ABSTRACT:
A bone alignment assembly is disclosed having bone anchor subassemblies for securing to both bones and a bone position retainer, wherein the bone position retainer includes a longitudinal member for maintaining a desired alignment of the bones when the bone anchor assemblies are secured to the bone position retainer. Each of the bone anchor subassemblies includes a shaft and one or more pairs of components (e.g., washers) wherein the components of each pair have mating spherical concave and convex surfaces that can mate together in a plurality of angular positions. When the shaft extends through each of the pairs of mating components, and also through a passageway of the bone position retainer that is sandwiched between the two pairs of mating components, the shaft can be secured at any one of a plurality of orientations relative to the bone position retainer.
