Spondylolisthesis

Spondylolisthesis



What is it?


This condition occurs when two vertebrae slip or slide over one another to produce the abnormal positioning of two or more vertebrae in relation to each other along the spinal column.


Spondylolisthesis is categorized into different types, each of which has five grades of severity.

What causes it?


This condition can be congenital, (caused by a birth defect); degenerative (related to aging), Isthmic, (having a spondyloltic defect); traumatic (most commonly fractures); or pathologic (in this case, a disease of the bone).


Regardless of the cause, there is a good chance the condition will get worse if you do nothing. One underlying factor in spondylolisthesis is having your core muscles out of balance with each other. Those imbalances can cause what are called "pelvic dysfunctions." Unless these dysfunctions are addressed, it will be hard for you to find relief. Even worse, these pelvic dysfunctions will put abnormal pressure in the spine and prevent the spine from stabilizing.


What are the symptoms?


The severity and the type of symptoms associated with spondylolisthesis depend on the grade of the condition. Grades range from low to high (1 to 5), with each grade representing the percentage of vertebrae slippage. For example, Grade 1 indicates slippage of less than 25 percent, while Grade 5 represents 100 percent slippage—where the top vertebra completely falls off the supporting bone below it.


Common complaints range from local pain to radiating pain. You may experience leg pain or pain in the buttock, or you may feel a more generalized numbness, tingling, or weakness. It all depends on the amount of contact with the nerves.


An inability to control urine or stool, or to initiate a urine stream, could indicate that the slippage may be pushing on the spinal cord itself. This would be considered a medical emergency, so anyone with these symptoms should seek immediate medical attention.

What are the most common treatments?


Cortisone injections straight into the joint, non-steroidal anti-inflammatory drugs (NSAIDs), hot packs, ultrasound, electrical stimulation, and therapeutic exercises are commonly employed.

If deemed necessary, a surgical procedure can eliminate any contact a vertebra has with a nerve and stabilize the vertebrae to prevent further slippage.

Which treatments work best?


Once the slippage has happened or you have been diagnosed with a progressive form of this condition, it is recommended that you seek professional help from a qualified expert in spondylolisthesis who can initiate the most comprehensive and conservative approach possible.

The principles of Muscle Balance Therapy can help you strategically assess your individual muscle imbalances and develop a very targeted corrective program to meet your specific needs.



Sciatica can also be caused by Isthmic spondylolisthesis, yet is much less common. Spondylolisthesis occurs when one vertebrae slips forward and places pressure on the adjacent vertebrae. This condition will produce both a gradual deterioration of the vertebrae in the lower spine and can also cause a narrowing of the spinal canal.

If abnormal motion allows this vertebrae to move back and forth nerves in the spinal canal may be affected causing pain, numbness, tingling or weakness in the legs. Many individuals who have this condition may not have symptoms while others may experience long term back pain and or sciatica.

Spondylolisthesis is most common in the lower spine. The most common cause is degenerative disease (like arthritis) and the slip usually occurs between the fourth and fifth lumbar vertebrae where there is the most curvature in the spine. Muscle imbalances play a major role in two ways:
1. Degenerative diseases like arthritis are much more common in areas of the body where there is uneven pressure and wear and tear.

2. Muscle imbalances increase the amount of curvature in the lower spine making this condition much more likely to come about.

Other causes of spondylolisthesis include stress fractures (which are often caused by repetitive hyper-extension of the back, commonly seen in gymnasts), and traumatic fractures.
Spondylolisthesis may also occasionally be associated with bone diseases. As with the other three conditions, muscle imbalances have a lot to do with spondylolisthesis.
