Assessment of fusion was done with AP and lateral radiographs at various time points. Bone graft substitutes for spinal fusion. There were no significant differences in recovery rates using the SF-36 and Japanese Orthopedic Association ( JOA) scores at all time intervals. Clinical and radiographic outcomes of posterolateral lumbar spine fusion in humans using recombinant human bone morphogenetic protein-2: an average five-year follow-up study. Vaccaro et al.165, 166 reported long term (4 year) outcomes with the use of OP-1 for non-instrumented posterolateral fusions in two independent level I studies, and OP-1 was found equivalent to autograft in terms of safety and efficacy in both. Epub 2007 Apr 6. Bone Grafts in Spine Surgery. However their complication profile, which was beyond the scope of discussion of this review, as well recent studies re-evaluating the risks/benefits with BMP use, require physicians to reconsider their routine application in spinal fusion procedures. Definitive evidence of osteoinduction in humans: a preliminary report. In another level I prospective randomized study, Kanayama167 concluded that OP-1 reliably induced new bone formation, even without autogenous bone graft, but that the fusion rate was not encouraging. Preliminary study showing safety/efficacy of nanoss bioactive versus vitoss as bone graft expanders for lumbar noninstrumented fusions. Higher physical function scores were observed in the DBM group at 2 year follow-up, although this also was not statistically significant. In a prospective randomized trial (level I) involving 40 patients, Sys et al.173 studied the application of platelet-rich plasma (PRP) for single level posterior lumbar interbody fusion procedures. 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. Hsu C-J, Chou W-Y, Teng H-P, Chang W-N, Chou Y-J. Repair fractures of the spine. Nineteen patients had supplemental bone grafting with DBM putty enriched with aspirated bone marrow, 27 patients had DBM putty combined with iliac crest autograft, and the control group consisted of 27 patients with autograft. A comparison of autogeneic and allogeneic bone grafts. Patients were observed clinically and radiologically for a minimum of 20 months postoperatively, with a mean follow-up of four years. Twelve-month results of a multicenter, blinded, pilot study of a novel peptide (B2A) in promoting lumbar spine fusion. Significant improvements in clinical outcome measures were also reported in both groups. To stimulate the bone fusion, a spine surgeon will use additional bone called bone graft. Yan L, Chang Z, He B, et al. Background: Although autogenous iliac bone graft (AIBG) remains the gold standard for spine fusion, harvesting morbidity has prompted the search for alternatives especially for multi-segment fusion. Hurlbert RJ, Alexander D, Bailey S, et al. Cortical allografts in spinal tuberculosis.

CT scans of the arthrodesed segments were made at three, six, and twelve months postoperatively, as well as bone density measurements. Lauweryns P, Raskin Y. There are several main types of bone graft substitutes used in spinal fusion surgery, which can be generally categorized into three main areas: Demineralized Bone Matrix (DBM) Synthetic bone graft extenders Bone Morphogenetic Proteins (BMP). The use of rhBMP-2 in the treatment of pyogenic vertebral osteomyelitis is a relatively novel application. Before Delecrin et al.78 also reported favorable results for the use of porous biphasic calcium phosphate ceramic blocks comprised of -TCP and hydroxyapatite (Triosite) in 58 patients with idiopathic scoliosis. Level III177 and level IV data178180 are contradictory, with two studies178, 180 supporting use in lumbar fusions and two others177, 179 questioning efficacy in view of the inferior fusion rates obtained. Katayama Y, Matsuyama Y, Yoshihara H, et al. Though efforts to identify the ideal carrier are ongoing, absorbable collagen sponges (ACS) and compression resistant matrix (CRM) are frequently used. Bhatnagar RS, Qian JJ, Wedrychowska A, Smith N. Construction of Biomimetic Environments with A Synthetic Peptide Analogue of Collagen. 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). All groups related reliable fusion rates with rhBMP-2, ranging 93.5% to 100%, suggesting equivalence to autologous iliac crest bone. 