Roberto Gazzeri, Marcelo Galarza, Claudio Fiore, Andrea Faiola, Fabrizio Puzzilli, Giorgio Callovini, and Alex Alfieri report no, conflict of interest concerning the materials and methods used in, this study or the findings specified in this paper. Exported major MeSH terms were further biclustered with gCLUTO according to co-word analysis. Conservative treatment was provided to seven patients who experienced aggravated lumbocrural pain even though their devices remained in the correct position, and pedicle screw treatment was used as an alternative in four cases. Percutaneous interspinous devices (PIDs) are a recently-developed, minimally-invasive, alternative treatment option. Under strict indications, topping-off surgery is an acceptable alternative to fusion surgery for the treatment of two-segment lumbar disease. The key points to ensure surgical effect and to reduce non-device-related complications are mastering surgical indications and thorough intra-operative decompression. There are several types of spine surgery. No revision was documented in the coflex(®) and one in the decompression group (2.0 %). Design Randomized controlled trial. 1 226 screws were implanted in the lumbar vertebrae, including 1 196 grade-I screws (accuracy 97.2%). The median age of the patients included in the population was 50.9±10.7 years with a median BMI of 24.8±11.4 kg/m2. On the basis of the development of bony erosion around Coflex, patients were divided into the erosion group (n = 14) or the nonerosion group (n = 16). The only other study is a preliminary report of only 10 patients with variable intervals of clinical outcome assessment. Materials and methods Seventy percent of the patients were satisfied with the surgical outcome. Os bloqueios costumam dar melhores resultados no alívio dos sintomas de ciatalgia e menos no quadro de claudicação neurogênica. Conclusion: There was a total of 1 revision case with removal of INSPAN and open hemilaminectomy decompression. The related complications were reported, and appropriate measures were taken. The purpose of this study was to quantify the intra- and postoperative complications of an interspinous process device (Coflex) in managing degenerative lumbar diseases and to investigate corresponding therapeutic strategies. Mid-long term follow-up efficacy and safety between topping-off and fusion were similar, while topping-off reduced the rate of ASD. As with any new treatment, appropriate attention must be given to strict surgical indications and proper patient selection. We included only the patients completed minimum 24 months follow up evaluation. In medical research over the last few years, it has been proven conclusively that not only do smokers have a higher incidence of back pain; but when they do undergo surgery for back problems, they have a 15% higher failure rate. The Visual Analogue Scale and Oswestry Disability Index scores showed evident improvement in these patients. Among them, six cases were found with surgical technique-related complications, including device-related complications in three cases: spinal process fracture (n = 1), Coflex loosening (n = 1), fixed-wing breakage (n = 1), dura mater tear in two cases and superficial wound infection in one case. Each motion segment was tested in compression, then flexion/extension, then lateral bending, and then axial rotation at five conditions: 1) intact; 2) partial destabilization (by cutting the supraspinous and interspinous ligaments, the ligamentum flavum, the facet capsules, and 50% of the inferior bony facet bilaterally); 3) stabilization with the Coflex device; 4) complete destabilization with total laminectomy; and 5) stabilization with pedicle screws and rods. The ultimate failure rate requiring additional surgery was 9.6%. Study supervision: Gazzeri. Elderly, age over 60 years, at Wanasraya nursing home Denpasar on January 2015 recruited to this study. With the development of surgical techniques, both topping-off technique and PLIF are safe. The Visual Analogue Scale and Oswestry Disability Index scores of two patients who underwent revision were also improved. Get answers for all the most frequently asked questions regarding what to expect with a Mobi-C Cervical Disc replacement procedure and recovery time. The ODI changed from 44.34 preoperatively to 14.62 postoperatively, and 80% of group B patients achieved excellent and good Macnab outcomes. The results of this prospective observational study indicate that X Stop offers significant short-term improvement over a 1-year period. described 69 cases in which an X-Stop de, implanted, and the main complications were spinous pro, tion of the interspinous space with a large interspinous, est distraction and adequately sized device are needed to. Results: