    Abstract: A device including a first plate configured to interface with a first bone structure of a joint; a second plate configured to interface with a second bone structure of the joint opposite the first bone structure; and at least one mechanical actuation mechanism disposed between the first plate and the second plate and configured to apply a distraction force along an axis between the first plate and the second plate so as to urge the first plate and the second plate away from one another, wherein the device is configured so as to have a range of motion ranging from a minimum distance between the first plate and the second plate to a maximum distance between the first plate and the second plate, and wherein the mechanical actuation mechanism is configured such that the distraction force is substantially constant distraction force across the range of motion.

    Abstract: A proximal portion of an implant for repairing a multipart fracture of a proximal humerus includes an asymmetric body having a proximal end, a distal end, a medial side, a lateral side, an anterior edge, and a posterior edge a medial surface extending along at least a portion of the medial side and having a proximal end and a distal end; a protrusion forming the lateral side of the asymmetric body, offset in an anterior direction, and pointing toward a bicipital groove of the humerus when the proximal portion is implanted in the humerus, an anterior support surface configured to support a lesser tuberosity; a posterior support surface configured to support a greater tuberosity; an angled surface having a first side defined by the medial surface, a second side defined by the anterior support surface, and a third side defined by the posterior support surface; and an anchoring point.

    Abstract: An apparatus includes a processor and a non-transitory memory. The processor is configured to receive pre-operative patient specific data. The pre-operative patient specific data is inputted to a first machine learning model to determine a first predicted post-operative joint performance data output including first predicted post-operative outcome metrics. A reconstruction plan of the joint of the patient is generated based on a medical image of the joint, and at least one arthroplasty surgical parameter obtained from the user. The at least one arthroplasty surgical parameter is inputted into a second machine learning model to determine a second predicted post-operative joint performance data output including second predicted post-operative outcome metrics. The second predicted post-operative joint performance data output is updated to include an arthroplasty surgery recommendation, in response to the user varying the at least one arthroplasty surgical parameter, before the arthroplasty surgery, during the arthroplasty surgery, or both.

    IPC: A61F2/46 ,  A61F2/38

    Abstract: A computer-implemented method including positioning at least one sensor within a joint of a patient; receiving, by a processor, a first data set representing a first series of reaction forces within the joint while the joint is moved through a range of motion; receiving, by the processor, a second data set representing a second series of reaction forces within the joint while the joint is moved through the range of motion while a first trial implant is attached within the joint; calculating, by the processor, a difference between the second data set and the first data set; and providing, by the processor, an instruction based on the difference, the instruction including either an instruction to select a second trial implant if the difference exceeds a threshold, or an instruction to proceed with an actual implant matching the first trial implant if the difference does not exceed the threshold.
