C 34 Our study faced other limitations. The selection of bone graft material for a given procedure must balance the innate graft properties that promote fusion, the quantity of graft material required, and the risks associated with their use and harvest. Safe ways to lift, pull, or push objects are also covered. Osteoconductivity refers to the ability of the graft to serve as a scaffold for bone healing, allowing for the attachment, proliferation, and differentiation of osteogenic precursor cells. If a job is strenuous, it may take 6 months for the individual to return to work. https://doi.org/10.1046/j.1445-2197.2003.02748.x (2003). Typically, the complication rate for the anterior procedure is lower than for traditional spinal surgery. Numerous factors affecting fusion are directly controllable by the spine surgeon. Data were summarized in tables and further stratified based on bone graft types (AIC, ALG, ALP, [comprising hydroxyapatite, rhBMP-2, rhBMP-7, titanium cages], and LB). Bone grafting is a surgical procedure that uses transplanted bone to repair and rebuild diseased or damaged bones. I had an evidence of bone healing apparent on X-ray six weeks following surgery. This surgery involves the removal of a protruding disc from the spine for relief of pressure on the spinal nerves, followed by reconstruction. The site is secure. Park, J. J., Hershman, S. H. & Kim, Y. H. Updates in the use of bone grafts in the lumbar spine. Furthermore, our analysis of bone graft types revealed that LB presented a higher pooled proportional pseudarthrosis rate (10.5%). Ghogawala Z, Dziura J, Butler W E. Laminectomy plus fusion versus laminectomy alone for lumbar spondylolisthesis. Whang, P. G. & Wang, J. C. Bone graft substitutes for spinal fusion. The authors declare no competing interests. Incidence of neurologic complications has been reported at upwards of 30% in the immediate postoperative period, with the vast majority of cases being transient in nature. Associates M, Inc. 2014 spinal industry update. Choice of bone graft may also be altered, with greater consideration for use of iliac crest autograft if available. Lateral approach to the lumbar spine has been gaining in popularity. However, they can also increase points of load failure for each adjacent segment34, demand more grafts, and increase patients exposure to complications (due to an extensive surgical intervention). Graft materials and biologics for spinal interbody fusion. Kurd M F, Kreitz T, Schroeder G, Vaccaro A R. The role of multimodal analgesia in spine surgery. L2 and postoperative radiation therapy to the surgical site. Following the infiltration of inflammatory factors, the repair phase involves repopulation of progenitor cells at the hostgraft interface, with subsequent chondrogenic and osteogenic development, maturation of a collagen matrix, and ossification to form woven bone. Additional levels of fixation may be required for example, iliac instrumentation in long fusions extending to the lumbosacral junction. Site of arthrodesis may be the anterior column, performed by interbody technique. An additional option of bone graft extender is synthetic. Diagnosis of pseudoarthrosis is confirmed by imaging studies, often a combination of static and dynamic radiographs and computed tomography. Slim, K. et al. 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 of cancellous bone, growth factors, and pluripotent cells related to osteoinduction, osteogenesis, and osteoconduction8,9,10. 45 Res. Plast. Most patients are encouraged to stand and walk by the first day after surgery. National Library of Medicine Cunningham B W, Sefter J C, Hu N, Kim S W, Bridwell K H, McAfee P C. Biomechanical comparison of iliac screws versus interbody femoral ring allograft on lumbosacral kinematics and sacral screw strain.

