Publication number: 20250041069Abstract: Total ankle replacement (TAR) requires fixation of the tibial component to the tibia of a patient. and further requires fixation of the talar component to the talar of the patient. Disclosed herein are prosthetic implants that provide a high retention force to aid in preventing loosening after initial implantation. The prosthetic implant includes an expanding peg or post that allows the surgeon to expand the peg intraoperatively to apply radial pressure resulting in a wedged press fit that provides enhanced time zero fixation. As such. the present disclosure provides multiple fixation methods that allow for increased fixation during initial implantation of both the tibial and talar components in TAR surgery by providing dynamic compression between the prosthetic implant and the mating bone so that the prosthetic implant does not move or migrate after implantation.Type: ApplicationFiled: December 2, 2022Publication date: February 6, 2025Inventors: Adam N. Garlock, Chris Powell, Braham Dhillon, Maris Prieditis, Benjamin Chan

Patent number: 10016269Abstract: A buckle useful for cortical fixation has a graft retention loop slidably affixed thereto for movement from a first position adjacent a first end of the buckle to a second position at about the midpoint of the buckle. The buckle, with a graft over the loop, is drawn up lengthwise through a bone tunnel through a tibia and then flipped sideways to rest against the surface of the bone with the loop and graft depending back into the tunnel. The sliding attachment of the loop permits flipping of the buckle minimizes the flipping distance, which is the excess amount of the loop which must be pulled free of the tunnel to allow the buckle to be flipped sideways.Type: GrantFiled: September 12, 2016Date of Patent: July 10, 2018Assignee: DEPUY MITEK, LLCInventors: David B.
