PHILOSOPHY

Currently the “gold standard” for bone grafting is an autograft. If an autograft isn't a good option for the patient, the next best option is normally an allograft. Allograft bone is harvested from cadaveric tissue donors and has been used for many years due to its osteoconductive and osteoinductive properties. However, allograft incorporation into the host bone is slower and less complete compared to autograft. There is also a risk of disease transmission and immune rejection. The main underlying reason for slower and less complete allograft incorporation into native bone is particularly related to lack of vascularisation. The affinity and bone conduction ability of allogeneic bone cells are weak, and osteoblasts have difficulty adhering to and differentiating on their surfaces.

Unfortunately, most synthetic bone graft substitutes lack appropriate osteoinduction, osteoconduction, and osteogenicity. Some show potential, like rhBMP-2 Bone Morphogenetic Protein-2 but were also associated with potential serious complications including ectopic bone formation and possible cancer risks. The fusion rates with alternative bone graft substitutes like BMP-2 is still unclear and fusion rates range widely between studies. Several studies investigated the complication spectrum of BMP-2, including carcinogenicity, and reported a wide range of potential complications, complication rates, and controversial conclusions.

CAGES

To avoid associated problems of graft harvesting, intervertebral cages are an alternative, but cannot provide biological fusion. The major issue with Ti alloys is its low bone-bonding ability; thus, increased research has been done on surface chemical and physical and morphology modifications to improve bone bonding. PEEK polyether ether ketone (PEEK) fusion cage provides stability similar to that of Ti alloys, and in some cases improves durability, strength and overall biomechanical profile. PEEK has radiographic properties that allow surgeons to better monitor possible migration and the success of the implant. However, the primary issue with PEEK is that it is hydrophobic and unable to sufficiently bond to bone to achieve solid fusion, the PEEK cage has few hydrophilic groups, high biological inertia and a smooth surface, and can easily be wrapped by fibrous tissue which cannot provide conditions for the adhesion of osteoblasts, resulting in weak osseointegration ability. This may be associated with cage migration and pseudarthrosis (non-union).

Traditionally, the trephination technique is a well-known bone marrow biopsy method that has been used for diagnostic purposes. Later, the same technique was modified and described as a bone graft harvesting method by enlarging the trephine diameter, and has been used for many years. The trephination technique is a “Closed Method” and has become popular because it can be performed in a smaller incision, and fewer complications have been reported compared to the conventional curettage technique. However, the adequate volume of obtained graft is important for most orthopedic procedures, especially if the size of the bone defect is large. The autograft tricortical iliac crest graft has a wide range of indications.

Autograft tricortical iliac crest graft was most often chosen as the gold standard for choice of graft material for ACDF by surgeons. ACDF surgery with stand-alone tricortical iliac crest autograft also has good fusion rates and satisfactory neurological recovery. Although fusion rates may be higher with instrumented fusion, with plating within 1 year of surgery, standalone grafts can produce good results while reducing the cost of implants. Thus, this is still a viable option for surgeons to consider.

Trephinated curettage technique use of the cylinder osteotome for cancellous and tri-cortical bone grafting. This instrument is designed for removing iliac crest cancellous and cortico-cancellous tri-cortical bone grafts. This device has widespread applications for orthopedic surgery. The convenience of obtaining iliac crest bone grafts with this device broadens the use of bone-grafting techniques in patients in whom the need for ICBG bone graft is indicated.

Autograft, also known as autologous bone graft is the “gold standard” to which all other substitutes are measured. The iliac crest is the most common ‘donor site’ for autograft harvesting. The Autograft Iliac Crest Bone Graft (ICBG) remains the gold standard of all bone grafts. It confers the lowest risk of immunological rejection and has strong osteoconductive, osteoinductive, and osteogenic properties, making it a valuable adjunct to the treatment of conditions such as fracture, delayed union, nonunion, and malunion, bone loss due to trauma, inflammation, and old age; for the reconstruction of bone structures after tumour excision; and for the filling of cyst defects.

Autograft options come in the form of cancellous and cortical bone graft options. Autogenous bone is the only graft material that fulfils all three components of the tissue regeneration triad: osteogenesis, osteoinduction, and osteoconduction. It is also biocompatible, which means that bone harvested from the patient’s own body has no risk of rejection or disease transfer. Autologous bone naturally contains viable cells such as osteoprogenitor cells, as well as essential molecular components like bone morphogenetic proteins (BMPs). Furthermore, autologous bone can provide a calcium scaffold required to support the new bone growth. Its large surface area has the optimal chemistry, structure, and porosity to serve as an excellent scaffold for new bone formation and it contains all the necessary bone-forming growth factors and is inherently osteoinductive. Active and dormant osteoblasts give it osteogenicity. Furthermore, cancellous bone is easily re-vascularized and rapidly incorporated at the host site. Autologous bone can be harvested as a tricortical graft for structural support.

The massive amounts of cancellous bone that can be obtained from the pelvis provide all the desired properties of osteoconduction, osteoinduction, and osteogenicity. Its large surface area has the optimal chemistry, structure, and porosity to serve as an excellent scaffold for new bone formation. Similarly, it contains all the necessary bone-forming growth factors and is inherently osteoinductive. Active and dormant osteoblasts give it osteogenicity. Furthermore, cancellous bone is easily re-vascularized and rapidly incorporated at the host site. There are no concerns for disease transmission and no risks of immunogenicity.
