Publication number: 20220104837Abstract: An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.Type: ApplicationFiled: December 17, 2021Publication date: April 7, 2022Inventors: Thomas M.

Patent number: 11213400Abstract: An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.Type: GrantFiled: March 20, 2020Date of Patent: January 4, 2022Assignee: ENCORE MEDICAL, L.P.Inventors: Nicholas J.
