Patent number: 7935118Abstract: A kit for removal of bone adjacent to an implanted prosthesis. The kit includes a guide for cooperation with the prosthesis and a tool constrainable by the guide for removal of the bone. The guide may include a first portion of the guide that is co-operable with the tool and a second portion of the guide that is co-operable with the prosthesis.Type: GrantFiled: June 21, 2002Date of Patent: May 3, 2011Assignee: DePuy Products, Inc.Inventors: Tim Vendrely, M.

Patent number: 5776200Abstract: The method of implanting a femoral and a tibial knee prosthesis and instruments for surgically implanting the femoral and tibial prosthesis component as disclosed. The method includes the formation of a plurality of surgical cuts on the patient's distal femur. A trial tibial prosthesis is then fitted to the surgically prepared distal femur. The trial prosthesis has a femoral articulating surface and a non-articulating surface that fits the patient's distal femur at the surgical cuts. A surgeon then forms a transverse cut on the patient's proximal tibia. The surgeon places a tibial trial prosthesis on the patient's proximal tibia, the trial prosthesis including a tibial trial stem that fits the patient's intramedullary canal, a tibial trial metallic tray or plate, and a plastic trial insert that fits the tibial tray or plate. The plastic insert includes a tibial articulating surface that can articulate with the femoral articulating surface.Type: GrantFiled: June 7, 1995Date of Patent: July 7, 1998Assignee: Smith & Nephew, Inc.Inventors: Chris E. Johnson, Tim Vendrely, Leo A. Whiteside, Thomas A. Carls, John Steele, Khosrow Naraghian

Patent number: 5702460Abstract: A trial femoral prosthesis for use in knee joint replacement surgery includes a trial prosthesis body that is generally J-shaped. The prosthesis body provides a distal articulating surface and a proximal non-articulating surface. The articulating surface includes medial and lateral condylar portions, a distal portion, and an anterior portion. An elongated stem extends from the distal non-articulating surface for anchoring the trial prosthesis to the intramedullary canal of the patient's femur. Wedge trial insert members are connectable to the trial prosthesis body at the non-articulating surface. The inserts can be of different shape and different thicknesses and can be independently placed on opposite sides of the stem. However, the prosthesis body can be used independently without any inserts. The apparatus assists a surgeon who is going to revise a total knee that had been previously implanted. If a surgeon needs a wedge insert for the trial, a corresponding wedge is placed on the final knee implant.Type: GrantFiled: August 16, 1995Date of Patent: December 30, 1997Assignee: Smith & Nephew, Inc.Inventors: Thomas A. Carls, Tony Melkent, Leo A. Whiteside, Tim Vendrely

Patent number: 5683397Abstract: A distal femoral cutting block apparatus for use in knee surgery includes an instrument body that has generally flat opposing parallel surfaces and a plurality flat peripheral surfaces to form a generally rectangular body. The body provides anterior and posterior surfaces and medial and lateral surfaces. The transverse slot carries a valgus module that is movably disposed in the slot. The valgus module includes a tubular sleeve member having a pair of opposed sides that abut the body at the slot. A portion of the tubular sleeve member is threaded and the threaded portion extends away from the body. An open ended bore extends through the tubular member. The open ended bore of the tubular sleeve member of the module accommodates an intramedullary rod that fits the patient s intramedullary canal. A lock nut engages the threaded section of the module for locking the module in a desired position on the cutting block body by engaging the threaded portion and the instrument body to rigidly affix them together.Type: GrantFiled: February 15, 1995Date of Patent: November 4, 1997Assignee: Smith & Nephew, Inc.Inventors: Tim Vendrely, Leo A.

Patent number: 5667511Abstract: A method of preparing a patient's proximal tibia with a surgical saw and cutting instrumentation is disclosed. The method of the present invention prepares the patient's proximal tibial to receive a tibial implant. The patient's intramedullary canal is first reamed and then an intramedullary rod is placed in the intramedullary canal as a reference. A first cutting instrument is bound on the rod above the patient's proximal tibia. The first cutting instrument includes a stylus that is used to set the depth of cut by referencing the top of the proximal tibia. The proximal tibia is then transversely cut with the saw by tracking the first cutting guide surfaces with the saw. The first cutting instrument is removed together with its stylus. A secondary cutting instrument is then placed on the rod above the proximal tibia. The second cutting instrument has a cutter at its center for cutting longitudinally into the proximal tibia.Type: GrantFiled: June 7, 1995Date of Patent: September 16, 1997Assignee: Smith & Nephew Richards Inc.Inventors: Tim Vendrely, Leo A. Whiteside, Thomas A. Tommy Carls, John Steele, Chris E. Johnson
