Epicondylar Axis Alignment-Femoral Positioning Drill Guide
US Patent:
6096043, Aug 1, 2000
Filed:
Dec 18, 1998
Appl. No.:
9/216436
Inventors:
Richard C. Techiera - Avon MA
Arlen D. Hanssen - Rochester MN
Scott Presbrey - Slatersville RI
Arlen D. Hanssen - Rochester MN
Scott Presbrey - Slatersville RI
Assignee:
DePuy Orthopaedics, Inc. - Warsaw IN
International Classification:
A61B 1758
US Classification:
606 88
Abstract:
A tool lays out resection or alignment features to prepare a bone end for prosthetic joint replacement. The tool attaches to the end of the femur, and positions an initial cut, for example a pair of aligned drill holes for the positioning pins of a prosthesis or the cutting blocks used in preparing the distal femur. The tool includes adjustable assemblies coupled to a main body for setting its position, and these are arranged with graduations for sizing the femur. The adjustable assemblies include an epicondylar engaging assembly such as a pair of clamp arms which slide in the body to align the body along the epicondylar axis. It further includes one or more other assemblies which determine a line, offset depth or other coordinate or component of orientation to set the drill guide for optimally locating the initial cut in the femur. Preferably, the other assemblies include an A/P sizing jig in the tool which determines an offset, and the drill guide is coupled so that it positions drill holes on the bone end in coordination with sizing jig. The clamp assembly may further indicate medial/lateral offset information for shifting the center to improve tracking and alignment.

Acetabular Shell With Screw Access Channels
US Patent:
6709462, Mar 23, 2004
Filed:
Jan 11, 2002
Appl. No.:
10/044044
Inventors:
Arlen D. Hanssen - Rochester MN
Assignee:
Mayo Foundation for Medical Education and Research - Rochester MN
International Classification:
A61F 232
US Classification:
623 2235, 623 2234
Abstract:
An outer shell for a socket of a joint prosthesis is disclosed. The outer shell includes an outer wall defining an outer surface of the shell and an inner wall defining an inner surface of the shell. The outer wall has pores to permit bone tissue to grow into the outer wall, and the inner surface of the shell engages the socket. The inner wall has access channels suitable for seating a bone screw. The access channels are closed off by an associated integral section of the shell. Preferably, each access channel is closed off by a section of the outer wall so that the shell retains maximal outer surface area for bone tissue ingrowth. When a number of bone screws are needed for affixation of the shell to bone, a number of locations for bone screws can be created in the shell by opening the closed access channels.

International Classification:
A61F 2/38
US Classification:
623 2032
Abstract:
A tibial augment for use with a knee joint prosthesis, composed of annular members of different stock sizes, each size being configured to fit within a cavity formed in a human tibia. The augment may include a stepped distal surface. A provisional (temporary) tibial augment used to ensure a proper fit for the permanent augment is also provided. The provisional may include grooves configured to cooperate with a set of ribs on a tong-like holder used for removing the provisional from the cavity. A pusher for use implanting the tibial augment is also provided. In addition, a system for creating a cavity in a human tibia is also described. The system preferably includes a guide with a slot therein and a set of osteotomes that are inserted within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described.

Abstract:
A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of the cavity in the end of the bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the channel by an adhesive. The stem of the prosthesis beyond the channel may be cemented or uncemented. The support structure may have an approximately funnel shape. The support structure may be a hollow porous cylindrical sleeve. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining a channel between the pair of components. The support structure may comprise a plurality of pedestals secured to the inner surface of the cavity of the bone.
