The authors concluded that the ABM/P-15 composite demonstrated promising results for achieving fusion in patients who undergo ALIF for degenerative spinal diseases.196. Lauweryns et al.191 (level III) reported on a prospective clinical and radiological analysis of patients undergoing a PLIF procedure, comparing ABM/P-15 to local autograft. Putzier M, Strube P, Funk JF, et al. Rick Sasso reports royalties and personal fees from Medtronic, outside the submitted work. At 12-month follow-up there were non-significant differences (p = 0.08) in the rates of fusion, with the 750 group achieving the highest (100%) and the 150 group the lowest (50%). However allograft use alone for instrumented posterolateral lumbar fusions is not well supported, with two level II studies reporting inferior fusion rates, although there were no differences in clinical outcomes. The site is secure. However, bone graft substitutes are widely used and account for more than 2 million surgeries annually worldwide, according to a 2015 review of bone graft substitutes published in World Journal of Orthopedics..

Allografts in combination with bone marrow aspirates have shown good fusion efficacy for posterolateral lumbar fusions in two recently published level II studies. Lastly, data on stem cell based products and the synthetic peptides is currently very limited, having only recently popped up on the horizon. The authors also found no significant differences in clinical results (VAS, ODI, and SF-36) between the groups at each postoperative visit. Significantly higher fusion rates (99 % vs. 76%) were also reported in the study group (p < 0.001), assessed with radiographs and CT. Slosar et al.118 reported a 100% fusion rate at 24 months follow-up after anterior lumbar interbody fusions using rhBMP-2 and femoral ring allograft.

More better quality studies are required comparing these substitutes and extenders not just with autografts, but also with each other. Despite the remarkable advancements in the field of bone graft alternatives for spinal fusion, no graft substitute/expander to date has demonstrated clear superiority over autologous iliac crest graft. All subjects were scheduled for anteroposterior radiographs of the lumbar spine at 3, 6, 12, 18, and 24 months. Since demineralized bone matrices lack structural strength, they cannot be used independently in situations where biomechanical stability is required. Kleeman TJ, Ahn UM, Talbot-Kleeman A. Laparoscopic anterior lumbar interbody fusion with rhBMP-2: a prospective study of clinical and radiographic outcomes. Bone Grafts in Spine Surgery. Yue W-M, Brodner W, Highland TR. For posterolateral lumbar fusion surgery, two Level II studies by An25 and Jorgenson et al.26 demonstrated inferior radiological fusion results for cortico-cancellous allografts (35 - 39.1% fusion rates) compared to autologous iliac crest grafts (up to 80%). Glassman SD, Carreon L, Djurasovic M, et al. The authors concluded that the combination of an osteoinductive agent with an osteoconductive matrix may be an effective replacement for autograft in instrumented single-level PLIF.

Approximately 30% of the U.S. population reports back pain, of which 2% receive a diagnosis, and 65% get treatment. Prospective comparison of autograft vs. allograft for adult posterolateral lumbar spine fusion: differences among freeze-dried, frozen, and mixed grafts. In a prospective case control study involving 58 patients with degenerative spinal stenosis, Hsu et al.83 (level II) compared coralline hydroxyapatite (CHA) and laminectomy-derived bone as adjuvant graft materials for posterolateral lumbar fusions. With many successful bone graft options available today, your surgeon will select the right type(s) for you to give your spinal fusion the best chance of healing properly. After a level I randomized controlled study, Michielsen et al.109 reported results in 40 patients treated with an instrumented single-level posterior lumbar interbody arthrodesis. Bone graft and/or bone graft substitute is needed to create the environment for the solid bridge to form. Nandyala SV, Marquez-Lara A, Singh K.

Int J Spine Surg. Sys J, Weyler J, Van Der Zijden T, Parizel P, Michielsen J. Platelet-rich plasma in mono-segmental posterior lumbar interbody fusion. Three types of bone grafts can be classified ( Table 1 ): (i) autografts: the donor is the same as the receiver; (ii) allografts: the donor is human but is different from the receiver; (iii) xenografts: the donor is from different animal species (heterologous graft). Autograft versus coralline hydroxyapatite. Taking bone from your own body means your surgical time can be longer (if it is not taken from the vertebra) because it adds an additional surgical site to your procedure. A bone graft is defined as using bone-in spine fusion surgery. IL, Bone Morphogenetic Proteins (BMP) are another type of bone graft option, as detailed on the following page. For Group 3, the fusion rate (57.9%) was markedly lower than that in Groups 1 and 2 (90.0 and 78.9%, respectively). OrthoInfo by the American Academy of Orthopaedic Surgeons. government site.

