Appl. No.:

13/570311

Inventors:

David J. Neal - Morris Plains NJ, US
Jorge Montoya - Madison NJ, US
John Chernosky - Brick NJ, US
Ray Zubok - Midland Park NJ, US
Keith A. Roby - Jersey City NJ, US

Assignee:

Zimmer, Inc. - Warsaw IN

International Classification:

A61B 17/17

US Classification:

606 79, 606 88

Abstract:

A conical burr template is indexed to the intramedullary canal of a tibia, such that a burr may trace the periphery of the template to define a correspondingly shaped cavity in the bone which is properly sized, shaped, and positioned to receive a cone-shaped tibial augment component. Advantageously, use of the burr template promotes expedient surgery while maintaining optimal fit characteristics and proper spatial placement of the tibial cone augment.

International Classification:

A61B 17/68

US Classification:

606151

Abstract:

The present disclosure relates, in some aspects, to orthopaedic implants for securing soft tissue to bone and methods for using the same. One particular implant comprises a first exposed porous surface region, having pores for promoting bone ingrowth, and a second exposed porous surface, having pores for promoting soft tissue ingrowth. At least some of the pores of the first exposed porous surface region may be seeded with osteocytic factors and at least some of the pores of the second exposed porous surface region may be seeded with fibrocytic factors. Such orthopaedic implants can advantageously facilitate regeneration of the soft tissue to bone interface.

International Classification:

A61B 17/74

US Classification:

606281, 606286, 606292, 606289

Abstract:

A trochanter attachment device can include a plate for attachment to an inner portion of a greater trochanter of a femur, a collar for attaching the plate to a hip implant, and a fastener for securing the collar to a hip implant. The trochanter attachment device can include a groove or other feature for receiving a reinforcing material, such as a wire or a cable, such as to reinforce an attachment of the device to the greater trochanter and/or the hip implant. The trochanter attachment device can include an insert attachable to the plate and configured to attach the plate to the greater trochanter. All or a portion of the plate and/or the insert can include a porous material, such as to promote bone ingrowth of the greater trochanter.

International Classification:

A61F 2/38

US Classification:

623 2032

Abstract:

A tibial support structure includes a platform portion and a medullary portion that are monolithically formed as a single piece. The medullary and platform portions of the augment component are adapted to accommodate and mechanically attach to a tibial baseplate, and are individually shaped and sized to replace damaged bone stock both within the tibia, as well at the tibial proximal surface. The monolithic formation of the tibial support structure provides a strong and stable foundation for a tibial baseplate and facilitates restoration of the anatomic joint line, even where substantial resections of the proximal tibia have been made. The tibial support structure may be made of a bone-ingrowth material which facilitates preservation and rebuilding of the proximal tibia after implantation, while also preserving the restored joint line by allowing revision surgeries to be performed without removal of the tibial support structure.

International Classification:

A61F 2/38

Abstract:

Fastener systems and methods for attaching two or more parts are disclosed. A fastener can include a nut component configured to extend into at least a portion of an aperture in a first part and at least a portion of an aperture in a second part. The fastener can further include a compression body configured to fit into an enlarged portion of the aperture in the second part, and a screw component having a head portion configured to engage with a top notch formed in the compression body and an elongated portion configured to engage with the nut component. A diameter of the head portion of the screw component can be less than a diameter of the top notch in the compression body such that the screw component can move in a radial direction relative to the compression body during placement of the fastener to attach two or more parts.
