Abstract: A bone disunion instrument system may include a first bone pin, a second bone pin, and a guide block. The guide block may include first and second bone pin holes to receive the first and second bone pins, and a window intermediate the first and second bone pin holes. The first bone pin may be anchored in a first bone portion and inserted through the first bone pin hole, and the second bone pin may be anchored in a second bone portion and inserted through the second bone pin hole to impart a compression or distraction force on a bone disunion between the first and second bone portions. The window formed through the guide block may provide access for an implant placed through the window to stabilize the bone disunion while the bone disunion is placed under a compression or distraction force.

Abstract: A bone disunion fastener may include a fastener shaft, a helical thread, and a bone staple. The helical thread may include a concave undercut surface oriented towards one end of the fastener shaft. The bone staple may include a first bone-engaging feature, a second bone-engaging feature, and a middle portion with an opening. The bone disunion fastener may be implanted along a disunion between a first bone portion and a second bone portion. The concave undercut surface may be shaped to resist at least one force transmitted between the first bone portion and the second bone portion to stabilize the disunion. The first bone-engaging feature may engage the first bone portion and the second bone-engaging feature may engage the second bone portion to couple the bone staple to the bone portions and resist at least one force transmitted between the bone portions to stabilize the disunion.

Abstract: Drill guides are disclosed herein that include a tapered projection that hooks under a bone to position the drill guide relative to the bone. The drill guide is used to drill a hole that receives a suture anchor.
