Spondylolisthesis – Isthmic

Spondylolisthesis is a condition of spinal instability, in which one vertebra slips forward over the vertebra below; isthmic spondylolisthesis, the most common form, is caused by a bony defect (or fracture) in an area of the pars interarticularis, located in the roof (laminae) of the vertebral structure. Treatment options for isthmic spondylolisthesis may be non-surgical for lesser cases, and the more severe cases may require surgery including spinal fusion.

Symptoms of Isthmic Spondylolithesis, Most Commonly Affecting the 4th and 5th Lumbar Vertebrae (L4 and L5) and the 1st Sacral Vertebra (S1)

Symptoms of isthmic spondylolisthesis, which occurs in approximately 4% of the population, may include the following:

  • Pain in the low back, thighs, and/or legs (especially after exercise) that radiates into the buttocks
  • Muscle spasms
  • Leg pain or weakness
  • Tight hamstring muscles
  • Irregular gait

Some people are symptom-free and only discover the disorder when seeing a doctor for another health problem. In severe cases, the condition may cause swayback and a protruding abdomen, a shortened torso, and a waddling gait.

What Causes Isthmic Spondylolisthesis?

Isthmic spondylolisthesis can be the result of a genetic failure of bone formation in the spinal vertebrae; usually physical stresses to the spine then break down the weak or insufficiently formed vertebral components. Repeated heavy lifting, stooping, or twisting can cause small fractures to occur in the vertebral structure and lead to the slippage of one vertebra over another. Weightlifters, football players, and gymnasts often suffer from this disorder due to the considerable stress placed on their spines.

While it may not be possible to prevent all spine problems, there are things you can do to help keep your spine healthy. The most important prevention method is to avoid or limit those work or recreational activities that cause considerable stress to your spine. Losing weight, starting a regular exercise regimen, not smoking, and learning proper body mechanics can all help reduce the risk of further back problems.

Diagnosis of Isthmic Spondylolisthesis

To make an accurate diagnosis, your physician will conduct a careful and rigorous diagnostic process, including:

  • Medical history. The physician will talk to you about your symptoms, how severe they are, and what treatments you have already tried.
  • Physical examination. You will be carefully examined for limitations of movement, problems with balance, and pain. During this exam, the doctor will also look for loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of neurological damage.
  • Diagnostic tests. Generally, doctors start with plain x-rays, which allow us to rule out other problems such as tumors and infections. We may also use a CT scan or MRI to confirm the diagnosis. In some patients we may need a myelogram, a test that uses a liquid dye injected into the spinal column to show the degree of nerve compression and slippage between involved vertebrae.

Grading Slippage for an Isthmic Spondylolisthesis

There are several methods used to “grade” the degree of slippage ranging from mild to most severe. Your surgeon will discuss with you the extent of your spondylolisthesis and how the severity indicates the type of treatment that is needed.

In general, most physicians use the Meyerding Grading System for classifying slips. This is a relatively easy to understand system. Slips are graded on the basis of the percentage that one vertebral body has slipped forward over the vertebral body below. Thus a Grade I slip indicates that 1-24% of the vertebral body has slipped forward over the body below. Grade II indicates a 25-49% slip, Grade III indicates a 50-74% slip, and Grade IV indicates a 75%-99% slip. If the body completely slips off the body below it is classified as a Grade V slip, known as spondyloptosis.

Your physician will consider the degree of slip, and such factors as intractable pain and neurological symptoms, when deciding on the most suitable treatment. As a general guideline, the more severe slips (especially Grades III and above) are most likely to require surgical intervention.

Non-Operative Treatment of Isthmic Spondylolisthesis

For most cases of isthmic spondylolisthesis (especially Grades I and II), treatment consists of temporary bed rest, restriction of the activities that caused the onset of symptoms, pain/anti-inflammatory medications, steroid-anesthetic injections, physical therapy and/or spinal bracing.

Surgical Treatment of Isthmic Spondylolisthesis

The most common surgical procedure used by Dr. Antonacci for treatment, is one he also pioneered.   It is the muscle sparing approach to interbody fusion (FLIF).   Unlike FLIF, traditional approaches detach back muscle  such as when a laminectomy is performed in combination with fusion.    Here, the spinal canal is widened by removing or trimming the laminae (roof) of the vertebrae. This is done to create more space for the nerves and relieve pressure on the spinal cord. The surgeon may also need to fuse vertebrae together. If fusion is done, various devices (like screws or interbody cages) may be implanted to enhance fusion and support the unstable spine.  Dr. Antonacci’s’ approach which is muscle sparing, has less blood loss and faster recovery times, without compromising in anyway, visualization or nerve decompression (see FAQ).
