The procedure is performed using fluoroscopy, a special x-ray machine that allows x-ray images to be viewed instantly on a television monitor. A discogram would not be recommended for an adolescent or child. If a patient has significant leg pain, weakness, and/or numbness, electromyography and nerve conduction velocity (EMG/NCV) tests may be recommended. Emg/ncv tests are useful to determine which nerve is affected, and how severely it is damaged or irritated. The test will often clarify where a nerve is actually being compressed - whether it is in the back, buttock, or leg. Diagnosis, the diagnosis of spondylolysis and/or spondylolisthesis may be suspected, particularly if the above-mentioned physical findings are present. An x-ray or ct scan is required to confirm the diagnosis, as well as to grade the severity of the condition.

A computed Tomography (CT) scan is the best test to verify that a pars defect/fracture is or is not present. The amount of forward translation (spondylolisthesis) is quantified by evaluating the percentage of slippage of one bone essay on another. The meyerding classification is used determine whether it is a grade i (0-25 Grade ii (25-50 Grade iii (50-75 Grade iv (75-100 or Grade v (more than 100). The slip angle is determined by how angulated the L5 bone is. An mri test is useful to evaluate the severity of nerve compression, but is less accurate at detecting a pars fracture than a ct scan. A bone scan may be ordered to determine if the spondylolysis pars fracture is recent (acute or if it is old (chronic). A recent fracture would generally have a significant radionucleotide uptake and appear as a "hot spot" in the lower lumbar region. There are database no laboratory tests used to diagnose spondylolysis or spondylolisthesis. Occasionally, specific tests are ordered to rule out infection or other medical/rheumatologic conditions. Special Tests, a discogram may useful in an adult patient to determine if the discs adjacent to the are also causing pain. A doctor performs this procedure by injecting radiopaque dye, under pressure, into the discs of the lumbar spine.
Physical Findings, children with spondylolysis and spondylolisthesis often have a stiff-legged gait and backward pelvic tilt, causing the buttocks to appear very flat. If the spondylolisthesis is severe, a "step-off" may be felt over the lower back region. The hamstring tightness may be so severe in some children that forward bending is limited and picking something off the floor is impossible. The neurological examination of strength, sensation, and reflexes is usually always normal in children. Adults with spondylolysis and/or spondylolisthesis frequently have lumber tenderness and an antalgic gait (pain causing abnormal walking but rarely have a noticeable fruit deformity unless the slippage is severe or has been present since childhood. Adults may have numbness, weakness, and/or neurogenic claudication, especially if the associated arthritis and spinal stenosis is severe. Imaging Studies, spondylolysis and spondylolisthesis is frequently identified with regular lumbar x-rays, especially the lateral (side view) x-rays. It is sometimes difficult to see a non-displaced or minimally displaced pars fracture (spondylolysis therefore oblique and flexion/extension x-rays are usually obtained.
It is lab more common for a child or young adult to have a spondylolysis (pars fracture) without having spondylolisthesis, whereas adults are writing frequently diagnosed with spondylolisthesis without spondylolysis. Although it is confusing, both of these conditions are frequently seen in combination, and the treatments for both conditions are often the same. However, it is much more common for adults to be treated surgically; children with rarely require surgery unless the slippage is severe. Causes, there are a number of causes of spondylolisthesis, and a classification system was developed by wiltse. There are six types (or causes type i is congenital (birth defect) or dysplastic (developed abnormally early in life type ii is isthmic (caused by a pars fracture and instability type iii is degenerative (caused by arthritis type iv is traumatic (acute facet fracture/injury. Symptoms, back pain is the most common presenting symptom, particularly in adults. Children may or may not have significant back pain; the predominant symptom(s) may be difficulty walking, postural deformity, and/or hamstring tightness. Adults frequently have leg pain, numbness, and/or weakness (sciatica, radiculitis, or radiculopathy) while children rarely have leg symptoms.
1976 Jun 117 23-9 Yochum t, rowe l, essentials of skeletal Radiology. Lippincott Williams and Wilkins; 3rd revised edition edition pgs 478-9). Overview, 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.

