Hand Injuries and Disorders

No matter how old you are or what you do for a living, you are always using your hands. When there is something wrong with them, you may not be able to do your regular activities.

Hand problems include

  • Carpal tunnel syndrome - compression of a nerve as it goes through the wrist, often making your fingers feel numb
  • Injuries that result in fractures, ruptured ligaments and dislocations
  • Osteoarthritis - wear-and-tear arthritis, which can also cause deformity
  • Tendinitis - irritation of the tendons
  • Disorders and injuries of your fingers and thumb

Sprains and Strains

A sprain is a stretched or torn ligament. Ligaments are tissues that connect bones at a joint. Falling, twisting, or getting hit can all cause a sprain. Ankle and wrist sprains are common. Symptoms include pain, swelling, bruising, and being unable to move your joint. You might feel a pop or tear when the injury happens.

A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time. Back and hamstring muscle strains are common. Many people get strains playing sports. Symptoms include pain, muscle spasms, swelling, and trouble moving the muscle.

At first, treatment of both sprains and strains usually involves resting the injured area, icing it, wearing a bandage or device that compresses the area, and medicines. Later treatment might include exercise and physical therapy.

Wrist Injuries and Disorders

Your wrist connects your hand to your forearm. It is not one big joint; it has several small joints. This makes it flexible and allows you to move your hand in different ways.

Ligaments connect bones to each other.

What are the types of wrist injuries and disorders?

Some of the more common types of wrist injuries and disorders are

  • Carpal tunnel syndrome, which happens when a nerve that runs from your forearm into your palm becomes squeezed at the wrist
  • Ganglion cysts, which are noncancerous lumps or masses
  • Gout, which is a form of arthritis caused by a buildup of uric acid in your joints
  • Fractures (broken bones)
  • Osteoarthritis, the most common type of arthritis. It is caused by wear and tear of the joints.
  • Sprains and strains, which are injuries to ligaments and injuries to muscles or tendons
  • Tendinitis, inflammation of a tendon, usually due to overuse
