Tenosynovitis

Tendons attach muscle to bone and are the focus for the “pull” of the muscle. They are encased in sheaths that are naturally lubricated so that they slide easily when you use your muscles. In Tenosynovitis there is a malfunction of the lubricating system between the tendons and their sheath in the affected joints, causing them to “grate” and they then become irritated and inflamed. The sheath then becomes thickened and the tendons can no longer glide smoothly. This will sometimes cause the finger to click as you bend or straighten it. This is an over-use injury caused by repetitively using the fingers when they are under too much stress. It may also be caused by infection. It is a common condition among typists.

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.

Skier’s Thumb

This painful condition is caused by over-stretching the thumb. As the thumb is forced backwards toward the wrist, the ligament over-stretches and causes pain. Ligament connects bone to bone and keeps joints stable. If it is over stretched the joint becomes loose. The repair to a damaged ligament is always slow because of poor blood supply to the area. Other tissue like scar tissue grows much more quickly and your body will use this to replace the damaged part of the ligament. Scar tissue is not nearly as efficient as the original ligament. Without effective therapy the thumb may never fully recover.

Dislocated Finger

This a common minor injury, frequent in contact sports like football, rugby and basketball. If your hand is caught awkwardly in a tackle, or struck by a ball your finger may slip slightly out of alignment on contact. Usually this happens at the joint above the knuckle. It will be very sore and you will be unable to bend it properly. The amount of swelling will be small depending on how recently it has happened and in the early stages bruising will not be seen.

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.

Ulnar Neuritis

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 outside of the hand (little finger side) via the ulnar nerve. It travels under your elbow to the ring and little finger and is sometimes called the “funny bone”. Too much pressure on this nerve over a time can damage it causing numbness, a burning feeling and a tingling sensation in the hand and fingers.

Trigger Finger

Tendons attach muscle to bone and are the focus for the “pull” of the muscle. Some are encased in sheaths that are naturally lubricated so that they slide easily when you use your muscles. In Trigger finger there is a malfunction of the lubricating system between the tendons and their sheath in the affected finger or thumb, causing them to “grate” and they then become irritated and inflamed. The sheath then becomes thickened and the tendons can no longer glide smoothly. This will sometimes cause the finger to click as you bend or straighten it. This is an over-use injury caused by repetitively using the thumb when it is under too much stress.

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.

Mallet Finger

This injury happens when a hard blow to your finger tears the tendon away from the bone. Sometimes a small fragment of the bone will break off too. This means that you will not be able to straighten the finger joint nearest your nail without using your other hand. The joint will straighten if you use your other hand but not on its own. Unless the injury is treated properly, it will remain permanently bent and could be prone to arthritis in later life.

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.
