Publication number: 20150066149Abstract: A modular humeral head resurfacing implant including a head, an anchoring stem, and a modular extended articulation flange. The head includes an exterior hemispherical articulating surface defining a terminating rim, an interior concave surface opposite to the exterior articulating surface, and a first coupling mechanism proximate to the terminating rim. The anchoring stem is coupled to the interior concave surface and extends along a stem axis that extends through an axial center of the head. The articulation flange includes a second coupling mechanism configured to cooperate with the first coupling mechanism to fasten the articulation flange to the head and an outer articulating surface that is curved along substantially its entire length and is substantially flush with the exterior hemispherical articulating surface when the articulation flange is fastened to the head.Type: ApplicationFiled: November 12, 2014Publication date: March 5, 2015Inventors: Russell Parrott, Nathan A.

Patent number: 8292967Abstract: A prosthesis includes an implant defining an attachment surface thereon. A porous insert is selectively coupled to the implant. The porous insert is adapted to be received at the attachment surface of the implant in a retained position. The porous insert is adapted to facilitate tissue ingrowth. In one embodiment the implant comprises a femoral component. The femoral component comprises an inner condylar portion having a first and second lateral sidewalls, an anterior wall and a posterior wall defining a box. The box defines the attachment surface. In other embodiments, the implant comprises a hip stem and an acetabular shell.Type: GrantFiled: December 5, 2005Date of Patent: October 23, 2012Assignee: Biomet Manufacturing Corp.Inventors: David R Brown, Brian May, Jennifer Woodell-May, Jacy C Hoeppner, Elizabeth Schlueter, Mukesh Kumar, John R White, Russell Parrott

Publication number: 20070038302Abstract: A glenoid component for use in shoulder arthroplasty, the glenoid component is adapted to be implanted into a scapula and engaged by a head of a humeral component. The glenoid component has a body with an exterior periphery which is supported by surrounding bone. The glenoid component further has a bearing surface that is congruent with the natural bearing surface of the adjacent bone. A method of implantation of a glenoid prosthesis is further provided which reduces the damage to adjacent soft tissue materials.Type: ApplicationFiled: August 15, 2005Publication date: February 15, 2007Applicant: Biomet Manufacturing Corp.Inventors: Jason Shultz, Brian Berelsman, Russell Parrott, Nathan Winslow

Publication number: 20060173546Abstract: A method and apparatus for replacing a selected portion of the anatomy is described. In particular, a prosthesis can be provided to replace a portion of an articulating joint, such as an elbow. The apparatus can be modular for various reasons and each of the modular portions can include a different dimension to achieve a selected result. For example, the prosthesis can achieve a different size condylar replacement, a selected offset, a selected articulation, or combinations thereof.Type: ApplicationFiled: March 17, 2006Publication date: August 3, 2006Applicant: Biomet Manufacturing Corp.Inventors: Brian Berelsman, Kevin Stone, Russell Parrott, Hill Hastings, Thomas Graham

Publication number: 20050075735Abstract: 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.Type: ApplicationFiled: November 29, 2004Publication date: April 7, 2005Inventors: Brian Berelsman, Russell Parrott, Christopher Martin
