Definition

Intervertebral disc is a disc-shaped fibrocartilage structure connecting two vertebrae, allowing spine movement. It is composed of elastic fibrous rings and semi-liquid nucleus pulposus, which can cushion the pressure and impact on the spine. When the annulus fibrosus wears out, the nucleus pulposus protrudes outward through the fissure which causes prolapsed disc, and may squeeze directly to the related nerve and cause limb pain.

Causes



The nucleus pulposus contains more than 80% of water. When the fibrous annulus gradually has cracks due to degeneration or external impacts, the water content continues to decrease. The elasticity and cushioning capacity also decrease. In addition, prolonged bending of the spine or carrying heavy objects while bending down, or a sudden twist or high impact injury due to a car accident are factors causing the disc to prone to prolapse.

 

 

Risk Factors

Poor posture or prolonged back flexion might increase the pressure of the intervertebral disc. Intervertebral disc injuries mostly occur in people who usually sit or require heavy labor to carry heavy objects, such as office workers, drivers, and porters.

 

 

Common Symptoms
  • Lower back pain and back stiffness
  • Difficult to change posture while staying in the same posture for a long time
  • If the nerve is compressed at the same time, it can cause pain or numbness in the buttock and lower limbs
  •  In severe cases, it can cause upper or lower limbs weakness

 

 

Management

Although acute or severe pain requires adequate rest, this does not mean that total bed resting is the fastest way to recover.

 

Electrophysical therapy, hydrotherapy, acupuncture, joint mobilization, and traction can help reduce pain and its radiation to the extremities. Depending on one's condition, Mckenzie spinal therapy can effectively differentiate and treat the cause of this disease. It can make prolapsed intervertebral discs easier to recover or return to their original alignment. We should pay more attention to maintain a correct posture in daily life, and do not sit for more than an hour without stretching. If necessary, a backrest cushion can be added to support the back curvature. When the pain is relieved, targeted deep core muscle strength, endurance training, and stretching can improve the chance and speed of recovery.

Preventive Measures

In addition to paying attention to the daily posture, if your work nature needs a lot of manual lifting procedures, you should pay attention to the correct lifting posture to reduce the chance of back injuries. Moreover, a regular core muscle exercise regime can greatly reduce spinal stress.
