Abstract
An intervertebral implant frame that is configured to engage a spacer can include a pair of arms that extend longitudinally from a support member such that the arms engage the spacer. The spacer can be made from bone graft, and include a first spacer body made of cortical bone, and a second spacer body made of cancellous bone.
Claims18
An expansion instrument configured to expand an intervertebral implant frame to receive an intervertebral spacer, the expansion instrument comprising:
- a first member defining a first base and a first instrument arm that extends from the first base and is configured to releasably couple to a first frame arm of the intervertebral implant frame, wherein the first member defines a first gap that extends into the first base;
- a second member defining a second base and a second instrument arm that extends from the second base and is configured to releasably couple to a second frame arm of the intervertebral implant frame;
- wherein the second base is configured to be received in the first gap, such that the second base is slidable relative to the first base in the first gap so as to cause the respective first and second instrument arms to move away from each other.
