Patent number: 7198628Abstract: An adjustable humeral cutting guide for defining a cutting plane for a saw in a bone using a positioning structure includes a clamp, a saw guide, and an orientable coupling. The clamp is configured to be secured to the positioning structure. The saw guide includes a slot formed therein and formed to cooperate with a saw and limit the saw to cutting in a specific plane. The orientable coupling is mounted to the clamp and the saw guide. The orientable coupling is configured to adjust the saw guide at a selectable anterior/posterior angle and a selectable medial/lateral angle.Type: GrantFiled: June 30, 2004Date of Patent: April 3, 2007Assignee: DePuy Products, Inc.Inventors: Jeffrey M. Ondrla, Andrea Hahn, Gerald Ross Williams, Jr.

Patent number: 7160328Abstract: A medical procedure includes providing a prosthesis which includes (i) a body portion having a rear surface and a bearing surface, and (ii) an anchor peg including a shaft extending from the rear surface of the body portion, wherein the anchor peg includes a plurality of outwardly extending fins secured to the shaft, and further wherein the plurality of outwardly extending fins each possesses a first diameter. The medical procedure further includes creating an anchor hole in a natural bone, the anchor hole possessing a second diameter which is less than the first diameter. In addition, the method procedure includes positioning the anchor peg within the anchor hole so that each of the plurality of outwardly extending fins deforms so as to possess (i) a concave side which faces an open end of the anchor hole, and (ii) a convex side that faces a closed end of the anchor hole.Type: GrantFiled: May 16, 2005Date of Patent: January 9, 2007Assignee: DePuty Products, Inc.Inventors: Charles A. Rockwood, Jr., Michael A. Wirth, Thomas S. Camino, Jack F. Long, Jeffrey M. Ondrla

Patent number: 7044973Abstract: A shoulder prosthesis of the present invention includes a modular humeral prosthesis component employing a collarless design. A body portion of the prosthesis is provided without a collar, and it may be implanted into a prepared proximal end of a humerus such that the body sits recessed below the level of the cut proximal surface of the humerus. A head portion is provided in which a support surface of the head functions as collar by direct apposition of it to the cut proximal humerus. The modular connection is thus recessed below the proximal bone surface. By providing a modular connection which is recessed below the bone surface, the benefits of modularity may be retained, while joint overstuffing may be reduced or eliminated, and a substantially full range of motion may be achieved.Type: GrantFiled: January 3, 2003Date of Patent: May 16, 2006Assignee: DePuy Orthopaedics, Inc.Inventors: Charles A. Rockwood, Jr., Jeffrey M. Ondrla

Patent number: 7011686Abstract: A humeral component of a shoulder prosthesis includes a stem configured for implantation within the humerus. A reverse articulating component is mounted to the stem by a connection mechanism. The reverse component defines a substantially concave bearing surface. The bearing surface is part of a bearing member that is engaged to a support member that is associated with the connection mechanism. A kit is provided which includes differently configured bearing members and support members to allow intraoperative selection and assembly of an optimum articulating component.Type: GrantFiled: September 30, 2002Date of Patent: March 14, 2006Assignee: DePuy Products, Inc.Inventors: Robert J. Ball, Jeffrey M. Ondrla, Anne-Céline Godest

Patent number: 6986790Abstract: A humeral prosthesis allows a surgeon to adjust humeral head position thereof in three-dimensional space with respect to a humeral component of the humeral prosthesis that has been either previously implanted into a humerus of a patient or not. The humeral prosthesis includes a conjoining component that is configured to releasably mate with the humeral component and to releasably mate with a humeral head. The conjoining component allows the humeral head to be selectively positionable from continuously infinite positions about two orthographic axes with respect to the conjoining component. The selected spatial position of the head is locked by a locking member of the conjoining component. The conjoining component allows the use of various sized heads, allow in vivo head trialing and/or exchange, and retrofit of heads for previously implanted shoulder prosthesis in need of revision.Type: GrantFiled: September 30, 2002Date of Patent: January 17, 2006Assignee: DePuy Products, Inc.Inventors: Robert J. Ball, Jeffrey M. Ondrla

Patent number: 6863690Abstract: The humeral portion of a shoulder prosthesis includes a diaphyseal component configured for fixation within the humerus, a metaphyseal component, configured for removable implantation within the metaphysis of the humerus, and an engagement mechanism for removably engaging the two components. The metaphyseal component can initially include a convex articulating surface that can be replaced with a concave surface during the shoulder arthroplasty procedure or in a subsequent revision surgery. The metaphyseal component can also include a feature to facilitate removal of the component from the bone once it has been disengaged from the diaphyseal component.Type: GrantFiled: September 27, 2002Date of Patent: March 8, 2005Assignee: DePuy Products, Inc.Inventors: Robert J. Ball, Jeffrey M. Ondrla, Laurent LaFosse, Anne-Céline Godest
