Abstract:
1. A spinal fusion interbody spacer assembly for maintaining a selected intervertebral spacing between an adjacent pair of vertebrae having mutually facing vertebral surfaces, each vertebral surface including an inner central region and an outer edge region, said assembly comprising: (a) an interbody spacer member sized and shaped so as to be adapted to enable implanting of said member between and in touching relationship at both a top and bottom of the spacer respectively with an adjacent pair of vertebrae to engage and support the central regions of mutually facing vertebral surfaces of the vertebrae; said spacer member having a longitudinal axis; said spacer member having front and rear ends on opposite ends of said longitudinal axis; (b) an end cap joinable with said spacer member at said front end and configured in such a manner as to be adapted to enable implanting between facing vertebrae so as to resist subsidence of the vertebrae about the assembly, said end cap including a pair of wing portions extending laterally on opposite sides of said end cap; said wing portions having an arcuate curvature and convex outer surfaces; the wing portions being sized and shaped so as to have upper and lower wing surfaces; each wing surface being configured to engage and support an anterior edge from a center to lateral sides of respective facing vertebral surfaces; and (c) said end cap being removably securable to said spacer member and cooperating therewith to maintain the selected intervertebral spacing between the vertebrae.
