What is it indicated for?
BioSphere Flex is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere Flex is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e., the extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. BioSphere Flex must be hydrated with autogenous bone marrow prior to implantation. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
