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.

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.

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.

Groin Strain

Tendon attaches muscle to bone and is the focus for the “pull” of the muscle. What happens in Groin Strain is that the muscle pulls part of the tendon away from the bone or away from the belly of the muscle and the attachment point (or focus) becomes frayed and sore. There is extra pressure on these point when you over-stretch your leg outwards, or it can be pressured by kicking a ball and those repeated jarring effects can cause damage. While the tendons themselves are enormously strong (half the tensile strength of steel), the attachment is usually weaker and first to give.

Torn Ligaments

The 3 bones of the knee are held together by 4 main ligaments, 2 at the front, deep in the knee, which run from top to bottom, diagonally and cross each other. Since they cross, they are referred to as cruciate ligaments. The other 2 ligaments are located, one at either side. The knee is normally a very strong and stable joint, because of the strength of these ligaments. Tearing or severing any one of these ligaments, aside from being extremely painful, is very damaging to the stability of the joint and consequently a career threatening injury. Torn ligaments will not heal themselves, they need to be surgically repaired. Usually ligaments torn in the centre will be sewn together, and ligaments torn from the bone will be stapled back on to it.

Ligament Sprain

Ligament connects bone to bone and keeps a joint steady. The 3 bones of the knee are held together by 4 main ligaments, 2 of which run inside, from top to bottom diagonally and cross each other. Since they cross, they are referred to as cruciate (or crossing) ligaments. The other 2 ligaments are located, one at either side of the joint. A healthy knee is an extremely strong and stable joint, due almost entirely to the holding power of these 4 ligaments. They have half the holding power of steel and are tremendously flexible.

Referred Pain

Referred pain is pain that is felt at a distance from its source. Referred pain in the knee may be coming from your back or your hip. If, for example, you have a prolapsed disc which is pressing on the sciatic nerve the pain can be transmitted along the nerve and be felt anywhere along its path. The further the point of pain from the source the greater the level of damage to the nerve. Back pain that makes your foot sore is usually more serious than if the all the discomfort was in the back. The pain may also be referred to your knee from “trigger points” in your muscles.

Dislocated Kneecap - Patella

The patella is anatomical name for the kneecap. It is embedded in the tendon at the end of the thigh muscles and slides in a groove as the thigh muscle shortens and lengthens. It acts as part of a pulley, sliding over the end of the thigh bone, transferring the pull of the quadriceps muscle when you straighten your knee. In fact, it is involved in every action of the knee joint and every time you move your knee the kneecap glides along its track.

Coccydynia

Your coccyx, also known as the “tail bone” is made up of the lowest 5 bones in the spine. Usually some of the 5 are joined together so that you may have only three or so segments. Your coccyx is as individual as you are, they come in all shapes and sizes! These segments, like all bones are held together by ligaments. Coccydynia is the term for any pain coming from the coccyx area. Pain can start from a blow (kick in the butt), a fall on your bottom, childbirth, or by a small bony growth that inflames a bursa.
