Abstract: Variable angle holes in bone plates structured to facilitate the formation of axial compression or tension of a bone, or which can assist in bone distraction. The variable angle hole can extend about a central axis and includes an inwardly extending wedge wall. The variable angle hole can be sized to receive insertion of a fixation element at a location at which a central longitudinal axis of the fixation element is axially offset from the central axis of the variable angle hole by an offset distance at least when the fixation element is initially driven into bone at least in a transverse direction. The wedge wall can be configured to be engaged by a portion of the fixation element in a manner that axially displaces at least one of the bone plate, the fixation element, and/or bone(s) in a direction that can generally reduce or increase the offset distance.

Abstract: A computer implemented method, apparatus and software for storing electronic document interchange (EDI) documents in a hierarchical manner in a memory, whereby the storing of data is performed independent of the type of format of the EDI document. Data is stored based on whether the data is segment data, transaction set data, functional group data, or attribute data, with linkages between these types of data as stored in the memory. That way, data can be retrieved from the memory according to a type of data that is desired to be retrieved.
