Beta-Tricalcium Phosphate Synthetic Bone Graft. Callisto Granules are resorbable calcium phosphate synthetic bone graft for use in filling bony voids or gaps in the skeletal system and may be used in the extremities, posterolateral spine and non unions to promote bone growth.
The granules’ high, interconnected porosity allows them to absorb saline, blood, bone marrow aspirate (BMA) and platelet-rich plasma (PRP) more effectively than leading competitors’ products.
