Abstract
An osteoimplant is provided which comprises a coherent aggregate of elongate bone particles, the osteoimplant possessing predetermined dimensions and shape. The osteoimplant is highly absorbent and sponge-like in nature. Also provided herein are a method of fabricating the osteoimplant and a method of repairing and/or treating bone defects utilizing the osteoimplant.
Claims20
A method of making an osteoimplant which comprises:
- a. providing a quantity of elongate bone particles;
- b. mixing the elongate bone particles with an aqueous wetting agent to provide a fluid composition containing from about 5 to about 40 volume percent swollen, hydrated elongate bone particles;
- c. introducing the fluid composition into a mold;
- and,
- d. removing aqueous wetting agent thereby providing a coherent aggregate of elongate bone particles possessing dimensions and a shape of the osteoimplant.
A method of making an osteoimplant, the method comprising:
- a. mixing bone particles with an aqueous wetting agent to provide a fluid composition containing from about 5 to about 40 volume percent swollen, hydrated bone particles;
- b. introducing the fluid composition into a mold;
- and,
- c. removing aqueous wetting agent thereby providing a coherent aggregate of bone particles possessing a shape of the osteoimplant.
A method of making an osteoimplant, the method comprising:
- a. mixing bone particles with an aqueous wetting agent to provide a fluid composition containing from about 5 to about 40 volume percent swollen, hydrated bone particles;
- b. introducing the fluid composition into a mold;
- and,
- c. removing aqueous wetting agent to cause mechanical entanglement of the bone particles thereby providing a coherent aggregate of bone particles possessing a shape of the osteoimplant.
