Method and apparatus for correcting spinal deformity

An apparatus for correcting spinal deformity, said apparatus comprising:

• first and second anchors for implantation into first and second vertebral bodies, respectively, said anchors, when implanted, being resistant to toggling in the vertebral bodies and to being pulled from the vertebral bodies;
• each of said first and second anchors including a platform having at least one passage extending transversely through said platform;
• each of said first and second anchors further including screw means for embedding into one of the vertebral bodies upon rotation of said platform, said screw means projecting from said platform on each of said first and second anchors and having a tip portion at a distal end which penetrates into a respective one of the vertebral bodies as said platform is rotated;
• and
• at least one cable extending through said at least one passage in said platform on each of said first and second anchors, said at least one cable being tensionable to cause relative movement between the first and second vertebral bodies;
• said platform on each of said first and second anchors including a plurality of parallel passages extending transversely through said platform;
• said platform on each of said first and second anchors further including an oppositely disposed pair of radially extending wing sections, one of said plurality of parallel passages extending through each of said pair of wing sections on each of said first and second anchors.

An apparatus for correcting spinal deformity, said apparatus comprising:

• at least two anchors for implantation into separate vertebral bodies, said at least two anchors, when implanted, being resistant to toggling in the vertebral bodies and to being pulled from the vertebral bodies;
• each of said at least two anchors including a platform having at least one passage extending transversely through said platform;
• each of said at least two anchors further including at least two helical spikes for embedding into one of the vertebral bodies upon rotation of said platform, said at least two helical spikes projecting from said platform on each of said at least two anchors and having tip portions at a distal end which penetrate into a respective one of the vertebral bodies as said platform is rotated;
• at least one cable extending through said at least one passage in said platform on each of said at least two anchors, said at least one cable being tensionable to cause relative movement between the vertebral bodies;
• and
• a spinal fixation implant extending between and is connectable with said platform on each of said at least two anchors.

A method for correcting spinal deformity, said method comprising the steps of:

• providing at least two anchors for implantation into separate vertebral bodies, each of the at least two anchors including a platform having at least one passage extending transversely through the platform, each of the at least two anchors further including screw means for embedding into one of the vertebral bodies upon rotation of the platform;
• implanting the at least two anchors in the separate vertebral bodies;
• connecting the at least two anchors with at least one cable that extends through the at least one passage in the platform on each of the at least two anchors;
• tensioning the at least one cable to cause relative movement between the vertebral bodies;
• and
• connecting a spinal fixation implant to the platform on each of the at least two anchors.

An apparatus for correcting spinal deformity, said apparatus comprising:

• first and second anchors for implantation into first and second vertebral bodies, respectively, said anchors, when implanted, being resistant to toggling in the vertebral bodies and to being pulled from the vertebral bodies;
• each of said first and second anchors having a longitudinal axis and including a platform having at least one passage extending transversely through said platform, each of said platforms having a first surface that is solid and that extends generally transverse to said longitudinal axis;
• each of said first and second anchors further including at least two helical spikes for embedding into one of the vertebral bodies upon rotation of said platform, said at least two helical spikes projecting tangentially from said first surface platform on each of said first and second anchors and having a tip portion at a distal end which penetrates into a respective one of the vertebral bodies as said platform is rotated;
• and
• at least one cable extending through said at least one passage in said platform on each of said first and second anchors, said at least one cable being tensionable to cause relative movement between the first and second vertebral bodies.
