Artificial disc replacement is a surgical procedure in which a degenerated disc in the spine is replaced with a mechanical device that substitutes as an artificial version in an effort to restore motion. 5 The disc replacement group retained an average of 7.9 degrees of flexion-extension at 24 months. ? Degenerative disc disease, a common cause of low back pain, occurs when one or more discs - gel-filled cushions between the bones . You Decide! If you are a patient suffering from neck or cervical disease, you should consult with a spine specialist with expertise in disc replacement to determine whether this procedure is right for you. This easily causes degeneration . Lumbar disk replacement is generally seen as an alternative to the more common spinal fusion surgery. Artificial disc replacement is only available to people who have relatively healthy spinal bones and are reasonably healthy. Its innovative design incorporates an artificial nucleus to allow shock absorption and a woven fiber annulus for graded variable motion resistance in all directions. Learning How Artificial Disc Replacement Fares over Time Though the disc fusion initially relieved the patient's pain, a . Cervical Artificial Disk Replacement Appointments 866.588.2264 Appointments & Locations Request an Appointment What is Artificial Disk Replacement? ACF, anterior corpectomy and fusion; C-ADR, cervical artificial disc replacement; ROM, range of motion. He recommended installing Paradigm Spine's Dynamic Stabilization System ("DSS") and then, in the same surgical session, removing my three diseased discs and replacing them with Synthes's ProDisc-L artificial discs possessing full mobility. There are some back issues for which it is not an effective treatment, but generally, if you meet the following guidelines, artificial disc replacement may be an option. Technically, there was a possibility that my spine would have to be fused at one of the three involved levels. Recovery Time after Artificial Disc Replacement. Prior to the development of ADR, spinal fusion was the principal treatment for painful degenerative disc disease that failed to improve with nonoperative management. Categories: Conditions, Spine Prev Post Next Post 2005, 30: E311-4. This is usually done when the existing disc has degenerated beyond repair and is posing a threat to the surrounding structures (nerves, vertebrae, etc. Fusion permanently joins 2 vertebrae together. Only 1 or 2 spinal discs are the source of your back pain. . Artificial disc replacement will not always be recommended. Because artificial disc replacement requires more access to your spine than a spinal fusion does, it can have a greater risk than spinal fusion surgery. DDD is when the disc loses height, bone spurs develop, degenerative instability takes hold, and often nerves get banged into causing pain. Recently, artificial cervical disc replacement (ACDR) has been widely accepted as a surgical alternative, with the potential to preserve motion and maintain normal sagittal alignment and balance at the instrumented segments [ 15 ]. Schedule an appointment by calling (239) 334-7000 or online by filling out this short contact form. Before artificial discs were available, patients would traditionally receive an Anterior Cervical Discectomy and Fusion (ACDF) procedure to alleviate the pain from a herniated disc. Faster Recovery Time - An artificial disc replacement option is generally less invasive than a fusion operation, which means reduced recovery time for the patient. Clinical outcomes As shown in Fig. The Promise of the ADR. Our surgeons can go beyond simple disc replacement or fusion to create a complete multi-level spine solution which can include combinations of the best disc replacment technology, stabilization, fusion, and other treatments, if needed. 3 Other risks include a need for supplementary surgeries in order to remove the implant or . Lumbar total disc replacement (TDR) has shown satisfactory clinical outcomes with few complications and reoperations at short-term follow-up, but the mid- to long-term results are not clear. This unique product is designed to mimic your spine's natural structure and movement, including backward and forward, side to side, up and down, and rotate left and right. The procedure itself was developed over time from the early 1900s as a means of limiting spinal deformity caused by infections of tuberculosis. Artificial disc replacement and fusion can relieve pain and dysfunction; however, the goal of surgery should also be to restore motion, and keep the patient active and functional. Artificial disc replacement, also referred to as disc arthroplasty or total disc replacement, is an alternative to spinal fusion that involves removing a damaged disc and replacing it with an artificial implant. Artificial discs are designed to replicate natural discs, so they help carry the load of your spine while still allowing for movement. Most