Yonsei Med. Kornblum M B, Fischgrund J S, Herkowitz H N, Abraham D A, Berkower D L, Ditkoff J S. Degenerative lumbar spondylolisthesis with spinal stenosis: a prospective long-term study comparing fusion and pseudarthrosis. A minimally invasive spinal fusion uses a smaller cut (incision) than a traditional spinal fusion surgery. Bone graft refers to the use of bone in spinal fusion surgery. Presence of bilateral intertransverse bridging bone is indicative of a solid posterior arthrodesis ( Nonetheless, no radiographic gold standard is available with which to evaluate pseudarthrosis38 compared to open surgical exploration. Pseudarthrosis rates were not systematically assessed across the reviewed studies (AIC 17 of 51 analyses; ALG 4 of 9 analyses; ALP 6 of 20 analyses; and LB 5 of 10 analyses), which could have exacerbated the discrepancy between patient quantity and analyzed effects. Jt. Applying the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, this systematic review and meta-analysis identified 64 eligible articles. Ozgur B M, Aryan H E, Pimenta L, Taylor W R. Extreme lateral interbody fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion. Multiple studies have reported on the sensitivity (8589%) and specificity (6062%) of static radiographs in the assessment of a solid fusion. 15, 265271. There are three phases: inflammatory, repair, and remodeling. Due to an increase in medical devices availability nowadays, we compared these groups between them to evaluate the presence of differences or superiority in outcomes, such as fusion rate, hospital stay, follow-up extension (6, 12, 24, and 48months), pseudarthrosis rate, and adverse events. Analyses were performed by reorganizing studies according to graft material (with or without metallic implants) samples, resulting in 91 analyses (51 analyses regarding AIC, 9 analyses regarding ALG, 20 analyses regarding ALP, and 10 analyses regarding LB). Fischgrund J S, Mackay M, Herkowitz H N, Brower R, Montgomery D M, Kurz L T. 1997 Volvo Award winner in clinical studies. Rajaee S S, Bae H W, Kanim L E, Delamarter R B. Spinal fusion in the United States: analysis of trends from 1998 to 2008. Furthermore, access to the caudal levels (L5S1, occasionally L45) may be restricted by the pelvic brim. For our proportion analysis, we considered only events per patient. Goel, V., Weinstein, J. Doctors use bone grafts in the treatment of a variety of health issues, including fractures, bone infections, spinal fusions, tumors, and joint problems. Spine J. Park, D. K. et al. the contents by NLM or the National Institutes of Health. Healing time is how long it takes for the bone to become fully incorporated. Multiple surgical approaches are available to achieve fusion in the lumbar spine. , Stat. Arthrodesis is confirmed by observing solid bone bridging across the site of attempted fusion. Additional effects include inhibition of periosteal cell proliferation, increased cortisol production, decreased estrogen and calcitonin production, and a decrease in calcium absorption. Varying fusion rates of the lumbar spine have been reported and are dependent on the presence of instrumentation and surgical approach. Based on fusion rates and adverse events proportions, LB showed a superior trend among the graft cases we analyzed. 1 Grabowski, G. & Robertson, R. Bone allograft with mesenchymal stem cells: A critical review of the literature. Intermittent PTH (1-34) could be an appropriate adjunctive therapy for osteoporotic patients undergoing . With the advent of newer technologies and better instrumentation, your surgeon may be able to perform this surgery through a smaller incision in the front of your spine. Surgical treatment should be individualized to improve the chance of successful revision fusionsuch as optimizing the choice of graft material, surgical approach, and biomechanical fixationwithin the limits of surgical risks and surgeon comfort. 1 is a flowchart describing our database research, which identified 1535 studies. The resulting cantilever moment may result in early failure. This size discrepancy could explain the LB fusion effect among our pooled samples, which could exacerbate LBs effect. HHS Vulnerability Disclosure, Help All material on this website is protected by copyright. Simmonds M C, Brown J V, Heirs M K. Safety and effectiveness of recombinant human bone morphogenetic protein-2 for spinal fusion: a meta-analysis of individual-participant data. Other imaging modalities have also been described, such as magnetic resonance imaging (MRI), ultrasonography, and technetium-99m bone scan, but these modalities are not recommended for the assessment of fusion status following spine surgery. For all databases, controlled vocabulary and text word searches were performed, using a combination of the keywords: spinal fusion AND autograft AND spinous process, spinal fusion AND autograft AND spinal lamina, spinal fusion AND autograft AND iliac crest, spinal fusion AND heterograft, spinal fusion AND allograft AND spinous process, spinal fusion AND allograft AND spinal lamina, spinal fusion AND allograft AND iliac crest.

