Filed:

Jan 18, 2002

Appl. No.:

10/051341

Inventors:

James R. Rogers - Winona Lake IN
Joel C. Rhoades - Pierceton IN
Troy D. Martin - Pierceton IN

Assignee:

DePuy Orthopaedics, Inc. - Warsaw IN

International Classification:

A61F 228

US Classification:

623 2347, 623 2345

Abstract:

A long bone prosthesis includes upper and lower articulating components, with the free ends of the components configured to engage a corresponding prosthetic joint. The overall length of the articulating components is adjustable to approximate the length of a patients long bone, such as the humerus. The articulating components include a stem and collet arrangement for fixing the relative axial and rotational position of the components. A tapered lock nut is threaded onto the outer threaded surface of the collet portion to provide a pressure engagement of the articulating elements. Various surface features can be implemented among the components of the prosthesis to enhance the pressure fixation, restrict rotation or provide indexed movement of the articulating components relative to each other.

International Classification:

A61F 2/36

US Classification:

623 2315, 623 2347

Abstract:

A system and method for trialing a modular hip replacement system permits evaluation and replication of the anatomic anteversion rotational angle of the femur. In one embodiment, a femoral hip implant kit includes at least one distal implant and a plurality of femoral heads, each of the plurality of femoral heads having a diameter different from the diameter of the other of the plurality of femoral heads. The kit includes a proximal trial housing with a bore within the housing, the bore configured to receive a portion of the distal implant, a collet located within the bore, the collet including an outer wall portion extending between a top surface portion and a bottom surface portion, a collapsing member for engaging the portion of the distal implant and for forcing the top surface portion of the collet toward the bottom surface portion of the collet along a first axis.

International Classification:

A61F 2/00
A61F 2/42

US Classification:

606 99, 623 2212

Abstract:

An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis. The tool includes a housing defining a housing longitudinal axis thereof. An internal component is also provided and is connected to the second component and includes an actuating device and an actuator rod defining a second longitudinal axis that is coexistent with the housing longitudinal axis. The internal component is adapted to provide relative motion of the internal component with respect to the housing when the actuating device is moved relative to the housing in at least a direction transverse to the housing longitudinal axis and the actuator rod of the internal component is moved relative to the housing in a direction parallel to the housing longitudinal axis.

US Classification:

606 86 R

Abstract:

A kit for use in joint arthroplasty that includes a first component of a prosthesis, a second component of the prosthesis, and an assembly tool for assembling the first component to the second component. The tool includes a housing for contact with the first component and an internal component connected to the second component. The internal component includes an actuating device and an actuator rod. The actuating device has at least one scissor arm. The housing and the internal component are adapted to provide for the assembly of the first component of the prosthesis to the second component of the prosthesis. The internal component is adapted to provide relative motion of the internal component with respect to the housing when the at least one scissor arm is moved relative to the housing, the relative motion of the internal component with respect to the housing being utilized to effect the relative motion of the first component with respect to the second component to urge the second component into engagement with the first component.