artificial disk replacement surgeries take 2 to 3 hours. As shown in the Table 4, the mean total charge is $55,524 in total disc replacement group and $56,823 in fusion group ( P = .55). The real difficulty arises when choosing between disc replacement and extension of fusion. Spinal fusion is the traditional approach to degenerative disc disease and relieves pain by inhibiting movement. If you have ever broken a large bone, you probably had to wear a cast for many weeks until the bone healed. This prosthetic device is designed to maintain motion in the treated vertebral segment. The artificial disc was invented to stop the . In our patient, the disc replacement has worked well so far. The objective of this study was to evaluate the mid- to long-term clinical outcomes of artificial TDR for lumbar degenerative disc diseases. The evaluation was based on RASP and CASP scores reported by both patient groups. Artificial disc replacement can be performed using a minimally invasive approach with a very small incision or using a more traditional, open approach with a larger incision, depending on your needs. Understand this procedure is "off-label"what that means It is important for doctors and patients to be aware that using artificial discs in the way I have described is currently "off-label". I found a study that concludes: https://pubmed.ncbi.nlm.nih.gov/28816821/ ASD is adjacent segment disease, ACDF is a fusion. Opioids are only recommended for short-term use because of their risk for serious side effects, including addiction. Not only is recovery time shortened, but it is usually easier and less painful than recovery after spinal fusion (although both post-op care plans involve pain management . Patients have two options: Artificial cervical disc replacement Cervical fusion In 2007, the FDA approved the first artificial disc, the Prestige Cervical disc, which looks and moves much like the real thing but is made of metal. Cervical artificial disc replacement (CADR) can reconstruct intervertebral disc space height, . To compare the utilization of anterior cervical discectomy and fusion (ACDF) versus cervical disc arthroplasty (CDA) in terms of patient and hospital characteristics during the 3 years after Food and Drug Administration (FDA) approval of CDA devices in 2007. This may result in more wear and tear than normal. Lumbar disk replacement involves replacing a worn or degenerated disk in the lower part of your spine with an artificial disk made of metal or a combination of metal and plastic. Decades later . Ultimately, the goal of artificial disc replacement is to keep your spine functioning as it would in a normal, healthy state. Recently, Dr. Chi performed an ADR procedure on a patient who had previously undergone disc fusion (ACDF). After undergoing 3-level ADR with the M6-L disc, he has . This allows your surgeon to access your spine without moving the nerves. If a hybrid surgery is performed (fusion surgery at one level and artificial disc replacement at an adjacent level), the fusion will likely take 6 or more months to fully grow together. (2015) did a follow-up on ADR and lumbar fusion patients after 13.2 years (average) post-op. The artificial disc replacement may significantly reduce this risk. With surgical technology progress, ACDR has gained popularity. We conclude that L5-S1 motion segment can be preserved with artificial disc replacement in patients with previous long fusion for scoliosis surgery. Artificial cervical disc replacement; Cervical fusion; In 2007, the FDA approved the first artificial disc, the Prestige Cervical disc, which looks and moves much like the real thing but is made . With fusion there also is a possibility that the fusion of one part of the spine forces the discs and vertebra above and/or below to carry more load and motion. Currently 1- and 2-level artificial cervical discs are FDA-approved in the United States. Another potential advantage of artificial disc replacement is a more rapid return to activities than occurs after fusion surgery. Your surgical team will approach your lower back from the front through an incision in your abdomen. The ADR procedure is an alternative option to a Fusion surgery.During the procedure, a surgeon removes the impacted disc causing pain (typically in the lower spine or neck) and replaces it with an artificial disc. Spinal fusion provides internal structural support through using bone grafts, implants and/or pedicle screws, so that a direct, bony connection forms between the vertebrae that surround the painful discs. Surgery to implant an artificial disc also removes the damaged disc, but instead of using metal rods, screws and bone grafts to fuse bones together, the surgeon replaces the disc with an implant. Spine. Comparison of Total Disc Replacement with lumbar fusion: a meta-analysis of randomized controlled trials. In one case, it was a failed fusion or and in the other, the fusion had healed but the