Demineralized bone matrix (DBM) is a form of allograft produced by acid extraction of bone, removing the mineral phase and leaving a matrix of collagenous and noncollagenous proteins. Albee F H. Transplantation of a portion of the tibia into the spine for Pott's disease. Fritzell P, Hgg O, Wessberg P, Nordwall A. Electric stimulation in the postoperative period has been used to augment fusion. Unsurprisingly, and as we have mentioned, foreign bodies can carry some inherent risks, which could explain ALPs higher pooled proportional rates of infection (10.2%) and graft-related events (35.1%). The findings of our analysis demonstrate substantial variety of spinal grafts and the need for more rigorous studies to better address and assist surgeons in choosing the best graft options. How to Prepare What to Expect What is lumbar fusion? The authors concluded that smoking cessation reverses the negative impact of smoking on spinal fusion. Spine J. The greatest surgical risk is vascular. In some cases, this may be done through the same incision. Who is a candidate? 1999-2023 Veritas Health, LLC. Multimodal pain regimens following orthopaedic surgery of the lower extremities have become routine, but their use after spine surgery has been more limited. More recently, the safety profile for use of BMP-2 has come under closer investigation. An interbody fusion can be performed using different approaches. While the fusion is growing together and strengthening, these movements should continue to be avoided to prevent stress at the fused segments: See Practical Advice for Recovering from Back Surgery. Other common sources of autograft include local bone (for example, laminectomy bone), rib, or fibula. Is Minimally Invasive Spine Surgery Right for You? Apart from distinct assessments during patients clinical courses, such as weight and height (in preoperative assessments) and Odoms criteria (in postoperative assessments), pre- and post-operative assessments included matching analysis only for Japanese Orthopedic Association Score (JOA) and Nurick Grade reports in the AIC group. 15 Technique of fixation may need to be altered. Transpsoas approach (TP) (lateral lumbar interbody fusion [LLIF], extreme lateral interbody fusion [XLIF]) 10. In a systematic review, Bodalia et al reported a 92.3% fusion rate with BMP-2, with a faster time to union when compared with bone graft alone. 1999-2023 Veritas Health, LLC. Spine J. A substitute replaces an ABG and presents the same or higher healing success rates compared to ABG alone17,18. Choudhri T F, Mummaneni P V, Dhall S S. Guideline update for the performance of fusion procedures for degenerative disease of the lumbar spine. Considering the data inconsistencies in our primary analysis, which precluded further associations (e.g., fusion rategraft typesurgical technique), we performed a subgroup analysis of fusion rates with or without metallic implants. Substantial heterogeneity is defined as50%24. Quillo-Olvera J, Lin G X, Jo H J, Kim J S. Complications on minimally invasive oblique lumbar interbody fusion at L2-L5 levels: a review of the literature and surgical strategies. The basic idea is to fuse together the painful or unstable vertebrae so that they heal into a single, solid bone. PubMed 37 12 3During the inflammatory phase, a hematoma is formed around the fusion bed, with resulting infiltration of macrophages, polymorphonuclear cells, and fibroblasts. Swedish Lumbar Spine Study Group . 43. Addition of anterior, transforaminal, or posterior interbody technique to rigid fixation increases the fusion rate to 88 to 100%. ) Staged revision was performed, with posterior instrumentation removal and osteotomies, anterior corpectomies of L2 and L3 with reconstruction, anterior lumbar interbody fusion at L5S1, and posterior instrumented fusion T10pelvis with use of rhBMP-2. & Altman, D. G. Measuring inconsistency in meta-analyses. The goal is to join together consecutive motion segments for the purpose of stabilizing an unstable spine. There are three phases: inflammatory, repair, and remodeling. However, for most the full recovery process takes somewhere between three to six months. Glassman S D, Anagnost S C, Parker A, Burke D, Johnson J R, Dimar J R. The effect of cigarette smoking and smoking cessation on spinal fusion. 