摘要: Two component, storage stable apatitic cement compositions, as well as methods for their production, are provided. The dry component of subject apatitic cements comprises basic calcium source particles at least partially coated with a partially neutralized acidic calcium phosphate. The dry component of subject compositions is prepared by combining basic calcium source particles with dissolved acidic phosphate in at least a partially aqueous medium, whereby the basic calcium source particles become partially coated with a partially neutralized acidic calcium phosphate. The reaction is terminated prior to completion of the reaction between the acidic phosphate and the basic calcium source by removing the available water from the reaction mixture. In a first mode, the subject cement may be produced by mechanically mixing an acidic phosphate source with basic calcium source particles in the presence of an aqueous solvent and stopping the reaction between the acid and base prior to completion. Alternatively, a phosphoric acid solution may be rapidly combined with a basic calcium phosphate particle slurry such that partially neutralized acidic calcium phosphate precipitates on the surface of the basic calcium phosphate particles.

摘要: Methods and compositions for use in bone repair are provided. The subject methods employ a two component calcium phosphate cement having a dry component and a lubricant, wherein the dry component of the cement comprises basic calcium phosphate particles at least partially coated with a partially neutralized acidic calcium phosphate. In the subject methods, the dry component and lubricant of the cement are combined to produce a moldable paste which is capable of hardening into a solid mass. The moldable paste may be introduced at a bone repair site and allowed to harden in situ. Alternatively the paste may be allowed to harden and then shaped to obtain a preformed object useful in bone repair.

摘要: The invention relates to a syringe for delivery of a bone substitute material. The syringe includes a barrel for holding the material, a plunger receivable within the barrel and having a threaded portion, and an engagement member including a threaded throughbore positioned coaxial with the barrel. The threaded portion of the plunger is movable through the threaded throughbore barrel by pushing the plunger in the axial direction, and by rotating the plunger. The invention also relates to a method of expelling material from a syringe.
