odontoid pannus treatment

The patient's occipital headaches persisted despite We report a Pathology. The tectorial membrane and alar ligaments provide most of the stability to the atlanto-occipital joint, and injury to these ligaments results in instability due to low inherent osseous stability 3.. Pre-operative sagittal, T1- ( b) and T2-weighted ( c) MRI scan demonstrating a retro-odontoid pannus severely compressing the spinal cord as well as subaxial degenerative Most authors have recommended treatment with NSAIDs and/or steroids (especially prednisolone) ( 13, 24, 25 ). A key step in the pathogenesis of rheumatoid arthritis is pannus formation. pannus formation and subsequent damage to the adjacent cartilage and bone. Treatment objectives are to decompress the neural elements and stabilise the spine to prevent further spinal cord injury. There is a large ventral mass behind the axis body and the odontoid process, representing tough pannus, and marked compression of the ventral cervicomedullary junction. Pannus describes an abnormal layer of granulation tissue. Treatment options for type II odontoid fractures can be nonsurgical or surgical. AAS with marked intraspinal pannus formation and syno-vitis around the odontoid peg without neurological com-pression. A type II odontoid fracture is a break that occurs through a specific part of C2, the second bone in the neck. All patients were seropositive. Learn more about this growth, its side effects, and treatment options. Retro-odontoid pannus concentrates its action between the dens and C1 anterior arch, or the dens and transverse ligament. Its development causes spinal canal narrowing and consequent neurological symptoms. Direct spinal cord decompression is indicated when neurological deficits are present [ 20 ]. All of them had soft tissue formation (pannus) around the odontoid peg. Careful examination of the pre-operative imaging revealed a high likelihood of an intradural component to this pannus. 1 B). Methods: We searched the database of Clinical and radiological follow-up are important to assess the impact on the cervical spine. Nonsurgical measures include immobilization, prevent or restrict movement, in a cervical collar or halo vest. Gross well-defined erosion of the dens and atlanto-axial joints typical of rheumatoid arthritis. The portion of Rheumatoid arthritis. Rheumatoid arthritis. treatment observation Anatomy Osteology axis has odontoid process (dens) and body contains a transverse foramen which vertebral artery travels through embryology develops from five ossification centers subdental (basilar) synchondrosis is an initial cartilaginous junction between the dens and vertebral body that does not fuse until ~6 years of age Introduction. T1-weighted sagittal magnetic resonance image of the cervical spine shows basilar invagination with cranial migration of an eroded odontoid peg. The AO Spine classification of It is usually seen overlying joint surfaces (usually in the setting of rheumatoid arthritis, though pannus can be a feature of other inflammatory arthropathies), prosthetic heart valves, or overlying the cornea 1 . Abstract. Anterior Odontoid Screw Fixation Typically, these lesions are treated utilizing combined transoral resection of the Transoral Pain and stiffness often worsen following rest. Bones of the spine are called vertebrae. Pre-operative examination reveals neck pain, spasticity signs, and finger clumsiness. Minor extrinsic compression to the upper cervical cord. Surgery may be required if the fracture has resulted in neurologic symptoms and/or the spine has become unstable. surgical treatment of rop can be classified into two modalities: 1) direct excision of the mass and 2) posterior decompression and fusion aiming spontaneous tumor regression. Go to: Discussion. C-spine CT scan ( gure 3 ) did not show erosions of the odontoid. Objective: The potential significance of relationship of atlantoaxial instability with retro-odontoid pseudotumor, pannus, and/or cyst (RPC) is analyzed. Those lubricating sacs can become swollen and even scarred down, which produces whats called a Pannus. Request PDF | Retro-Odontoid and Retro-C2 Body Pseudotumor, Pannus, and/or Cyst. However, some authors have reported resolution of pannus associated with rheumatoid arthritis and other forms of chronic atlanto-axial instability only after posterior stabilization. Discussion. Though there are reports of pannus debulking using immunosuppression, only the former treatment objective (spinal decompression) rheumatoid arthritis (RA): in which case it may be termed pannus trauma os odontoideum tenosynovial giant cell tumor atlantoaxial hypermobility compensating for subaxial ankylosis diffuse idiopathic skeletal hyperostosis ossification of the posterior longitudinal ligament cervical spondylosis / osteoarthritis deposition diseases By Wissam Elfallal, Samer Elfallal. Most commonly, the wrist and hands are involved, with the same joints typically involved on both sides of the body. Post-operative day one, he complains of significant weakness with raising his left arm overhead and on further examination, you notice a clear Although literature supports resolution of a retro-odontoid pannus Periodontoid pannus formation plays an important role in compromising the anteroposterior diameter of the spinal canal and in causing neurologic deficits. The treatment of AAI with synovial pannus formation is not standardized and various medical and surgical treatment modalities have been described in the literature. Symptoms can include Valsalva-induced headache, bulbar nerve paresis, and cerebellar dysfunction [ 2 ]. Patients with type III odontoid fractures and ruptured transverse ligaments are also best treated with a posterior procedure; if the ligament is intact but there is motion at the fracture site, anterior screw fixation can be considered. In order to treat retro-odontoid pannus associated with either subaxial subluxation or C0-C1 fusion, an occipito-cervical fusion is needed; moreover, it may be useful in cases of The tip of the peg indents the medulla, and there is narrowing of the foramen magnum due to the presence of the peg. Unfortunately, this led to the common but erroneous belief that treatment of rheumatoid involvement of the craniocervical junction should be conservative. Abstract: Despite the growing use of computed tomography (CT) and magnetic resonance imaging (MRI) in the study of spinal disorders, radiography still plays an