Patent number: 11969353Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.Type: GrantFiled: June 3, 2020Date of Patent: April 30, 2024Assignee: Zimmer, Inc.Inventors: Steven Humphrey, James D. Wernle, Joanna Surma, Stephen H. Hoag, Donald W. Dye, Kenton A. Walz, Terry W. Wagner, Kathleen Macke, Duane Gillard, Brian D. Byrd, Ken Yamaguchi

Patent number: 11376092Abstract: Various parallax-free indicator devices, systems, and methods are disclosed. The indicator device may have a housing defining an aperture and a light source assembly at least partially disposed in the housing. The housing may be selectively securable via a fastener to an instrument in a selected orientation relative to the instrument. The light source assembly may have a light source operably coupled to a power source via a power circuit. The light source may be positioned within the housing to emit through the housing aperture. Upon activation, the light source assembly emits a parallax-free alignment indicator along an alignment axis that may have at least one of a selected angle and a selected displacement relative to a selected reference axis. The alignment indicator may guide a surgical procedure.Type: GrantFiled: August 31, 2017Date of Patent: July 5, 2022Assignee: Biomet Manufacturing, LLCInventors: Nicholas Muir, Nathan A.

Patent number: 10070961Abstract: A prosthetic hip stem for use in a prosthetic hip joint. The hip stem generally includes a core having a stem portion and a neck portion, a polymer matrix layer substantially covering the stem portion of the core, and a porous metal layer substantially covering the polymer matrix layer. The polymer matrix layer connects the core and the porous metal layer, and may be injection molded therebetween. The neck portion of the hip stem has a relatively thin or slender profile which allows for an increased degree of articulating movement of the hip stem with respect to the acetabular component of a prosthetic hip joint. The neck portion of the hip stem additionally includes a version indicator element, such as a bump or a protrusion, which may be tactilely felt by a surgeon to aid the surgeon in positioning the hip stem during a minimally invasive total hip arthroplasty procedure, for example, where direct visualization of the hip stem by the surgeon may not be possible.Type: GrantFiled: February 14, 2006Date of Patent: September 11, 2018Assignee: Zimmer, Inc.Inventors: Stephen H. Hoag, Dale A. Degroff, Douglas H. Wentz, Leslie N. Gilbertson, Roy D. Crowninshield

Patent number: 9775724Abstract: A prosthetic inserter includes an inserter head having at least first and second bosses, at least one of the bosses movable from a first position to a second position, that couple the inserter to a femoral provisional component via a pair of corresponding apertures, such as drill holes, within the articulating surfaces of a selected one of a series of femoral provisional components. Each provisional component of the series is capable of having different aperture distances measured between a respective pair of apertures. The bosses of the inserter are biased into an engagement position in which the inserter can be secured to a femoral provisional component to eliminate the need for an external engagement force to be supplied to the inserter.Type: GrantFiled: May 14, 2015Date of Patent: October 3, 2017Assignee: Zimmer, Inc.Inventors: Jeff Blaylock, Jody L.

Publication number: 20150257888Abstract: Prosthetic hip stems for use in prosthetic hip joints and, in particular, provides prosthetic hip stems that are designed to achieve more optimized outcomes with certain types of patient anatomy, such as the anatomy of female patients and/or patients having osteoporosis. Each hip stem in a family or set of hip stems has diaphyseal width, metaphyseal width, offset, and head height dimensions. In a set of hip stems of increasing nominal size, the diaphyseal width dimension increases substantially non-proportionally to the corresponding increase of the metaphyseal width, offset, and head height dimensions, thereby providing a family or set of hip stems that is particularly adapted for patients having osteoporosis, in which the cortical bone of the diaphysis of the femur becomes thinner with progression of the osteoporosis.Type: ApplicationFiled: May 18, 2015Publication date: September 17, 2015Inventors: Dean M.