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. The advantages include no risk of disease transmission and ready availability. Ajiboye RM, Hamamoto JT, Eckardt MA, Wang JC. Epub 2018 May 16. FOIA Bone graft substitutes are widely used in the field of orthopedics and are extensively used to promote vertebral fusion. Thaler M, Lechner R, Gstttner M, Kobel C, Bach C. The use of beta-tricalcium phosphate and bone marrow aspirate as a bone graft substitute in posterior lumbar interbody fusion. Autologous and allogenic bone grafts, ceramics, DBMs and polylactic acids are other substrates that have been utilized for rhBMP delivery. Malham GM, Giles GG, Milne RL, Blecher CM, Brazenor GA. It is only recommended as a bone graft extender and not as a replacement. All studies using BMP showed 100% fusion rate despite length of the study or whether additional bone graft substitutes were used. Technical report. Bone Grafts And Substitutes Market Size, Share & Trends Analysis Report by Material Type (Allograft, Synthetic), by Application (Spinal Fusion, Foot & Ankle, Joint Reconstruction), by Region, and Segment Forecasts, 2022-2030 Hamer AJ, Strachan JR, Black MM, Ibbotson CJ, Stockley I, Elson RA. In another level II study, Singh et al.119 reported an overall 97% fusion rate in the rhBMP-2 group (12 mg dose) compared to a 77% fusion rate with ICBG alone (p < 0.05) for instrumented posterolateral fusions. The use of freeze-dried fibular allograft in anterior cervical fusion. Careers. Unfortunately, since that is not the rule, conclusions drawn from current literature are very unreliable. The procedure of anterior lumbar interbody fusion (ALIF) is commonly performed on patients suffering from pain and/or neurological symptoms associated with disorders of the lumbar spine caused by disc degeneration and trauma. These grafts show promise operating as a scaffold (providing a framework for bone growth), but they cant stimulate bone growth on their own. Accessed November 2, 2018. Bone Graft Substitutes The formation of new bone requires three key processes: osteogenesis (synthesis of new bone), osteoinduction (recruitment of stem cells and their differentiation into bone cells), and osteoconduction (the development of adequate blood supply to the new bone and correct structuring of the new bone cells). The body part is joined together by fixation device, bone graft, or other means. However, no comparison with autograft was done by the authors in the study. Disclaimer, National Library of Medicine The basic idea of spinal bone graft fusion is to fuse two painful bones in the spine. Your doctor will consider your age, specific spine condition, and overall health when deciding what type(s) of bone graft to use. The reported fusion rates were 87.0% in the -CPP group and 89.1% in the autograft group, which were not significantly different. Landi A, Tarantino R, Marotta N, et al. Clinical outcomes using the Oswestry low back pain Disability Index (ODI) also demonstrated no significant differences in allograft and autograft groups. Bone marrow concentrate with allograft equivalent to autograft in lumbar fusions. More better quality studies are required comparing these substitutes and extenders not just with autografts, but also with each other. Lee JH, Lee DH, Ryu HS, Chang B-S, Hong KS, Lee CK. Unable to load your collection due to an error, Unable to load your delegates due to an error. The https:// ensures that you are connecting to the For bones to fuse or heal together, additional bone is needed. Common sources include the pelvis, legs, and other parts of the spinal column. Beta-Tricalcium Phosphate (-TCP), Hydroxyapatite (HA), Calcium Sulphate and more recently Silicate-Substituted Calcium phosphate (Si-CaP) and Calcium pyrophosphate (-CPP) are among the most notable ceramic scaffolds that have been studied for use in human spinal fusions. However four level IV studies (using CHA88, porous HA89, porous/dense HA composite90 and nano-HA/polyamide cages91) reported good results (fusion rates ranging from 92.50% to 100%) and concluded that HA was an effective alternative to autologous iliac crest graft. Lerner T, Liljenqvist U. Silicate-substituted calcium phosphate as a bone graft substitute in surgery for adolescent idiopathic scoliosis. A review of clinical articles on the topic of bone graft substitutes/expanders/extenders was conducted. He then completed a residency in Chiropractic Orthopaedics from the same school and was in private practice for five years. 