Abstract
Systems, devices and methods for vertebral fusion and SI joint stabilization.
Claims39
A method of fusing vertebrae and stabilizing sacro-iliac joints of a subject, comprising:
- implanting at least a portion of a fusion cage between an S1 vertebra and an L5 vertebra;
- implanting a first SI joint stabilizing member such that,
- a cage end region of the first SI joint stabilizing member interfaces with a first lateral portion of the fusion cage,
- the first SI joint stabilizing member extends through an S1 endplate,
- an ilium end of the first SI joint stabilizing member is implanted in a first ilium and is posterior, lateral and caudal relative to the fusion cage, and
- an intermediate region of the first SI joint stabilizing member that is between the ilium end and the cage end region is implanted across a first SI joint;
- and
- implanting a second SI joint stabilizing member such that,
- a cage end region of the second SI joint stabilizing member interfaces with a second lateral portion of the fusion cage,
- the second SI joint stabilizing member extends through the S1 endplate,
- an ilium end of the second SI joint stabilizing member is implanted in a second ilium and is posterior, lateral and caudal relative to the fusion cage, and
- an intermediate region of the second SI joint stabilizing member that is between the ilium end and the cage end region of the second SI joint stabilizing member is implanted across a second SI joint.

A system for fusing vertebrae and stabilizing sacro-iliac joints of a subject, comprising:
- a fusion cage sized and configured to be at least partially implanted between an S1 vertebra and an L5 vertebra;
- a first SI joint stabilizing member;
- and
- a second SI joint stabilizing member, wherein
- the fusion cage comprising,
- a first SI joint stabilizing member interface in an anterior portion and in a first lateral portion of the fusion cage,
- the first SI joint stabilizing member interface having at least one surface sized and configured to stably interface with a cage end region of the first SI joint stabilizing member when the first SI joint stabilizing member extends posterior, caudal and lateral relative to the fusion cage such that an ilium end of the first SI joint stabilizing member is implanted in a first ilium of the patient, and
- a second SI joint stabilizing member interface in an anterior portion and a second lateral portion of the fusion cage,
- the second SI joint stabilizing member interface having at least one surface sized and configured to stably interface with a cage end region of the second SI joint stabilizing member when the second SI joint stabilizing member extends posterior, caudal and lateral relative to the fusion cage such that an ilium end of the second SI joint stabilizing member is implanted in a second ilium of the patient.
6 more elements
A fusion cage that is adapted for SI joint stabilization, comprising:
- a body sized and configured to be at least partially implanted between an S1 vertebra and an L5 vertebra, the body including,
- a first SI joint stabilizing member interface in an anterior portion and in a first lateral portion of the fusion cage, and
- the first SI joint stabilizing member interface having at least one surface sized and configured to stably interface with a cage end region of a first SI joint stabilizing member when the first SI joint stabilizing member extends posterior, caudal and lateral relative to the body such that an ilium end of the first SI joint stabilizing member is implanted in a first ilium of the patient,
- a second SI joint stabilizing member interface in the anterior portion and in a second lateral portion of the fusion cage, and
- the second SI joint stabilizing member interface having at least one surface sized and configured to stably interface with a cage end region of a second SI joint stabilizing member when the second SI joint stabilizing member extends posterior, caudal and lateral relative to the body such that an ilium end of the second SI joint stabilizing member is implanted in a second ilium of the patient.
