Patent number: 10342665Abstract: An elbow prosthesis constructed in accordance to one example of the present teachings can include a capitellar implant having an articulating head and a stem. The articulating head can have a first articulating surface positioned generally between a lateral side and a medial side. A passage can extend through the articulating head from the lateral side to the medial side. The articulating head can define a counterbore formed at the lateral side and that is concentric with the passage. According to other features, the elbow prosthesis can include a coronoid implant that has a body and a stem. The body can have a superior articulating surface that includes a central ridge and an anterior buttress. The central ridge can be configured to accommodate articulation with a trochlea in an implanted position.Type: GrantFiled: February 3, 2017Date of Patent: July 9, 2019Assignee: Encore Medical, L.P.Inventors: Thomas J. Graham, Nicholas J. Katrana

Patent number: 10231839Abstract: 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: GrantFiled: February 24, 2009Date of Patent: March 19, 2019Assignee: Encore Medical, L.P.Inventors: Brian K.

Patent number: 10226350Abstract: A glenosphere includes a body, a first surface, and a cavity defined with the body. The body defines a center and an engagement axis, the engagement axis spaced by an offset from the center. The first surface includes a first rim positioned radially outward from a second rim, a base surface portion, and a hood surface portion extending from the base surface portion and oriented at an obtuse angle relative to the base surface portion. The body defines a hood portion extending from the hood surface portion to a plane including the base surface portion. The cavity has a perimeter defined by the second rim, and includes a first cavity portion configured to receive an attachment structure attachable to a bone, and a second cavity portion configured to engage an engagement member of the attachment structure and oriented along the engagement axis.Type: GrantFiled: September 6, 2016Date of Patent: March 12, 2019Assignee: ENCORE MEDICAL L.P.Inventors: Mark A. Frankle, Sergio Gutierrez, Gerald Williams

Patent number: 10226346Abstract: A joint prosthesis is provided and may include first and second stem structures and first and second bearing members. The first stem structure may include a generally U-shaped portion having first and second legs. The second stem structure may include first and second bearing surfaces. The first bearing member may be removably coupled to the first leg and may include a first laterally facing bearing surface rotatably contacting the first bearing surface. The second bearing member may be removably coupled to the second leg and may include a second laterally facing bearing surface rotatably contacting the second bearing surface. The first laterally facing bearing surface may be disposed between the first leg and a first lateral side of the second stem. The second laterally facing bearing surface may be disposed between the second leg and a second lateral side of the second stem. The second lateral side may oppose the first lateral side.Type: GrantFiled: March 21, 2014Date of Patent: March 12, 2019Assignee: Encore Medical, L.P.Inventors: Nicholas J. Katrana, Brian K.

Patent number: 9901453Abstract: An elbow prosthesis includes a stem structure and an articulating component. The stem structure is operable to be positioned in a bone of a joint and includes a stem portion and a C-shaped body portion. The stem portion is operable to be positioned in the bone. The C-shaped body portion includes a first articulating surface bound by a medial wall and a lateral wall. The medial and lateral walls are separated by a first distance. The articulating component includes a second articulating surface positioned between a medial side surface and a lateral side surface. The medial and lateral side surfaces are separated by a second distance that is less than the first distance. The second articulating surface is configured to slidably communicate in a medial/lateral direction along the first articulating surface of the C-shaped body portion.Type: GrantFiled: March 30, 2015Date of Patent: February 27, 2018Assignee: Encore Medical, L.P.Inventors: Nicholas J.

Publication number: 20080183298Abstract: A prosthetic femoral implant for use in a hip joint, as a ball and socket type joint, is disclosed. The implant includes a modular neck having a variety of adjustable positions to adjust the lateral offset and version angle of the femoral implant in relation to the femur. The implant further includes a broad, full collar for providing a compression force increasing the interdigitation between the interface of the bone, implant and cement. The implant also includes a stem having a depression having a roughened porous surface for resisting the increased torsional loads placed on the implant due to the increased lateral offset and version angle. The stem further comprises three distinct zones, each zone having its own roughened surface creating a tripartite differential porosity.Type: ApplicationFiled: January 29, 2008Publication date: July 31, 2008Applicant: ENCORE MEDICAL, L.P.Inventors: Timothy MCTIGHE, Ian MURRAY, Hugh U.