Kong S, Park JH, Roh SW. A prospective comparative study of radiological outcomes after instrumented posterolateral fusion mass using autologous local bone or a mixture of beta-tcp and autologous local bone in the same patient. There are several substances such as ceramics, calcium phosphates and other synthetic materials that have similar biomechanical properties and structure similar to that of cadaver bone and may be used as a bone graft substitute. They are used as bone graft substitutes due to their osteoconductive properties, which provide an inert scaffold for fusion to occur. Additionally, these were sub-categorized according to use in a particular anatomical segment of the spine, where applicable, or for a particular condition, such as spinal deformity. iliac crest, ribs, local bone source) Age, length of fusion, location, and concurrent diseases should be definitive for fusion outcome; papers on spinal arthrodesis should neatly stratify these variables. Common combinations include collagen and ceramic to mimic the structure of a patients own bone, DBM and bone marrow cells to stimulate new bone growth, and BMP and ceramics. Use of allograft bone for posterior C1-2 fusion. 119 patients undergoing surgery were randomized 1:1 for bone-grafting (59: ICBG group and 60: OP-1 group). Outcomes of bone morphogenetic protein-2 in mature adults: posterolateral non-instrument-assisted lumbar decompression and fusion. Dental bone graft substitutes are used mostly in ridge augmentation, implant bone regeneration, sinus lift procedures, periodontal defect regeneration, and socket preservation. Kim HJ, Buchowski JM, Zebala LP, Dickson DD, Koester L, Bridwell KH. Over time, results with rhBMP-2 have been . Bone Graft Site Pain and Morbidity After Spinal Fusion, Back Surgery Video: How Spinal Fusion Stops Back Pain. Instead, the bone graft provides the foundation and environment to allow the body to grow new bone and fuse a section of the spine together (into one long bone). 2008 May-Jun;8(3):457-65. doi: 10.1016/j.spinee.2007.03.012. Comparison of TLIF with rhBMP-2 versus no TLIF and higher posterolateral rhBMP-2 dose at L5-S1 for long fusions to the sacrum with sacropelvic fixation in patients with primary adult deformity. A 92% fusion rate was reported in the allograft group compared to 95% for autograft (p > 0.05). 2019;16(2):94-110. doi: 10.2174/1567201815666181024142354. Bone graft substitutes are widely used in the field of orthopedics and are extensively used to promote vertebral fusion. Bone grafting is a surgical procedure in which damaged bone is replaced with autograft tissue, allograft tissue or a bone graft substitute, which can be either synthetic or metal. 2007 May-Jun;7(3):318-25. doi: 10.1016/j.spinee.2006.02.005. The Spine Journal. HHS Vulnerability Disclosure, Help Bone graft material can be used to fill in gaps at the site of spinal fusion surgery. Harshavardhana et al.104 in a series of 35 AIS patients (level IV), reported no evidence of pseudarthrosis with the use of Si-CaP (Actifuse) at 2.9 years of average follow up. Boden SD, Zdeblick TA, Sandhu HS, Heim SE. The routine supplemental use of anterior cervical plates for instrumentation in recent studies, has resulted in a dramatic increase in fusion rates overall. A prospective non-blinded trial (level II) involving 67 patients who underwent PLIF using two cylindrical threaded fusion cages was conducted by Haid et al.120 Study participants were randomly assigned to one of two groups: investigational (n = 34), who received rhBMP-2 on an absorbable collagen sponge (4-8 mg dose), and the control group (n = 33), who received autologous ICBG. Another example of therapeutic proteins are bone morphogenetic proteins (BMPs) used in spinal fusions. Safety, efficacy, and dosing of recombinant human bone morphogenetic protein-2 for posterior cervical and cervicothoracic instrumented fusion with a minimum 2-year follow-up. "BMP is a potent molecule and its commercial growth has slowed due to its side effects. The material properties of hydroxyapatite are similar to other ceramics; however, compared to the more porous tricalcium phosphate scaffolds, HA products are relatively inert and take longer for biodegradation and resorption.81. Real bone refers to bone graft coming from your own body (known as autograft or autogenous) or harvested from a cadaver donor (called allograft). Wu MH, Lee MH, Wu C, Tsai PI, Hsu WB, Huang SI, Lin TH, Yang KY, Chen CY, Chen SH, Lee CY, Huang TJ, Tsau FH, Li YY. Definitive evidence of osteoinduction in humans: a preliminary report. The use of platelet gel in posterolateral fusion: preliminary results in a series of 14 cases. Schizas C, Triantafyllopoulos D, Kosmopoulos V, Tzinieris N, Stafylas K. Posterolateral lumbar spine fusion using a novel demineralized bone matrix: a controlled case pilot study. It is perfectly normal to feel pain after surgery, and it is a natural part of the healing process. Luhmann SJ, Bridwell KH, Cheng I, Imamura T, Lenke LG, Schootman M. Use of bone morphogenetic protein-2 for adult spinal deformity. Two level III reports explored the use of DBM in scoliosis patients. HHS Vulnerability Disclosure, Help Yan L, Chang Z, He B, et al. The authors found no statistically significant differences in the radiological fusion rates between the two groups (85% with autograft versus 80% with allograft) based on 12 month post-operative radiograph assessment (k = 0.90). Bone graft substitutesthese are synthetic or a manipulated type of naturally-occurring product. Object Autograft and allograft, the standard approaches for lumbar fusion procedures, have important disadvantages. Demirkiran HG, Akel I, Ylmaz G, Ayvaz M, Alanay A, Yazc M. Long-segment posterior instrumentation and fusion with freeze-dried allograft in congenital scoliosis. Careers. Researchers are seeing promise in the bone healing properties of bone marrow-derived mesenchymal stem cells, gene therapy, and tissue engineering. The use of DBM as a bone expander to augment autograft is supported, especially in the lumbar spine.
