What is it indicated for?

XeroSyn bone void filler is an implant intended to fill bony voids or gaps of the skeletal system (i.e., extremities and pelvis). XeroSyn is used with autograft as a bone graft extender in the extremities and pelvis. 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. XeroSyn 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.
