Abstract
A hybrid spinal implant for performing an intervertebral fusion procedure can include a pair of spacers separated by an expandable container that are formed of a porous titanium scaffold material. A connecting rod can span longitudinally between the pair of spacers. The spacers can be formed of titanium or PEEK, with endplates that are formed of the porous titanium scaffold material. The endplates can be bioactive. Exposed surfaces of the porous titanium scaffold material can be coated in a snag-preventing substance. The expandable container can be formed of a mesh material.
Claims19
A hybrid spinal implant for performing an intervertebral fusion on adjacent vertebral bodies in a patient, and for being located in a space between opposing end plates of the adjacent vertebral bodies, the hybrid spinal implant comprising:
- a first spacer, defining a top side oriented to contact a first one of the opposing end plates when the hybrid spinal implant is implanted in the space between opposing end plates and an opposing bottom side oriented to contact a second one of the opposing end plates when the hybrid spinal implant is implanted in the space between opposing end plates;
- a second spacer;
- a connecting rod spanning longitudinally between the first spacer and the second spacer;
- and
- a porous and expandable enclosed container disposed longitudinally between the first spacer and the second spacer, wherein the connecting rod passes through the expandable enclosed container in a direction parallel to the opposing end plates of the adjacent vertebral bodies when the hybrid spinal implant is located in the space between opposing end plates of the adjacent vertebral bodies,
- wherein a longitudinal end of the connecting rod is secured to the first spacer via a threaded fastener that is threaded into the first spacer sufficiently to engage a detent or recess defined in the connecting rod, and
- wherein each of the first spacer and the second spacer comprise a porous titanium scaffold material.
A method of placing a hybrid spinal implant for intervertebral fusion between adjacent vertebral bodies in a patient, wherein the hybrid spinal implant comprises a first spacer, a second spacer spaced apart from the first spacer and an expandable container disposed between the first spacer and the second spacer, and wherein the first spacer defines a height dimension perpendicular to respective endplates of the adjacent vertebral bodies, the method comprising:
- forming the first and second spacers from a porous titanium scaffold material;
- inserting the hybrid spinal implant in a space between the adjacent vertebral bodies so that the implant is oriented such that respective opposing surfaces of the first spacer and the second spacer respectively contacts both of the adjacent vertebral bodies simultaneously;
- and
- without altering the height dimension of the first spacer, filling the expandable container with fill material such that the expandable container expands to mutually contact both of the adjacent vertebral bodies.
