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.

Hamstring Muscle Strain

Your muscles are made of fibres resembling threads and wrapped in “cling film”. A muscle tear happens when some of these fibres are stretched too much and break. As they break, the severed ends spring back and curl up. This space is then filled with blood which causes the discoloration that appears as bruising after a day or so. Muscles can tear for many reasons, lack of proper warm-up, over stressing, weakness from a previous injury or poor repair. Over-tired, tense or cold muscles damage more easily. The amount and severity of the tear depends on the severity of the stretch or the blow you received.

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.

Supraspinatus Tendinitis

Tendinitis is very common at the shoulder. This tendon is involved in all shoulder movements. It prevents downward drag on the arm as in carrying. The most painful movement involves moving the straight arm out to the side and up over the head. The middle part of this movement causes pain; from 45 to 160 degrees and lowering the arm from this position is also extremely painful.
