Abstract: Embodiments of knotless button-suture assemblies for orthopedic stabilization are disclosed. The button-suture assembly includes a button having a first opening, a second opening and a center opening. The assembly further includes a tensioning member having two tensioning member ends exiting from the first opening and the second opening of the button and disposed in the proximal direction. The assembly further includes a locking pin mated with the button through the center opening of the button in such a manner that allows a proximal movement of the tensioning member when a pulling force is applied to the tensioning member ends towards a proximal direction and prevents a distal movement of the tensioning member when the pulling force applied to the loose ends of the tensioning member ceases to exist.
Abstract: A knotless anchor assembly method and device comprising an anchor and a compression member, wherein the anchor further comprises a pilot tip and anchor body. During procedures to tension the knotless anchor assembly, the anchor is driven into bone or other surface or component, and the tension member is urged into the anchor body recess. The compression member is secured in the anchor body to lock the tension member in place. The knotless anchor assembly gives the surgeon or user the ability to optimize tensioning by having the ability to change tension in the tension member by adjusting the compression member during or after the repair.
Abstract: Button-suture assemblies which employ a knotted locking mechanism do not maintain tension when securing bone and tissue fragments. A knotless method and device for maintaining tension and providing precise placement of a button-suture assembly during stabilization procedures comprising a locking pin, which mates with a button creating pinch points with increased surface area through which suture can pass from a baseplate through two dedicated openings in the button, one for the first end of the suture and one for the second end of the suture while preventing tension loss during the locking step and therefore allowing for precise placement of the button-suture assembly.