patient wanted greater range of spinal motion. In contrast, the average range of motion in the fusion group was 0.6 degrees at 24 months. Artificial disc replacement surgery is a motion-preserving surgery that, unlike an ACDF spine fusion, maintains movement in the patient's neck. "Surgery for ASD was performed after a mean period of 32 months from the primary ACDF. For some people with degenerative disease in the lumbar spine, artificial disc replacement (ADR) is superior in several ways to spinal fusion, according to a five-year study comparing the two surgical procedures. The M6-C disc is an innovative next-generation option for patients needing artificial disc replacement as an alternative to spinal fusion. For patients with 2-level disease, the charge analysis shows no significant difference between total disc replacement group and fusion group. Cervical artificial disc replacement surgery is a joint replacement procedure that involves inserting an artificial disc, such as the PRESTIGE Cervical Disc, between the vertebrae to replace a natural spinal disc after it has been removed. 1 Spinal fusion may help eliminate pain by stabilizing the spine and limiting pain-causing movements of one or more vertebrae. Tragically, many spinal fusion patients need follow-up surgical procedures after the spinal fusion, since fusing vertebrae together causes the neighboring vertebrae to suffer an unnatural amount of torque and strain. The device is made of metal plates with a ceramic or polymer core that flexes or glides. The benefit of an artificial disc is less stress on adjacent discs compared . Then he found Artificial Disc Replacement. Virginia Spine Institute is at the forefront of minimally-invasive disc replacement surgery. . In other words, if you have a fusion you have a 30 percent chance of having more surgery at a level above or below, whereas, if you have a disc replacement . This groundbreaking surgical method and advanced technology . ). It is most commonly performed to treat degenerative disc disease or post-laminectomy syndrome in patients who do . Patient Portal. Data consistently show that artificial disc replacement is safe and effective for the treatment of cervical disc degeneration with radiculopathy and/or myelopathy and demonstrates superiority over anterior cervical discectomy and fusion (ACDF) in both short-term and longer-term follow-up studies, he said. Unlike early Disc Replacement designs, the Spinal Kinetics M6 artificial disc is designed to replicate the structure and performance of a natural disc. . 972-608-5000. Read on to learn more about these two minimally invasive surgeries. More motion was retained after surgery in the disc replacement group than the plated group at the index level (p < 0.006 at 3, 6, 12, and 24 months). The goal of artificial disk replacement is to reduce pain and improve mobility in patients with cervical disk disease. During this procedure, your damaged disc is replaced with a prosthetic one that mimics the pliability of your natural disc. Artificial Disc Replacement. This in-dicates that, after interbody fusion, the motility of the fused segment is lost, with increase of stiffness, leading to increase of adjacent inferior intervertebral space stress. Conclusion: HS is superior to 2-ACDF; it leads to better NDI recovery, less postoperative neck pain, faster C2-C7 ROM recovery, and less adjacent ROM increase over a 2-year follow-up, but these benefits of HS become similar to those of 2-ACDF with 5 years of follow-up. Significant damage to one or more discs is often treated using artificial disc replacement. As with any other surgical procedure, there are risks associated with artificial disc replacement. Both fusion and disc replacement surgery are performed in patients with DDD ( D egenerative D isc D isease). Yajun, W., Yue, Z., Xiuxin, H., & Cui, C. (2010). The goal is to restore the natural motion of the spine, no fusion, no excessive removal of bone, no invasive screws, no risk to the delicate spinal cord or nerves! Total disc replacement (TDR, also called artificial disc) surgery is one of the latest advancements in spine surgery. Artificial disc replacements provide the benefits of improving range of motion and flexibility after surgery and potentially decrease the risk for additional issues and surgeries in the future. Abnormal bone formation may inhibit the mobility of an artificial disk. The spikes on the outer surfaces of the end-plates improve primary fixation until the bone has developed a solid bond to the disc. Summary of the evidence for each outcome. With this approach, the organs and blood vessels must be moved to the side. One advantage of cervical disc replacement over spinal fusion is that recovery is faster after replacement. Objective. 