important role in many conditions affecting the spine. The clinical presentation of CIM is variable, especially when different age groups are compared. However, the study and interpretation of spine radiograph is receiving less attention and radiologists are increasingly unfamiliar with the typical findings in Figure 5. modality. It is usually seen overlying joint surfaces (usually in the setting of rheumatoid arthritis, though pannus can be a Lateral view plain x-ray of C-spine after posterior spinal fusion surgery. Treatment with tumour necrosis factor (TNF) was delayed until postoperative spinal bone fusion was achieved. Th1 cells release interferon- (IFN-) in order to activate macrophages and synovial cells can be performed of the neck to rule out odontoid ligament laxity. The bone involved in odontoid fracture is the hands, wrists, and feet. It usually spontaneously resolves although duration is variable (from days to months) 1.In some cases, the inflammatory pannus can result in cervical cord compression, and this may require surgical decompression 1,2.. History and etymology Treatment objectives are to decompress the neural elements and stabilise the spine to prevent further spinal cord injury. A retro-odontoid pseudotumor is most commonly associated with rheumatoid arthritis and atlanto-axial subluxation [].The pathogenesis of retro-odontoid pseudotumor in rheumatoid If the problem continues send us an email to let us know . Structural Issues and an Odontoid Pannus On the front and back of the Dens of C2, there is a bursa (shown in yellow). Large soft tissue mass encircling the eroded dens consistent with "pannus", i.e. Large soft tissue mass encircling the eroded dens consistent with "pannus", i.e. The tip of the peg indents the medulla, and there is narrowing of the foramen magnum due to the presence of the peg. There is minimal pannus. Oka et al. Retro-odontoid pseudotumor formation consists of an abnormal growth of granulation tissue typically posterior to the odontoid process, resulting as a manifestation of atlantoaxial instability. Odontoid pannus formation is rare in AS. Though there are reports of pannus debulking using Rheumatoid arthritis (RA) is a long-term autoimmune disorder that primarily affects joints. Careful examination of the pre-operative imaging revealed a high likelihood of an intradural component to this pannus. Pannus describes an abnormal layer of granulation tissue. Retro-odontoid pseudotumor, or mass-like retro-odontoid soft tissue thickening, is an uncommon but important imaging finding that may be associated with rheumatoid arthritis, crystal Both conventional radiography and magnetic resonance imaging (MR) were performed pre- and postoperatively. Several etiologies are known to cause basilar invagination, an anomaly of the craniovertebral junction resulting in odontoid-mediated compression of the brainstem and/or cervicomedullary junction. On the other hand, a different group of patients have been identified in whom RP is observed without radiologic findings of atlantoaxial instability. hypertrophied synovium. 1, It typically results in warm, swollen, and painful joints. Pannus | Radiology Reference Article | Radiopaedia.org Pannusdescribes an abnormal layer of granulation tissue. It is usually seen overlying joint surfaces (usually in the setting of rheumatoid arthritis, though pannus can be a feature of other inflammatory arthropathies),prosthetic heart valves,o In most of the cases, the clinical symptoms improve within 47 days ( 11, 13, 26 ). Patient Data. Background: Retro-odontoid pseudotumor (RP) can be caused by several diseases, especially rheumatoid arthritis, and is usually associated with the presence of atlantoaxial instability. There is minimal pannus. This can add to the pressure on the Medulla and the Cervical Medullary Syndrome as shown below: The disease may also affect other parts of the body, including skin, eyes, Treatment and prognosis. Classification. The Traynelis classification describes injuries according to the displacement of the occipital condyles relative to the atlas.. findings. Competing interests (SBQ18SP.57) A 63-year-old male undergoes a C4-C7 posterior fusion and laminectomy secondary to significant spinal cord stenosis. A retro odontoid pseudo tumor is a mass lesion lying posterior to the odontoid process along the dura. Treatment options for type II odontoid fractures can be nonsurgical or surgical. Nonsurgical measures include immobilization, prevent or restrict movement, in a cervical collar or halo vest. Surgery may be required if the fracture has resulted in neurologic symptoms and/or the spine has become unstable. ( 17) summarized in their review that 85% of the patients with CDS were treated with NSAID alone or NSAID with another drug. Crowned dens syndrome usually requires only medical management with anti-inflammatory agents. The odontoid process of C2, also called the dens, is a peg-like protuberance that extends cranially from the body of C2 to articulate with the anterior aspect of C1. 1 Surgical intervention in the craniovertebral junction is inherently challenging and has traditionally been accomplished through a transoral resection and Nonsteroidal anti-inflammatory drugs (NSAIDs) are common treatment options that help to reduce pain and inflammation. NSAIDs are available as a pill, skin patch, or topical. Doctors may prescribe corticosteroid medication to decrease inflammation and help slow pannus growth. The duration of the RA disease was 3-48 years (mean: 18.5). T1-weighted sagittal magnetic resonance image of the cervical spine shows basilar invagination with cranial migration of an eroded odontoid peg. Surgical treatment is often indicated, depending on the patients symptoms [ 1 ]. Dynamic C-spine x-rays ( gure 4 ) showed an anterior atlanto-odontoid distance (AAOD) of 1.1 cm on exion and 0.65 cm on extension, consistent with AA The age ranged from 50 to 79 years (mean: 66). Although literature supports resolution of a retro-odontoid pannus with C1-2 immobilization, there is scant literature on ventral dural erosion, and the effects of fusion on an intradural component. There was extensive pannus formation around the odontoid peg, which extended into the spinal canal ( Fig. A Google djmentesen hasznlhat szolgltatsa kpes a szavak, kifejezsek s weboldalak azonnali lefordtsra a magyar s tbb mint 100 msik nyelv kztt. Pannus is a growth between the joints that occurs in someone with rheumatoid arthritis.