Topping-off technique was more effective in improving subjective feelings of patents rather than objective motor functions. Methods: Admitted published papers were obtained from Web of Science Core collection and PubMed database. One-year follow-up evaluation revealed positive good results in the 83.5% of patients treated with IPD with respect to 50% of the nonoperative group cases. In 12 patients with 17 distracted levels, the area of the dural sac at these levels increased from 77.8 to 93.4 mm after surgery in the standing position (P = 0.006), with increase in the exit foramens, but no change in lumbar posture. TLC XL has the same properties as standard CoFlex ® TLC, but has an additional 2 yards on each roll for larger limbs. The X STOP implant is a titanium alloy device that is placed between the spinous processes to reduce the canal and foraminal narrowing that occurs in extension. The perioperative lumbar MRI data were processed for 3D-volumetric analysis. The authors developed a simple classification for defining HO and compared HO-positive and HO-negative cases to identify possible risk factors. This was a retrospective study using prospective multicenter Food and Drug Administration Investigational Device Exemption (FDA IDE) trial (Superion™ and X-STOP®) data. The force data were independent of implant size, diagnosis (with one exception), number of levels of the decompression procedure, number of levels of implantations (one or two), and follow-up time. Nerve Root Sedimentation Sign: Can It Predict the Success for Surgical Intervention in Patients With Symptomatic Lumbar Spinal Stenosis? The leader project, Prof. Dr. M. Galarza y Vicentini, stands with the support of outstanding professionals such as: Prof. Dr. José María Amigó and Prof. Dr. Ángel Giménez (Centro de Investigaciones Operativas UMH), as well James P. (Pat) McAllister, PhD, Professor of Neurosurgery and Bioengineering, Director of Basic Hydrocephalus Research, University of Utah, USA; Prof. Dr. med. Coflex, a type of interspinous process implant, can provide intervertebral dynamic stability for surgical segments and effectively relieve lumbocrural pain. A large number of interspinous process devices (IPD) have been recently introduced to the lumbar spine market as an alternative to conventional decompressive surgery in managing symptomatic lumbar spinal pathology, especially in the older population. We do not recommend the X-Stop for the treatment of spinal stenosis complicating degenerative spondylolisthesis. Q: Am I a candidate for the coflex ® procedure? I had a herniated disc at l4 l5 for about a year and half, locked my back up and throw out all my muscles at my hip and left leg. The ABC scale with cut off 82.9% has significantly association with falls; p = 0.01; prevalence ratio = 7.0; 95%CI 1.6 – 49.8. It is being done by a neurosurgeon, I've talked with a couple people who have had it done there and are pleased. Background: Spinal stenosis is a common elderly disease, present in a variety of forms. Individual successes have to be attributed to conservative treatment or placebo effects. The angle between the Coflex arms was measured for each radiograph and statistically evaluated. Hsu KY, Zucherman JF, Hartjen CA, Mehalic TF, Implicito, drashov D: A novel technique of intra-spinous proc, for lumbar spinal stenosis: a 4-year follow-up study, 20. Ten consecutive elderly patients with LSS were assessed postoperatively by magnetic resonance imaging and the Swiss Spinal Stenosis Questionnaire. the aim of these devices is to unload spine, restoring foraminal height, and stabilize the spine by distracting the spinous processes. A total of 92 screws were implanted in the cervical vertebrae, including 90 grade-I screws (accuracy 97.82%). Results For example, Weinstein and Malmivaara [10, 11] reported a complication rate of 17–24% in the standard bony decompression operation cohorts. Interlaminar stabilization offers greater biomechanical advantage compared to interspinous stabilization after lumbar decompression: a finite element analysis, Is the Interspinous Device (Coflex) Outdated in the Treatment of Lumbar Spinal Stenosis? Conservative treatment can be provided to patients with symptoms if the device remains in the correct position; however, revisions and salvages should be undertaken with internal fixation of pedicle screws for patients with device malposition, intraoperative implantation failure, or device intolerance. We evaluated patients with spinal stenosis and degenerative disc disease who were treated with open decompression and distraction of the spinous processes at L4-L5 using an interspinous device. The X Stop Interspinous Process Distraction Device is a relatively new interspinous implant designed for patients with