and causes neurologic dysfunction. The most common causes of myelopathies are as follows:. Congenital and developmental defects, syringomyelia, neural tube formation defects. Compromise of the spinal cord. Cervical spondylosis, inflammatory arthritis, acute disc herniation. Physical agents, decompression sickness. Electrical injury, radiation. Toxins, nitrous oxide, triorthocresyl phosphate.

The most frequent etiology of myelopathy is tekenbeet related to degenerative disease of the spine from osteophyte or extruded disc material causing compression of the spinal cord in the cervical or thoracic spine. The next common etiologies are spinal cord compression due to extradural masses caused by metastatic disease to bone or blunt trauma. In these cases, emergency imaging should be performed to assess the nature of the lesion causing the myelopathy and plan the most appropriate treatment. Also urgent imaging should be performed when an abscess in the spinal canal is suspected. Less urgent is imaging of primary neoplasms of the meninges, roots, or spinal cord, as well as noninfectious inflammatory processes, such as multiple sclerosis, and neurodegenerative, vascular, nutritional, or idiopathic disorders leading to myelopathy. Although a survey of the entire spinal cord can be performed with imaging, it is more appropriate to define from the clinical findings what levels of the spine and spinal cord should be imaged. This approach helps limit the likelihood of false-positive imaging findings that may encourage needless attempts to fix what is not broken. Similarly, the most appropriate imaging study and protocol should be selected in order to provide a timely and accurate diagnosis. To do so requires detailed knowledge regarding the strengths and limitations of the multiple imaging modalities available. This chapter outlines an approach to proper study selection based on the likely etiology of myelopathy from the clinical findings.

Myelopathy definition of myelopathy by medical dictionary


Myelopathy is a general term for dysfunction of the spinal artrose cord, which may be focal or diffuse in midden character and due to intrinsic or extrinsic processes. From: Handbook of Clinical neurology, 2014, related terms: learn more about myelopathy,. Oyinkan Marquis1, patrick. Handbook of Clinical neurology, 2016, abstract, myelopathy is an inclusive term, referring to pathology leading to a neurologic deficit related to the spinal cord. The clinical diagnosis of myelopathy requires a detailed history and physical examination to define the clinical syndrome. Neuroimaging is indicated in most instances of new-onset myelopathy. It is indicated also when the worsening of a myelopathy is unexplained. Advances in neuroimaging have proved to play a vital role in diagnosis. Appropriate diagnosis and treatment are dependent upon an adequate imaging evaluation to establish the presence of mechanical stability, extrinsic spinal cord compression, or an intramedullary lesion.

Immunoglobulin A (IgA) nephropathy has been reported in association with. Neurologic involvement neurologic complications may occur secondary to fractures of a fused spine, which may be very difficult to detect with standard radiography. Patients are also prone to atlantoaxial subluxation, which may result in cervical myelopathy. Cauda equina syndrome may also occur in patients with severe long-standing. Gastrointestinal involvement Asymptomatic inflammation of the proximal colon and terminal ileum has been observed in as many as 60 of patients with as and USpA. Patients with established as only rarely develop Crohn disease or ulcerative colitis. Metabolic bone disease Although as is associated with new bone formation at sites of spinal and peripheral enthesitis, osteopenia and osteoporosis have been documented in patients with long-standing spondylitis, resulting in an increased risk of fracture. Patients with as who have severe spondylitis and who present with acute exacerbations of back or neck pain should be re-evaluated for possible fracture, especially in the setting of trauma. Standard radiography may not be revealing; computed tomography (CT) or mri may be required to aid in diagnosis.

Attacks usually resolve over 2-3 months with treatment, and residual visual impairment is unlikely unless treatment is inadequate or delayed. The uveitis that develops in rea is similar to the uveitis that develops in as, whereas the uveitis that develops in PsA and in spondyloarthropathy associated with ibd tends to be more chronic and bilateral and often involves posterior elements. Cardiovascular involvement Clinically significant cardiovascular involvement occurs in fewer than 10 of as patients, typically those with severe long-standing disease. However, subclinical disease can be detected in many patients and may occur as an isolated clinical entity in association with hla-b27. Aortitis of the ascending aorta may lead to distortion of the aortic ring, resulting in aortic valve insufficiency. Mitral valve insufficiency rarely occurs. Fibrosis of the conduction system may result in various degrees of atrioventricular block, including complete heart block.

Pulmonary involvement Restrictive lung disease may occur in patients with late-stage as, with costovertebral and costosternal involvement that limits chest expansion. Bilateral apical pulmonary fibrosis rarely occurs in the setting of severe disease. These lesions may cavitate and become colonized by bacteria or fungi (eg, Aspergillus resulting in cough, dyspnea, and hemoptysis. Renal involvement Amyloidosis is a very rare complication of as in patients with severe, active, and long-standing disease. These patients generally have active spondylitis, active peripheral jacob joint involvement, a higher erythrocyte sedimentation rate (esr and an increased C-reactive protein (CRP) level. This may result in renal dysfunction with proteinuria and renal insufficiency or failure.

Isolated small-joint involvement of the hands, feet, or dactylitis strongly suggests reactive arthritis (rea psoriatic arthritis (Psa or undifferentiated spondyloarthropathy (USpA). Destructive arthritis may affect the hips or shoulder girdle, which may result in limited range of motion and flexion deformities. Extra-articular manifestations, screen for extra-articular manifestations of as by performing specific examinations (eg, ophthalmologic, cardiac, gastrointestinal GI). Such manifestations may include the following: uveitis, cardiovascular disease, pulmonary disease. Renal disease, neurologic disease, gI disease, uveitis. Uveitis (also called iritis or iridocyclitis) is the most common extra-articular manifestation of as, occurring in 20-30 of patients.

71, 72, of all patients with acute anterior uveitis, 30-50 have or will develop. The incidence is much higher in individuals who are. Patients with uveitis may also have or may develop other spondyloarthropathies, including rea (5-10 uspA (2-5 and PsA ( 1 although this is less common. Isolated inflammatory bowel disease (IBD) is also associated with uveitis. The uveitis associated with as is usually acute in presentation and unilateral, and symptoms include a painful red eye with photophobia, increased lacrimation, and blurred vision. The involvement is usually anterior, rarely including posterior elements.

Enthesitis and synovitis account for some of the peripheral joint involvement. Peripheral joint disease occurs in 33 of patients, most commonly in the hips. Hip involvement usually occurs in the first 10 years of the disease course and is typically bilateral. Other joints may be involved, including the following: Shoulder girdle (glenohumeral, acromioclavicular, and sternoclavicular joints). Costovertebral joints, costosternal junctions, manubriosternal joints, symphysis pubis. Temporomandibular joint, peripheral joints are uncommonly involved. When they are involved it is in an asymmetric oligoarticular pattern. Dactylitis (sausage digit) is very uncommon in patients with.

Remeasure compulsief the distance between the marks. Normal flexion increases the distance by at least. Loss of chest expansion ( 3-cm difference between minimum and maximum chest diameter) is usually found only in patients with late-stage disease. It is generally not helpful in diagnosis. Peripheral entheses and joints, peripheral enthesitis occurs in approximately 33 of patients. These lesions are painful and tender to palpation and may be associated with swelling of the tendon or ligament insertion. The most common and characteristic peripheral sites of enthesitis are the insertion of the Achilles tendon on the calcaneus and the insertion of the plantar fascia on the calcaneus. Certain anatomic areas may be more prone to enthesitis because of biomechanical stress. Carefully examine patients for tenderness upon palpation.

Tenderness in the si joints is common. Peripheral enthesitis stoppen is often identified by tenderness and swelling of tendons and ligamentous insertions. 4, spine, stiffness of the spine and kyphosis resulting in a stooped posture are characteristic of advanced-stage. Earlier in the course of the disease, indirect evidence of sacroiliitis and spondylitis may be observed, including tenderness of the si (elicited by either direct pressure or indirect compression) or a limited spinal rom. Some patients may have a deformity of the spine, most commonly with a loss of lumbar lordosis and accentuated thoracic kyphosis. The rom of the lumbar spine can be assessed using various methods, of which the Schober test is the most popular. (This test is not specific for.). Perform the Schober test by marking a 10-cm length of the lumbar spine (with the patient in the erect position starting at the fifth lumbar spinous process. Instruct the patient to flex his or her spine maximally.

Chronic involvement of the scan spine eventually can lead to decreases in rom and fusion of the vertebral bodies. Involvement of the cervical and upper thoracic spine can lead to fusion of the neck in a stooped forward-flexed position (see the images below). This position can significantly limit the patients ability to ambulate and look straight ahead. Patient with ankylosing spondylitis affecting cervical and upper thoracic spine. Patient's spine has been fused in flexed position. View Media gallery, posterior view of patient with ankylosing spondylitis affecting cervical and upper thoracic spine.
