Abstract
Syndesmotic fixation devices, systems, instruments, and methods thereof. An implant for stabilizing an ankle joint between a tibia and a fibula may include first and second anchors secured to the tibia and a suture configured to wrap around the fibula. The suture may be tensioned to provide a circumferential force around the fibula to stabilize the joint.
Claims12
An implant for stabilizing a joint between a tibia and a fibula, the implant comprising:
- a first anchor configured to be inserted into a posterior aspect of the tibia, the first anchor including a cannulated body having a channel extending from a first end of the cannulated body to a second end of the cannulated body, wherein the first end includes a recess configured to receive and engage a cannulated driver instrument having a handle and a central longitudinal suture channel in communication with the channel of the cannulated body, wherein the second end includes an integrated distal tip that is rounded and blunt and the second end includes a first buckle having a first opening and a second opening, wherein the second opening is in fluid communication with the recess via the channel;
- a second anchor configured to be inserted into an anterior aspect of the tibia;
- and
- a suture extending from a first end to a second end and configured to wrap around the fibula, the first end of the suture securable by the first anchor and the second end of the suture securable by the second anchor, wherein the suture is tensioned by the cannulated driver instrument to provide a circumferential force around the fibula, thereby stabilizing the joint, the suture configured to pass through the central longitudinal suture channel of the cannulated driver instrument and the channel of the cannulated body,
- wherein the second anchor includes an assembly including a washer with an integrated buckle and a bone screw configured to be positioned through the washer,
- wherein the first opening and the second opening are longitudinally spaced apart from one another in a longitudinal axis of the first anchor,
- wherein the first opening and second opening are separated by an extension of the first anchor, and
- wherein the first opening and the second opening receive the suture through the cannulated body of the first anchor,
- wherein the integrated buckle protrudes at an angle from a plane of the washer, and
- wherein the integrated buckle includes a cross-member positioned between two side members and an upper member above the cross-member such that a third opening and a fourth opening are on opposite sides of the cross-member, and wherein the side members extend obliquely from the plane of the washer.

An implant system for stabilizing a joint between a tibia and a fibula, the implant system comprising:
- a cannulated driver instrument having a handle and a through opening defining a central longitudinal suture channel;
- a first anchor configured to be inserted into one side of the tibia, the first anchor including a cannulated body having a channel extending from a first end to a second end, wherein the first end includes a recess configured to receive and engage a distal end of the cannulated driver instrument, wherein the second end includes a first buckle having a first opening and a second opening longitudinally separated from each other, wherein the channel of the cannulated body and the recess are in fluid communication with the central longitudinal suture channel while the cannulated driver instrument is engaged with a drive feature of the cannulated body;
- a second anchor configured to be inserted into another side of the tibia, wherein the second anchor includes an assembly including a washer with an integrated buckle and a bone screw configured to be positioned through the washer, wherein the integrated buckle includes a cross-member positioned between two side members and an upper member above the cross-member such that a third opening and a fourth opening are on opposite sides of the cross-member, and wherein the side members extend obliquely from a plane of the washer;
- and
- a suture extending from a first end to a second end and configured to wrap around the fibula, the first end of the suture securable by the first anchor and the second end of the suture securable by the second anchor, wherein the suture is tensioned by the cannulated driver instrument to provide a circumferential force around the fibula, thereby stabilizing the joint, and the suture is configured to pass through the central longitudinal suture channel of the cannulated driver instrument and the channel of the cannulated body while the first anchor is being inserted into the tibia,
- wherein the first opening and the second opening receive the suture through the cannulated body of the first anchor.
