Spondylolisthesis imaging

Dec 20, 2013. Traditionally, the “dynamic” and “static” types of spondylolisthesis have been lumped into a single group in the literature. The goal of this study was to define the radiographic characteristics of “dynamic” and “static” spondylolisthesis with the use of magnetic resonance imaging MRI and flexion/extension. Spondylolisthesis is a descriptive term referring to slippage (usually forward) of a vertebra and the spine above it relative to the vertebra below it. Spondylolisthesis has many etiologies, all of which ultimately lead to a loss of the stability offered by the locking mechanism of the articular processes of the vertebrae that allow the superior vertebrae to slide forward over the inferior vertebrae. The etiologies can be classified as congenital (dysplastic), spondylolytic (isthmic), degenerative, traumatic, pathologic, or iatrogenic (eg, postoperative). It affects the region of the pars interarticularis, which is roughly the region of the junction of the pedicle and lamina, where the articular and transverse processes of the vertebrae arise. A defect at this point functionally separates the vertebral body, pedicle, and superior articular process from the inferior articular process and the remainder of the vertebrae.

This chapter reviews the imaging techniques used in the evaluation of spondylolisthesis. Available modalities include radiography, magnetic resonance imaging MRI, computed tomography, and. The medical cost associated with back pain in the United States is considerable and growing. Although the differential diagnosis of back pain is broad, epidemiological studies suggest a correlation between adult and adolescent complaints. Injury of the pars interarticularis is one of the most common identifiable causes of ongoing low back pain in adolescent athletes. It constitutes a spectrum of disease ranging from bone stress to spondylolysis and spondylolisthesis. Repetitive bone stress causes bone remodeling and may result in spondylolysis, a non-displaced fracture of the pars interarticularis. A fracture of the pars interarticularis may ultimately become unstable leading to spondylolisthesis. Results in the literature support the use of bone scintigraphy to diagnose bone stress in patients with suspected spondylolysis. Single photon emission computed tomography (SPECT) provides more contrast than planar bone scintigraphy, increases the sensitivity and improves anatomic localization of skeletal lesions without exposing the patient to additional radiation. It also provides an opportunity for better correlation with other imaging modalities, when necessary.

Pediatric Spondylolisthesis & Spondylolysis - Spine - Orthobullets

Spondylolisthesis imaging

Feb 1, 2016. Imaging studies are necessary for an accurate assessment and diagnosis of spondylolisthesis. Consensus is lacking on the optimal imaging protocol for spondylolysis/spondylolisthesis, in part because of the issue of radiation exposure to the pediatric spine, the many pros and cons for each modality, and. A hangman's fracture is a specific type of spondylolisthesis where the second cervical vertebra (C2) is displaced anteriorly relative to the C3 vertebra due to fractures of the C2 vertebra's pedicles. Symptoms of anterolisthesis include: Other symptoms may include tingling and numbness. An individual may also note a "slipping sensation" when moving into an upright position. Sitting and trying to stand up may be painful and difficult. Anterolisthesis location includes which vertebrae are involved, and may also specify which parts of the vertebrae are affected. Isthmic anterolisthesis is where there is a defect in the pars interarticularis.

Spondylolisthesis is a denotes the slippage of one vertebra relative to the one below. Spondylolisthesis can occur anywhere but is most frequent, particularly when due to spondylolysis, at L5/S1 and to a lesser degree L4/5. Terminology Althoug. Spondylolysis is the medical term for a spine fracture or defect that occurs at the region of the pars interarticularis. The pars interarticularis is region between the facet joints of the spine, and more specifically the junction of the superior facet and the lamina. Spondylolisthesis is the medical term used to describe the forward slippage (anterior translation or displacement) of one spine bone (vertebrae) on another. Quite often, a person who has spondylolysis (pars fracture) will also have some degree of spondylolisthesis (forward slippage of one spine bone on another). However, a person may have a spondylolysis without having spondylolisthesis, and a person may have spondylolisthesis without having a spondylolysis.

