This entity is sometimes difficult to diagnose particularly during the onset of the disease. The cardinal symptoms are:) "inflammatory" back pain) typical arthritis pain (pain at night and stiffness in the morning)) progressive spinal stiffness) progessive hyperkyphosis (inability to look straight ahead) Inflammatory back pain is a hallmark the diagnosis is often delayed 1062 Section Tumors and Inflammation Table 1. The criteria [80] for inflammatory back pain in younger patients (< 50 years) are shown in Table 1. Several sets of combined parameters proved to be well balanced between sensitivity and specificity. If at least two of the aforementioned four parameters were fulfilled (positive likelihood ratio 3. If at least three of the four parameters were fulfilled, the positive likelihood ratio increased to 12. The frequency, duration and intensity of these concomitant disorders varies individually. Frequent physical findings are:) pain provocation of sacroiliac joints (positive Mennell test)) decreased spinal mobility (Schober and Ott test)) anterior sagittal imbalance (plumbline falling in front of the hip joint)) coronal spinal imbalance (less frequently)) reduced chest expansion during inspiration and expiration after a chronic progression) loss of body height A neurological examination of the upper and lower extremities is mandatory to diagnose neural compression. In the presence of severe back pain, it is mandatory to rule out a spinal instability or an occult fracture [34, 42] in order to prevent neurological deterioration due to epidural bleeding or secondary fracture displacement [77, 78]. Furthermore, an increased force effect for the small vertebral joints can be observed with the risk of atlanto-occipital subluxation or even a vertebral dislocation. Pain, stiffness and reduced range of motion in peripheral joints can occur at any stage of the disease. A thorough examination of the large diarthrodial joints and the search for enthesopathies is compulsory in addition to the mandatory clinical examination of the spine [37, 38]. A positive family history and reports of typical arthritis symptoms such as pain at night and stiffness in the morning can be helpful. Standard radiography remains the mainstay of diagnostic imaging 1064 Section Tumors and Inflammation b a c Figure 1. Syndesmophytes exhibit a slow growth from the cervical to the lumbar spine [17] leading to a kyphotic deformation of the entire spine and often resulting in a progressive sagittal imbalance. The fractures are atypical compared to fractures of the undiseased bone [57] and frequently involve all three spinal columns [103]. Standard examinations searching for inflammatory alterations are done in the coronal and sagittal plane using fluid sensitive sequences with fat signal suppression. Magnetic resonance imaging can demonstrate injuries to the ligaments or sequelae of spinal trauma. Bone Scan Bone scan remains a screening tool for inflammatory processes Bone scans still play a role as a supraregional screening modality for inflammatory reactions. The specificity of a sacroiliac joint scintigraphy is reduced due to a high bone turnover metabolism [20]. A scintigraphy can also be useful in the search for inflammatory lesions or aseptic discitis. The location of the spine pathology is important for differentiation between a fracture, metastasis, inflammatory lesions or discitis. However, in the early stages a sacroiliitis can be absent in 70 ­ 90 % of all cases [81]. Other typical clinical symptoms and signs are inflammatory back pain, progressive spinal stiffness and Ankylosing Spondylitis Chapter 38 1067 reduced chest expansion. At the level of the spinal column inflammatory lesions appear mainly at the thoracic level [8, 17, 105]. An active stage is defined as persisting clinical symptoms for a minimum of 6 months. Diagnosis is still difficult and based on the presence of multiple findings Non-operative Treatment Ankylosing spondylitis is a chronic, systemic disease which cannot be cured. General objectives of treatment) control of inflammatory processes) prevention of disease progression) preservation of spinal mobility) pain relief) preservation of spinal balance) improvement of quality of life Natural History Ankylosing spondylitis is a chronic inflammatory disorder with varying disease progressions and accordingly mild to severe clinical symptom intensity. However, in less than 1 % of all patients a long term remission has been described [52]. Progression of ankylosing spondylitis is usually linear [22] and affects either isolated structures or a combination of them [106]:) sacroiliac joints) axial skeleton) peripheral joints) extra-articular structures In spondylarthopathies in general, several prognostic factors have been identified which correlate with disease severity [1]:) hip arthritis) high erythrocyte sedimentation rate (> 30 mm/h)) poor efficacy of non-steroidal anti-inflammatory drugs) limitation of lumbar spine) sausage-like finger or toe) onset 16 years Ankylosing spondylitis is a chronic inflammatory disorder with a varying level of disease 1068 Section Hip involvement is a strong predictor of poor outcome Tumors and Inflammation If none of these factors is present at entry, a mild outcome can be predicted with a high sensitivity (92.

A noncontained disc derangement denotes disc material escaping the confines of the annulus fibers. Axial schematic image of a paracentral disc herniation displacing an S1 nerve root. Axial image of a paracentral disc herniation (green arrow) that contacts and displaces the left S1 nerve root. Anterior disc herniations do not compromise the spinal cord, thecal sac, or nerve roots, but may be a source of pain and indicative of biomechanical failure. Even a small herniation in the foraminal canal can cause significant nerve impingement. Far lateral herniations may contact and affect the exiting nerve root after it leaves the intervertebral foramen. The image on the right outlines the circumference of this far lateral herniation which is visualized in both images. These are the volume descriptors for the amount of disc material herniated into the central canal as observed on the axial image at the slice of most severe compromise. A canal compromised less than one-third is a mild herniation (figure 5:52), between one-third and two-thirds is considered a moderate herniation (figure 5:53), and over two-thirds is a severe herniation (figure 5: 54). Annular tears may occur from trauma or over time as part of a degenerative process. Some experts prefer the term annular fissure since it is less implicative of trauma. There are three categorizations of annular tears: radial tears, transverse tears, and concentric tears. Annular tears may be clinically significant or may be asymptomatic coincidental findings. Radial Tears Radial tears begin centrally and progress outward in a radial direction. Radial tears may precede the migration of the nucleus, resulting in a disc herniation. Radial tears of the disc radiate out in a radial direction from the center of the disc. Radial Tears these two T2 sagittal images demonstrate radial tears of the annulus of the disc between L5 and the sacrum. Transverse tears are horizontal lesions that may involve the disc tearing away from the endplate. Transverse tears appear to have a causal effect in degenerative disc disease and the formation of osteophytic spurring. They are typically small and limited to the joining of the annular attachments to the apophyseal ring­the rim of the vertebra, hence the term rim lesion. The two images above show a transverse annular tear from the superior endplate at the posterior margin of the sacrum. Below is an image from a different patient with a small tearing of the annulus fibers from the superior apophyseal ring of the sacrum. Annular tears are well demonstrated in T2 images and appear as high-intensity zones, thus appearing white in T2 weighted images. Incidentally, it is the outer third of the annular fibers that are the most richly innervated and vulnerable to nociception. They are characterized by high intensity zones (white appearance) on T2 weighted images. The T2W images above are from the same patient and show a transverse concentric tear involving the posterior portion of the L5-S1 disc. As you view this pictorial essay take a moment to consider the components of each disc herniation: the vertebral level, the anatomical zone, and the type of derangement (tear, extrusion, protrusion, bulge, intravertebral herniation, and so forth). In addition to identifying the nomenclature and classification of the disc lesions, take time to familiarize yourself with the other structures in each image. Moreover, consider the impact of disc derangement on facets, muscles, ligaments, endplates, vertebral bodies, the canal space, epidural venous plexus, sacroiliac joints, and other anatomical structures.

Many journals published for the chiropractic profession, including the Journal of Manipulative and Physiological Therapeutics, Chiropractic Technique, Chiropractic Research Journal, Journal of Vertebral Subluxation Research and Chiropractic Sports Medicine, provide articles on the appropriateness of various examination procedures, but there is little information in history taking procedures. The articles range from describing the measurement of lumbar range of motion to objectively measuring the strength of the biceps muscle. These considerations increase our need for objective information gained from well-designed research projects. The history-taking procedure has been considered the most clinically sophisticated and complex task used by health care providers. These are then confirmed or altered following the judicious selection of additional tests - and it can be noted in the literature that this process does indeed occur. One study determined that a sample group of practitioners determined their first hypothesis regarding the diagnosis of a random sample of patients an average of 28 seconds after hearing the chief complaint. Much of the information that will lead a clinician to a management plan, then, is gained very early in the doctor/patient interaction. He found that the percentage of diagnostic completion was as high as 73% after the history and physical examination alone. This may result in unnecessary testing procedures in order to determine that the hypothesis made during the history is incorrect, or may result in an appropriate confirmatory test not being used and the patient being treated inappropriately. Further the meaning of words used by the patient may not be the same as that of the practitioner. All of the above are further complicated when the first language of the clinician is not the same as that of the patient. It is perhaps for these reasons that the accuracy of patient histories has been questioned, and significant variability noted. Facilitation is the encouragement given by the clinician to allow patients to tell their own stories in their own words, and collaboration is the degree to which patients are considered partners in the process by which they receive care. The literature is sorely lacking with respect to controlled randomized clinical trials directed at measuring reliability and validity of specific history taking procedures. A thorough review of practitioner reliability studies performed by Koran did not include any studies relating to history taking. Earlier studies, in which practitioners interviewed different samples of patients drawn from one population, found considerable disagreement in symptom prevalence rates. While vertebral subluxations and other malpositioned articulations and structures may be asymptomatic it is known that they commonly have peripheral physiological effects. Therefore, the examination, although heavily concentrated on the spine may include procedures remote from the spine including,but not limited to other physical examination