The processes of degeneration are complex and involve deterioration of both the anterior and posterior spinal column. Grade B high signal intensity on T1- and T2-weighted images. In this prospective consecutive data collection, 118 positional MRI scans of the lumbar spine were collected from July to December 2007. McMINN. The interspinous ligament tears at the L4-L5 and L5-S1 level would not have been diagnosed without the MRI. The recovery period for a neck sprain injury can last from several weeks to several months. Our classification is based on the signal intensity of the interspinous ligament and specific characteristic changes within the ligaments using mid-sagittal T1- and T2-weighted MRI. Rheumatol Int 2:87–96. Subtle avulsion of the supraspinous ligament at T1. This study demonstrated the excellent diagnostic ability of ultrasound to detect the status of the supraspinous and interspinous ligaments, especially in patients who undergo surgery. First, we used 0.6 T MR imaging, which is not the dominate system in use today, and may provide low-resolution images. There are two primary ligament systems in the spine, the intrasegmental and intersegmental systems: 1. The ligamentum flavum, which is made up almost entirely of elastin fibers. Introduction . MRI characteristics of interspinous ligament degeneration have been considered in previous studies [ 9, 10 ]. Figure 39-2 The Intrasegmental System holds individual vertebrae together and includes the ligamentum flavum, interspinous, and the intertransverse ligaments. Many classifications of degenerative change of the lumbar intervertebral disk and facet joint osteoarthritis have been proposed. The interspinous space is prepared all the way to the ligamentum flavum using blunt dissection, being careful to only remove the necessary interspinous ligament and potential bony overgrowth to allow room for insertion of the DIAM™ System implant. Grade D low or iso-signal intensity on T1- and T2-weighted images with marked narrowing of the interspinous interval. The mean age was 48.8 years (range 23–85 years) and mean body weight was 183.93 (range 115–240 lb). https://doi.org/10.1007/s00586-010-1327-8, DOI: https://doi.org/10.1007/s00586-010-1327-8, Over 10 million scientific documents at your fingertips, Not logged in The overall grades of interspinous degeneration assessed by each reader are shown in Table 2. Since MRI provides excellent soft tissue evaluation and multiplanar capabilities, the assessment of midline structures, such as spinous processes, and supraspinous, and interspinous ligaments, can be clearly viewed using mid-sagittal imaging [9]. Pain Physician 11:549–554, PubMed  Of the interspinous ligaments considered normal, 80% were classified as Type 1A. Spine 5:133–142, Kirkaldy-Willis WH, Wedge JH, Yong-Hing K, Reilly J (1978) Pathology and pathogenesis of lumbar spondylosis and stenosis. The length of recovery time is due to… The interspinous ligament may undergo degeneration with narrowing of the distance between spinous processes, ... are reported in less than 10% of all patients who undergo lumbar MRI. This indicates that this classification may require a higher resolution of imaging or objective measures of signal intensity. An in vitro biomechanical study 1981 Volvo Award in Biomechanics. With active inflammatory changes or edema on imaging, localized injections of steroid into the interspinous ligaments can be proposed . Article  There are a number of limitations for this type of study. Interobserver reliability was lower; however, the values remained within substantial to excellent agreement. MRI characteristics of interspinous ligament degeneration have been considered in previous studies [9, 10]. A radioanatomic analysis of the nondiscal structures of the spinal column and perispinal soft tissues. Recent studies have shown that significant pain relief can be achieved after interspinous ligament injections, supporting its possible role in low back pain [17, 18]. This should be done only as needed using a curved blade, tissue resectors, a curved The prevalence of this condition has been described in previous MRI studies as 8.2%, which is comparable to the percentage of grade C in our study [3]. Marked fatty replacement with a high signal intensity on both T1- and T2-weighted images (staged as grade B in our study) might represent fatty degeneration within the ligament. Degenerative change of the lumbar spine is a major source of low back pain and disability in older age people [1]. Progressive loss of interspinous space, hyperplasia, sclerosis, and marrow changes within spinous processes were also considered to reflect severe ligament degeneration (staged as grade D in our study) [9]. They meet the ligamenta flava in front and blend with the supraspinous ligament … doi:S1529943002001420[pii], Article  Instructions explaining the classification system and a set of sample images were given to all readers during the review (Fig. Complete interobserver agreement was achieved in a range from 167 (83.5%) to 178 (89%) of all 200 levels. Spine J 2:95–100. The supraspinous ligament runs along the tips of adjacent spinous processes and is particularly thick in the cervicothoracic region.Above the level C7 spinous process the ligament no longer directly attaches to the spinous process but rather continues as the nuchal ligament up to its attachment to the external occipital protuberance 1,2. Although ultrasound examination appears to be less sensitive than MRI in predicting ligament … The increased interspinous distance ratio (ISDR) at the fracture site in plain X-ray is useful as an indicator of injury of the posterior ligament complex in thoracolumbar fractures. The L3-4 interspinous ligament is thickened (black arrow). The results of intra- and interobserver reliability are summarized in Table 3. Only meticulous history and diagnostic block help in making a proper diagnosis. MR classification for interspinous ligament degeneration was developed on the basis of a comprehensive literature review of previously published studies examining anatomical, radiological, and histological aspects [3, 4, 9, 10, 12]. The overall intraobserver and interobserver agreement and disagreement are shown in Table 4. No disclosure of funding received for this work. A standardized nomenclature is required for the comparison of data from different investigations [11]. The signal change in grade C mimics that considered to be interspinous bursitis. This proposed MRI classification of interspinous ligament degeneration was simple, reliable, and reproducible. 16 Interspinous signal change is more likely at levels of anterolisthesis. Cells Tissues Organs 183:1–11. MRI classification of interspinous ligament degeneration of the lumbar spine: intraobserver and interobserver reliability and the frequency of disagreement, https://creativecommons.org/licenses/by-nc/2.0, https://doi.org/10.1007/s00586-010-1327-8. The cascade of interspinous ligament degeneration has not been defined well. Low signal intensity on T1- and high signal intensity on T2-weighted images (staged as grade C in our study), were found to correlate with a dominant extensive proliferation of cells and vascular invasion. The interspinous ligaments join the spinous processes along their adjacent borders. Ouch, it hurts.....imaging demonstrates that it has been like this in MRI's going back to January 2006 and the most recent is January 2016. We proposed an MRI classification system for interspinous ligament degeneration and conducted a comprehensive reliability and reproducibility assessment. (b) Corresponding MRI (T 2 weighted with fat suppression) with high signal intensity oedema/fluid in the interspinous spaces (arrows). Despite the growing clinical importance of interspinous ligament degeneration in low back pain patients, formal reliability studies for the magnetic resonance imaging (MRI) evaluation of interspinous ligaments have not been performed. The frequency of disagreement was calculated for each grade. We classified the degeneration into four grades according to the signal intensities and characteristics of structural changes of interspinous ligament and surrounding tissues using mid-sagittal images of T1- and T2-weighted MR images (Table 1). We proposed an MRI classification system for interspinous ligament degeneration and conducted a comprehensive reliability and reproducibility assessment.