This chapter reviews the imaging techniques used in the evaluation of spondylolisthesis. Available modalities include radiography, magnetic resonance imaging (MRI), computed tomography, and scintigraphy. Optimal utilization of these techniques can result in an accurate assessment with little or no risk to the patient. The strengths of each modality will be discussed along with the limitations so that the reader can gain a sense of how to proceed with the diagnostic workup. The diagnosis of spondylolisthesis is usually first made on radiography which may or may not be performed with the specific diagnosis in mind.

It's hard to tell if you have spondylolisthesis because you may not have any symptoms or overwhelming pain—most people don't. Spondylolisthesis is usually discovered when you're being tested for something else and the doctor notices the slipped vertebra on an x-ray. X-rays are the best way to diagnose spondylolisthesis. During the x-ray, you'll probably stand facing the side—that's so the doctor can get a lateral (side) view, which most clearly shows the slip. Looking at the lateral x-ray below, you can see that one of the vertebra has slipped off the spinal column. To see if your spondylolisthesis is unstable and moving, the doctor may perform flexion and extension views from the side. A flexion x-ray is taken with you bending forward; an extension x-ray is taken with you bending backwards. For further confirmation of spondylolisthesis, you may need to have a CT scan. If the slipped vertebra is pressing on nerves, the doctor may order a myelogram. In this test, you'll have a special dye injected into the area around your nerves—your nerves are in a sac, so the dye will go into that sac.

A defect at this point functionally separates the vertebral body, pedicle, and superior articular process from the inferior articular process and the remainder of the vertebrae. Thus, the defect cleaves the vertebra into 2 parts. The portion of the vertebra posterior to the defect remains fixed, and the anterior portions are free to potentially slip forward relative to the posterior structures and spine below. Note that a bilateral pars defect is needed to allow slippage.

Magnetic resonance imaging, or MRI, uses a magnet to examine the inside of your body to diagnose conditions like spondylolysis and spondylolisthesis. : Gouty spondyloarthropathy is generally believed to be uncommon. Together with the fact that it can mimic a variety of disease entities, it imposes significant diagnostic challenge in our clinical practice. In this article, we report two patients diagnosed with spinal gout, and both were initially suspected to have a pyogenic infection. Read More A 54-year-old woman presented to a Sports Physician with a 4-year history of haemochromatosis, and she had a medical history that included a congenital spondylolisthesis resulting in a fusion of L4-S1 at age 16 years, episodic mechanical low back pain and an absence of other significant musculoskeletal symptoms. On presentation, she reported 18 months of severe low back pain that started after a scuba diving trip.

Explaining Spinal Disorders: Degenerative Spondylolisthesis

Spondylolisthesis imaging

Spondylolysis and spondylolisthesis are conditions that affect the moveable joints of the spine that help keep the vertebrae aligned one on top of the other. Symptoms. Spinal stenosis is a condition in which there is narrowing of the spinal canal and therefore a reduction in space for the nerves. It is usually due to degenerative changes (acquired). The intervertebral disc can be thought of as a car tyre - over time it deflates and bulges. As this occurs the height is lost at the front of the spine and the facet joints at the back of the spine start to take more load. Facet joint degeneration then occurs and the joints and ligaments can enlarge. The ligaments at the back of the spine tend to buckle inward as the disc height is reduced and they become lax. Narrowing of the spinal canal and space for the nerves then occurs due to a combination of the disc bulge, facet enlargement (hypertrophy) and ligament buckling (ligamentum flavum hypertrophy). Spinal stenosis can also be present from birth (congenital) due to a smaller spinal canal.

