Abstract
An intervertebral space distraction and implantable device assembly provides sequentially axially wider spacers that are to be sequentially inserted into and removed from an intervertebral space to widen the space until a desired anatomical spacing of the adjacent vertebral bones is restored. The set of spacers includes a porous spacer that is as wide as the spacer that restores the desired anatomical spacing. The porous spacer can therefore be left implanted in the intervertebral space to promote fusion of the adjacent vertebral bones.
Claims16
An intervertebral spacer set, comprising a plurality of intervertebral spacers, each having a respective axial width, at least one of the axial widths being unique among the plurality, at least one of the plurality having a porous surface, at least one of the plurality having a beveled perimetrical edge.
An intervertebral spacer set, comprising a plurality of intervertebral spacers, each having a respective axial width, at least one of the axial widths being unique among the plurality, at least one of the plurality having a porous surface, at least one of the plurality having an axially medial groove.
An intervertebral implant set, comprising a plurality of intervertebral implants, each having a respective axial width, at least one of the axial widths being unique among the plurality, at least one of the plurality having at least one of a beveled perimetrical edge and an axially medial groove.
