The scientific basis of bone transplantation was established during the mid-nineteenth century, when the osteogenic properties of the bone and periosteum, beneficial influence of cold preservation of bones, and first conventional attempt to store bones for elective use, were described. A bone bank has several advantages, such as the immediate availability of grafts in large quantities, and different shapes and sizes, and maintenance of osteoinductive activity in grafts. In addition, it reduces patient blood loss, surgical time, and quantity of anesthetics required. Clinical applications include the correction of comminuted fractures, treatment of non-union bones, and replacement of bone loss due to infections or malignancies. The success of these procedures depends on the preservation and integrity of the graft. This study aimed to evaluate the feasibility of maintaining a canine bone bank (Canis familiaris) by quantifying the bacterial contamination of bone grafts preserved at –24°C. The samples were evaluated through a monthly assessment of bacteriological cultures over a period of 6 months. The harvest method was efficient and sterile, reducing the risk of contamination. We conclude that the techniques chosen for the implementation of a bone bank were effective and feasible (use of a common freezer reaching a temperature below –24°C). The viability of the bones was attested during a 6-month period, and the samples demonstrated a 100% sterility rate.
