US Patent:

7604666, Oct 20, 2009

Filed:

Jul 19, 2007

Appl. No.:

11/780370

Inventors:

Brian K. Berelsman - Warsaw IN, US
Kevin T. Stone - Winona Lake IN, US
Thomas J. Graham - Lutherville MD, US
Hill Hastins - Zionsville IN, US

Assignee:

Biomet Manufacturing Corp. - Warsaw IN

International Classification:

A61F 2/38

US Classification:

623 2012, 623 2011, 623 2013

Abstract:

A prosthetic joint kit, particularly well suited for an elbow, transmits load through the prosthetic joint through a pair of spherically shaped bearing surfaces so as to transmit load over a relatively large area rather than at a point or over a line of contact. The prosthetic joint kit may be configured in a modular manner wherein a plurality of interchangeable stem structures, bearing structures and/or bearing inserts of various types are available. Construction in this manner enables a surgeon to configure the prosthetic joint to best suit the needs of the patient. For example, the surgeon may employ a modular flange for compressing a bone graft, a tissue fastener for securing soft tissue to a portion of the prosthetic joint, a cam for limiting the amount by which the prosthetic joint articulates or a bearing insert for tailoring the degree of varus/valgus constraint.

International Classification:

A61F 2/42

US Classification:

623 2114, 623 2112

Abstract:

A prosthetic wrist having at least one of a radial insert, which is configured to be fixed to a radius of a patient, a carpal implant and a wrist bearing component. The carpal implant includes a body and a pair of flanges, each of which being skewed to the axis of the body in a manner that permits them to abut the ulnar side of the hamate bone and the radial side of the distal portion of the carpal bone complex, respectively. The radial insert may be provided with a plurality of modular portions to allow for selection and customization of an implant.

US Classification:

623 2112

Abstract:

A wrist prosthesis system to replace at least a portion of a bone of a wrist of a patient. The system includes a carpal implant to replace at least a portion of a carpal bone of a carpal complex of the patient. The carpal implant includes a base and an augment that replaces at least a portion of the carpal bone. The augment is removably coupled to the base.

International Classification:

A61F 2/38

US Classification:

623 2011

Abstract:

A modular prosthesis system for replacement of a head portion of a proximal radius includes a monolithic stem component, a head component, and a locking mechanism formed by the stem and head components. The stem component defines a stem anchoring portion having a longitudinal axis and configured to couple to the proximal radius, and a dovetail-shaped first mounting portion on a first end face that extends in a first direction transverse to the longitudinal axis. The head component has a dovetail-shaped second mounting portion on a second end face opposite the first end face slidably engaged with the first mounting portion along the first direction. One of the first and second mounting portions intersects the longitudinal axis. The locking mechanism is formed at an interface between the stem and head components and is engaged through relative translational movement between the stem and head components. A related method is provided.

International Classification:

A61F 2/38

US Classification:

623 2011, 606 62

Abstract:

A modular prosthesis system for replacement of a head portion of a radius. The prosthesis system includes a head component having a first connection portion that connects to a second connection portion and a collar component having the second connection portion and a third connection portion. The system also includes a stem component including a fourth connection portion that connects with the third connection portion, the stem component having a stem anchoring portion that connects to the radius. The collar component provides the modular geometry to the prosthesis without having to have an increased number of head components and stem components with variable lengths and angles.
