Degenerative Disc Disease
Degenerative disc disease refers to the process of degeneration of an intervertebral disc.
Your intervertebral discs are the fluid filled sacks, which lie in between each vertebrae and act as the shock absorbers for your spine. They are made up of two parts: Inner nucleus pulposes and outer annulus fibrosis.
The annulus fibrosis is made up of dense fibrocartilage rings and encases the nucleus. The outer ring of the annulus is innervated, meaning there is a nerve supply and can be painful when damaged. The nucleus is the inner part of the disc, which is jelly like in consistence. It changes shape as it adapts to the different loads placed on the disc.
A healthy disc is fluid filled. Breakdown of a disc begins when it becomes dehydrated or loses part of its fluid content. This can initiate a cascade of events, which leads to eventual breakdown, and degeneration of the spinal complex.
Disc degeneration can lead to:
- Facet joint Dysfunction
- Herniated discs
- Spinal Instability
- Bony spur growth
- Nerve impingement
Disc degeneration is a normal part of the ageing process. It is important to note that you can have disc breakdown with the absence of pain. The good news is there is lots you can do yourself to rehydrate your discs and slow the degenerative process down.
What is the cause?
Disc degeneration is a normal part of the ageing process however there are certain things that can accelerate the degenerative process.
Risk factors include:
- Sedentary lifestyle
- Poor core stability
- Repetitive heavy manual labor
Signs & Symptoms
- Persistent pain at the bottom of the spine
- Pain when sitting
- Pain going from sitting to standing
What can we do about it?
Your physiotherapist will first identify the abnormalities in movement of your spine and will then determine the cause of this.
Core stability training will form a large part of your rehabilitation and prevention of further episodes of back pain.
Movement is the key to rehydrating discs and encouraging repair. Your physiotherapist will provide you with an individualised exercise program to help enable the healing process.
