Abstract: Described herein are examples of orthopedic drill bits and methods of preparing a bone of a living being for fixation. An example method includes coupling a drive attachment of a drill bit to a mounting attachment of a driver, and placing a guide at a desired location on the bone. The guide has an opening corresponding to an area of bone to be removed. The guide provides proper positioning and alignment for drilling a hole. With the guide in place, the method further includes aligning the drill bit with the opening on the guide and drilling a hole in the bone. Once the hole is drilled, the method includes de-coupling the drill bit from the driver, and bending the drill bit at the drive attachment while the drill bit is still in the bone. In some examples, additional method steps follow preparation of the hole.

Abstract: Treatment devices for sacroiliac (SI) joint hypomobility are described herein. In one example, a method of treating SI joint hypomobility involves positioning a person relative to a SI joint device that includes a resilient crest. Positioning the person relative to the SI joint device can involve aligning the resilient crest along the SI joint underneath the person. The method can also include using the SI joint device to pry open the SI joint. In another example, an SI joint device includes a body extending between a medial end and a lateral end, and the body includes a rigid protrusion. The SI joint device can also include a resilient cover extending over the rigid protrusion. The rigid protrusion and the resilient cover can define a crest for prying open the SI joint. The crest can include a concavity oriented towards the lateral end of the body, and the crest can deform towards the lateral end of the body when subjected to a load on a top of the crest.

The second fastener is mounted to the second bone and a sliding knot, formed in the looped suture ends, is advanced into contact with the second fastener. The suture is further tensioned using a tensioner device to secure the two bones together.
