Abstract: Arthroplasty components include an articular surface and a bone-facing surface. The bone-facing surface includes a concave arrangement of planar surfaces which converge as they approach a middle portion of the articular surface. Instruments and implantation methods are also disclosed.

Abstract: A stemmed implant comprises a proximal body with a distal shaft extending from the proximal body. The proximal body exterior may be spherical, conical, cylindrical, or another surface of revolution. The distal shaft comprises multiple longitudinal ridges which may originate from the proximal body as separate columns, or which may merge together. The distal shaft and/or the ridges may become narrower as they extend away from the proximal body.

Abstract: A system for decision management is described which enables a practitioner to collaborate on treatment options and outcomes. The practitioner may access a remote server through any number of electronic devices, e.g., smart phone, computer, tablet, personal digital assistant, etc. to conduct any number of searches for related treatments of interest, use of products during treatments, one or more particular doctors, condition of a patient at a starting point, resulting outcome from treatments, or any other number of conditions or features.

Abstract: A drill guide includes a working portion and a shaft, with a joint formed between the working portion and the shaft so that the shaft is movable relative to the working portion about the joint. The working portion includes at least one drill guide hole which receives a drill for making a hole in a bone. The joint isolates the working portion from unintentional movements of the shaft so that the working portion remains stable against a bone surface. The joint also enables the shaft to be used as a retractor or pry bar against surrounding anatomical structures if desired. The drill guide may be included in a system with an implant component and/or other surgical instruments.
