Herniated Discs, Bulging Discs, Extruded Discs Oh My!!!
What are spinal discs?
Spinal discs are a critically important part of your spinal column. Along with the vertebrae, also called the spinal bones, they perform many functions. The discs provide shock absorption, protecting the spinal cord and ensuring flexibility of the spine. They also perform other functions. The spinal discs are essentially ligaments (structures connecting bones) that attach to the top and bottom of each vertebra. They are thick, ligament-like outer rings, also known as annuli fibrosis. Because they are arranged in an alternating pattern with the vertebrae, annuli fibrosis allow flexibility while preventing the vertebrae from moving too much and causing injury. Inside a single annulus fibrosis is a jelly-like substance called the nucleus pulposis. It contains some proteins, but is primarily made up of water. The nucleus provides more shock absorption than does the annulus, and it also acts as a fulcrum to direct the type of movement through which each vertebra travels.
What are the most common disc problems?
- A disc “bulge” results from slight tears in the outermost fibers of an annulus fibrosis. These small tears can be painful for a short time.
- A disc protrusion/extrusion, also called “herniation,” is a more significant injury. It results from a complete or significant tear of the fibers of an annulus-when some of the nucleus leaks through. A herniation can also be painful and may even cause nerve compression. In the most severe cases, the spinal cord can become compressed.
- The most common disc problem suffered by adults is degenerative disc disease. This occurs when the nucleus loses water and small tears develop in it. The body then forms osteophytes (bone spurs), along the edges of the vertebra and the disc space narrows. We used to believe that this was a function of “wear and tear” as we aged. The most recent evidence shows that, most often, there is a hereditary link to the development of degenerative disc disease. Degenerative disc disease can also be caused by trauma/injury.
Common signs of disc problems include, but are not limited to:
- Back or neck pain
- Leg or arm pain
- Tenderness of the spine and spinal muscles
- How are disc problems diagnosed?
Disc problems are most often diagnosed with the use of a thorough history and physical examination, including examination of your nervous and musculoskeletal systems. Your doctor will most likely move your back and arms and legs into various positions while applying pressure to your joints. Plain film x-rays are helpful in only some forms of disc problems. Magnetic resonance imaging (MRI) has become the mainstay for the diagnosis of disc problems, as it images the discs quite nicely. Your doctor may order an MRI if he or she feels it would be helpful in diagnosing a disc problem and determining the proper course of care for you. Most often, however, this is not necessary.
How are disc problems treated?
Luckily, in most circumstances, disc problems are easily treated with conservative interventions. Early in the course of an acute injury, your doctor of chiropractic will very likely set a goal of pain control, using several different physical modalities to reach it. Both ice and heat have shown effectiveness in managing the pain of acute low-back injury. Your doctor of chiropractic will help you determine which is most effective for you. In addition, getting you back on your feet and moving as quickly as is safely possible is critical. Typically, the less time you spend in bed, the better off you are in terms of long-term results. You’ll also need to learn not to be afraid to move. If you “baby” your back, in most cases, the long-term results will be worse.
Chiropractic spinal manipulation has also been demonstrated to be a safe and effective tool in the management of disc problems. Manipulation is especially effective when combined with therapeutic exercise. In most circumstances, spine surgery and injections are not necessary in the management of disc problems- and they often cause more problems than they’re worth. Your doctor of chiropractic will discuss all available treatment options with you and help you decide on the best course of action.
Can disc problems be prevented?
While regular exercise will help strengthen your back, research has demonstrated that staying fit and using proper body mechanics alone will not prevent injury. The National Institute for Occupational Safety and Health (NIOSH) recommends that individuals do not lift more than 50 lbs. Further, activities that require awkward or prolonged postures and repetitive activities place individuals at high risk for musculoskeletal disorders and disc problems regardless of body mechanics and fitness level. Your doctor of chiropractic can conduct an ergonomic assessment of your work and home activities to help you prevent injury.
It is also critically important to have “spinal awareness.” Make a conscious effort, for example, to be aware of what posture you are maintaining when you sit, stand, lie down, work, and exercise. Lift objects with proper posture, including bending your knees, keeping the object close to your body, keeping your back straight and lifting with your legs. Never lift an object by bending over and twisting. You’ll only invite a back injury.
If you experience any of the following, seek immediate medical care for a spine problem:
- Loss of bowel or bladder control
- Inability to urinate and/or defecate
- Acute loss of feeling in both buttocks and/or both arms
- Inability to walk or use your arms (often from severe acute weakness)
- Fever along with your back pain