2020, 8361798. https://doi.org/10.1155/2020/8361798 (2020). In particular, the evidence linking cigarette smoking and pseudarthrosis is very strong, and it has been clearly demonstrated that nicotine inhibits the bone growing cells (osteoblasts), which are necessary to achieve a successful spine fusion. Med Times and Register. In general, it takes at least three months to get a solid fusion, and it can take up to a year after the spine surgery. Lumbar spinal fusion is a commonly performed procedure to stabilize the spine, and the frequency with which this operation is performed is increasing. There are a number of factors that can affect this outcome after spine fusion surgery. Sixty-four studies were identified. Award Winner It is essentially a welding process. Clin. Spinal fusion surgery which was combined with perioperative RT showed relatively low bone fusion rate (57%). 71, 3948 (2013). Spine J. In an anterior lumbar interbody fusion, the intervertebral disk is removed. An osteotomy is a bone-cutting procedure to realign and reshape your bones and joints. Pain is likely to continue to decrease gradually, but some patients continue to have pain 3 to 6 months after surgery. The KruskalWallis test was used to compare variables among the four groups, andpost hocanalyses using MannWhitneyUtests were performed to compare two groups. AIC pain corresponded to a 23.4% pooled proportional rate and a significant proportion of donor site morbidity (23.2%), corroborating the previously mentioned graft drawbacks already described in the literature11,12,13,14,15,16. Passage of an electric current results in increased collagen synthesis and fibrocyte recruitment to the fusion site. This is crucial since if it is possible to avoid using AIC, or other nonlocal bone, the post operatory morbidity, especially residual pain and an extra wound/scar, can be avoided. Inclusion in an NLM database does not imply endorsement of, or agreement with, 9, 623629. Because this approach uses a smaller incision, there may be less chance of muscle and nerve damage.

Although most spinal surgeries are performed using a posterior (back) approach, your surgeon may choose an anterior approach for a number of reasons, including: In contrast to a posterior approach to low back surgery, an anterior approach enables the surgeon to access your spine without moving the nerves. Our study aimed to evaluate differences in outcomes of patients submitted to spinal fusion using different grafts measuring the effectiveness of spinal fusion rates, pseudarthrosis rates, and . Biology of Bone Healing. The global bone grafts and substitutes market size was valued at $2,586.30 million in 2021, and is projected to reach $4,005.26 million by 2031, growing at a CAGR of 4.5% from 2022 to 2031. . For bones to fuse or heal together, additional bone is needed. Sci Rep 12, 7546 (2022). For successful bone fusion, the selection of bone graft was the most important. Furthermore, we did not include all available ALP grafts due to the high existent variability, which could wane proportional analysis. There is no appropriate time start again. Access to the lumbar spine may also be obtained from an anterior or lateral approach. Decortication allows for local marrow stimulation and release of osteoinductive proteins and an adjunct blood supply; this must be counterbalanced against overzealous technique leading to thermal necrosis at the graft site. Thoracolumbar junction is particularly vulnerable to failure given the biomechanical transition from rigid, kyphotic thoracic spine to mobile, lordotic lumbar spine.