5 Conditions like DDD can cause the vertebrae of your spine to move poorly, be unstable, and absorb more load than normal, causing pain. The ESP disc prosthesis was designed for both lumbar and cervical disc replacement. Fusion or Disc Replacement? In a fusion surgery, the disc is removed and either a bone spacer or a plastic implant is placed in the disc space to restore disc height and remove pressure on the . They are made of 2 titanium alloy end-plates with an elastomeric core that provides cushion and functions like a real human disc. Because . Replacing the disc removes the cause. By definition, CASP . Summary of Background Data. 2 , the neck-pain VAS score before surgery was 6.961.77, and decreased gradually over the follow-up period (4.651.03 at 6 weeks; 3.301.06 at 3 months and 3.090.95 at 24 months). Artificial disc surgery replaces a worn-out disc in the spine with a device that moves like a natural disc. 10.1097/01.brs.0000164135.03844.b6. During the ADR procedure, the damaged disc is removed and replaced with an artificial one that moves and shifts like a real disc, preserving a patient's range of motion. The goal of disc replacement is to return the patient to an active high quality life. Unlike spine fusion surgery which decreases the range of motion by fusing two vertebrae, an artificial disc replacement is a motion-preserving surgery. However, for those who are candidates for ADR, the procedure restores or preserves spinal motion in ways that spinal fusion cannot. Cervical DiscReplacement VsFusion RecoveryTimes. Artificial disc replacement is an option for fusion revision These are just two of several patients I have successfully revised using artificial disc replacement. Artificial disc replacement is a motion-preserving procedure, which allows the spine at that level to move more normally after surgery. Because ADR surgery maintains movement, there is less stress on the patient's neck at spinal levels above and below the ADR implant. The artificial disc replacement offers painless motion to the injured cervical disc segment. ASD occurred after single level ACDF in 54% of cases, most commonly after C5/6 fusion (28%). Of the two lumbar artificial discs that are currently FDA approved, the Charite disc is the third modification of a device first developed in 1982 by Buttener-Janz and Schellnack at the Charite Clinic in the former East Germany and the ProDisc -L disc is the second generation of the device designed in the late 1980's by Marnay. This happens in both the neck and the low back. Bilateral pedicle fractures following anterior dislocation of the polyethylene inlay of a ProDisc artificial disc replacement: a case report of an unusual complication. The M6-C Artificial Cervical Disc. First, surgeons make a slit in the side of the neck and carefully move away any tissue. After fusion, the space between the spinal bones needs to heal completely. In a recent clinical study seven years after the surgery, artificial disc patients showed better scores than cervical spine fusion patients in the Neck Disability Index. Disc Replacement, developed in Germany over 20 years ago, is now the new gold standard, and has all but eliminated the debilitating tragedy of spinal fusion (except in the US, where this process has been slowed by regulation). Fusion patients have limited activities during the time required for the bone graft to grow into a solid mass. Comprehensive information about lumbar Artificial Disc Replacement (ADR), health insurance issues, rehabilitation resources, and ongoing recovery. Since then, several artificial cervical discs have been developed and approved. European Spine Journal, 19(8), 1250-1261. In this procedure, a damaged cervical disc is removed and replaced with a metal or polymer prosthetic. An artificial disc, which is also known as a disc prosthesis or spine arthroplasty, is made to mimic the the function and shape of a natural disc. Dr. Chang uses special instruments to carefully remove the damaged disc, then he inserts an artificial disc made of durable, biocompatible materials. CADR and discectomy groups. Artificial Disk Replacement Surgery A surgery that replaces damaged spinal discs with manufactured discs For people with significant back pain that makes it impossible to do simple activities Procedure is minimally invasive and involves shorter hospital stay Involves spine surgery, neurosurgery Overview What is degenerative disk disease? Artificial Disc Replacement In an artificial disc replacement, a spinal disc is removed and replaced with an artificial disc. It's an alternative to spinal fusion, which stops all motion at the disc. Fusion surgery can put additional stress on adjacent levels of the spine, which can sometimes lead to additional symptoms later on. 3 Spinal fusion has been a standard procedure for spinal conditions since the 1890s. Artificial disc replacement accomplishes this last feat, where fusion does not. We do this with next generation Disc Replacement Implants that offer many improvements over early disc replacement designs. A systematic search was conducted using the PubMed database to .
