Abstract
A bone gel composition consists of cortical bone. The cortical bone is made from cut pieces freeze-dried then ground into particles and demineralized then freeze-dried. A volume of the particles is placed in a solution of sterile water to create a mixture, the water volume being twice the second portion, the mixture is autoclaved under heat and pressure to form a gelatin, the resulting bone gel is placed in jars and kept at room temperature or frozen for later use. The cortical bone has the cut pieces having a width, a length and a thickness in the range of 1 to 4 mm The cortical bone pieces are ground to a particle size up to 125 microns.

A bone gel composition consisting of cortical bone consists of cortical bone made from cut pieces freeze dried then ground into particles and demineralized then freeze-dried, wherein a volume of the particles is placed in a solution of sterile water to create a mixture, the water volume being twice the second portion, the mixture is autoclaved under heat and pressure to form a gelatin, the resulting bone gel is placed in jars for later use.
The bone gel composition of claiml wherein the bone gel when placed in jars is then frozen.
A method of making a bone gel composition consisting of cortical bone comprises the steps of:
- preparing 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 DBM particles;
- autoclaving a volume of the 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 to form a bone gel;
- and
- packaging the resulting bone gel.