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. McAnany SJ, Ahn J, Elboghdady IM, et al. Ont Health Technol Assess Ser. Epstein NE. HHS Vulnerability Disclosure, Help Use of recombinant human bone morphogenetic protein-2 as an adjunct in posterolateral lumbar spine fusion: a prospective CT-scan analysis at one and two years. Literature on calcium sulphate products is limited to their use in lumbar fusion surgeries, with two level I94, 95, one level II96, and one level III97 studies included. Ceramics appear to be a promising group of bone graft extenders, especially when combined with bone marrow aspirates. Schuster JM, Avellino AM, Mann FA, et al. Volume 3, Issue 2, March-April 2003, Pages 155-165. Graham RS, Samsell BJ, Proffer A, et al. These substitutes are used in the treatment of bone defects, union or non-union surgeries, and spinal fusion in orthopedics. The main drawback is their limited strength. Graft options in posterolateral and posterior interbody lumbar fusion. ALIF, PLIF, TLIF, MIS) has not been investigated in clinical studies. Int J Nanomedicine. Data on the application of HA to scoliosis surgery is also limited to a single case series. Thalgott JS, Giuffre JM, Fritts K, Timlin M, Klezl Z. Instrumented posterolateral lumbar fusion using coralline hydroxyapatite with or without demineralized bone matrix, as an adjunct to autologous bone. Epub 2005 Apr 1. Their composition is similar to allograft. Your spine surgeon may use 1 type of bone graft or a combination in your surgery. B2A peptide on ceramic granules enhance posterolateral spinal fusion in rabbits compared with autograft. Gerszten PC, Tobler WD, Nasca RJ. J Spinal Disord. Lerner et al.77 randomized 40 patients with adolescent idiopathic scoliosis (AIS) into two treatment groups undergoing corrective posterior instrumentation; both groups were similar in terms of patient-related and procedure factors. Platelet Rich Plasma for Traumatic Non-Union Fractures: A Novel butControversial Bone Regeneration Strategy. Efficacy of rhBMP-2 versus iliac crest bone graft for posterior C1-C2 fusion in patients older than 60 years. Is INFUSE bone graft superior to autograft bone? Fusion is the most common technique in spine surgery and is used. Autologous iliac crest (AIC) graft has been considered the gold standard treatment for spinal fusion because of its histocompatible and non-immunogenic properties, presenting higher amounts. The growth can be attributed to the rising adoption of bone graft materials for spondylosyndesis. The basic idea is to fuse together painfulor unstable bones in the spine so that they heal into a single, solid bone. Epstein NE, Epstein JA. 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. The authors concluded that platelet concentrate had no consistent effect in promoting early fusion in cervical disc disease associated with significant degenerative changes. ABM consists of smooth, porous particles of pure deproteinated hydroxyapatite.190, 192 This bone graft combination of ABM and P-15, also known as i-Factor, is claimed to facilitate bone formation.192 I-Factor is indicated for use in skeletally mature patients for reconstruction of a degenerated cervical disc at one level from C3-C4 to C6-C7 following single-level discectomy for intractable radiculopathy. 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. Almost all of these reports supported the efficacy of rh-BMP-2 for increasing reliable fusion rates. Approximately 30% of the U.S. population reports back pain, of which 2% receive a diagnosis, and 65% get treatment. Porous Beta-Calcium Pyrophosphate as a Bone Graft Substitute in a Canine Bone Defect Model. 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. Dawson E, Bae HW, Burkus JK, Stambough JL, Glassman SD. Jones KC, Andrish J, Kuivila T, Gurd A. Radi-ographic outcomes using freeze-dried cancellous allograft bone for posterior spinal fusion in pediatric idiopathic scoliosis. There is little evidence on the efficacy of demineralised bone matrix for spinal fusion. Data on -TCP use for lumbar spine fusions is inconclusive in view of conflicting results reported across all evidence levels of studies. To date, autologous graft is the only biological substance demonstrated to possess osteogenic properties. The use of structural allograft for the treatment of residual spinal deformity and collapse secondary to tuberculous osteomyelitis was investigated in three different studies (level IV) by Govender et al.3941 The authors concluded that femoral, fibular and humeral allografts were all suitable alternatives to autologous tricortical iliac crest and rib grafts in treating spinal defects, with reported radiological fusion occurring in 94.2% to 100% of patients. Niu C-C, Tsai T-T, Fu T-S, Lai P-L, Chen L-H, Chen W-J. Bookshelf MeSH Sarwat AM, OBrien JP, Renton P, Sutcliffe JC. A single level II prospective study by An et al.43 evaluated the use of DBM (Grafton DBM) in combination with allograft for cervical disc disease. government site. Although initial clinical reports are promising, no recommendations can be made currently based on the limited data available regarding the use of B2A in spine surgery. Sohail Mirza. A prospective analysis of autograft versus allograft in posterolateral lumbar fusion in the same patient. Many bone graft substitutes, however, are not structural and need to be combined with a manufactured device that holds it . The spine journal : official journal of the North American Spine Society. Only studies reporting radiological fusion rates (assessed using X-rays, CT scans and/or isotope bone scans) and/or clinical patient outcomes following the application of bone substitutes in spine surgery were included. 