What is an allograft for spine surgery?
Cadaver or Allograft Bone Allografts have been used for a long time in spinal fusion surgery. Unlike autografts taken from a patient, allografts do not form new bone. Instead, the allograft works as a bridge that allows the natural bone to grow through its surface. Over time, the natural bone replaces the donor bone.
What is a cortical allograft?
Allograft cortical struts provide an osteoconductive matrix for bone ingrowth and are designed to reinforce cortical defects and provide immediate structural support. Cortical struts are composed of 100% allograft, allowing them to remodel with the patient’s own tissue.
How long does it take a spinal bone graft to heal?
Spinal fusion surgery recovery typically takes anywhere from three to six months, and this time frame includes the various types of physical therapy that each patient must undergo.
Where do bone allografts come from?
A bone allograft is produced from processing of untreated human tissue unlike synthetic medicinal products. If it is demineralised in order to promote its osteoinductive properties, the release of growth factors from the bone will vary from donor to donor.
Can a bone allograft be used in spinal surgery?
Various allograft bone types are available. Successful use of allograft bone in spinal surgery is largely dependent on its placement.
Which is a morselized allograft or structural bone graft?
For a morselized allograft, select 20930. A structural bone graft is a single piece of bone, which provides direct support for skeletal structures. For a structural autograft, select 20938.
How are demineralized bone grafts used in spine surgery?
Demineralized Bone Matrix (DBM) DBM is bone processed in such a way that the calcium in the bone is removed. The benefit of this process is that it makes the proteins trapped in the calcium available to stimulate bone healing. DBMs are usually combined with other types of grafts. Synthetic Bone
What’s the difference between cortical and cancellous allografts?
Cortical allografts are incorporated by creeping substitution with intramembranous ossification, while cancellous allografts are incorporated by enchondral ossification. 1 Demineralized bone matrix (DBM) is allograft that has been decalcified, leaving organic matrix behind.

How is Medtronic allograft tissue used in surgery?
Medtronic Allograft Tissue is used in surgical applications from head to toe, with features, benefits, shapes, sizes, and delivery methods designed to support fusion success. Visit the Allograft Resource Center for resources you may need to download. The following are contraindications for the use of GRAFTON™ DBM and GRAFTON PLUS™ DBM:
