What is a Disc?
The Spine is made up of the vertebrae (the bones making up the Spine), which have cartilage discs between them. The discs consist of a circle of connective tissue with a central gel-like core. This makes the spine flexible and at the same time acts as a protective buffer.
In the centre of this column of vertebrae and discs is the spinal canal, which contains the spinal cord and it continues as a bundle of nerve fibres called the cauda equina stretching down towards the sacrum. Between each vertebra, the spinal cord has nerve root connections to other parts of the body.
What is a Slipped Disc?
A slipped disc is when the soft part of the disc bulges through the circle of connective tissue. This prolapse may push on the spinal cord or on the nerve roots. However, it is worth noting that 20 per cent of the population have slipped discs without experiencing any noticeable symptoms.
The term ‘slipped disc’ does not really describe the process properly – the disc does not actually slip out of place, but bulges out towards the spinal cord.
Bulging disk, also known as a Contained Spinal Disorder, is a condition that occurs usually in spinal or lumbar region, lower back and in few cases witnessing with neck region. It commonly occurs as the human body ages and with the increase in age degeneration of inter vertebral disk occurs. Disks are soft material that engulfs the vertebrae of spinal chord and provides a cushioning support. When the disc moves out of its normal location or radius bulging disk occurs.
To understand the phenomenon of bulging disk, we have to understand the anatomy and physiology of intervertebral disc.
Spinal chord is encased by spine made up of intervertebral discs whose primary function is supporting the body weight. The repeated daily stress over time results in degeneration of the disc. Each vertebra of a spine contains intervertebral disc. The stress of every day movements is transferred to these discs. They act as shock absorbers to absorb any kind of impact and provide a cushioning support.
A healthy intervertebral disc contains a great amount of water in its center known as nucleus pulposus. This water content provides a spongy behavior to disc. An excessive pressure or injury can be harmful for the structure of outer ring of ligament covering nucleus pulposus. This ligament is better known as annulus.
What is the cause of a Slipped Disc?
Combine these factors with the effects from daily wear and tear, injury, incorrect lifting, or twisting and it is easy to understand why a disc may herniate. A herniation may develop suddenly or gradually over weeks or months.
A bulging disc though common in old ages, it is not necessary that everyone will experience the pain associated with it. Only when intervertebral disc extents towards spinal canal, pain arises.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_message style=”square” message_box_color=”mulled_wine”]
