  • Publication number: 20210000605
    Abstract: A glenoid implant comprises a body comprising: an articular surface and a scapula-engaging surface, the scapula-engaging surface including first and second portions angled relative to each other; and a fixation feature extending from the scapula-engaging surface. A method comprises: forming a planar bone surface at a glenoid using a guide pin; forming a first bore into the glenoid located near the guide pin; forming a second bore into the glenoid offset from the first bore; inserting an augment ream guide into the first and second bores; and forming an angled bone surface at the glenoid relative to the planar bone surface using the augment ream guide. A ream guide comprises: a base having first and second surfaces; a bone peg extending from the first surface; an alignment peg spaced from the bone peg; and a guide peg extending from the second surface at an oblique angle to the bone peg.

  • Publication number: 20200352726
    Abstract: 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.

  • Patent number: 10828067
    Abstract: A system for compressing a fracture can include a first bone plate having a first proximal end and a first distal end, and a second bone plate having a second proximal end and a second distal end. The second bone plate can be spaced apart from the first bone plate. The system can include an expansion member coupled to the second proximal end of the second bone plate. The movement of the expansion member relative to the second bone plate can cause the first distal end of the first bone plate and the second distal end of the second bone plate to move toward each other to compress the fracture.

  • Publication number: 20190336144
    Abstract: 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.
