Abstract
A device is disclosed for securing a spinal rod to the spine which includes a head portion configured to receive a spinal rod, a locking cap configured to engage the head portion and the spinal rod upon rotation of the locking cap relative to the head portion to secure the position of the head portion relative to the spinal rod, and a fastener portion depending from the head portion and configured to engage the spine.
Claims68
A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough configured to receive a spinal rod;
- b) a locking cap configured to engage an interior camming surface of the channel and an exterior surface of the spinal rod upon rotation of the locking cap relative to the head portion to secure the position of the head portion relative to the spinal rod;
- and
- c) a fastener portion formed monolithic with and depending from the head portion and configured to engage the spine.

A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough defining a vertical axis and a horizontal axis, and configured to receive a spinal rod along the horizontal axis;
- b) a locking cap configured for reception by the head portion along the vertical axis of the channel and adapted to engage an interior surface of the channel and an exterior surface of the spinal rod upon rotation of the locking cap about the vertical axis to secure the position of the head portion relative to the spinal rod;
- and
- c) a fastener portion formed monolithic with and depending from the head portion and configured to engage the spine.
1 more element
A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough for receiving a spinal rod;
- b) a locking cap configured to cooperate with an interior camming surface of the channel and an exterior surface of the spinal rod upon rotation of the locking cap relative to the head portion between an unlocked position and a locked position to secure the position of the head portion relative to the spinal rod;
- and
- c) a fastener portion formed monolithic with and depending from the head portion and configured to engage the spine.
1 more element
A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough for receiving a spinal rod, the channel being bounded by opposed side walls, each side wall having an arcuate engagement slot defined therein,
- b) a locking cap having a bottom surface configured to accommodate a spinal rod extending through the channel of the head portion and including opposed arcuate engagement flanges configured for cammed reception in the opposed arcuate engagement slots of the head portion upon rotation of the locking cap relative to the head portion to secure the position of the head portion relative to the spinal rod;
- and
- c) a fastener portion formed monolithic with and depending from the head portion and configured to engage the spine.
1 more element
A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough configured to receive a spinal rod;
- b) a locking cap including a first portion configured to engage an interior surface of the head portion and a second portion configured to engage an exterior surface of a spinal rod received by the channel to secure the position of the head portion relative to the spinal rod;
- and
- c) a fastener portion depending from the head portion and configured to engage the spine.
1 more element
A device for securing a spinal rod to the spine comprising:
- a) a head portion having a channel extending therethrough configured to receive a spinal rod;
- b) a locking cap including an upper portion configured to engage an interior surface of the head portion and a lower portion configured to engage an exterior surface of a spinal rod received by the channel to secure the position of the head portion relative to the spinal rod upon rotation of the upper portion relative to the lower portion and the head portion;
- and
- C) a fastener portion depending from the head portion and configured to engage the spine.
1 more element
A device for securing a spinal rod to the spine comprising:
- a) a head portion defining a central axis and having a channel extending therethrough oriented perpendicular to the central axis and configured to receive a spinal rod;
- b) a locking cap including an upper portion configured to engage an interior surface of the head portion and a lower portion configured to engage an exterior surface of a spinal rod received by the channel to secure the position of the head portion relative to the spinal rod upon rotation of the upper portion relative to the lower portion about the central axis of the head portion;
- and
- c) a fastener portion depending from the head portion to engage the spine and mounted for angular movement relative to the central axis of the head portion.
