A bone cement having a dry component including a large constituent and a small constituent. The small constituent fills a substantial volume of the interstitial spaces between the particles of the large constituent. Therefore, only a second or minor interstitial space is left remaining between the individual particles of the small constituent and the particles of the small constituent and the particles of the large constituent. Therefore, a reduced amount of a polymerizable component need be added to the dry component to form a bone cement. Such a bone cement formulation decreases the exothermic temperature of the bone cement and decreases the possibility of tissue necrosis in the implantation area.

The invention relates to an apparatus and method for stabilization of a shunt relative to a bone. The apparatus includes a body member and a plurality of attachment members forming a part of the body member. Each of the attachment members are operable to receive a bone screw so as to secure the body member to the bone. A plurality of movable fingers are movably attached to the body member. The plurality of movable fingers are adapted to engage and stabilize various size shunts relative to the bone.

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.

A material with chemically induced surface charges is employed to foster formation of mammalian hard and soft connective tissues. The material may be in the form of beads such as ion exchange resins. Bead materials with a negative surface charge stimulate formation of hard tissue within long bones and foster bony repair of defects in parietal bones and in mandibular rami. Beads with positively charged surfaces engender formation of large quantities of soft dense connective tissue when implanted into defects in the cranium or when used as an onlay on the nasal bone surface. The use of such beads or other charged biodegradable materials and the use of other surface charged materials with different physical configurations provides significant improvement in hard and soft connective tissue repair, augmentation and replacement in medical fields such as orthopaedic and maxillofacial surgery.
