximal of the distal end wall, the second portion of the cage is positionable between the first lateral wall, the second lateral wall, the top surface, and the bottom surface of the spacer.
