Abstract: Devices, systems, and techniques are described for determining surgical guidance for a joint replacement implantation based on dynamic joint analysis. Techniques include receiving patient specific data indicative of pre-operative motion associated with an ankle (300) of a patient and determining, based on the patient specific data, a current kinematic axis (302) of the motion associated with the ankle. Techniques also include determining a target kinematic axis (304) of motion for the ankle, the target kinematic axis being different than the current kinematic axis, and generating a transform function between the current kinematic axis and the target kinematic axis. Additionally, techniques include generating, based on the transform function, a recommended surgical intervention that adjusts tissue associated with the ankle to achieve the target kinematic axis of motion.

Abstract: The disclosed subject matter relates to a system and method for preparing a surface of a bone proximate a joint, in which the preparation includes boring a plurality of arced channels/troughs in the bone surface using an arch drill assembly guided by plural guide bores along a predetermined longitudinal arc. The bored troughs create a scalloped surface on the bone to which an inverse contoured joint insert/implant having cooperating convex ridges engages. The plural guide bores are also defined by the predetermined longitudinal arc which may be circular or helical. The disclosed subject matter minimizes bone removal and allows greater access options for preparing the bone surface.

Abstract: In one aspect, an implant configured to attach a first bone section to a second bone section comprises an intramedullary portion and an extramedullary portion. The intramedullary portion is configured for insertion into the first bone section. The ex-tramedullary portion is configured to abut a surface of the second bone section and includes a first fastener aperture configured to eceive a bone fastener inserted in the second bone section. The intramedullary portion and the extramedullary portion are coupled such that the extramedullary portion is rotatable with respect to the intramedullary portion.

Use of the tip geometries described may allow the cutting element to be positioned at varying angles relative to the surface to be cut. In some instances, a tip geometry for a cutting element may be selected such that it reduces and/or inhibits movement of the cutting element during use and/or allows for a predetermined angle of entry into a surface to be cut.