symptomatic spinal stenosis particularly neurogenic claudication. Rates of proximal RASD (P = .001) and CASD (P = .03), postoperative VAS-B (P = .0001) were significantly lower in topping-off group than that in PLIF group. The disc height and foraminal area on radiographs also increased significantly, but with limited effects up to three months postoperatively. Eight complications were recorded: 4 device dislocations and 4 spinous process (SP) fractures, including 2 spontaneous fractures of the L4 SP in patients treated at L3-L4 and L4-L5. In all cases, in this series, plain radiographs were inadequate to identify fractures because all fractures were initially minimal or nondisplaced, many patients were osteopenic, and the metallic wings of the devices often obscured fractures. The purpose of this study was to compare the efficacy of IPD with nonoperative treatment in patients with NIC secondary to degenerative spondylolisthesis. Background: Interspinous implants aim to restrict painful motion while otherwise enabling normal motion; the devices (spacers) distract the spinous processes and restrict extension. Previously, a randomized study has shown a 75% improvement in symptoms and physical function at 1-year post-X Stop implantation for lumbar spinal stenosis. Methods: Revision, reoperation rates for IPD range from 4.6% to as high as 85% in studies. © 2008-2021 ResearchGate GmbH. Only patients with a minimum follow-up of 2 years were included. METHODS All rights reserved. Despite the fact that they are composed of a wide range of different materials including titanium, polyetheretherketone, and elastomeric compounds, the aim of these devices is to unload spine, restoring foraminal height, and stabilize the spine by distracting the spi… Committed to delivering a higher standard, RTI’s implants are used in sports medicine, general surgery, spine, orthopedic and trauma procedures and are distributed in nearly 50 countries. Statistically significant improvement in ZCQ and SF-36 scores was seen in X STOP device-treated patients but not in the nonoperative control patients at all postoperative intervals. evaluated the limitations and failures of interspinous spacers, ... Porém, nos últimos anos, revisões sistemáticas e metanálises têm questionado os resultados obtidos, e a North American Spine Society considera que não existem evidências suficientes para indicar a sua utilização, sendo considerada uma técnica ainda investigacional. High failure rate of the interspinous distraction device (X-Stop) for the treatment of lumbar spinal stenosis caused by degenerative spondylolisthesis. The accuracy of pedicle screw insertion was rated as grade I in 1 068 screws (98.2%) according to postoperative CT scan. Find answers to your questions on insurance, finding Mobi-C surgeons, and its history of use. Preoperatively, careful attention should be paid to bone density, appropriate implant size, and optimal patient selection. Methods: Further, the TAU model exhibited less compensation at adjacent levels than the PSF model in terms of ROM, IDP, disc stress, and facet loads, which may lower the incidence of the adjacent segment disease (ASD). The study analyzed biomechanical parameters assuming that the implants were perfectly fused with the lumbar spine. The ODI changed from 50.25 preoperatively to 18.2 postoperatively, and excellent and good Macnab outcomes were obtained in 78% of patients. Thirty-seven studies were included from 2011 to 2016. Es wird auf eine große kontrollierte, prospektive, randomisierte Studie gewartet, die an 7 Zentren in Deutschland durchgeführt wird. 29% of the patients required caudal epidural after 12 months after surgery for recurrence of their symptoms of neurogenic claudication. The cases were managed by a minimally invasive procedure using interspinous spacers. Materials and Methods: We retrospectively reviewed patients with lumbar degenerative disc diseases treated with IPD implantation and foraminotomy and/or discectomy between January 2016 and December 2019. Methods: She is 4'-9.5" and weighs 111 pounds. ... IPDs were approved for patient use at the beginning of the century (3) and introduced as a less invasive surgical alternative. Results Background: reported 2-year outcomes in 197 p, with neurogenic intermittent claudication treated with, demonstrating higher Zurich Claudication Questionnaire. Eur Spine J 2008; 17: 188-192. are used either as “stand-alone” implants or to augment, open decompression by preventing instability. Patients underwent serial follow-up evaluations. A clear understanding of the various implants and tools available and their associated complications is an essential component of sound spine surgical care. METHODS. The mean age of group ISU (66.2 +/- 6.7 years) was 6.2 years older than the mean age of group PLIF (60.4 +/- 8.1 years; p = 0.003 ). success rates than the scores for laminectomy patients. In both techniques, all parameters of disc changes and formainal diameters improved significantly with variable difference between both of them. Several devices have been developed within the last two decades and have been variously supported by investigations into their clinical and biomechanical efficacy. 