Abstract
A moldable bone composition consists of a mixture of: cortical bone and cancellous bone. The cortical bone is formed in three portions, a mineralized shaving portion and a demineralized shaving portion and a mineralized powder portion. The cancellous bone is formed in a mineralized crushed cancellous portion. The portions are free-dried and mixed together to form a freeze-dried moldable bone composition.

A moldable bone composition consisting of a mixture of:
- cortical bone and cancellous bone, the cortical bone is formed in three portions, a mineralized shaving portion and a demineralized shaving portion and a mineralized powder portion;
- the cancellous bone is formed in a mineralized crushed cancellous portion, the portions are freeze-dried and mixed together to form a freeze-dried bone composition;
- and
- wherein when subjected to a fluid, the composition can be molded to a desired shape.

A method of manufacturing a moldable bone composition comprises the steps of:
- cutting cortical bone plates into long pieces;
- shaving the cortical bone plates to form cortical strands or shavings 3 mm or greater in length;
- demineralizing a first portion of the cortical shavings;
- grinding another portion of the cortical shavings;
- resulting in cortical bone having three portions, a demineralized cortical shavings portion, a mineralized cortical shavings portion and a powered cortical portion;
- cutting and grinding cancellous bone to form a portion of mineralized crushed cancellous bone from a size of 1000 to 1700 microns;
- freeze-drying each portion;
- and
- mixing together all of the portions in a predetermined ratio to form a freeze-dried composition.
