Appl. No.:

10/333140

Inventors:

Thomas J Graham - Cockeysville MD, US
Brian K Berelsman - Warsaw IN, US
Hill Hastings - Zionsville IN, US
Kevin T Stone - Winona Lake IN, US

Assignee:

Biomet Manufacturing Corp. - Warsaw IN

International Classification:

A61F 2/38

US Classification:

623 2013

Abstract:

A prosthetic joint kit that is particularly well suited for an elbow. In each of the various embodiments, the prosthetic joint kit 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, being 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.

Abstract:

A jig for positioning an implant at an implantation site in a bone. The jig comprises a first end, a second end opposite the first end, an exterior surface, an interior surface operable to receive at least a portion of the implant, and an engagement surface located at the second end to permit positioning of the jig in the bone. The jig is anchored to the bone to secure the implant in proper position at the implantation site.

International Classification:

A61F 2/40

US Classification:

623 1911, 623 1913

Abstract:

A glenoid component used for shoulder arthroplasty is adapted to be implanted into a scapula and engaged by a head of a humeral component. The glenoid component includes a body having a first articulating surface and a second medial surface opposite to the first articulating surface. The first articulating surface is adapted to engage with a humeral head. A plurality of fixed pegs each have a first end adapted to engage a cavity formed in the scapula and a second end extending from the medial surface. A central peg fixation mechanism is provided that is configured to couple an optional central fixation peg to the medial surface.
