Pars defect without listhesis

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. It is more common for a child or young adult to have a spondylolysis pars fracture without having spondylolisthesis, whereas adults are 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. Causes There are a number of causes of spondylolisthesis, and a classification system was developed by Wiltse.

There are six types or causes: Symptoms Back pain is the most common presenting symptom, particularly in adults. 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. Imaging Studies Spondylolysis and spondylolisthesis is frequently identified with regular lumbar x-rays, especially the lateral side view x-rays.

The amount of forward translation spondylolisthesis is quantified by evaluating the percentage of slippage of one bone on another.

The slip angle is determined by how angulated the L5 bone is on S1.

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 acuteor 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.

Epidemiology

Laboratory Tests There are no laboratory tests used to diagnose spondylolysis or spondylolisthesis. A doctor performs this procedure by injecting radiopaque dye, under pressure, into the discs of the lumbar spine.

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.

My Account Spondylolisthesis Symptoms and Causes Video Importantly, spondylolysis only refers to the separation of the pars interarticularis a small bony arch in the back of the spine between the facet jointswhereas spondylolisthesis refers to anterior slippage of one vertebra over another in the front of the spine.

The test will often clarify where a nerve is actually being compressed - whether it is in the back, buttock, or leg.

An x-ray or CT scan is required to confirm the diagnosis, as well as to grade the severity of the condition. Nearly all patients are recommended for conservative treatment initially unless there is a severe neurologic deficit such as leg weakness and numbness.

Causes of Pars Defect

Physical therapy, chiropractic care and oral medications non-steroidal anti-inflammatory medications, pain medications, and muscle relaxant medications are frequently prescribed.

Patients who fail these conservative measures are usually candidates for surgical intervention.

Adult patients with significant stenosis narrowing of the spinal canal due to bone spurs generally require laminectomy and decompression, whereas children do not. The instrumentation fixes and holds the bones in place immediately, while the bone graft fuses mends the unstable spine bones together.

After the fusion surgery is performed, it takes approximately months for the fusion to "take" and the bones to solidly mend together. Prior to using metal instrumentation, patients were often required to be placed in body cast for 8 months to help the fusion mend.

Nowadays, most patients are recommended to wear only a small plastic brace or soft corset, if anything, for months after surgery to help the fusion solidify.A pars defect of the lumbar spine involves a part of a vertebra called the pars interarticularis.

Pars defect without listhesis

Roughly translated, that means "the part between two joints." A defect in the pars is a break in this portion of bone. This break leads to a separation of the upper, front . The pars interarticularis is the part of the vertebra between the superior and inferior facets (Figure 1).

The defect in the pars interarticularis may allow anterior (forward) displacement or slippage of the vertebra which is called spondylolisthesis (Figure 2).

Spondylolysis is a condition in which the there is a defect in a portion of the spine called the pars interarticularis (a small segment of bone joining the facet joints in the back of the spine).

With the condition of spondylolisthesis, the pars interarticularis defect can be on one side of the spine only (unilateral) or both sides (bilateral). Spondylolisthesis has several main causes. Doctors have developed a classification system to help talk about the different causes of spondylolisthesis.

Type II: Also called isthmic, this is the most common kind of spondylolisthesis. With type II spondylolisthesis, there's a problem with the pars. listhesis due to spondylolysis, many patients to make the diagnosis of a pars defect at an early stage.

I had very similiar issues with the pars defect (S1/L5) as well but had a 2 level fusion w/hw Nov While going up some stairs, on the third step without warning my left leg could not hold my weight and I just puddled on to the step, almost as if I meant to sit there.

I am waiting to talk with my Neuro Surgeon but in the meantime I am.
