Patent number: 9549826Abstract: A sigmoid notch resurfacing prosthesis for application to the sigmoid notch of the distal radius. The sigmoid notch prosthesis generally includes a saddle and a radius portion for attachment to the distal radius. The saddle may be formed from ultra high molecular weight polyethylene or another durable self-lubricating material. The saddle includes an at least partially concave contoured depression having rounded edges that is securable to the radius portion. The saddle may be secured by a sliding notch snap fit design. The prosthesis may be adapted for articulation with the natural head of the ulna or with an ulnar head prosthesis that has replaced the ulnar head.Type: GrantFiled: June 20, 2012Date of Patent: January 24, 2017Assignee: Mayo Foundation for Medical Research and EducationInventors: William P. Cooney, III, Richard A. Berger, David A. Leibel

Patent number: 9233004Abstract: A wrist implant requires minimal resection of the distal radius and preserves the sigmoid notch and articulation with the head of the distal ulna. The wrist implant generally includes a radius portion, a carpal portion and a carpal ball. The wrist implant includes a primary articulation and a secondary rotational articulation. The primary articulation occurs between the radius portion and the carpal ball. The secondary articulation occurs between the carpal ball and the carpal portion.Type: GrantFiled: June 5, 2014Date of Patent: January 12, 2016Assignee: Howmedica Osteonics Corp.Inventors: Amitava Gupta, David A.

Patent number: 9078758Abstract: An implant for carpal hemiarthroplasty includes an articular component having a convex articular surface shaped to generally conform to an unresected distal end of a radius bone. A bearing component is rigidly fixed to the articular component opposite the convex articular surface and has a bearing surface. A carpal plate is rotatably attachable to the bearing component and has a proximal surface and a distal surface. The proximal surface has a contour that substantially conforms to the bearing surface.Type: GrantFiled: May 10, 2012Date of Patent: July 14, 2015Assignee: Howmedica Osteonics Corp.Inventor: David A.
