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.
Claims12
A method of implanting an intervertebral implant into an intervertebral space, the method comprising the steps of:
- inserting the intervertebral implant into the intervertebral disc space in a distal direction, the implant including:
- a spacer that defines a proximal end and a distal end that is spaced from the proximal end in the distal direction, wherein the proximal end comprises cancellous bone graft material and no cortical bone graft material, and the distal end includes cortical bone graft material and no cancellous bone graft material;
- and
- a frame including a support member that is configured to extend along a portion of the cancellous bone graft material, such that the cancellous bone graft material is disposed between the support member and at least a portion of the cortical bone graft material;
- and
- driving at least one fixation element through a respective fixation element receiving aperture of the support member, through the cancellous bone graft material without passing through any of the cortical bone graft material, and into a vertebral body that partially defines the intervertebral space.
