## Indications for use
Synthetic Bone Putty is a bone void filler intended for use in bony voids or gaps of the skeletal system that are not intrinsic to the stability of the bony structure. These defects may be surgically created or a result of traumatic injury to the bone. Synthetic Bone Putty is indicated to be packed gently into bony voids or gaps of the pelvis and posterolateral spine and may be used either standalone or in combination with autograft as a bone graft extender. The device is resorbed and replaced with host bone during the healing process.
