Claims14
A surgical implant, comprising:
- a lower platform that is longitudinally elongated;
- an upper platform that is longitudinally elongated and is pivotally connected to the lower platform at a first end thereof;
- a wedge block disposed between the upper platform and the lower platform at a second opposing end thereof;
- a longitudinally elongated graft tube disposed between the upper platform and the lower platform, comprising a hollow center cavity, a head longitudinal end, an opposing tail longitudinal end, and a pair of opposing axle engagement hubs adjacent the tail longitudinal end;
- a jack screw disposed through the wedge block with a head of the jack screw facing inward of the upper platform and the lower platform;
- and
- a pair of connecting screws,
- wherein the head longitudinal end of the graft tube comprises threads to engage the jack screw and an aperture is defined through the tail longitudinal end to allow for a tool to be inserted to engage the head of the jack screw,
- wherein the lower platform defines a pair of axle hub engagement slots corresponding to the pair of axle engagement hubs which are sized and shaped to receive the pair of axle engagement hubs therein,
- wherein the upper platform defines a pair of axle hub engagement slots corresponding to the pair of axle engagement hubs which are sized and shaped to receive the pair of axle engagement hubs therein, and
- wherein each connecting screw is disposed through a respective one of the axle engagement hubs, axle engagement slots for the upper platform and the engagement slots for the lower platform, and
- wherein the upper and lower platforms are constrained to pivot about the pair of connecting screws.

A method of performing spinal fusion surgical procedure, comprising:
- introducing a spinal implant to a vertebral cavity in a collapsed state, the vertebral cavity disposed between opposing vertebral endplates;
- turning in situ a jack screw that is disposed in a graft tube of the implant and a wedge block that engages a longitudinal end of the spinal implant to draw the wedge block inward of the spinal implant to pivot an upper platform of the spinal implant outwardly relative to a lower platform of the spinal implant, wherein the pivot point is adjacent a longitudinal end of the spinal implant opposite the longitudinal end that engages the wedge block;
- and
- introducing fill material in situ into the spinal implant, passing the fill material through the graft tube and outward into a flexible container defined by flexible mesh material provided to lateral sides of the spinal implant.
