## Indications for use
SIGNAFUSE Bioactive Strip (SBS) SIGNAFUSE Bioactive Strip (SBS) is a bone graft substitute intended for use in bony voids or gaps of the skeletal system not intrinsic to the stability of the bony structure. These osseous defects may be surgically created or result from traumatic injury to the bone. SIGNAFUSE Bioactive Strip (SBS) is indicated to be combined with autologous bone marrow aspirate and packed into osseous defects of the extremities, pelvis, posterolateral spine, and intervertebral disc space. When used in the posterolateral spine, SIGNAFUSE Bioactive Strip (SBS) is to be used as an autograft extender. When used in intervertebral disc space, SIGNAFUSE Bioactive Strip (SBS) is to be used as an autograft extender with an intervertebral body fusion device cleared by FDA for use with a bone void filler. The device resorbs and is replaced by host bone during the healing process. SIGNAFUSE Putty SIGNAFUSE Putty is a bone void filler device intended for use in bony voids or gaps that are not intrinsic to the stability of the bony structure. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. SIGNAFUSE Putty is indicated to be packed gently into bony voids or gaps of the skeletal system (i.e., extremities, pelvis, posterolateral spine, and intervertebral disc space fusion procedures). SIGNAFUSE Putty can also be used with autograft as a bone graft extender in the posterolateral spine. When used in intervertebral body fusion procedures, SIGNAFUSE Putty can used on its own or as a bone graft extender, and with an intervertebral body fusion device cleared by FDA for use with a bone void filler. The device provides a bone void filler that is resorbed and replaced with host bone during the healing process.
