## Indications for use
MagnetOs Granules is an implant intended to fill bony voids or gaps of the skeletal system, i.e., the extremities, pelvis, intervertebral disc space, and posterolateral spine. These osseous defects may be surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. When used in posterolateral spine, extremities and pelvis, MagnetOs Granules may be used standalone or mixed with autograft, blood, and/or bone marrow. When used in intervertebral body fusion procedures, MagnetOs Granules must be used with an intervertebral body fusion device cleared by FDA for use with a bone void filler and hydrated with blood. MagnetOs Granules may also be mixed with autograft. MagnetOs Granules resorbs and is replaced with bone during the healing process.