Spondylolisthesis imaging

Lumbar spondylolisthesis is a common finding on plain radiographs. The condition has a variety of causes which can be differentiated on the basis of imaging findings. As the treatment is dependent upon the type of spondylolisthesis, it is important for the radiologist to be aware of these features. The University of Chicago Medicine orthopaedic spine team offers a wide range of non-surgical, minimally invasive and traditional proven surgical techniques for the treatment of back and neck problems. We maximize the use of non-surgical interventions for reducing pain and restoring function. When surgery is chosen, in some instances it can be performed using minimally invasive techniques that involve smaller incisions than those in traditional open surgery. In all cases, patients can expect the most effective solution: a treatment that has the highest probability of providing the most improvement and durability for the longest period of time. We believe in a patient-centered process of informed and shared decision-making. Patients receive a complete evaluation as well as a thorough explanation of their symptoms and of non-operative and operative treatment options. We are committed to listening to and guiding the patient, with respect and compassion. Through this process, we empower our patients to make the best decision for their treatment.

Despite the predominant use of standing flexion-extension radiography for quantifying instability in isthmic and degenerative spondylolisthesis, other functional radio-graphic techniques. Bendo JA, Ong B. Importance of correlating static and dynamic imaging studies in diagnosing degenerative lumbar spondylolisthesis. Optimal positioning yields a single line denoting the posterior cortex of each vertebral body; a line along these posterior cortices will form a smooth, uninterrupted curve when the vertebral alignment is normal. However, lateral views are often compromised by patient rotation. With rotation, two posterior vertebral body cortices may be evident at the rotated levels; a line connecting the midpoints of the spaces between these cortices can be visualized and should again form a smooth curve when the alignment is normal. Alternatively the midpoints of the anterior aspects of the vertebral bodies should be smoothly aligned (Fig. Vertebral anatomic landmarks demonstrated on lateral radiographs include the pedicles, superior and inferior articular facets, facet joints, neural foramina, intervertebral disc spaces, and spinous processes. The portion of the neural arch between the superior and inferior articular facets, the pars interarticularis (plural, pars interarticulari; Latin plural partes interarticulares) can be seen, of particular interest in spondylolisthesis (Fig.

Imaging characteristics of “dynamic”

Spondylolisthesis imaging

Imaging characteristics of “dynamic” versus “static” spondylolisthesis analysis using magnetic resonance imaging and flexion/extension films Cervical Spondylolisthesis is a condition involving a vertebra in the spinal column that is not properly aligned with its neighbor. This allows it to slip around with movement, thus causing pressure on nerve roots and on the spinal cord itself. This condition can lead to neck pain as well as other symptoms. Spondylolisthesis is most commonly detected in the lumbar region or lower back because that is the area which bears the greatest amount of stress. When it occurs, it is usually secondary to a neck injury, arthritis, infection, or degeneration of the cervical spine due to aging. Some people with spondylolisthesis have a congenital defect in their cervical spine called spina bifida occulta. This is a condition where the vertebrae in the spinal column do not close completely, leaving small gaps in the bones. It is possible to have this congenital defect and not be aware of it. Cervical spondylolisthesis characteristically causes neck pain and stiffness that radiates into the shoulders.

Year-old woman was recruited for a research study of muscle activation in persons with low back pain. She described a progressive worsening of left lower lumbar pain, which began 5 years prior without any precipitating incident, and intermittent pain at the left gluteal fold diagnosed as a proximal hamstring tear 2 years. Normally, the bones of the spine (the vertebrae) stand neatly stacked on top of one another. Spondylolisthesis alters the alignment of the spine. In this condition, one of the spine bones slips forward over the one below it. As the bone slips forward, the nearby tissues and nerves may become irritated and painful. This guide will help you understand What parts of the spine are involved? The human spine is made up of twenty-four spinal bones, called vertebrae. The section of the spine in the lower back is called the lumbar spine. Vertebrae are stacked on top of one another to create the spinal column. The lumbar spine is made of the lower five vertebrae. Doctors often refer to these vertebrae as L1 to L5. These five vertebrae line up to give the low back a slight inward curve.
