mittent claudication: two-year follow-up results. treatment. However, the two methods offer distinct biomechanical properties, which affect their respective effectiveness and surgical success. Level of evidence: A minimum of 3 years after IPD placement, information on long-term outcomes was obtained from additional follow-up or from patient medical and radiological records. The ultimate failure rate requiring additional surgery was 9.6%. Overdistraction, poor bone density, and poor patient selection may all be factors in the development of complications. As a conclusion we found lower total ABC scale has significantly association with falls in elderly. Coflex implants should be avoided in patients with osteoporosis, a narrow interspinous space and intervertebral coronal spondylolysis, or sagittal instability. In only 13 cases did, In this study the overall reoperation rate was 9, tional instrumented fusion with pedicle screws (T, When looking at the distribution of implant remov, with short procedures and hospitalizations. 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. The difference between topping-off technique and posterior lumbar interbody fusion (PLIF) in postoperative outcomes is still controversial. Heterotopic ossification was identified through lumbar anteroposterior and lateral view radiographs. BACKGROUND: Pedicle screw fixation techniques have been widely used in the treatment of lumbar and sacral disease, such as trauma, deformity, tumor and degeneration. The purpose of this paper is to provide a comprehensive overview on interspinous implants, their mechanisms of action, safety, cost, and effectiveness in the treatment of lumbar stenosis and degenerative disc diseases. 29% of the patients required caudal epidural after 12 months after surgery for recurrence of their symptoms of neurogenic claudication. 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. The Visual Analogue Scale and Oswestry Disability Index scores showed evident improvement in these patients. ... IPDs were approved for patient use at the beginning of the century (3) and introduced as a less invasive surgical alternative. Methods: Above findings suggested that computer navigation system-assisted spinal pedicle screw implantation provides real-time, multi-perspective, three-dimensional visualization of spinal anatomy, ensures the accuracy and safety of spinal pedicle screw implantation, and apparently reduces exposure time to radiation. Average follow up was 13 months. 502 screws were implanted in the thoracic vertebrae, including 492 grade-I screws (accuracy 98%). Materials and methods Eight L2-L5 specimens were positioned to 15 degrees of flexion and 15 degrees of extension using a positioning frame. Lendenwirbelsaulen der Patienten wurden randomisiert mit 5,0 Gy bzw. To read the full-text of this research, you can request a copy directly from the authors. High failure rate of the interspinous distraction device (X-Stop) for the treatment of lumbar spinal stenosis caused by degenerative spondylolisthesis. The ROM and disc stress at the surgical level in ILS were 1.27° and 0.36 MPa, respectively, and in ISS 1.51°and 0.55 MPa, respectively in extension. Bae et al. Schlussfolgerungen: Die niedrig dosierte Schmerzbestrahlung der Lendenwirbelsaule mit 5,0 Gy als Reservetherapie des chronischen Lumbalsyndromes zeigte sich in beiden Gruppen als nicht wirksam und wird von den Autoren nicht empfohlen. We do not recommend the X-Stop for the treatment of spinal stenosis complicating degenerative spondylolisthesis. In the short-term, lumbar decompression with coflex(®) compared with decompression alone in patients with LSS and pronounced LBP at baseline is a safe and effective treatment option that appears beneficial regarding clinical and functional outcomes. To determine the actual in vivo loading environment of an elastic interlaminar-interspinous implant (Coflex). Methods: All patients included in the analysis had a minimum of three years of follow-up. All surgery carries the risk of pain after recovery , which is why there are many different types of failed neck surgery, including: 122 surgical cases of lumbar decompression with interspinous fixation, spanning between the timeframe of September 2011 to October 2016. Conclusion In extension, the implant significantly increased the canal area by 18% (231-273 mm), the subarticular diameter by 50% (2.5-3.7 mm), the canal diameter by 10% (17.8-19.5 mm), the foraminal area by 25% (106-133 mm), and the foraminal width by 41% (3.4-4.8 mm). Thirty-seven studies were included from 2011 to 2016. spinal stenosis, discogenic low-back pain, facet syndrome. Nine patients underwent placement of the X-Stop device at the L4-5 interspinous space and 4 at both the L3-4 and L4-5 levels. degenerative disc disease and segmental instability recently extending their application. 