Fracture Wrist - Hand

A fracture is another name for a break in the bone. There are 8 bones in the wrist joining the bones of the hand and arm, and these are held together by ligaments. The wrist joint is designed in such a way as to allow great flexibility and strength. This flexibility must be severely limited in order for your fracture to heal after a break, and often a plaster cast is required running from the hand to the elbow. As with most broken bones, once held immobile in a rigid plaster, the bone is capable of healing itself.

Wrist Sprain

Ligament connects bone to bone and keeps a joint steady. It is made from tough cord-like tissue, but has a weak blood supply and so finds it difficult to repair itself. They have half the holding power of steel and are tremendously flexible. The ligament is made up of fibres, like string twisted in to a rope. When you tear your ligament (see: Ligament Tear) you cut the rope. When you sprain it, you over-stretch or tear some of these strings or fibres.

Dupuytren’s Contracture

Connective Tissue is the name given to the substance that holds you together and gives your body its unique shape. It encloses your muscles, tendons, ligaments, bones and other organs. This fibrous tissue forms a web under your skin protecting and supporting your hand. In order for your hand to work at its best, all these structures need to be in perfect condition. In Dupuytren’s Contracture the fibrous tissue starts to thicken, and the skin and tendons begin to stick to each other so you can no longer open and close your fingers properly. Then it begins to contract, shortening the tendons and preventing your fingers from opening fully. Gradually you lose all movement in the fourth and fifth fingers and they become permanently closed. You will also notice a lump in your palm near the affected fingers that slowly develops into a cord-like band.

Carpal Tunnel Syndrome

Your nerves bring the information from your brain to your muscles that tells them when you want them to move. This information is brought to the hand via nerves like the median nerve. As the nerve leaves the wrist, it enters the hand through a tunnel (The Carpal Tunnel) where it is tightly protected. Too much pressure on this nerve over a time can damage it causing numbness and a feeling of pins and needles in the thumb and forefinger.

Rheumatoid Arthritis

Rheumatoid Arthritis is a condition that causes the body to attack itself. The lining of the joints are the first to be affected becoming hot and swollen, with the protective coverings of the joints and ligaments being worn down. Usually, a number of joints are involved at the same time; most likely to suffer are the hands, wrists, feet, knees and elbows. It can also affect other parts of the body, including the heart. Nobody is sure what causes the disease, but it often comes in phases that can ease up after a few months or years.
