Exploring Annular Fissure: Causes, Symptoms, and Treatment

An annular fissure is caused by age-related changes to the spine, which often do not cause symptoms but can cause back pain. Can understanding the causes help individuals manage lower back pain and help healthcare providers develop an effective treatment program?

Annular Fissure

An annular fissure is a discogenic condition that affects the spine and can cause lower back pain. Also called an annular tear, it’s usually a wear-and-tear condition that happens over time rather than a condition caused by trauma. It usually happens when the fibers that make up the annulus or the tough outer covering of the intervertebral disc break or separate. To manage it, healthcare providers may recommend:

• Making lifestyle changes.
• Staying aware of how you go about daily activities and take steps to make adjustments, such as being mindful of unhealthy posture.
• Start doing exercises that help make the back stronger.
• Medical care if pain and other symptoms need to be managed.

Symptoms

Lower back pain may be a sign of an annular fissure, or there may be no symptoms. Symptoms can include:

• Pain
• Weakness
• Numbness
• Electrical sensations travel down one leg or arm if a cervical/neck tear is present.
• Numbness and weakness may be caused by the nerves getting irritated or compressed near an annular tear. (Stadnik, T. W. et al., 1998)
• These symptoms can also be similar to a herniated disc, which can be a complication of an annular fissure.
• However, studies have shown that annular tears and herniated discs often go unnoticed because they have few obvious symptoms. (Jarvik, J. G. et al., 2005)

Annulus Function

The annulus comprises several layers of tough fibers/fibrocartilage that surround, contain, and protect the soft, liquid nucleus inside the disc. The layers of the annulus fibrosus crisscross to provide support. The nucleus is a shock absorber cushions the body’s weight on the spinal joints when sitting, standing, or moving. Its strength also allows the disc to buffer the jolts and jars it experiences. It also helps maintain the integrity of the intervertebral joint by supporting the space between the two vertebrae. When an annular fissure occurs, the fibers separate or tear off from insertion on the nearby spinal bone. A fissure can also be a break in the fibers of one or more layers. (Jarvik, J. G. et al., 2005)

Causes

An annular tear is not the standard term medical professionals use to describe or diagnose a fissure because the word tear suggests that trauma has led to the separation or break in the fibers. While an injury can cause an annular fissure, it’s usually caused by long-term wear and tear. (Guterl, C. C. et al., 2013) The tears are typically caused by age-related degenerative changes in the disc, which can also lead to degeneration in other areas of the spine. Wear and tear are caused by annular fissures due to an individual’s daily living habits, such as sitting, standing, walking, climbing stairs, and performing other routine movements.

Treatment

While a large annular fissure is not likely to improve without treatment, a small one could heal independently. However, once an area has torn, it becomes more likely to continue tearing. (Virginia Spine Institute, N.D.) Conservative treatment is usually enough to control pain and symptoms. Physical therapy and anti-inflammatory medication are the first line of treatment. (Cheng, J. et al., 2019) Medication can be over-the-counter or prescription. Physical therapy treatment includes exercises, traction, and other therapies. If these do not help with the symptoms, the provider may suggest a steroid injection to reduce inflammation and pain. It can take three to six months to recover from degenerative disc problems if doing a standard treatment plan that includes rest, low-impact therapy exercises, and anti-inflammatory treatments. (Cheng, J. et al., 2019)

In severe cases, surgery may be recommended, including disc replacement surgery. An annular tear is not a reason to have disc replacement surgery alone; it is only when there are degenerative changes in the vertebral disc that surgery might be necessary. (Yue, J. J. et al., 2012)

Improving Body Alignment

Not paying attention and being aware of how the body performs everyday activities can, over time, set the stage for an annular fissure and other musculoskeletal injuries. However, fixing daily movement and posture habits to prevent injuries can be done through simple adjustments. For example, strengthening the core and back muscles can reduce pressure on the spine and help prevent injuries. (Camp, C. L. et al., 2016) The idea is to improve joint and overall body alignment. Activities can include:

• Strength training
• Walking
• Pilates classes
• Yoga
• Tai chi
• Somatic exercises

These activities help with muscle balance and joint alignment, which are recommended prevention strategies that physical therapists use when working with individuals who need help with spinal problems.

Visiting a chiropractic and physical therapy team can help treat injuries and chronic pain syndromes, relieve pain, resolve musculoskeletal issues, and prevent future symptoms. Injury Medical Chiropractic and Functional Medicine Clinic works with primary healthcare providers and specialists to develop a personalized care program for each patient through an integrated approach to treating injuries, improving flexibility, mobility, and agility to help return to normal and optimal function. If other treatments are needed, Dr. Jimenez has teamed up with top surgeons, clinical specialists, medical researchers, and rehabilitation providers to provide the most effective treatments.
