Abstract
Methods and devices are disclosed for treating the vertebral column. An implant for treating the spine is provided comprising at least two articulations between the spacer and the bone facing surface of the fixation plate. Another implant for treating the spine is also provided, comprising two or more fixation plates attached to a spacer with two or more articulations, wherein the fixation plates are independently movable.
Claims35
An implant for treating the spine, comprising:
- a fixation plate having an access surface and a bone facing surface;
- a spacer;
- and
- at least two articulations between the spacer and the bone facing surface of the fixation plate.
1 more element
An implant for treating the spine, comprising:
- a fixation plate having an access surface and a bone facing surface, an upper portion and a lower portion;
- a spacer;
- at least one member interconnecting the fixation plate and spacer;
- at least one articulation between the fixation plate and the at least one member;
- and
- at least one articulation between the spacer and the at least one member;
- wherein the articulations provide for rotational and cam movement between the spacer and the fixation plate;
- wherein in a first configuration, the distance between the fixation plate and the spacer is at a minimum;
- wherein in a second configuration, the distance between the fixation plate and the spacer is at a maximum.
6 more elements
A method for treating a spine, comprising:
- providing an implant for treating the spine comprising a fixation plate having an access surface and a bone facing surface, an upper portion and a lower portion, a spacer, at least two articulations between the spacer and the bone facing surface of the fixation plate and at least one member between the at least two articulations, wherein the at least two articulations provide for rotational and cam movement between the spacer and the fixation plate, wherein in a first configuration, the distance between the fixation plate and the spacer is at a minimum, wherein in a second configuration, the distance between the fixation plate and the spacer is at a maximum;
- adjusting the implant to any configuration between, or including, the first configuration and second configuration;
- inserting the spacer into an intervertebral space between a first vertebra and a second vertebra;
- attaching the upper portion of the fixation plate to the first vertebra;
- and
- attaching the lower portion of the fixation plate to the second vertebra.
3 more elements
An implant for treating the spine, comprising:
- two or more fixation plates;
- a spacer;
- and
- two or more articulations between the spacer and the two or more fixation plates;
- wherein the two or more fixation plates are independently movable.
2 more elements
A method for treating a spine, comprising:
- providing an implant for treating the spine comprising a first and a second fixation plate, a spacer, and a first and a second articulation between the spacer and the first and the second fixation plates, wherein the fixation plates are independently movable;
- providing a first vertebra and a second vertebra adjacent the first vertebra, each vertebra comprising a corresponding first portion and a second portion;
- coupling a first elongate pin with the first portion of the first vertebra;
- coupling a second elongate pin with the second portion of the second vertebra;
- increasing an intervertebral space between the first vertebra and the second vertebra by separating the first and second elongate pins along a longitudinal axis of the vertebral column;
- inserting the spacer into the intervertebral space between the first vertebra and the second vertebra;
- positioning the first fixation plate to lie generally flat on a second portion of the first vertebra, wherein the first fixation plate is offset from the first elongate pin;
- attaching the first fixation plate to the first vertebra;
- positioning the second fixation plate in generally the opposite direction as the first fixation plate to lie generally flat on a first portion of the second vertebra, wherein the second fixation plate is offset from the second elongate pin;
- and
- attaching the second fixation plate to the second vertebra.

- positioning the first fixation plate to lie generally flat on the first vertebra;
- attaching the first fixation plate to the first vertebra;
- positioning the second fixation plate in generally the opposite direction as the first fixation plate to lie generally flat on the second vertebra;
- and
- attaching the second fixation plate to the second vertebra.
