CA PATENT 3002234     Sacroiliac Joint Fixation Fusion System

A system for fixating a sacroiliac joint that includes a sacroiliac joint implant for implantation in the sacroiliac joint. The sacroiliac joint implant includes an elongate body including a first end a second end and a length disposed between the first end and the second end. The elongate body is adapted to non-transversely locate within the sacroiliac joint. The system also includes a coupling element configured to connect to the sacroiliac joint implant. The system further includes a spanning member securable to the coupling element and a second coupling element engageable with the spanning member.

Il est décrit un système de fixation darticulation sacro-ilaque qui comprend un implant darticulation sacro-ilaque destiné à être implanté dans larticulation sacro-ilaque. Limplant darticulation sacro-ilaque comprend un corps allongé comprenant une première et une seconde extrémités, et une longueur disposée entre la première et la seconde extrémités. Le corps allongé est conçu pour se positionner de manière non transversale à lintérieur de larticulation sacro-ilaque. Le système comprend également un élément de couplage conçu pour se connecter à limplant darticulation sacro-ilaque. Le système comprend en outre un élément de recouvrement pouvant être fixé à lélément de couplage et au second élément de couplage ayant lélément de recouvrement.

CLAIMS

THE SUBJECT-MATTER OF THE INVENTION FOR WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED IS DEFINED AS FOLLOWS:

1. A system for fixating a sacroiliac joint, the system comprising:

a sacroiliac joint implant for implantation in the sacroiliac joint, the sacroiliac joint implant comprising an elongate body including a first end, a second end, a length disposed between the first end and the second end, and a rectilinear cross-section transverse to the length, the elongate body being adapted to non-transversely locate within the sacroiliac joint;

a first coupling element configured to connect to the sacroiliac joint implant;

a spanning member securable to the first coupling element; and

a second coupling element engageable with the spanning member.

2. The system as described in claim 1, wherein at least a portion of the spanning member is in the form of a plate, the portion configured with at least one aperture configured to allow passage of at least a part of the second coupling element.

3. The system as described in claim 2, wherein the second coupling element includes a fastener element configured to pass through an aperture and the fastener element is further configured to be disposed into bone of at least one of a sacrum and an ilium.

4. The system as described in any one of claims 1 to 3, wherein the system is configured to allow for coupling of a lumbar spine to a pelvis.

5. The system as described in any one of claims 1 to 3, wherein the system is configured to allow for coupling of a pair of sacroiliac joint implants.

6. The system as described in any one of claims 1 to 5, wherein at least two of the following form a unitary construction: the implant; the first coupling element; the second coupling element; and the spanning member.

7. The system as described in any one of claims 1 to 6, wherein the rectilinear cross- section comprises a cross-shaped cross-section.

8. The system as described in any one of claims 1 to 6, wherein the rectilinear cross- section comprises a triangular cross-section.
