## Indications for use
MasterGraftTMMatrix combined with autogenous bone marrow is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. MasterGraftTM Matrix is to be gently packed into bony voids or gaps of the skeletal system (e.g., the spine, pelvis, ilium, and/or extremities). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. MasterGraftTM Matrix provides a bone void filler that resorbs and is replaced with bone during the healing process.
