Physiotherapists in Hove treat many different conditions including the issues profiled below.

Disc Prolapses

In a disc prolapse the internal material of the disc becomes displaced in relation to the outer annulus. The annular rings should be around the disc and the water retaining nucleus at the centre of the disc should remain there. In one kind of protrusion the disc bulges the annular fibres outwards but the nuclear material remains inside the disc. If the annular fibres rupture right through their thickness then part of the nucleus can extrude outside the confines of the disc but it still remains in contact with the rest of the nucleus inside the disc.

A third type of disc prolapse can occur where the disc tissue is extruded from the disc but then is separated from the nucleus and exists as an independent fragment outside the disc walls. Disc prolapses or herniations do not seem to be well connected with age or changes of degeneration of the discs even though it is again most common at lower lumbar levels which are subject to both degeneration and stresses more than other spinal regions. Even though disc prolapses are often called .slipped discs., the disc cannot slip as it is tightly bound to the vertebrae above and below.

Common Causes of Disc Prolapse

Spinal surgeons know that most disc herniations they are required to operate on are mostly made up of nucleus pulposus and rarely consist of much of the annulus fibrosis, which never occurs alone in a prolapse. Typical actions which risk prolapse are lifting and carrying, imposing flexion, side bending and compression loads on the lumbar spine at the same time. Combinations of these forces are what make a prolapse more likely, such as falling on the bottom whilst the legs are straight out in front, combining compression and bending. Other combinations could include tripping and so bending forward whilst carrying, reaching forward to catch a heavy object or lifting something heavy after a period when the spine has been in flexion.

If the upper body is pulled forwards suddenly and a force applied this is the most risky posture as the back muscles are contracting most strongly to resist the forward movement at that time and so increasing the compression through the spine. Due to fact that the discs are tighter and more swollen with water in the morning, it seems that disc prolapse may be more likely to occur at this time. Repeated bending in heavy jobs could also cause prolapse with time.
