Malleable demineralized bone composition and method of manufacture

A method of making a malleable demineralized bone composition consisting of cortical bone comprises the steps of:

• preparing a first portion of cortical bone by cutting the cortical bone into pieces, freeze-drying the pieces and then grinding into particles and demineralizing the ground particles and the freeze-drying the demineralized ground particles to form a first portion of DBM particles;
• preparing a second portion of cortical bone by shaving wherein cortical bone plates are cut into long pieces, cleaned and then shaved to form shavings of cortical bone tissue then freeze-drying the shavings, grinding the freeze-dried shavings to obtain a particle size less than 150 μm and demineralizing the particles thereafter freeze-drying to form a second portion of DBM particles;
• autoclaving a volume of the second portion of DBM particles mixed with sterile water in a 2:1 ratio by volume for a predetermined time at a pre-set temperature and pressure to form a gelatin;
• cooling the gelatin made from the second portion;
• and
• mixing the freeze-dried ground particles of the first portion with the gelatin from the second portion at a ratio of 80:20 or less gelatin to DBM to create a malleable putty or paste.