procedures, clinical laboratory and imaging procedures. Utilization of this procedure should help the examiner to detect abnormalities and therefore develop a more thorough assessment of spinal function. Chiropractic colleges place palpation techniques high on their curricular agendas. Standardized training and protocol for palpation is necessary and should be promoted by the colleges to help improve inter-examiner reliability. As a result a social interactive component must be recognized and taken into account in order to make appropriate choices during the physical examination and any additional testing procedures. One is the exhaustive approach, with the completion of a comprehensive series of all tests that may significantly contribute to determining the diagnosis. Another style, the one generally used to obtain the history and perform the physical examination, is the hypothetic -deductive approach. The practitioner then attempts to gather historical and physical information to either support or refute the potential working hypotheses. The physical examination, while apparently objective, is no less riddled with social issues than the history. It has been noted that the assessment of the observer, instructions given to the patient, and sincerity of response are important. When, for example, an almost 30% difference is found in the sensitivity of a test such as sensory loss used to help diagnose a herniated lumbar nucleus pulposis for two different samples, it is difficult to know if the difference lies in the test itself or in the doctor-patient relationship. The more motivated patients are, the more likely they are to fairly represent their maximum capacity on a physical performance test.

The energy expenditure when running on level ground is on a magnitude of 1 kcal per kg of body weight and kilometre, while the corresponding value for walking is 20­25 per cent lower. Accordingly, one hour of walking corresponds to 1/10 of the energy expenditure per day of a standard man (2,800 kcal per day) or woman (2,100 kcal per day). It being difficult and nearly impossible to predict on an individual level how more physical activity will affect body weight and body composition is illustrated by the fact that three glasses (of 2dl each) of a soft drink that may be consumed in connection with training also corresponds to 10 per cent of the daily energy needs. It has been said that the increase in the average weight of 20­40 year-olds in the U. This corresponds to just 15­20 minutes of walking or one glass of a soft drink (62). Low energy levels and low levels of insulin in plasma, which is often observed after an exercise session, stimulates the appetite through neuropeptide Y-releasing neurons in the central nervous system. At the population level, knowledge about how regular physical activity affects body composition is more certain, and several major studies with observation times of approximately 3­4 months show that various exercise programmes can be expected to provide a decrease in fat weight of an average of 0. As a rule, the decrease in fat weight is always larger than the decrease in body weight, and body weight often does not change at all due to increased muscle mass (63). Although a tendency of larger decreases are seen in men, it cannot be said for certain that any gender difference exists. The increased adrenaline effect on the release of fatty acids among trained individ- 1. The number of receptors for adrenaline on the surface of the fat cells is probably not affected by exercise, however. To some extent, the increased fat degradation activity in adipose tissue from trained individuals can be seen as a compensation for a lower overall adipose tissue mass in a trained individual (64). In the past decade, it has been discovered that adipose tissue is significantly more metabolically active that was previously known. Today, it is known that several potent peptides are released from adipose tissue and have important effects on other organs in the body. Two such peptides are leptin, which has an anorectic effect on the energy balance and also affects sugar metabolism, and adiponectin, which stimulates fat burning. It has not been established how physical activity and exercise training affect these factors, but the decreased fat mass seen with exercise training can be expected to decrease the significance of these factors (88). Leptin has been examined in several studies, but there does not appear to be any unambiguous effect of exertion or exercise training on leptin levels. Nervous system Much of the knowledge that applies to the effects of acute exertion and exercise training on the nervous system is gathered from studies of animals, but growing numbers of human studies of cognition and learning are being published. Acute exertion During exertion, the brain has a total metabolism and total blood flow that do not significantly differ from that at bodily rest. However, during exertion, the activity, metabolism and blood flow in the areas that take care of motor activity increase measurably. Besides glucose, the brain uses lactic acid as an energy substrate under intense exertion. The release of neurotransmitters (signal substances) such as dopamine, serotonin and glutamate in various parts of the brain are also affected during physical exertion. Effects of exercise training Regular physical activity affects several different functions in the human nervous system (89). Functions connected more directly to physical activity improve, such as coordination, 30 physical activity in the prevention and treatment of disease balance and reaction ability. This increases the functional ability, which can contribute to the increased well-being which is tied to regular physical activity. Moreover, cognitive ability (especially planning and coordination of tasks) is retained better, sleep quality is improved, depression symptoms decrease and self-esteem improves. Experiments in animals have shown that growth factors significant to cells in the central nervous system are affected by physical activity (66). In the hippocampus (important to memory formation), the gene expression of a large number of factors increases. There are also studies that indicate that the new formation of brain cells increases in animals that are allowed to run (67). Other studies have shown that the new formation of vessels increases in the cerebral cortex after exercise training, which can be of significance to the supply of nutrients. In cells in the peripheral nervous system, studies in animals have shown that markers for oxidative capacity/aerobic capacity increase.

