The inter-vertebral discs are protective cushion-like shock-absorbing pads between the two bones of the spine called vertebrae. These discs are soft gel filled pads bounded by few layers of membrane called lamella. These discs do not actually “slip,” they may split or rupture (Slipped Disc is a misnomer). Following this rupture the gel escape into the surrounding tissue. The leaking jellylike substance can produce pressure on the spinal cord or on a single nerve root and cause pain either around the damaged disc or anywhere along the area controlled by that nerve. This condition is also known as a herniated disc, ruptured disc, prolapsed disc, or, more commonly, slip disc or slipped disc.

2.Sciatica is a frequently used term both by doctors and by patients. It is a symptom and not a disease. Sciatica is defined as any pain that is starting in the low back and is going towards the legs. Sciatica is a non-specific term like fever.
3. Slipped disc is one of the most common cause of sciatica. Apart from conservative therapy all other forms of treatment aim at decompressing the nerve roots. These can be done by taking the disc out by surgery or by decompressing the foramen and disc by different interventions.
