ABSTRACT:
A biocompatible osteosynthesis plate operable for being enhanced in a substantially secured relation to a plurality of adjacent bone portions is provided. The biocompatible osteosynthesis plate includes an elongated section having a top face and a bottom face, at least one fastener opening disposed between the top face and the bottom face, and means disposed upon elongated section to permit the formation of additional fastener openings therethrough during a surgical procedure. The osteosynthesis plate is in a first configuration at a first thermochemical state and is operable to be converted to a second thermochemical state so that it may be deformed prior to fixation. The osteosynthesis plate may further include means disposed upon the elongated section for enhancing structural rigidity, which may be provided as one or more raised surfaces, or rails, disposed upon the top face of the osteosynthesis plate.
