Claims27
An apparatus for alignment of vertebrae, comprising:
- a surgical rod;
- a hook-shaped member adapted and configured for receiving a portion of bone within the hook, said member defining an aperture therethrough;
- an anchor having a body adapted and configured for fixation into a bone and a head, said body passing through the aperture when fixed to the bone;
- and
- a cable coupling said hook-shaped member to said rod.

An apparatus for alignment of vertebrae, comprising:
- a surgical rod;
- a hook-shaped member adapted and configured for receiving a portion of bone within the hook;
- a cable coupling said hook-shaped member to said rod and having first and second ends, one of said first and second ends of said cable including a spherical portion;
- and
- a connecting member defining a first pocket for receiving therein the one end, said first pocket including a spherical recess adapted and configured for receiving therein the spherical end portion of the one end.
2 more elements
An apparatus for alignment of vertebrae, comprising:
- a surgical rod having a first cross-sectional shape;
- a hook-shaped member adapted and configured for receiving a portion of bone within the hook;
- a cable coupling said hook-shaped member to said rod and having first and second ends;
- and
- a connecting member having a first extended portion connected to the first end of said cable and a second extended portion connected to the second end of said cable, and having a middle section between the first and second extended portions, the middle section having a second cross-sectional shape generally complementary to the cross-sectional shape of said rod.
2 more elements
An apparatus for alignment of vertebrae, comprising:
- a surgical rod;
- a hook-shaped member including first and second arms connected at one end and spaced apart at the other end to form a pocket therebetween for receiving a portion of bone, one of said arms defining an open slot;
- a bone anchor coupling said hook-shaped member to a bone;
- a cable coupling said hook-shaped member to said rod and having first and second ends, a portion of said cable being received within the open slot;
- and
- a connecting member having a first extended portion connected to the first end of said cable and a second extended portion connected to the second end of said cable and a middle section between the first extended portion and the second extended portion.
3 more elements
An apparatus for alignment of vertebrae, comprising:
- a surgical rod;
- a bone anchor having a head and a body adapted and configured for fixation into a bone, said head defining an aperture therethrough;
- a cable coupling said bone anchor to said rod and having first and second ends, a portion of said cable passing through the aperture;
- and
- a connecting member having a first extended portion connected to the first end of said cable and a second extended portion connected to the second end of said cable and a middle section between the first extended portion and the second extended portion, wherein the middle section spaces apart said first and second extended portions such that said cable does not contact said rod after tightening.
