Abstract: An intervertebral implant may include an input for expanding at least two extendable support elements connected to a body at respective locations, such that the extendable support elements each apply a respective expansion force directed away from a surface of the body. Application of a single input force to the input may induce the extendable support elements to apply different amounts of expansion force. Alternatively or additionally, an intervertebral implant may include at least two portions connected together by a hinge for articulation about the hinge. In one aspect, the hinge may include at least two rigid links each pivotably connected to the two portions. In another aspect, a rigid link of the hinge may include a passageway for communicating a hydraulic fluid between the two portions. A locking system may be positionable into successive locked configurations by operation of a cam to prevent contraction of an extendable support element.

Abstract: A modular patella trial system and method is provided. A modular patella trial includes an articular element and at least one sizing element. The articular element has a length, a width, and a thickness. The articular element has a posterior and anterior surfaces separated by their thickness. The anterior surface has protrusions extending outwardly. Any of the sizing elements have a length, width, and thickness. Any such sizing elements have posterior and anterior surfaces separated by their thickness. At least one aperture extends through the posterior and anterior surfaces of the sizing elements. Such apertures are capable of receiving a corresponding protrusion of the articular element. The modular patella trial has a thickness substantially equal to the total of the thicknesses of the articular element and the sizing elements used in conjunction with the articular element.

Abstract: A femoral assembly includes a femoral component that includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral component for articulating with a tibial prosthesis and an inner bone facing side opposite the outer side. The inner bone facing side defines five intersecting component inner surfaces that each extend from a lateral side of the femoral component to a medial side thereof. A femoral augment includes condylar portions and an anterior flange portion. The condylar portions and anterior flange portion together define an outer side of the femoral augment comprised of five intersecting augment outer surfaces and an inner side comprising no more than three intersecting augment inner surfaces. The augment outer surfaces correspond to the component inner surfaces of the femoral component. The augment inner surfaces correspond to resected surfaces of a distal femur.

Abstract: A High Energy Beam Processing (HEBP) system provides feedback signal monitoring and feedback control for the improvement of process repeatability and three-dimensional (3D) printed part quality. Electrons deflected from a substrate in the processing area impinge on a surface of a sensor. The electrons result from the deflection of an electron beam from the substrate. Either one or both of an initial profile of an electron beam and an initial location of the electron beam relative to the substrate are determined based on a feedback electron signal corresponding to the impingement of the electrons on the surface of the sensor. With an appropriate profile and location of the electron beam, the build structure is fabricated on the substrate.

Abstract: A method of repairing a fractured humerus may include implanting a prosthetic humeral stem into a humeral canal of the fractured humerus. First and second tuberosities of the fractured humerus may be robotically machined to include first and second implant-facing surfaces that are substantially negatives of first and second surface portions of the proximal end of the prosthetic humeral stem. The first and second tuberosities may be machined so that the first and second tuberosities have first and second interlocking surfaces shaped to interlock with each other. During implantation, the first and second implant-facing surfaces are in contact with the first and second surface portions of the proximal end of the prosthetic humeral stem, and the first interlocking surface interlocks with the second interlocking surface.
