Surgical procedure for relieving pressure usually on a nerve or the spinal cord.
The process of change, usually with age, in bone or soft tissue. Sometimes referred to as ‘wear and tear’.
Degenerative Disc Disease
The discs undergo a process of change from a supple, flexible structure that allows movement and acts as a cushion, to a stiff and rigid one that restricts the amount of movement and is a less effective cushion. This process can start as early as the 20th to 30th year of life and by the 60th year it would be a universal finding on x-ray examination. Many people will not have any symptoms.

The outer-most membrane surrounding the fluid that protects the spinal cord and brain.
Unpleasant abnormal sensations, whether spontaneous or evoked.
Epidurals are given for the relief of leg pain. A cocktail of drugs containing a corticosteriod and a local anaesthetic is injected into the epidural space, between the bone and the membrane that encloses the spinal cord.
As one vertebra sits on another the top of one and the bottom of the other meet at two places referred to as the facet joints. They are synovial joints, that is they are encapsulated and produce a lubricating fluid.
(Latin, fenestra = a window). Surgical procedure for accessing spinal nerves or a disc prolapse.
This is the gap between the vertebrae that holds nerve roots as they emerge from the spinal cord to the left and right.

The convex curve of the thoracic spine. It can be over exaggerated in such diseases as Osteoporosis or Scheuermann’s disease.
This is an operation to remove part of the bony arch at the back of a vertebra. This is done to gain access to the nerves in the foramen and allow them more space.
The concave curve found in the cervical and lumbar regions of the spine. Can be a deformity if it is excessive.
These are bands of fibrous tissue that bind a joint and control its range of movement.
The area of the spine between the thoracic vertebrae and the sacrum.
An imprecise term for low back pain.
Magnetic Resonance Imaging involves a highly technical scanner that uses magnetic fields and computer technology to generate images of the internal anatomy of the body, including discs and nerve roots. It is a painless procedure, although like CT scans, people with claustrophobia may find it difficult. Most scanners have a panic button and radiologists will talk you through the process. Some units may have open scanners. A contrast medium (Gadolinium) can be used intravenously to gain clarity of image, especially with those who have already undergone back surgery
A water-soluble, radio-opaque dye is injected into the cerebro-spinal fluid. This allows nerve tissue to be viewed on x-ray and enables a doctor to trace any nerve entrapment. This is an invasive procedure that many people report to be unpleasant!
The start of the nerve as it leaves the spinal cord or cauda equina and passes through the left and right foramen to serve an area of the body.
Pain in the distribution of a nerve or nerves
Neuropathic pain is pain initiated or caused by a primary lesion or dysfunction in the peripheral or central nervous system. For example pain following shingles, or an amputation, or spinal cord trauma. Pain that occurs in diabetics or in patients with multiple sclerosis. Can also be neuropathic.

Opioids are a group of medicines that come from the opium poppy or are closely chemically related to it. Opioids have been used for many years for managing pain. There are many different medicines in this group and differ in the ways that they can be used and in their strengths. Some can be taken by mouth, and others are used by applying a patch to the skin. Opioids have traditionally been classified as week or strong.

Sometimes referred to as Spinal Osteochondritis. This is a developmental abnormality in the intervertebral discs and vertebral bodies causing them to become wedge-shaped. This can cause an increase in the kvphotic (see kyphosis) curve and predispose the person to premature wear and tear. Exercise and attention to posture and lifestyle are important to prevent pain and deformity
A sideways curvature of the spine, which can be caused by a congenital deformity or a temporary reaction caused by muscle spasm.
Strictly speaking it is pain along the length of the sciatic nerve that is down the back of the thigh, through the calf and into the foot. It is sometimes used more loosely to describe any leg symptoms.

A condition where one vertebra slips out of alignment with another. Most common is the fourth over the fifth lumbar vertebra or the fifth over the sacrum. The causes can be congenital or due to structural defects, degenerative changes and injury. Some people have it without symptoms, but others have major pain and nerve-related symptoms. Called retrolisthesis if the slippage is backwards.
