Apparatuses and methods for fixation of ankle syndesmosis or acromioclavicular joint dislocations of the shoulder
A method of ankle syndesmosis repair according to an exemplary aspect of the present disclosure includes, among other things, drilling a hole through a fibula and a tibia of an ankle joint, pulling a first button device through the hole using a pull-through suture until the first button device exits on a medial side of the tibia, flipping the first button device so it rests against a medial cortex of the tibia, and positioning a second button device at a lateral side of the fibula.
1. A method of ankle syndesmosis repair, comprising:
drilling a hole through a fibula and a tibia of an ankle joint using a single drill bit;
pulling a first button device through the hole using a pull-through suture until the first button device exits on a medial side of the tibia;
flipping the first button device so it rests against a medial cortex of the tibia; and
positioning a second button device at a lateral side of the fibula, wherein a flexible suture coupling is connected to the first button device and the second button device.
2. The method as recited in claim 1 , comprising reducing a fracture of the fibula prior to drilling the hole.
3. The method as recited in claim 1 , wherein pulling the first button device includes:
connecting the first button device to a suture passing instrument with the pull-through suture; and
inserting the suture passing instrument through the hole to advance the first button device horizontally through the hole.
4. The method as recited in claim 3 , wherein flipping the first button device includes:
applying traction to the pull-through suture while applying counter-traction to the flexible suture coupling connected to the first button device until the first button device pivots from a position generally parallel to the hole to a position generally transverse to the hole.
5. The method as recited in claim 1 , wherein the flexible suture coupling is double looped through the first button device and the second button device.
6. The method as recited in claim 1 , wherein positioning the second button device includes:
tightening down the second button device on the lateral side of the fibula by applying traction to a free end of the flexible suture coupling connected to each of the first button device and the second button device.
7. The method as recited in claim 1 , wherein the first button device and the second button device each include at least one aperture.
8. The method as recited in claim 1 , wherein pulling the first button device includes:
passing an elongated pull-through device that is connected to the pull-through suture through the hole.
9. The method as recited in claim 1 , comprising reducing a syndesmosis disruption prior to performing the drilling, pulling, flipping and positioning steps.
10. A method of ankle syndesmosis repair, comprising:
reducing a syndesmosis disruption of an ankle joint;
drilling a hole through a fibula and a tibia of the ankle joint using a single drill bit;
pulling, in a lateral-to-medial direction of the ankle joint, a first button device through the hole with a pull-through suture until the first button device exits on a medial side of the tibia;
flipping the first button device so it rests against a medial cortex of the tibia;
positioning a second button device at a lateral side of the fibula, wherein a flexible suture coupling is connected to the first button device and the second button device; and
tightening down the second button device on the lateral side of the fibula by applying traction to a free end of the flexible suture coupling.
