EXPANDABLE INTERVERTEBRAL SPACER

Abstract: an expandable interbody spacer for intervertebral fusion is provided. the interbody spacer includes an anterior spacer, at least two anterior hinge members having a first end and a second end, a first lateral spacer, a second lateral spacer, at least two posterior hinge members having a first end and a second end, and a posterior spacer. the anterior spacer is operatively coupled to the first ends of the anterior hinge members. the second end of the first anterior hinge member is operatively coupled to the first lateral spacer. the second end of the second anterior hinge member is operatively coupled to the second lateral spacer. the posterior spacer is operatively coupled to the first ends of the posterior hinge members. the second end of the first posterior hinge member is connected to the first lateral spacer. the second end of the second posterior hinge member is connected to the second lateral spacer. the interbody spacer is configured to expand bilaterally in a medial-lateral direction such that the first and second lateral spacers engage the lateral most aspects of the adjacent vertebrae.