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. The purpose of this review is to compare the first generation with the next-generation devices in terms of complications, device failure, reoperation rates, symptom relief, and outcome. Standard operation and strict follow-up observation can effectively avoid surgical technique-related complications. There was one revision converted to hemilaminectomy. ... Wapstra FH, et al. Measurement of the kinematics of the lumbar spine after insertion of an interspinous spacer in vitro. The reasons for revision, which always involved removal of the original implant, were acute worsening of low-back pain or lack of improvement (45 cases), recurrence of symptoms after an initial good outcome (42 … If the medical control of driving ability comes at the initiative of the user, the treating physician should firstly ensure the understanding of prescribed treatments that can cause hypoglycaemic episodes and other by informing diabetic person she must pass a medical examination of fitness to drive in a licensed physician. In addition, the TAU model increased IDP at the L2-L3 and L4-L5 levels by 118.0% and 78.5% in flexion, 92.6% and 65.5% in extension, 84.4% and 82.3% in lateral bending, and 125.8% and 218.8% in axial rotation, respectively. The disc height and foraminal area on radiographs also increased significantly, but with limited effects up to three months postoperatively. The use of interspinous process devices are less invasive surgical methods designed to manage mild to moderate lumbar spinal stenosis symptoms. Dynamic interspinous process stabilization: review of com-plications associated with the X-¬Stop device. RESULTS A lumbar laminectomy is a surgery that removes most of the bony arch of a vertebra to treat lower back pain. In the third patient the L4 SP fracture was detected when the patient presented because of recurrent back pain 18 months after the index surgery, but revision surgery was not consented. It is being done by a neurosurgeon, I've talked with a couple people who have had it done there and are pleased. 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. Several complications associated with the use of interspinous spacers have included device dislocation or malposition, spinous process fractures, infection, hematoma, erosion of the spinous process, and neurological sequelae (4, ... Several complications associated with the use of interspinous spacers have included device dislocation or malposition, spinous process fractures, infection, hematoma, erosion of the spinous process, and neurological sequelae (4,5). It is understood that the dimensions of the spinal canal and neural foramen increase in flexion and decrease in extension. 3. Only, were treated with IPD implantation alone or in combina, with IPD insertion in combination with interbody fusion, interbody fusion, and transforaminal lumbar interbody fu, and postoperative clinical assessments of the patien, 3 years after IPD placement, information on long, outcomes was obtained from additional follo, patient medical and radiological records. Due to the long-term contact between spinous processes and Coflex devices, spinal process erosion and spinous process fractures often occurred . Loads are typically approximated from cadaver tests or biomechanical calculations for the preclinical assessment of a device's safety and efficacy. The in vivo loading environment of load-bearing implants is generally largely unknown. Compared with the fusion group, the topping-off group showed preserved mobility at the Coflex(™) level (p = 0.000), which is associated with less blood loss (p = 0.000), shorter duration of surgery (p = 0.000) and lower incidence of ASD (Chi-square test, rate topping-off vs fusion = 13.2 vs 26.1 %, p = 0.039). Department of Neurosurgery, “Santo Spirito” Hospital; Regional Service of Neurosurgery, “Virgen de la, a lumbar disc surgery questionnaire that categorizes. Moreover, in most patients, fractures were associated with mild or no acute localized pain. Setting Five neurosurgical centers (including one academic and four secondary level care centers) in the Netherlands. The purpose of this review is to compare the first generation with the next-generation devices in terms of complications, device failure, reoperation rates, symptom relief, and outcome. Scoliosis and other spinal deformities are when there is an abnormality within the balance of the natural curves of the spine. It has been reported that the most common complications are screw loosening for HSDs and spinous process fracture for IPSs. Possible underlying theories and anatomic peculiarities which may predispose to this rare event are discussed. All subjects were asked questionnaire of ABC scale and history of falls. The primary outcomes measure was the Zurich Claudication Questionnaire, a patient-completed, validated instrument for NIC. Among 32 patients with follow-up times of 24-57 months, HO was detectable in 26 (81.2%). Lumbar spinal stenosis is treated with decompression directly such as laminectomies and indirectly with an interspinous device through distraction and extension block. IPD may offer an effective and less invasive alternative to classical microsurgical posterior decompression in selected patients with spinal stenosis and lumbar degenerative disk diseases. I had surgery for scoliosis when I was 16, 19~ years ago, they said my nerves would heal. It usually takes far longer for symptoms of numbness/tingling or wea… During the first three years, in 38 out of the 120 control cases, a posterior decompression and/or spinal fixation was performed because of unsatisfactory results of the conservative therapy. Preoperative, six-week, one- and two-year postoperative clinical outcomes were measured using Oswestry Disability Index (ODI) scores. Fifty implants (38 L4-5, 12 L3-4) were placed in 38 patients who completed follow-up and were included in final analysis. Design Randomized controlled trial. The Zurich Claudication Questionnaire (ZCQ), 36-Item Short Form Health Survey (SF-36), and radiographic assessment were used to determine outcomes. 