Hand & Wrist Conditions

The wrist is comprised of two bones in the forearm, the radius and ulna, and eight tiny carpal bones in the palm. The bones meet to form multiple large and small joints. A wrist fracture refers to a break in one or more of these bones.

The forearm is made up of 2 bones, namely, the radius and ulna. The primary function of your forearm is rotation i.e., the ability to turn your palm up and down. The fracture of the forearm affects the ability to rotate your arm, as well as bend and straighten the wrist and elbow. The breaking of the radius or ulna in the middle of the bone requires a strong force and is most commonly seen in adults. In most of the cases, both bones are broken during a forearm fracture.

Forearm fractures can occur near the wrist, near the elbow or in the middle of the forearm. Apart from this, the bones in children are prone to a unique injury known as a growth plate fracture. The growth plate, which is made of cartilage (flexible tissue) is present at the ends of the bones in children and helps in the determination of length and shape of the mature bone.

Carpal tunnel syndrome is a common, painful, progressive condition that is caused by compression of the median nerve at the wrist area.

Inflammation and swelling of the tendon sheaths put pressure on the adjacent nerves and leads to pain and numbness in the thumb side of the wrist. Strain on these tendons can cause swelling and irritation, and lead to a condition called De Quervain's tenosynovitis, which is characterized by inflammation. The condition is also referred to as De Quervain’s tendinitis, De Quervain’s tendinosis, De Quervain’s syndrome or De Quervain’s disease.

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.

A boxer’s fracture is a break in the neck of the fifth metacarpal bone of the hand (below the pinky finger) close to the knuckle. The hand is composed of 3 types of bones: carpal or wrist bones, metacarpals or long hand bones, and phalanges or finger bones. Metacarpals consist of five long bones that connect the carpal with the phalanges. Structurally, metacarpal bones can be divided into four parts: base, shaft, neck, and head. In some cases, the broken bone can protrude through the skin and is called an open fracture.

A fracture is a break in the bone, which occurs when force greater than the bearable limit is applied against a bone. The most common symptoms of any fracture include severe pain, swelling, bruising or bleeding, deformity and discoloration of the skin and limited mobility of the hand.
