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

Sudden Loads On Lumbar Discs

In experiments on lumbar spines from cadavers the commonest way a disc will fail is if it is placed in significant bending and compressed quickly is to form a prolapse at the rear of the disc. Prolapse occurred most easily in discs which had not degenerated but were between forty and fifty years old. It was not possible to make a very degenerated disc prolapse. The angle of bend or the compressive forces do not need to be excessive as if one of them is over the normal limits it can generate a prolapse. Prolapses mirrored what people say as they occurred with an audible popping sound and occurred suddenly.

Typically a complete split appeared in the rear part of the disc wall and through this fissure the internal nuclear material prolapsed. The prolapse either occurred at one corner of the back of the disc (a common finding in people with disc problems) or more centrally where the nearby ligament prevented it from moving out further. Disc prolapse occurs mostly in discs with some weakening of the disc wall fibres yet a reasonably good nucleus which can respond to the forces by generating high pressures. Degenerated discs did not prolapse on testing.

Examination of the Injured Wrist

Initial examination of a person with a wrist injury involves visual inspection of the wrist compare to the other one, as some people have relatively abnormal wrist structure and limited movements. Bruising and swelling may be present as may be one of the typical deformities due to fractures of the distal forearm bones. Palpation of the bony anatomy systematically allows a closer determination of the location of any acute injury such as a fracture. The typical deformity of a Colles fracture is the so-called .dinner fork. deformity where the end of the wrist is angled upwards and the fingers form the prongs of the fork.

In the Smith fracture where the end of the wrist is pushed downwards the deformity is known as a .garden spade. deformity. It is important to examine the remainder of the upper limb including the shoulder, elbow and wrist to exclude other injuries or fractures, with the patient's report of where they have pain a very useful guide. The patency of the arterial systems in the forearm and arm are also assessed as vascular damage can occur from fracture fragments. The three nerves which pass down the arm and supply the feeling and muscles of the hand should also assessed for damage.
