The nanocomposite can have non-voids or be nano-void free and can form larger macro-structures and macro-composite structures. The nanocomposite can contain free carbon domains in an amorphous SiOC matrix.

Abstract: An instrument can comprise an instrument body, a cross-pin, and a ring. The instrument body can be configured to be partially inserted into an intramedullary canal of a bone having a bone resection. The cross-pin can extend through the instrument body, and the ring can be movably coupled to the cross-pin and positionable on the bone resection. The ring can be configured to pivot about a longitudinal axis of the cross-pin such that an angle of the ring relative to the instrument body approximates a surface angle of the bone resection relative to the instrument body. Additional apparatus, methods, and systems are disclosed.

Abstract: The present disclosure provides a shoulder prosthesis. The shoulder prosthesis includes a glenoid component, a humeral component, and an articulation component.

Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removeably locks or helps to removeably lock or fix the quasi-spherical member in the bore.

Abstract: There is provided synthetic proppants, and in particular polysilocarb derived ceramic proppants. There is further provided hydraulic fracturing treatments utilizing these proppants, and methods of enhance hydrocarbon recovery.