Google Scholar, Panjabi MM, Goel VK, Takata K (1982) Physiologic strains in the lumbar spinal ligaments. Fifty patients who had low back pain with or without leg discomfort (26 males and 24 females) with a mean age of 48.8 years (range 23–85 years) were studied. MRI of the lumbar spine can clearly depict Baastrup's disease, interspinous bursal fluid, and an associated posterocentral epidural cyst. As expected, a difference of 1 grade occurred more often than a difference of 2 grades. Alar ligaments: stress or trauma can stretch the weaker alar ligaments, causing an increase in range of motion of approximately 30%. All statistical analyses were performed using SPSS (version15, SPSS, Chicago, IL, USA). MRI characteristics of interspinous ligament degeneration have been considered in previous studies [9, 10].

MRI features of lumbar interspinous bursitis (Baastrup\'s disease) Section. Its use as a standardized nomenclature in clinical and radiographic research may be recommended. In contrast to CT, an MRI may notice interspinous bursal fluid and a postero-central epidural cyst(s) at the opposing spinous processes . The MRI scan marked A (left) was taken at baseline and shows lots of bone marrow inflammation or osteitis at the attachment site of the annulus fibrosus (yellow arrows). Check for errors and try again. As expected, disagreement of 3 grades (between grades A and D) was less frequent than the difference between 1 or 2 grades in both intraobservation and interobservation. In the groups with a disagreement of 1 grade, a difference between grades A and B was much more frequent than between grades B and C, and between grades C and D in both intraobservation and interobservation, and represented the highest rates of disagreement in the study. The interspinous region is an often overlooked cause of back pain. J Rheumatol 14:788–797, Cohen J (1960) A coefficient of agreement for nominal scales. Regarding the frequency of disagreement in the groups of two grade difference, the percentage of difference between grades A and C was slightly higher than between grades B and D in both intraobservation and interobservation. All readers were instructed to precisely follow the classification algorithm. Although the clinical importance of the interspinous ligaments has been revealed, reproducibil-ity studies of MRI evaluation of interspinous ligaments have not been performed. All patients were referred for lumbar MRI in the evaluation of symptoms of back and/or leg pain. Complete agreement within readers ranged from 181 (90.5%) to 188 (94%) for the 200 levels.