3-day postoperative radiographs and CT examination, which allowed measurements of screw position relative to pedicle position according to Andrew classification, were performed routinely. However, the design for IPD to treat spinal stenosis does not fixate the spine while the design for spinal fusion is designed to fixate the spine. This study included n=374 patients; 40 excluded; 334 included (113=positive nerve root sedimentation sign (NRSS) (34%) and 221=negative NRSS (66%)). There were 17 major and 18 expanded MeSH terms extracted after bibliometric analysis. In our coflex Ò group no complication and revisions were observed, but the follow-up time was rather short with a mean of 9.2 months. Indications should emerge from thoughtful consideration of data from randomized controlled studies. Previous biomechanical studies demonstrated that fusing one level may significantly increase the intradiscal pressures at adjacent levels. Addolorata Hospital, Via Amba Aradam 9, Rome 00184, Italy. The combination of the percutaneous transforaminal endoscopic decompression (PTED) with an interspinous process distraction system (IPS) may offer additional benefit in the treatment of spinal stenosis in patients who have failed nonsurgical treatment. This study compared all available data on postoperative clinical and radiographic outcomes of topping-off technique and posterior lumbar interbody fusion (PLIF). In group A patients, there was a 4.48 reduction in the VAS score. Outcome measures were back and leg pain relief, COMI score improvement, patient satisfaction, complication, and revision rates. Axial rotation and lateral bending ranges of motion were not affected at the instrumented level. There were 27 fractures of the spinous process and 23 dura mater tears with cerebrospinal fluid leakage. The indications for the implantation of an IPD are spinal stenosis and neurogenic claudication, assuming that its function is the enlargement of the neural foramen and the decompression of the roots forming the cauda equina in the central part of the vertebral canal. Radiographic and clinical outcomes between the two groups were compared. UCLA shoulder score showed satisfactory results in 75% of patients. However, the device has only transient effect on the postoperative restoration of disc height and reduction of slip in spondylolisthesis. METHODS: 307 patients with spine diseases, who were treated in the First Affiliated Hospital of Guangxi Medical University from July 2008 to January 2014, were enrolled in this study. These devices would relieve the load on facet joints, restore the height of intervertebral foramen and maintain the stability of spine. and restabilizing the intersegmental motion segment. 0,5 Gy (Plazebodosis) unter Einschluss der Facettengelenke in funf Fraktionen bestrahlt. Conclusion: Refining pathological classification, optimizing surgical method and instrument property will be an expectable direction of spinal stenosis. Due to the long-term contact between spinous processes and Coflex devices, spinal process erosion and spinous process fractures often occurred . Methods: spinous process and 23 dura mater tears with CSF leakage. The flexion-extension range of motion was significantly reduced at the instrumented level. Fusion operations have traditionally been used to manage many disorders of the lumbar spine related to deformity, pain, or instability. High failure rate of the interspinous distraction device (X-STOP) for the treatment of lumbar spinal stenosis caused by degenerative spondylolisthesis. tween the base and the midportion of the spinous process, the spacer design and the osteopenic bone and metal in, patients treated with titanium or PEEK X-Stop and Lanx, using thin-cut CT sagittal reformatted images. The estimated blood loss was lower for the coflex cohort (106.2 versus 335.5 ml), and the average hospital length of stay was reduced by 1 day in the coflex group. Eur Spine J 2008;17(2):188–192. Seven lumbar spines (L2-L5) were tested in flexion-extension, lateral bending, and axial rotation. METHODS: A total of 203 patients with lumbar and sacral diseases, including lumbar fracture, lumbar spondylolysis and lumbar spinal stenosis, were recruited from Department of Spine & Osteopathy, the First Affiliated Hospital of Guangxi Medical University between July 2008 