Publication number: 20170290596Abstract: An apparatus for removing bone material including a distal cutting instrument and a proximal cutting instrument. The distal cutting instrument has at least one first cutting edge, a shoulder, and a shaft portion. The shaft portion has an anti-rotation feature. The at least one first cutting edge removes bone material when moved in a first direction. The proximal cutting instrument is removably attached to the shaft portion, and has a first end portion and a second end portion. The second end portion contacts the shoulder of the distal reamer when the proximal reamer is mounted to the shaft portion. The proximal reamer has at least one second cutting edge and an aperture. The aperture is adapted to receive the anti-rotation feature of the shaft portion of the distal reamer. The at least one second cutting edge removes bone material when moved in a second direction.Type: ApplicationFiled: June 26, 2017Publication date: October 12, 2017Inventors: David C. Kelman, Terry W.

Patent number: 8277728Abstract: A pre-assembled orthopaedic implant adapted for improved gas sterilization. The implant includes a first component adapted for assembly with a second component such that a mating surface of the first component is in close proximity with a mating surface of the second component. At least one gas conduit associated with the mating surface of the first component facilitates a sterilizing gas to penetrate into and dissipate from the interface defined by the mating surfaces.Type: GrantFiled: September 19, 2011Date of Patent: October 2, 2012Assignee: Smith & Nephew, Inc.Inventors: Richard D. Lambert, Terry W. McLean, David B. Vogel

Patent number: 8177788Abstract: Embodiments of the present invention provide a milling system and method that provides a precise triangular cut in a patient's proximal femur. The system allows the surgeon to mill in a single direction, that is, the drill is in the same or similar longitudinal place as the handle of the milling system, preventing the surgeon from having to enter the patient's leg at two different angles. The present invention also provides a milling system that can be pre-assembled (e.g., on the back table by a nurse while the surgeon is preparing the site), which enables the milling to take place in one step.Type: GrantFiled: February 22, 2006Date of Patent: May 15, 2012Assignee: Smith & Nephew, Inc.Inventors: Terry W. McLean, David C. Kelman

Patent number: 8029571Abstract: Methods, systems and devices for preventing prosthetic articulating surfaces from separating from each other. A containment system according to one embodiment seeks to prevent an implant stem head from dislocating from a prosthetic component while providing an increased range of motion over conventional constrained components. In one embodiment, an implant structural member includes a cavity and an opening having a lip, including a web along a portion of the lip. An implant stem head has a cooperating surface that corresponds with the web, so that when the cooperating surface of the implant stem head is aligned with the web, the head may be inserted into the implant structural member. The implant stem head is then rotated and the femoral stem component attached, thereby preventing dislocation of the head.Type: GrantFiled: May 28, 2010Date of Patent: October 4, 2011Assignee: Smith & Nephew, Inc.Inventor: Terry W. McLean
