Arthritis is an inflammatory condition of the joints. There are several types of arthritis; the most common type is osteoarthritis or wear-and-tear arthritis that affects the joint at the base of the thumb. Thumb arthritis is more common in women than men, and usually occurs after the age of 40 years. Arthritis of the fingers causes swelling, pain, stiffness and malformation, all of which interfere with the use of the hand.
Sports injuries are injuries that most commonly occur during sports and exercises. These injuries may result from accidents, poor training practices, and use of improper protective gear, lack of conditioning, and insufficient warm-up and stretching. The sports injuries may be either acute (sprains, fractures, tears) or chronic (tendinitis, overuse injury) injuries.
The hand is one of the most flexible and useful parts of our body that enable us to perform many of our daily activities. The hands and wrists are prone to injuries or certain orthopaedic conditions and can range from minor cuts or burns to severe arthritis or injuries of nerves, bones, and tendons.
Inflammation in the tenosynovium leads to a condition called trigger finger, also known as stenosing tenosynovitis or flexor tendonitis, where one of the fingers or thumb of the hand is caught in a bent position. The affected digit may straighten with a quick snap, like pulling and releasing the trigger on a gun, hence the name trigger finger.