and November 2014. This study shows that the X STOP device increases the cross-sectional area of the dural sac and exit foramens without causing changes in posture. Park et al published one of the few studies with the Coflex implant [39]. Spacers placed between the lumbar, spinous processes have become relatively common mini, mally invasive surgical treatment alternatives for a variety, distractive force to the stenotic motion segment and have, the potential to relieve symptoms of degenerative disc dis, spacers have provided alternatives to arthrodesis in older, patients with degenerative lumbar disease. Studies have yet to investigate long-term radiologic changes in lumbar spinal stenosis patients treated with interspinous device (Coflex). The median compressive force acting on the Coflex implant was found to be 45.8 N. The maximum load change between flexion and extension was 140 N; the maximum overall load exceeded 239 N in extension. Three surgical models—two IPD models (TAU and SPIRE) and one PSF model—were developed. Eine psychosomatische Schmerzursache wurde ausgeschlossen. The complication rate was 7.8%. Furthermore, they are composed of a range of different materials including bone allograft, titanium, polyetheretherketone, and elastomeric compounds. Related complications occurred in 11 patients. 17: 188-92 Implant designs vary from static spacers to dynamized devices. Inclusion was based on high-grade stenosis, failure of conservative management and electromyography. Preoperative CT-based three-dimensional reconstruction navigation technique provides three-dimensional anatomical information, assists to develop pedicle screw insertion plan, enhances the accuracy and further improves the safety of pedicle screw insertion. Postoperative X-ray films and three-dimensional CT scan of lumbar bone were routinely examined in each patient. To prospectively assess the clinical outcome of patients with symptomatic lumbar spinal stenosis before and at periodic intervals after X Stop implantation and to compare the data with previous studies. BACKGROUND: Posterior pedicle screw fixation is an important method to treat various diseases of the spine and to stabilize the spine. Interspinous implants such as Coflex and X-Stop have been designed to treat lumbar neurogenic claudication secondary to spinal stenosis. Two 10 mm devices were implanted in the first patient and two 16 mm distractors in the second man. Veerhoof OJ, Bron JL, Wapstra FH, van Royen BJ. RESULTS AND CONCLUSION: A total of 1 088 screws were inserted in the lumbar and sacral bone. The charts of patient undergoing lumbar decompression with Interspinous Distraction, Fixation using InSpan device (INSPAN LLC) in an outpatient setting were reviewed with over a 5-year follow-up period. Dynamic interspinous process stabilization: review of com-plications associated with the X-¬Stop device. Preoperative, six-week, one- and two-year postoperative clinical outcomes were measured using Oswestry Disability Index (ODI) scores. Patients with lumbar decompression plus coflex(®) (SWISSspine registry) were compared with decompressed controls (Spine Tango registry). 7. In some severe cases, an additional fusion procedure is required to relieve the symptoms [17,18]. Payment trends Until recently, payers also existed within the two-bucket system, creating a reimbursement framework around simple decompression or fusion with nothing in between. Methods: This study details a 9 year single-centre experience with PIDs and examines the complementary use of spinous process augmentation (spinoplasty) to reduce failure rates. Verhoof et al reported in 2008 a high failure rate in IPD (X-stop), with an average slip on the radiographs of 19.6%, and a high surgical re-intervention rate (seven out of the 12) [35]. A three-dimensional finite element model analysis of the L1-S1 segments was performed to assess the biomechanical effects of the proposed IPD combined with an interbody cage. Conclusion: No significant decrease of the Disability Index after radiotherapy on the lumbar spine with 5 Gy could be demonstrated in the verum and placebo group. Results: According to the randomised distribution, 18 patients were treated with 5 Gy and 13 patients with 0.5 Gy. A logistic regression analysis was used to analyze risk factors for developing radiographic ASD. Thereafter, Coflex™ implant was inserted between two spinous processes and tightened wings with clamp. And the journal SPINE was the most authoritative with total 695 articles and average 12.73 citations. The indirect complications of implants are mainly the degeneration of the original surgical segment and the occurrence of ASD. MRI revealed an increased postoperative disc height with a mean difference of 0.5 ± 0.1 mm (p < 0.001).
