Abstract
Stemless components and fracture stems for joint arthroplasty, such as shoulder arthroplasty, are disclosed. Also, methods and devices are disclosed for the optimization of shoulder arthroplasty component design through the use of medical imaging data, such as computed tomography scan data.
Claims22
A prosthesis comprising:
- a central body;
- and
- a plurality of fins extending laterally from an outer surface of the central body,
- the plurality of fins being spaced apart asymmetrically around the outer surface of the central body,
- wherein all of the plurality of fins do not create bilateral symmetry of all of the plurality of fins with respect to a plane containing the longitudinal axis due to the spacing in the reference plane of the plurality of fins,
- wherein at least one of the plurality of fins has an inner perimeter and an outer perimeter, the inner perimeter and the central body defining at least one window, at least one of the fins having the at least one window includes one or more throughholes in a wall defined by the inner perimeter and the outer perimeter of the fin having the at least one window;
- a proximal section having a first articular surface dimensioned to articulate with a second articular surface of a native bone or a prosthetic component;
- and
- a stem connected to the central body, the stem being dimensioned to be received by an opening in the central body.

A prosthesis comprising:
- a central body having a first section and a second section;
- and
- a plurality of fins extending laterally from an outer surface of the central body, the plurality of fins being spaced apart asymmetrically around the outer surface of the central body,
- wherein all of the plurality of fins do not create bilateral symmetry of all of the plurality of fins with respect to a plane containing the longitudinal axis due to the spacing in the reference plane of the plurality of fins,
- wherein the first section has a first longitudinal axis and the second section has second longitudinal axis angled with respect to the first longitudinal axis;
- and
- wherein at least one of the plurality of fins is configured to align a first fin segment with the first longitudinal axis and align a second fin segment with the second longitudinal axis.