2008; 17(2):188-192. One fracture displaced during follow-up evaluation. The implant fatigue strength is significantly higher than the measured median force, which explains the extremely rare observation of a Coflex fatigue failure. Eur Spine J 2008;17(2):188–192. It is a retrospective analysis of 12 patients with a mean age of 61 years. There were 27 fractures of the spinous process and 23 dura mater tears with CSF leakage. These devices continue to be evaluated in clinical trials. An appropriately sized implant was placed at L3-L4, and the pressure measurements were repeated. Massimiliano. Overall complication and failure rate of (7%, including 6% reoperations rate after device failure) tended to be relatively low compared to the complication rate of standard bony decompression. Results: 5606 scientific literatures were retrieved about spinal stenosis and the number maintained a roughly increasing trend from 108 in 2000 to 512 in 2018, only declining in 2011. Results: Coflex, a type of interspinous process implant, can provide intervertebral dynamic stability for surgical segments and effectively relieve lumbocrural pain. This is compared with 4.71° and 1.44 MPa, respectively in DA. physician. At six weeks, significant postoperative ODI correction was noted in both groups (p<0.001). To understand the kinematics of the instrumented and adjacent levels due to the insertion of this interspinous implant. High failure rate of the interspinous distraction device (X-Stop) for the treatment of lumbar spinal stenosis caused by degenerative spondylolisthesis. Go first to the Federation of State Medical Board's Physician Data Center website to check the doctor's basic information including, his or her board certifications, education, the list states where an active license is maintained, and any actions against the doctor. One 10 mm X-Stop at L3-L4 and one 12 mm at L4-L5, respectively, were implanted in the third patient. A literature review. Eur Spine J. The X Stop device was implanted at the stenotic segment, which was either at 1 or 2 levels in each patient. 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. ILS and ISS partly address the issues of segmental instability in DA and hypermobility and overload at the adjacent levels in DF. The ultimate failure rate requiring additional surgery was 9.6%. Narrowing caused by the pathological change of flavum ligamentum hypertrophy and posterior longitudinal ligament ossification attracts more attention in recent years. Park et al published one of the few studies with the Coflex implant [39]. Refining pathological classification, optimizing surgical method and instrument property will be an expectable direction of spinal stenosis. Interspinous spacer versus traditional decompressive surgery for lumbar spinal stenosis: a systematic review and meta-analysis. The purpose of this study was to determine the feasibility of using nerve root sedimentation sign to predict mid- to long-term clinical outcomes of patients treated with interspinous spacers for lumbar spinal stenosis. Overdistraction, poor bone density, and poor patient selection may all be factors in the development of complications. Archived. The design and surgical technique characteristics, mechanism of action, and clinical indications for interspinous implants are reviewed. 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. There were 27 fractures of the spinous process and 23 dura mater tears with CSF leakage. It distracts the posterior elements of adjacent vertebral bodies, unloading the intervertebral disc, limiting spinal extension, and improving central canal and neuroforaminal stenosis. 5 Gy or 0.5 Gy (placebo dose) were applied in five fractions to the lumbar spine including the facet joints. 5. The second operation group also improved postoperatively (each P < 0.05). surgically treated single lumbar level in 993 cases, summary of clinical outcomes at a minimum of 24 months of follow-up, according to the rating scale of Finneson and cooper, overview of complications and failures in patients who underwent ipd implantation at our hospitals, All figure content in this area was uploaded by Marcelo Galarza, es is a disabling disease common in the elderly, population, and several surgical and conserva, tive treatment options have been proposed for its man, gests that surgery for degenerative lumbar spine stenosis. Twenty-four out of 294 studies are included in the Meta-analysis. Both patient groups underwent follow-up evaluations at 6, 12, 24, and 36 months using the Zurich Claudication Questionnaire, the Visual Analog Scale score and spinal lumbar X-rays, CT scans and MR imaging. the aim of these devices is to unload spine, restoring foraminal height, and stabilize the spine by distracting the spinous processes. However, the device has only transient effect on the postoperative restoration of disc height and reduction of slip in spondylolisthesis. 