Abstract
A bearing plate for use in bone fixation for fractures, fusion osteotomies and the like, and the plate is provided with one or more spherical holes in which expandable spherical bearings can be rotatably supported. Each of the holes is formed at its periphery in such a way as to provide yielding expansibility of the hole so that upon expansion of the bearing, the hole expands with it to provide elastic resistance to the expanding bearing.