PubMed Central Bone healing and spinal arthrodesis occur similarly. More recent studies have shown similar results in fusions performed for degenerative lumbar disease, with successful arthrodesis in 84 to 92% in posterior lumbar fusion with rigid instrumentation. It is important not to attempt to rush your recovery as the bone graft requires time to heal and immobilize the portion of your spine. JAAOS Glob. The fusion bed is typically through the facet joints and intertransverse gutters, often supplemented with posterior pedicle screw instrumentation. Glob. Spine fusions have become a frequent treatment choice for distinct spinal pathologies over the past four decades. 9 Preferred reporting items for systematic reviews and meta-analyses: The PRISMA statement. Reproduced from Flatow E, Colvin AC (eds. Mobbs R J, Phan K, Malham G, Seex K, Rao P J. Lumbar interbody fusion: techniques, indications and comparison of interbody fusion options including PLIF, TLIF, MI-TLIF, OLIF/ATP, LLIF and ALIF. However, the surgeon must move organs and blood vessels to the side when using an anterior approach. Mardones R, Quezada F (2007) The effect of ketoprophen on lumbar spinal fusion healing in a rabbit model. For example, the surgeon can access the spine through incisions in the lower back or through incisions in the front of the body. Bone graft from an autologous source is the only graft material with osteogenic potential ( Google Scholar. However, our review revealed highly heterogeneous data and a need for more rigorous studies to better address and assist surgeons choices of the best spinal grafts. Google Scholar. FOIA An enhancer is a material combined with ABG to increase successful fusion rates compared to ABG alone17,18. Relat. Anterior to psoas approach (ATP) (oblique lateral interbody fusion [OLIF]) allows oblique access to the disc space with posterior retraction of the psoas muscle. Ann. Fig. According to applied grafts, pseudarthrosis achieved a significantly lower pooled proportion in ALG studies (four events among 243 patients, 4.8% CI 0.115.7, I2=77.3%) compared to AIC studies (81 events among 851 patients, 8.6% CI 4.214.2, I2=84.0%), ALP studies (14 events among 153 patients, 7.1% CI 0.918.2, I2=78.3%), and LB studies (18 events among 154 patients, 10.3% CI 1.824.5, I2=81.7%). A total of 64 studies (4177 subjects) were selected for this systematic review. Like any other surgical intervention, spine fusions can lead to unexpected outcomes, such as pseudarthrosis or other adverse events. Funding 5 This spacer, or cage: After the cage is placed in the disk space, the surgeon may add stability to your spine by using metal screws, plates, and rods to hold the cage in place. with the majority being posterior or transforaminal lumbar interbody fusions, or posterolateral lumbar fusions. D He specializes in spine surgery and has been practicing for more than 25 years. Your incision may be horizontal or vertical, and either in the middle or off to the side depending on how comfortable your surgeon is in accessing the spine. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement20. When multiple follow-up periods were available for a study, data from the last assessment were used for the combined analyses. E This promotes bone healing and helps make the fusion happen. B https://doi.org/10.1016/j.bone.2010.05.029 (2010). PubMed Central 284, 8090 (1992). Systemic factors may also promote bone healing, such as growth hormone, thyroid hormone, parathyroid hormone, and estrogens. Fig. In a cadaveric study, Cunningham et al reported long fusions above L3 significantly increased the strain on S1 screws and recommended supplemental fixation with iliac screws. Disc space access via anterior or lateral approaches (ALIF, TP, ATP) is more extensive than through posterior techniques (PLIF, TLIF) and allows for placement of graft material spanning a wider surface area. 29, 296303. 21 The recovery time for spinal fusion surgery can vary from one individual to the next, depending on a variety of factors including age, health, and weight. Summary Intermittent treatment with high-dose parathyroid hormone (PTH) enhances the quantity and quality of the fusion callus and reduces healing time of posterolateral spinal fusion with autologous iliac bone grafts in ovariectomized osteoporotic female Sprague-Dawley rats. Other than an increase in screw diameter or length, fixation from an alternative approach (anterior or lateral), or using an alternative technique (such as cortical bone trajectory) should be considered. Alloplastic pooled proportional rate for spinal fusion. This is a favorable fusion environment where the graft is placed under compression. Orthopedics 32, 23 (2009).

