Hand & Wrist
The hand is one of the most flexible and useful parts of our body. Because of overuse in various activities, the hands are more prone to injuries, such as sprains and strains, fractures and dislocations, lacerations and amputations while operating machinery, bracing against a fall and sports-related injuries.
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.
The diagnosis of a hand fracture is based on history, physical examination and X-ray imaging to determine the type and severity of the fracture. X-rays are the most widely used diagnostic tools for the evaluation of fractures.
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.
Types of wrist fracture include:
- Simple wrist fractures in which the fractured pieces of bone are well aligned and stable.
- Unstable fractures are those in which fragments of the broken bone are misaligned and displaced.
- Open (compound) wrist fractures are severe fractures in which the broken bones cut through the skin. This type of fracture is more prone to infection and requires immediate medical attention.
Wrist fractures may be caused due to a fall on an outstretched arm, vehicular accidents or workplace injuries. Certain sports such as football, snowboarding, or soccer may also be a cause of wrist fractures. Wrist fractures are more common in people with osteoporosis, a condition marked by brittleness of the bones.
Signs and Symptoms
Common symptoms of a wrist fracture include severe pain, swelling, and limited movement of the hand and wrist. Other symptoms include:
- Deformed or crooked wrist
Your doctor performs a preliminary physical examination followed by imaging tests such as an X-ray of the wrist to diagnose a fracture and check alignment of the bones. Sometimes a CT scan may be ordered to gather more details of the fracture, such as soft tissue, nerves or blood vessel injury. MRI may be performed to identify tiny fractures and ligament injuries.
Your doctor will order a bone scan to identify stress fractures due to repeated trauma. The radioactive substance injected into the blood gets collected in areas where the bone is healing and is detected with a scanner.