1999-2022 Veritas Health, LLC. Spine Indication: patients with degenerative disc disease or trauma who require spinal fusion of 1 or more vertebral bodies and where conservative treatment has been unsuccessful. Burkus JK, Sandhu HS, Gornet MF, Longley MC. Over time, results with rhBMP-2 have been . Autograft bone is the most popular type of bone graft because it has no risk of disease transmission, and your body accepts the transplant well because the bone is coming from your own body. Accessibility Michael Fehlings reports no disclosures or conflicts of interest. Federal government websites often end in .gov or .mil. An official website of the United States government. Wenisch S, Stahl J-P, Horas U, et al. Fusion is the most common technique in spine surgery and is used to treat morbidities and relieve discomfort. Glassman SD. Aurori BF, Weierman RJ, Lowell HA, Nadel CI, Parsons JR. Pseudarthrosis after spinal fusion for scoliosis. The global spine market is $10 billion and growing in low single digits. The results were clinically comparable and not significantly different (p = 0.852). In this study involving un-instrumented fusions, radiologic pseudarthrosis was found in 33.3% of treated cervical levels in the allograft-DBM group versus 22% of levels in the autograft group (p = 0.23). Bone graft substitutes are widely used in the field of orthopedics and are extensively used to promote vertebral fusion. Baumann F, Krutsch W, Pfeifer C, Neumann C, Nerlich M, Loibl M. Posterolateral fusion in acute traumatic thoracolumbar fractures: a comparison of demineralized bone matrix and autologous bone graft. 2018 May;10(2):89-97. doi: 10.1111/os.12371. This was in contrast to the results reported in a previous prospective randomized pilot study involving 36 patients, by the same group of authors.164 Fusion rates reported in this study were 63% in the OP-1 group and 67% in the autograft group (p = 0.95), with no significant differences in Oswestry scores between the two (p = 0.56). 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.. Spinal Fusion Stimulates New Bone Growth. Careers. The graft material used in spinal fusion procedures can be generally categorized into three main types of materials: autogenous bone graft (autograft) from the patient's own body, allograft from human cadavers and/or living donors, and synthetic bone graft or substitutes (Table 1). Use of allografts for cervical fusions is supported in published literature for both anterior (level I, II, III, IV data) and posterior cervical fusions (level III, IV data). Graham et al.4 in a prospective randomized control trial (level I) comparing glycerol preserved versus freeze dried allografts for anterior cervical fusion reported fusion rates greater than 95% in both groups, which were not statistically different (p = 0.2127 and 0.1705 for the 3- and 6-month follow-up, respectively). Autologous bone has long been regarded as the gold standard for obtaining reliable spinal fusion, mainly because of its distinctive micro-architecture and biological properties, which provide the perfect blend of osteoconductive, osteoinductive and osteogenic elements. The Spine Journal. Autologous growth factors and platelet gels have failed to demonstrate any advantage in terms of fusion efficacy. During an autograft procedure, tissue is harvested from the patient s iliac crest, or possibly the distal femur or proximal tibia, and placed at the injury site. Jenis LG. Spine J. Some surgeries need large pieces of structural bone graft, which may cause problems in the area of the body where the bone was removed. Stevenson S, Emery SE, Goldberg VM. Ceramics work by providing a scaffold for bone growth and are predominantly osteconductive. The effect of bone graft extenders to enhance the performance of iliaccrest bone grafts in instrumented lumbar spine fusion. Materials (Basel). Reference: Spinal fusion is an operating process done to treat complications related to the bones of the spine. BMPs as a bone graft substitute are a fairly new development. ICD-10-PCS defines Fusion as joining together portions of an articular body part, rendering the articular body part immobile. Radiographs and CT scans were used to evaluate fusion at 6, 12 and 24 months. The authors concluded that ABM/P-15 has equal or greater efficacy at 6 and 12 months compared to autograft.191 Mobbs et al.196 (level IV) reported on a prospective analysis performed in Australia of a nonblinded cohort of patients who received i-Factor for an ALIF. Additionally, issues of sub-optimal bone quality in osteoporotic patients and donor site morbidity after graft harvest have compelled the orthopaedic community to look for other options. 