Excessive flexion, strains the ligament near its bony attachment resulting in bony spur formation with repeated extension causing compression of adjacent inflamed structures and impeding healing. Since this is a retrospective analysis, we could not confirm the presence of ligamentous pain with diagnostic injections.

Example of each grade of interspinous ligament degeneration (arrowhead). d The reliability of this system was evaluated by examining both intra- and interobserver reproducibility. 1. However, based on prior well-correlated radio-pathologic studies, it is likely that our MRI classification represented the interspinous ligament degeneration cascade. This may be explained by a disproportionately high percentage of grades A and B, resulting in a more frequent misinterpretation between these grades. Also, disagreement of 2 grades was lower than disagreement of 1 grade. In conclusion, we have described a classification system for interspinous ligament degeneration using mid-sagittal T1- and T2-weighted MRI. MRI of the lumbar spine was performed using a 0.6 Tesla MRI scanner (Upright Multi-Position MRI; Fonar Corp, Melville, New York). The interpretation of reliability coefficients suggested by Landis and Koch [14] was performed: kappa 0–0.2 indicated slight agreement, 0.21–0.4 fair agreement, 0.41–0.6 moderate agreement, 0.61–0.8 substantial agreement, and 0.81–1.0 excellent agreement. Intraobserver and interobserver reliability were assessed by kappa statistics.

CHURCHILL LIVINGSTONE. Interspinous bursography is not really necessary for preoperative evaluation of spinal stenosis for these patients. This correlates with grade A interspinous ligament degeneration in our study. Loading images... Sagittal T2 There is subtle elevation of the supraspinous ligament at its T1 spinous process attachment, with associated focal marrow edema within the tip of the T1 spinous process as well as localized subligamentous edema, which is appreciated on the T2 fat saturated sequence. The condition is thought to occur due to repeated strain on the interspinous ligaments [1, 3]. Posterior spinal ligament pathology is becoming increasingly recognized as a significant cause of low back pain. We believe that this classification is easy to apply and comprehend and may be used as a standardized nomenclature for clinical and radiographic investigations of interspinous ligament pathology. Each reader analyzed the images on separate occasions after the selected images were randomly reordered, with a minimum interval of 1 week. Recently, degeneration of the posterior spinal ligament has been considered to be one of the causes of low back pain [3, 4] prompting numerous studies to further evaluate the role of the interspinous ligament.

Introduction:Interspinous ligament is an uncommon but potential pain generator in the spinal column that can give rise to chronic low backache. The distribution of MRI characteristics of interspinous ligament degeneration has not been documented well. Interestingly, disagreement was less frequent when the difference involved grade D (grades A and D, B and D, and C and D). Additional clinical studies may be conducted using our proposed classification system. Although research regarding interspinous ligament degeneration has been increasing, few studies have focused on the MRI characteristics of the interspinous ligament [3, 7, 10]. The lumbar spine MR images were assessed independently by three spine surgeons with 3, 7, and 9 years of experience with lumbar spine MRI. Grade A was seen in 85–101 levels (42.5–50.5%), grade B in 76–92 (38–46%), grade C in 6–11 (3–5.5%), and grade D in 14–18 (7–9%), depending on the reader. Conclusion: MRI was found to be highly sensitive in detecting injuries to the spinal cord and the posterior longitudinal ligament and … Google Scholar, Mitra R, Ghazi U, Kirpalani D, Cheng I (2007) Interspinous ligament steroid injections for the management of Baastrup’s disease: a case report.

