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

Porous Biologic Scaffold is a resorbable bone void filler that is available in two versions:

Version 1 is comprised of a porous collagen mesh that is either prefilled or separately packaged with human demineralized allograft bone matrix. In the prefilled format, the demineralized bone matrix is completely enclosed inside the collagen mesh. In the separately packaged format, an open-ended collagen mesh bag is supplied with separately packaged demineralized bone matrix and is filled and sewn closed with absorbable suture by the clinician. Version 1 of the Porous Biologic Scaffold may be hydrated with blood, saline, or bone marrow aspirate, and are combined with autograft bone prior to implantation.

Version 2 is comprised of a porous resorbable collagen mesh bag either prefilled or separately packaged with activated biphasic ceramic granules. In the prefilled format, the biphasic granules are completely enclosed inside the collagen mesh. In the separately packaged format, an open-ended collagen mesh bag is supplied with separately packaged biphasic granules and is filled and sewn closed with absorbable suture by the clinician. Version 2 of the Porous Biologic Scaffold may be hydrated with blood, saline, or bone marrow aspirate, and are combined with autograft bone prior to implantation.

Both formats of the Porous Biologic Scaffold are supplied terminally sterile and are available in sizes of 18 x 50 mm, 18 x 100 mm, 24 x 50 mm, and 24 x 100 mm.
