Publication number: 20220273452Abstract: A total ankle replacement prosthesis may comprise a tibial implant, a talar implant, and an intermediate implant. The intermediate implant may fixedly attach to the tibial implant and may articulate with respect to the talar implant. The intermediate implant may have unequal front and back angular extent, so as to discourage a particular direction of subluxation, and a kit may be provided containing various such intermediate implants. Various features may be provided in regard to dovetails, fins, recesses, the placement of fins and pegs, and the shape of the perimeter of the tibial implant. Recesses may allow a surgical blade to slice a latch off of an already-installed intermediate implant, in order to allow its removal from the tibial implant.Type: ApplicationFiled: May 23, 2022Publication date: September 1, 2022Applicants: Smith & Nephew, Inc., Smith & Nephew Orthopaedics AG, Smith & Nephew Asia Pacific Pte. LimitedInventors: Lance Terrill, Shawn Roman, Timothy R. Daniels, Christopher F. Hyer, Selene G. Parekh, David I. Pedowitz

Publication number: 20070255419Abstract: In one embodiment of the present invention a prosthesis including a mechanism for attaching a first component to a second component is provided. In one example (which example is intended to be illustrative and not restrictive), the first component may be a femoral head component and the second component may be a femoral stem component. In another example (which example is intended to be illustrative and not restrictive), the femoral head component may comprise a ceramic material and the femoral stem component may comprise a metallic material (e.g., any desired orthopedic alloy, such as Cobalt Chromium).Type: ApplicationFiled: May 21, 2007Publication date: November 1, 2007Inventor: Lance Terrill

Publication number: 20040147932Abstract: The present invention is directed to a method for repair defects in articular cartilage, and, more particularly, to a new method for performing automated microfracture surgery on subchondral bone to repair articular cartilage. The microfractured holes on the surface of the subchondral bone are formed with an automated process using a pneumatically driven orthopedic microfracture instrument. The instrument moves a fracture pin through the end of a guide tube until a sharp end of the fracture pin punctures or penetrates the subchondral bone plate and creates a microfracture or hole in the bone.Type: ApplicationFiled: October 30, 2003Publication date: July 29, 2004Inventors: Brian Burkinshaw, Lance Terrill