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. At every follow-up visit, X STOP patients had significantly better outcomes in each domain of the Zurich Claudication Questionnaire. FITS WITH . Clinical outcomes were compared between positive and negative nerve root sedimentation sign groups; p ≤0.05 was considered significant. She is 4'-9.5" and weighs 111 pounds. Articles describing the following implants were included in this review: the Minns Device, the Interspinous "U," the Diam, the Wallis Implant, and the X STOP. 17: 188-92 The mean follow-up period was 13.6 months. 1:1 propensity score-based matching was performed. Bibliometric analysis was conducted by using online analysis software CiteSpace and Bibliographic Item Co-Occurrence Matrix Builder (BICOMB). 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 X-Stop interspinous device is designed for the treatment of patients with neurogenic intermittent claudication due to lumbar spinal stenosis. Axial rotation and lateral bending ranges of motion were not affected at the instrumented level. This cross registry study assessed potential benefits of the interlaminar coflex(®) device as an add-on to bony decompression alone. There were 52 elderly consisted of 26 (50%) men, 26 (50%) women, age range 61 – 90 years, mean 71.6 ± 6.5 years, and 17.3% of them have history of falls. The mean anterior disc height (ADH) and range of motion (ROM) were significantly decreased after surgery (15.161 mm vs. 13.788 mm and 9.63° vs. 7.13°). In, microinstability, after microdiscectomy we implanted an, Previously reported complications associa, accepted criteria, we noted a high rate of reintervention, ture. in 2 patients, and fracture of the spinous process in 1 case. There were no differences in complications between the two groups. Long-term, level I investigations are underway to explore the efficacy and usefulness of such procedures for the prevention of adjacent segment disease. Our results support the effectiveness of surgery in patients with stenosis. TLIF spinal fusion operation is a salvage procedure. No drainage was neces, after surgery. A: To be a candidate for treatment with decompression and the coflex ® device, you must be skeletally mature. For statistical analysis, the patients were grouped by indication and procedure, which resulted in 12 different groups. Thus the Coflex offers nonrigid fixation and can return a partially destabilized specimen back to the intact condition in terms of motion in flexion/extension and axial rotation. The present study aims to evaluate the cost-effectiveness of Dynamic Interspinous Spacer (Coflex®) and Static Spacer (X-STOP ®) compared to Laminectomy (LAMI) in patients with lumbar spinal stenosis. In both groups, clinical measures improved significantly than preoperative values (p < 0.001). © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research , All Rights Reserved. Spinal stenosis may occur throughout the spine but is typically more common in the lumbar spine however more dangerous in the cervical spine due to the proximity to the spinal cord. (24) in their studies including 589 patients evaluating the clinical outcome following application of Coflex implants have demonstrated a significant reduction in patients back pain as regards (VAS) in the follow-up period which was. Results: Five fractures were associated with mild to moderate lumbar back pain and six fractures were asymptomatic. Overall, patients with fractures tended toward poorer outcomes by Zurich Claudication Questionnaire (ZCQ) (28.5% vs. 34.8% improvement in symptom severity, P = 0.496; 21.4% vs. 30.7% improvement in physical function, P = 0.199) and tended toward lower satisfaction rates (50% vs. 73.7%, P = 0.24) at one year compared to patients without fracture. ILS achieves greater segmental stability and results in a lower disc stress, compared to ISS. Postoperative ROM and ROM ratio were higher in the erosion group (5.95° vs. 8.47° and 0.659 vs. 0.938). Topping-off can effectively prevent the adjacent segment disease from progressing after lumbar internal fixation, which is be more effective in proximal segments. In conclusion, the X-Stop interspinous distraction device showed an extremely high failure rate, defined as surgical re-intervention, after short term follow-up in patients with spinal stenosis caused by degenerative spondylolisthesis. The following anatomic variants were demonstrated: markedly decreased interspinous distance (kissing spine-like), with concomitant facet joint hypertrophy, a posterior V-shaped interspinous area, limited accessibility of the space between the base and the tip of the SP because of facet joint hypertrophy and variations in the shape of the inferior surface of the cranial SP. The indirect complications of implants are mainly the degeneration of the original surgical segment and the occurrence of ASD. The ultimate failure rate requiring additional spinal surgery was 85% (11 of 13 patients). spinous process and 23 dura mater tears with CSF leakage. The most important result is that the motion segment after destabilization and insertion of the Coflex device does not allow significantly more or less motion than the intact specimen in either flexion/extension or axial rotation. 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.