Break out of such injury in aged individuals is more than that in other age groups, therefore, such injury may not be diagnosed in most individuals and young persons for not being diagnosed [12]. In the most common classifying system, Wilts classification, spondylolisthesis is divided into six types based on etiology [14]: dysplastic, isthmic, degenerative, traumatic, pathologic, and iatrogenic. According to the degree of upper vertebrae slipping, Meyerding classifying system divides spondylolisthesis into five grades as follows [5]: Grade 1: 0-25% Grade 2: 26-50% Grade 3: 51-75% Grade 4: 76- 100% Grade 5: over 100% Of the other reasons of back pain, lumbarization and sacralization of lumbosacral spines can be referred to that generally called lumbosacral transitional vertebrae (Figure 3). Grading of Spondylolisthesis (Figure reproduced with permission: © 2017 Clinique du Dos Orthopole. The highest sacral segment and lowest lumbar segment are involved in lumbarization and sacralizasion, respectively (Figure 4). The referring patients with their imaging result were entered into the experiment, and demographic information of patients including age, sex, and data related to pain were registered in the information form. The precise etiology of chronic back pain in most of the individuals is not well recognized, and spondylolysis and spondylolisthesis may result in such signs. Few studies were administered in this respect, and there is a possibility to do studies with greater sample size especially in developing countries which have different lifestyles. The occurrence of spondylolysis and spondylolisthesis in referring individuals were 60 (8. Information of the most frequent sites of spondylolisthesis and spondylolysis are presented in the table 1. Radiologic findings related to prevalence of lumbosacral spine pathologies are depicted in figure 5. In analyzing the relationship between age and incidence of spondylolisthesis and spondylolysis in both sexes, age of women afflicted with spondylolisthesis was significantly more than that of healthy women. Age of individuals suffering from spondylolysis was significantly less than that of healthy ones in both men and women (Table 3).

The most common level of involvement in spondylolisthesis among patients in this study was L4-L5, and the level of L2-L3 had the least common of involvement. Of 60 patients with spondylolysis, the most involved vertebra was L5 observed in 39 individuals (65%). Moreover, spondylolisthesis prevalence in women was significantly higher han that in men. On investigating the relationship between age and various pathologies, women suffering from spondylolisthesis were found to be significantly older than men, and the individuals who suffered from spondylolysis Iran J Neurosurg. Prevalence of Different Pathologies Observed by X-ray Imaging in Patients Afflicted with Chronic Low Back Pain (694 Individuals) with 95% Confidence Interval in both women and men were significantly younger. Prevalence of spondylolysis in communities, ethnicities, age groups, and both sexes is different, and various studies have reported the prevalence as 5-20% (10). However in our study, radicular pain occurred in more than 60% of individuals, and the prevalence of spondylolysis was less common. This research realized that the prevalence of spondylolysis in both sexes were the same, while other studies (10,11,13) reported that the prevalence of this injury in men was more than that in women. The authors of the present work concluded that individuals with spondylolysis were significantly younger than individuals without it, confirming the findings of most of the prior researches. More importantly, there was a statistically significant relationship between age and spondylolisthesis in women. Furthermore, no significant relationship existed between spondylolysis and spondylolisthesis, and only 10% of the individuals suffering from spondylolisthesis had spondylolysis. In most of the studies like the present one, women are more involved than men, and prevalence of spondylolisthesis is associated with increasing age in females (18-20). The most common etiology of spondylolisthesis is degeneration of joint surface, and spondylolysis is less important to make spondylolisthesis. However, the prevalence of spondylolisthesis among women was significant and associated with increasing age.
