Abstract
A method of replacing a nucleus pulposus in an intervertebral disc by filling the disc with a flowable augmentation material through a throughbore in a pedicle.
Claims27
A method of augmenting a nucleus pulposus in an intervertebral disc between first and second vertebrae, comprising the steps of:
- a) creating a throughbore from a pedicle of the first vertebra through an endplate of the first vertebra to access the nucleus pulposus, and
- b) filling the disc with a flowable augmentation material through the throughbore.
A method of augmenting a nucleus pulposus in an intervertebral disc between first and second vertebrae, comprising the steps of:
- a) creating a throughbore through an endplate of the first vertebra to access the nucleus pulposus, and
- b) repairing the endplate of the first vertebra.
A kit comprising:
- a) a flowable nucleus pulposus augmentation material,
- b) a fill tube, and
- c) an apparatus comprising a pedicle screw.
A kit comprising:
- a) a flowable nucleus pulposus augmentation material, and
- b) a cannulated pedicle screw.
A method of augmenting a first nucleus pulposus in an intervertebral disc between first and second vertebrae, comprising the steps of:
- a) accessing a first nucleus pulposus between the first and second vertebrae,
- b) removing at least a portion of the first nucleus pulposus to create a first disc space,
- c) creating a throughbore from a first endplate of the first vertebra through the second endplate of the first vertebra to access a second nucleus pulposus,
- d) removing at least a portion of the second nucleus pulposus to create a second disc space,
- e) filling the first disc space with a component selected from the group consisting of a flowable augmentation material, a motion disc and a fusion device, and
- f) filling the second disc space with a component selected from the group consisting of a flowable augmentation material, a motion disc and a fusion device.
