Intervertebral Disc

The ?brous disc that acts as a cushion between the bony vertebrae (see SPINAL COLUMN), enabling them to rotate and bend one on another. The disc tends to degenerate with age and may get ruptured and displaced – prolapsed or slipped disc – as a result of sudden strenuous action. Prolapsed disc occurs mainly in the lower back; it is more common in men than in women, and in the 30–40 age group.... intervertebral disc

Optic Disc

Otherwise known as the blind spot of the EYE, the disc is the beginning of the optic nerve – the point where nerve ?bres from the retina’s rods and cones (the light- and colour-sensitive cells) leave the eyeball.... optic disc

Disc

An anatomical term describing a rounded ?attened structure. Examples are the cartilagenous disc positioned between two vertebrae (see SPINAL COLUMN) and the optic disc (see EYE).... disc

Prolapsed Intervertebral Disc

The SPINAL COLUMN is built up of a series of bones, known as vertebrae, placed one upon the other. Between these vertebrae lies a series of thick discs of ?bro-cartilage known as intervertebral discs. Each disc consists of an outer portion known as the anulus ?brosus, and an inner core known as the nucleus pulposus. The function of these discs is to give ?exibility and resiliency to the spinal column and to act as bu?ers against undue jarring. In other words, they are most e?cient shock-absorbers. They may, however, PROLAPSE, or protrude, between the two adjacent vertebrae. If this should happen they press on the neighbouring spinal nerve and cause pain. As the most common sites of protrusion are between the last two lumbar vertebrae and between the last lumbar vertebra and the sacrum, this means that the pain occurs in the back, causing LUMBAGO, or down the course of the sciatic nerve causing SCIATICA. The prolapse is most likely to occur in middle age, which suggests that it may be associated with degeneration of the disc involved, but it can occur in early adult life as well. It usually occurs when the individual is performing some form of exercise which involves bending or twisting, as in gardening. The onset of pain may be acute and sudden, or gradual and more chronic in intensity. (See also INTERVERTEBRAL DISC.)

Treatment varies, depending (amongst other things) on the severity of the condition. In the acute phase, rest in bed is advisable, along with ANALGESICS. Later, exercise and physiotherapy are helpful, and in some cases manipulation of the spine brings relief by allowing the herniated, or prolapsed, disc to slip back into position. The injection of a local anaesthetic into the spine (epidural ANAESTHESIA) is yet another measure that often helps the more chronic cases. If those measures fail, surgery to remove the prolapsed disc may be necessary, but the patient’s condition should be carefully reviewed before surgery is considered since success is not certain. An alternative form of treatment is the injection into the disc of chymopapain, an ENZYME obtained from the paw-paw, which dissolves the disc.... prolapsed intervertebral disc

Cupping

An ancient form of treatment, still used in folk healing in some countries, which draws blood to the surface by applying a small heated vessel to the skin.

Disc, Intervertebral

A flat, circular, plate-like structure containing cartilage that lines the joints between adjacent vertebrae (bones) in the spine. Each intervertebral disc is composed of a fibrous outer layer and a soft gelatinous core. It acts as a shock absorber to cushion the vertebrae during movements of the spine. With increasing age, intervertebral discs become less supple and more susceptible to damage from injury.

Disc Prolapse

A common disorder of the spine, in which an intervertebral disc ruptures and part of its pulpy core protrudes. It causes painful and at times disabling pressure on a nerve root or, less commonly, on the spinal cord. The lower back is most commonly affected. A prolapsed disc may sometimes be caused by a sudden strenuous action, but it usually develops gradually as a result of degeneration of the discs with age. If the sciatic nerve root is compressed, it causes sciatica, which may be accompanied by numbness and tingling, and, eventually, weakness in the muscles of the leg. A prolapsed disc in the neck causes neck pain and weakness in the arm and hand.

Symptoms improve with time and analgesic drugs. However, in severe cases, surgical techniques, such as decompression of the spinal canal or removal of the protruding material and repair of the disc, may be necessary.... disc prolapse

Embryonic Disc

the early embryo before the formation of *somites. It is a flat disc of tissue bounded dorsally by the amniotic cavity and ventrally by the yolk sac.
