Abstract
Disclosed are: a composition for hard tissue repair with excellent penetrability to an adherend such as a cancellous bone and excellent adhesion to an adherend, which comprises a monomer (A), a polymer (B), a polymerization initiator (C) and a contrast medium (X) having a volume mean particle diameter of 3 μm or more; and a kit for hard tissue repair having members in which the components of the monomer (A), the polymer (B), the polymerization initiator (C) and the contrast medium (X) contained in this composition for hard tissue repair are encased in three or more divided groups in an optional combination.
Claims6
A composition for hard tissue repair comprising a monomer (A), a polymer (B), a polymerization initiator (C) and a contrast medium (X) having a volume mean particle diameter of 3 μm or more,
- wherein the monomer (A) is a methyl methacrylate,
- wherein the polymer (B) comprises:
- a polymer powder (b1) having a specific surface area of 0.05 to 0.5 m2/g, and,
- a polymer powder (b2) having a specific surface area of 0.51 to 1.2 m2/g and/or a polymer powder (b3) of particles having a specific surface area of 1.5 to 4.5 m2/g,
- wherein the initiator (C) is a partially oxidized trialkylboron which contains ethanol but does not contain an aprotic solvent, and
- wherein a volume mean particle diameter of all particles contained in the composition for hard tissue repair is 15 to 26 μm.