Additionally, the reliability of the assessment tool has a critical influence on the validity of acquired data. Interspinous Ligament Damage (Neck and Back Sprain) Damage to interspinous ligaments, most commonly caused by whiplash, negatively impacts the stability of the spine as well as the body’s ability to move properly. Four lumbar spinal levels (L2–3, L3–4, L4–5, L5–S1) were used and a total of 200 interspinous ligament levels were evaluated on T1- and T2-weighted mid-sagittal images. They extend from the root to the apex of each spinous process. AJR Am J Roentgenol 145:1025–1030, CAS  The classification for lumbar interspinous ligament degeneration was developed on the basis of the literature using mid-sagittal T1- and T2-weighted images. These studies include an investigation of its mechanical role in spinal stability using biomechanical testing [5, 6], and anatomical, biochemical, and pathological changes in the degenerative aging spine [6, 7]. Nonetheless, we found sufficient agreement with these images. The role of the interspinous ligament is to limit flexion (bending forwards) through restricting separation of the spinous processes of the vertebral column. Most of these differences were between grades A and B. This article is distributed under the terms of the Creative Commons Attribution Noncommercial License which permits any noncommercial use, distribution, and reproduction in any medium, provided the original author(s) and source are credited. Massive fibrosis with chondrometaplasia was predominately observed as low-signal intensity on both T1- and T2-weighted images with hypertrophy of the spinous process. These ligaments originate partly from the ligamenta flava, partly from the corresponding vertebral laminae, and partly from the caudal aspect of the spinous process. We examined the mid-sagittal T1-weighted spin echo images (repetitive time 671 ms, echo time 17 ms, thickness 4.0 mm, field of view 30 cm, matrix 256 × 224, NEX 2) and mid-sagittal T2-weighted fast spin echo images (repetition time 3,000 ms, echo time 140 ms, thickness 4.0 mm, field of view 30 cm, matrix 256 × 224, NEX 2) with a quad channel planar coil. This signal intensity was controversially considered to be “interspinous bursitis” (Baastrup’s disease) with a pathological correlation of increased vascularity, eburnation, and formation of bursae [3, 12, 19]. Although the histological examination revealed various degenerative changes within the interspinous ligament, the dominant characteristics were identified in MR findings. Interspinous ligament sprain is difficult to diagnose with radiologic imaging, such as X-ray, and magnetic resonance imaging. A second possible cause for this occurrence is the increased difficulty of distinguishing bright and intermediate signal intensities, which are characteristic of grade B and grade A, respectively. Google Scholar, Landis JR, Koch GG (1977) The measurement of observer agreement for categorical data. For this report, we performed bursography to document the direct communication between the bursa and the epidural cyst. MRI is a powerful diagnostic tool that can provide important clinical information regarding the … The mean age and disc degeneration grade of the patients with the Type 1B ligaments was significantly higher. a also found that two-thirds of their study population presented with an interspinous ligament signal intensity similar to that of grades A and B in our study. A difference of 1, 2, and 3 grades occurred in 8.1, 3.0, and 1.1% of readings, respectively. Hierarchia anatomiczna. (c) Corresponding three-dimensional (3D) CT demonstrating narrowing of the interspinous spaces (arrows). The ISLs are well vascularized and contain sensory nerves, particularly on their dorsal and lateral surfaces. Jeffrey C. Wang. PubMed  In this study we focused on the reliability and reproducibility of this classification system and also the frequency of disagreement at each different grade. The percentage of each grade assigned by each reviewer was determined. The frequency of disagreement was relatively less when the difference involved grade D (grade A and D, B and D, C and D). Overall complete agreement was obtained in 87.8% of all interspinous ligament levels.

Three spine surgeons independently graded a total of 200 interspinous ligament levels. Using our proposed classification, we found intraobserver reliability to be excellent in all observers. Its use as a standardized nomenclature in clinical and radiographic research may be recommended. When the patient had a flare of disease and was rescanned on image marked B (right) the inflammatory lesions on the original scan had resolved. 2. There was no obvious difference in kappa values between the three readers who are all spine surgeons with different levels of clinical experience. 6. b Kirkaldy-Willis [2] categorized the degenerative cascade into three phases: dysfunction, instability, and restabilization. Prior studies have evaluated MRI findings in asymptomatic control subjects and non-pathologic cadaveric lumbar spines [7, 10], revealing low-signal intensity on both T1- and T2-weighted images to correspond with the earliest stages of degeneration. doi:10.1159/000094901, Tehranzadeh J, Andrews C, Wong E (2000) Lumbar spine imaging.

Although the clinical importance of the interspinous ligaments has been revealed, reproducibility studies of MRI evaluation of interspinous ligaments have not been performed. They are composed of relatively weak fibrous tissue that fuses with the stronger, supraspinous ligaments. In our study, most interspinous ligament degeneration was grade A or B. Fujiwara et al. Low back pain is extremely common, with a lifetime individual prevalence between 49% and 90%1,2,3,4,5, and it is a top 5 chief complaint in emergency departments in the United States and Canada.6,7Back pain is often multifactorial, most commonly attributed to discogenic and facetogenic abnormalities. (d) Sagittal MRI Clinical-radiographic relationship investigations need a standardized and reproducible imaging classification in order to compare outcomes.

Second, we cannot definitively define the clinical correlation of this classification system. However coming to the ligamentum flavum and interspinous ligaments, the sensitivity of the MRI dropped to 62.5% and 63.6% respectively. There were 14 Type 1A, 30 Type 1B, 19 Type 2, 16 Type 3, and 20 Type 4 ligaments. They are composed of relatively weak fibrous tissue that fuses with the stronger, supraspinous ligaments.