2021 Jul;64(4):562-574. doi: 10.3340/jkns.2020.0331. Evaluation for fusion in coronal, sagittal, and axial CT cuts was performed by two radiologists. In contrast, five level IV studies6771 reported acceptable results with the use of -TCP in combination with autologous bone marrow aspirate for lumbar fusions. Numerous alternative bone graft substitutes are on the market or have been developed and proposed for application. Although it has successfully fused spines in animal studies, there is no proof that this is a powerful enough stimulus to successfully fuse a human spine; therefore, it is not recommended for use without the addition of the patient's own bone. Compared to rhBMP-2, the use of rhBMP-7 for other lumbar spine procedures (e.g. Corpectomy followed by the placement of instrumentation with titanium cages and recombinant human bone morphogenetic protein-2 for vertebral osteomyelitis. At first, bone morphogenetic protein referred to as rhBMP-2 was just used for single level spinal fusions. 1 - 3 however, the burden of donor-site morbidity from icbg harvesting is both a significant and common occurrence, which has significantly limited its use clinically. Use of recombinant human bone morphogenetic protein-2 as an adjunct for instrumented posterior arthrodesis in the occipital cervical region: An analysis of safety, efficacy, and dosing. Spine Deform. Clinical outcomes in all groups improved significantly overall; however the increment in outcome measures was not statistically superior for the rhBMP-2 groups in either study. The difference was statistically significant (p = 0.0217) between Groups 1 and 3, but not between Groups 2 and 3 (p = 0.1627).

Anterior cervical fusion with interbody cage containing beta-tricalcium phosphate augmented with plate fixation: a prospective randomized study with 2-year follow-up. Boden SD, Zdeblick TA, Sandhu HS, Heim SE. A roentgenographic evaluation of frozen allografts versus autografts in anterior cervical spine fusions. Silicate-substituted calcium phosphate ceramic bone graft replacement for spinal fusion procedures. a number of studies have demonstrated excellent fusion rates and clinical outcomes with the use of iliac crest bone autograft (icbg) in both lumbar and cervical fusion procedures. In another level I study, Thalgott et al.22 reported that, compared to frozen femoral ring allografts (FRAs), use of freeze dried FRAs for circumferential instrumented lumbar fusion was associated with a higher likelihood of pseudarthrosis (radiographic fusion rates 65.38% vs. 76.67% respectively assessed by periodic AP and lateral radiographs and CT at final follow-up) (p = 0.026). The use of these compounds in combination with autologous bone (either iliac crest or locally derived), allograft or ceramics has been studied in spine fusion procedures. Authors Ashim Gupta 1 , Nitin Kukkar 1 , Kevin Sharif 1 , Benjamin J Main 1 , Christine E Albers 1 , Saadiq F El-Amin Iii 1 Affiliation Use of rhBMP-2 in combination with structural cortical allografts: clinical and radiographic outcomes in anterior lumbar spinal surgery. Grossman W, Peppelman WC, Baum JA, Kraus DR. Three level IV studies157159 on the application of rhBMP-2 described excellent outcomes (100% fusion rates), and supported rhBMP-2 as a successful adjunct to fusion in pediatric patients. Knowledge of fusion biology is required to understand the benefits and limitations of these agents, which promote fusion via one of four mechanisms: osteogenesis, osteoinduction, osteoconduction, and osteopromotion. Trauma Int J Spine Surg. Invited submission from the Joint Section on Disorders of the Spine and P. Vaccaro AR, Patel T, Fischgrund J, et al. At 24 months follow up, the study group showed mean improvement in neck disability index (NDI) and arm pain scores superior to that of the control group (p = 0.03). doi: 10.3928/0147-7447-20020502-07. RhBMP-2 versus iliac crest bone graft for lumbar spine fusion: a randomized, controlled trial in patients over sixty years of age.