To fuse the spinal bones, the surgeon places the bone graft material between the bones. 5 Data were inconsistent across studies since none of the ALG articles specified hospital LOS. https://doi.org/10.1097/MD.0000000000011169 (2018). Kim, D. H. et al. One frequently used alternative is local bone (LB), however, to our best knowledge, previous studies have only compared autologous bone graft with ALP and ALG. Spinal fusion surgery is a commonly performed procedure, both in the United States and around the world. Meta-analysis of proportions, using MedCalc 16.2.0, was performed to estimate an overall weighted proportion and its 95% confidence interval (CI) for each outcome of interest. Comparing the inputs of more than three decades of medical evolution is challenging, given technical improvements, instrumental variations, and a greater range of material. Posterior fusions may be performed via open or minimally invasive techniques (MI-TLIF). After passing a screening phase, 184 studies were fully reviewed, leading to 120 exclusions that are detailed in Supplementary Table 1. Formica, M. et al.

It is generally stored in fresh frozen or freeze-dried forms. 1 Get the most important science stories of the day, free in your inbox. Kinsella J, Moffat A C, Patrick J A, Prentice J W, McArdle C S, Kenny G N. Ketorolac trometamol for postoperative analgesia after orthopaedic surgery. Spinal fusion is a treatment option when motion is the source of pain the theory being that if the painful vertebrae do not move, they should not hurt or when there is excessive motion in the spine due to arthritis, or from trauma or a fracture. et al. but its use after spine surgery has been associated with pseudoarthrosis in a dose-dependent manner. Overall, patients main diagnoses for surgical intervention were degenerative diseases (78.8%). 14 If an interbody fusion was performed, then bony bridging may be seen across the disc space. In other cases, however, your surgeon may need to insert additional screws into the back of your spine through a separate incision in your back (posterior approach). One of the risks of any spine fusion surgery is a lack of healing of the bone graft, which is known as a pseudarthrosis. Zdeblick T A. A functional outcome study. 32 With autograft, it takes about 6 weeks. Fig. An example is the platelet rich plasma, which is gaining recognition as an important adjunct in the spinal graft market39. Orthop. Bone graft and bone graft substitutes in spine surgery: current concepts and controversies. Sabrina Araujo de Frana. 44 An official website of the United States government. Boehm, K. S. et al. There are many surgical techniques and variations of techniques. ). Detailed information about rates and confidence intervals are presented in Supplementary Table 4. 6, e1000097. For randomized controlled trials, each domain was classified as unclear bias, low RoB, or high RoB. All of these factors should be taken into account in the formation and implementation of a surgical plan. ALP and AIC studies described significantly more cases of adverse events (80 events/404 patients and 860 events/2001 patients, respectively) compared to LB (20 events/311 patients) and ALG (73 events/459 patients). primarily affecting the repair phase of bone healing. ). Thank you for visiting nature.com. The effect of nicotine on gene expression during spine fusion. Preliminary results. Alternatively, fusion may be performed via a posterior approach. https://doi.org/10.1097/00003086-197905000-00039 (1979). Structured clinical trials are highly encouraged to promote the availability of optimal, costbenefit treatments for patients. ALP and AIC studies described significantly more cases (80 events among 404 patients and 860 events among 2001 patients, respectively) than LB studies (20 events among 311 patients) and ALG studies (73 events among 459 patients). As pain gradually alleviates and the energy level rises, it is good to gradually increase activity levels. Data were partially (one graft-type group of interest) or fully (all graft-type groups in the study) extracted from comparative studies, in accordance with our inclusion criteria.

