Patent number: 8523869Abstract: A system for preparing a trochlear region of a resected femur is disclosed. The system includes a reamer guide and a reamer. The reamer guide has a first arcuate portion, a second arcuate portion, a wall, a protrusion connected to the wall, a leg connected to one of the first or second arcuate portion, and a distal tip portion connected to the leg. The reamer is adapted to rotatably connect to the distal tip portion, and the reamer has a first end portion, a second end portion, and one or more flutes.Type: GrantFiled: November 20, 2007Date of Patent: September 3, 2013Assignee: Smith & Nephew, Inc.Inventors: Christopher F.

Publication number: 20120065687Abstract: Vertebral rods are provided that have predetermined curvatures to support various sections of the spine. The vertebral rods include a first end that is attached to a lower region of the spine, and a second end that is attached to an upper region of the spine. The construction of the rod results in a change in stiffness along the length between the first and second ends. The rods may also include predetermined curvatures to support various sections of the spine. The rods may include two of more longitudinal sections with different radii of curvatures to accommodate attachment to the various regions of the spine. The rods may also include one or more substantially straight sections. The rods may include a length to extend along a limited portion of the spine, or may extend along a majority of the spine. Further, the rods include a varying stiffness along the length.Type: ApplicationFiled: September 10, 2010Publication date: March 15, 2012Applicant: Warsaw Orthopedic, Inc.Inventors: Rodney R. Ballard, Julien J. Prevost, Christopher F. Scifert

Publication number: 20110184412Abstract: Surgical constructs pre-assembled for insertion as a unit into a patient. The construct may include an elongated member with opposing first and second ends and a non-circular cross-sectional shape. Connectors may be positioned on the elongated member and may include a first receptacle that receives the elongated member and a second receptacle spaced away from the first receptacle that receives a structural member in the patient. The first receptacles may be smaller than the elongated member to prevent the connectors from completely rotating around the elongated member. The construct may also include retaining members attached to the first and second ends of the elongated member. The retaining members may extend radially outward beyond the elongated member and may be larger than the first receptacles to prevent the connectors from escaping from the elongated member. Methods of assembling a construct prior to insertion into a patient are also disclosed.Type: ApplicationFiled: January 28, 2010Publication date: July 28, 2011Applicant: WARSAW ORTHOPEDIC, INC.Inventors: Christopher F Scifert, Ian Rubin de la Borbolla

Publication number: 20110106162Abstract: Elongated connecting elements include bodies having composite cross-sections defined by a center core that is surrounded by an outer portion. The center core includes a first material and the outer portion includes a second material that is distinct from the first material. In one particular form, a connecting element includes a maximum dimension across an outer cross-sectional shape of the outer portion that is less than a minimum dimension across an oblong or round outer cross-sectional shape of a polyetheretherketone (PEEK) connecting element, and the connecting element exhibits mechanical properties that are at least equivalent to the mechanical properties of the polyetheretherketone (PEEK) connecting element. In another form, the center core has a non-circular cross-sectional shape and the first material is defined by a reinforcing material randomly dispersed throughout a polymer, and the outer portion includes a circular, outer cross-sectional shape.Type: ApplicationFiled: October 30, 2009Publication date: May 5, 2011Applicant: Warsaw Orthopedic, Inc.Inventors: Rodney R.
