Osteogenesis only occurs with autograft tissue and allograft cellular bone matrices, such as Trinity ELITE ( MTF / Orthofix, BIO4 / Stryker ) and Osteocel Plus ( AlloSource / NuVasive ).

This procedure was a modification of the medical procedures microfracture and autologous autograft transplantation, two surgeries with shortcomings in terms of difficulty, expense, surgical morbidity and availability of grafting material.
33.
The graft material used can be either an autograft, an allograft, a xenograft, an alloplast ( a growth-factor infused collagen matrix ), synthetic variants, or combinations thereof.

Degrading the glial scar with chondroitinase has been shown to promote recovery from spinal cord injury, especially when combined with other techniques such as nerve guidance conduits, schwann cell transplants, and peripheral nerve autografts.
35.
The semitendinosus tendon can be harvested using a hamstring stripper for use as the reconstruction autograft . The autograft is sectioned into a 16-cm length for the sMCL reconstruction and 12-cm length for the POL reconstruction.

The pulmonary autograft, now widely known as the Ross procedure, first performed in 1967, was the logical development of the homograft : it involves replacing a patient s damaged aortic valve with his or her own pulmonary valve.
38.
Another procedure for aortic valve replacement is the Ross procedure ( after Donald Ross ) or pulmonary autograft . The Ross procedure involves going to surgery to have the aortic valve removed and replacing it with the patient's own pulmonary valve.
39.
The most frequently used is called guided bone graft augmentation where a defect is filled with either natural ( harvested or autograft ) bone or allograft ( donor bone or synthetic bone substitute ), covered with a semi-permeable membrane and allowed to heal.
40.
As an adjuvant to allograft bone or as a replacement for harvested autograft, bone morphogenetic proteins ( BMPs ) appear to improve fusion rates after spinal arthrodesis in both animal models and humans, while reducing the donor-site morbidity previously associated with such procedures.