Systemic steroids inhibit the inflammatory phase of bone healing and the differentiation of progenitor cells, and decrease synthesis of extracellular matrix. 6 Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Biomechanical loading of the sacrum in adolescent idiopathic scoliosis. Recombinant human bone morphogenetic protein2 (rhBMP-2) is a synthetic protein with strong osteoinductive properties that has been used as an alternative to autologous bone graft in spinal fusion. Part 4: Radiographic assessment of fusion status. Fig. For example, Choudhri et al.38 recommend CT imaging with fine-cut axial and multiplanar reconstruction to evaluate spinal fusions. During this time period of about 1 to 3 months after the surgery, the lumbar fusion bone mass is becoming established. 4) study groups. Silvestre C, Mac-Thiong J M, Hilmi R, Roussouly P. Complications and morbidities of mini-open anterior retroperitoneal lumbar interbody fusion: oblique lumbar interbody fusion in 179 patients. Local nonsurgical factors may influence fusion rate, such as prior radiation treatment, but may not be optimizable. General-Feature ArticleMultilevel Spinal Fusion However, allograft (ALG) and alloplastic (ALP) grafts are foreign bodies that carry some inherent risks. In an anterior approach, organs and blood vessels are moved to the side to expose the disk space. The quality of eligible studies and their risk of bias (RoB) were examined by two reviewers (SAF and ASMS) using the methodological index for nonrandomized studies (MINORS)21, and the Cochranes collaboration tool for assessing RoB22 in randomized controlled trials. Zdeblick reported 65% successful arthrodesis without instrumentation, increasing to 77% with semirigid instrumentation, and 95% with rigid instrumentation. One particular class of agent, NSAIDs, act through the inhibition of cyclooxygenase (COX), with resulting inhibition of prostaglandin formation. Martin C. Jordan, Hendrik Jansen, Timo M. Heintel, Pietro Feltri, Luca Solaro, Giuseppe Filardo, Hsuan-Kan Chang, Jason Ku, Shih-Ming Hsu, Nikola Stokovic, Natalia Ivanjko, Slobodan Vukicevic, Guo-ye Mo, Teng-peng Zhou, Shun-cong Zhang, Ann-Kathrin Joerger, Ehab Shiban, Bernhard Meyer, Jian-cheng Peng, Hui-zhi Guo, Yong-chao Tang, Scientific Reports from the American Academy of Orthopaedic Surgeons, Increases the collapsed intervertebral disk space, To avoid multiple surgeries in one area if you have already had previous spinal surgeries using a posterior (back) approach, To allow more direct access to the intervertebral disk, To have the ability to add more lordosis (swayback) to your spine. Adequate pain control following lumbar spinal fusion may be challenging. Unfortunately, spinal fusions with AIC have been associated with several morbidities, such as a higher incidence of infection, donor site pain, hematoma development, increased operative time, and blood loss11,12,13,14,15,16. volume12, Articlenumber:7546 (2022) Nevertheless, our literature review examined a limited sample for this subgroup analysis, and it included many studies with moderate to high heterogeneity, reflecting pseudarthrosis evaluations diversity. Direct current stimulation (DCS) requires intraoperative placement of electrodes in contact with the fusion mass. This site is for educational purposes only; no information is intended or implied to be a substitute for professional medical advice. Retrospective studies, prospective analyses, randomized clinical trials, and case series were included in this review. Excess lifting (anything over 10 to 15 pounds). J. Allograft bone does not contain live cells and provides only osteoconductive and osteoinductive potential. Grafts such as -tricalcium phosphate provide only a mechanical scaffold and are solely osteoconductive. PubMed Article Common causes of instability include degenerative, traumatic, metastatic, or infectious. may have a higher rate of nerve injury, particularly at more caudal levels. Dr. Sherman has served as Assistant Professor in the Department of Orthopaedic Surgery at the University of California, Los Angeles and has conducted research on motion preservation technology and minimally invasive spine surgery. Posterior approach is the workhorse for lumbar spinal fusion and allows ready access and rigid fixation over multiple spinal levels. Ribeiro-Junior PD, Nary-Filho H, Matsumoto MA (2013) Cyclooxygenase-2 inhibition does not impair block bone grafts healing in rabbit model Fig. 22 https://doi.org/10.1371/journal.pmed.1000097 (2009). They found a nonunion rate of 26.5 and 14.2%, respectively. Fine cut axial CT scan with coronal reconstruction confirms failure of fusion at L34 ( The popularity of BMP has grown over the past two decades, with a variety of on- and off-label indications. The same pattern was observed in the LB group (Frankel scale report) and ALP group (Frankel and JOA reports), as Table 3 shows. In interbody fusion, the intervertebral disc or a complete vertebra is removed and replaced with bone graft. 8, 396412.
