Right Paracentral Disc Protrusion

A right paracentral disc protrusion refers to an intervertebral disc that is bulging outside of its normal circumference. As the name implies, the protrusion (or bulge) is occurring to the right of the disc’s center.

A disc protrusion means that one of the soft, oval-shaped discs located between the vertebrae has weakened and is pushing outward from its center. In cases of disc protrusions, however, the disc has not yet broken open and allowed its jelly-like center to leak out into the spinal column – a condition called herniated disc or ruptured disc.

Because a right paracentral disc protrusion does invade the surrounding space, there’s a chance that it may compresses other parts of the spine that are trying to function normally, such as the spinal nerves that are branching off the spinal cord.

A disc protrusion can be divided into two categories:

• Broad-based – a broad disc protrusion occurs when the protruding section of the disc covers 90-180 degrees of the total intervertebral disc circumference.
• Focal – when the protruding section of the disc covers less than 90 degrees of the total intervertebral disc circumference.

The term bulging disc may be used interchangeably with protruding disc, but a bulging disc is often classified as a disc bulge involving more than 180 degrees of the disc’s 360-degree circumference.

Right paracentral disc protrusion symptoms can take the following forms:

• Cervical disc protrusion – problems with mobility in neck, head, and shoulders; loss of feeling in hands and arms.
• Thoracic disc protrusion – pain that feels concentrated around the torso, sternum, rib cage, or diaphragm.
• Lumbar disc protrusion – numbness or tingling in the lower back, legs, and feet; radiating pain due to pressure on the sciatic nerve.