Nonsurgical treatments are usually recommended first. These may include: Activities should be reduced or stopped until your symptoms reduce. In most cases, a gradual return to activity is ideal. Chiropractic treatments and physical therapy can evaluate and address postural and compensatory movement abnormalities such as hyperlordosis and hip flexor and lumbar paraspinal muscle tightness. Acupuncture may also be of benefit in reducing pain and muscle spasm.
Physical modalities such as thermal treatment, electrical stimulation and lumbar traction can help with reactive muscle spasm, but typically are of short therapeutic duration when done in isolation, and should be coupled with therapeutic exercise. Epidural steroid injections, either interlaminal or transforaminal, performed under fluoroscopic guidance can help with severe radicular (leg) pain. Surgery to fuse the slipped disc may be needed if severe pain is present that does not get better with conservative treatment, a severe slip of the vertebra, or neurological changes. Prolotherapy injections are also used in the treatment of spondylolisthesis and the instability that is often associated with. These dextrose injections strengthen the supporting ligaments to stabilise the intervertebral segment. Conservative therapy for mild spondylolisthesis is successful in about 80 of cases. When necessary, surgery leads to satisfactory results in 85 - 90 of people with severe, painful spondylolisthesis.

Another visual indication is prominent, heart shaped buttocks. Spondylolistheses can often cause muscle spasms, or tightness in the hamstrings. Confirmation of a dillard spondylolisthesis is done using X-ray examination. X-ray examination gives the opportunity to grade a spondylolisthesis by severity into four groups. The grade of displacement of the vertebral body is given by dividing the vertebra below into quarters, and each quarter represents a grade. For example, a displacement of two party quarters is a grade two spondylolisthesis. What treatments are available? Treatment varies depending on the severity of the condition. Most patients get better with strengthening and stretching exercises combined with activity modification, which involves avoiding hyperextension of the back and contact sports.
The most common symptom of a spondylolisthesis is lower back pain. This is often worse after exercise, especially with extension of the lumbar spine. Other symptoms include tightness of the hamstrings and decreased range of motion of the lower back. Some patients can develop pain, numbness, tingling or weakness in the legs due to the anterior slippage of the vertebra causing nerve reviews compression. Severe compression of the nerves can cause loss of control over bowel or bladder function, or cauda equine syndrome, although this is extremely rare. How is it diagnosed? It is not common to see visible signs of a mild spondylolisthesis on physical examination of a patient, however some patients present with a palpable step defect which gives an indication of the possibility of a spondylolisthesis being present.
most common type of spondylolisthesis in the younger population is Isthmic, whereas in the older population the degenerative type is more common. Some individuals may have a spondylolisthesis, but with no symptoms and others may have low back pain, made worse by extension of the spine. Congenital and pathologic types are very rare. Risk factors that increase the likelihood of a degenerative spondylolisthesis occurring are increased bmi, age, and the angle of the lumbar lordosis in females (but not males according to a study by jacobsen et al 2007). Other risk factors include a history of repetitive trauma or hyperextension of the lower back or lumbar spine. Athletes such as gymnasts, weight lifters and football linesmen who have large forces applied to the spine during extension are at greater risk for developing isthmic spondylolisthesis as are Alaskan Eskimos (Yochum rowe, 2004). What are the symptoms?
Isthmic spondylolisthesis: In Isthmic spondylolisthesis, there is a defect in a portion of the vertebra called the pars interarticularis. If there is a defect without a slip, the patient has spondylolysis. Isthmic spondylolisthesis can be caused by repetitive trauma and is more common in athletes exposed to the hyperextension motions including gymnasts, and football linemen. Progression of an Isthmic spondylolisthesis rarely occurs after the age. Degenerative spondylolisthesis: Occurs due to arthritic changes in the joints of the vertebrae due to cartilage degeneration. Degenerative spondylolisthesis is more common in older patients. Traumatic spondylolisthesis: due to direct trauma or injury to the vertebrae. This can be caused by a fracture of the pedicle, lamina or facet joints that allows the front portion of the vertebra to slip forward with respect to the back portion of the vertebra.

The building blocks of a human spine are bones called vertebra. A human spine is made up of 33 vertebrae; 24 are mobile and 9 are fused. A spondylolisthesis is the forward or backwards displacement of one of these mobile vertebrae, in relation to the one below. Forward slippage of one vertebra on another is referred to as anterolisthesis, while backward slippage is referred to as retrolisthesis. The most common level for a spondylolistheis in the spine is the fifth and lowest lumbar vertebra. The most widely used classification system of spondylolisthesis was developed by wiltse et al in 1976. This system described five distinct types of spondylolisthesis: Dysplastic spondylolisthesis: caused by a defect in the formation of part of the vertebra called the facet that allows it to slip forward. This is a condition that a patient is born with (congenital).
