Elbow Dislocation
The elbow is a hinge joint made up of 3 bones – humerus, radius and ulna. The bones are held together by ligaments, to provide stability to the joint. Muscles and tendons move the bones around each other and help in performing various activities. Elbow dislocation occurs when the bones that make up the joint are forced out of alignment.
Elbow dislocations usually occur when a person falls onto an outstretched hand. Elbow dislocations can also occur from any traumatic injury such as motor vehicle accidents. When the elbow is dislocated, you may have severe pain, swelling and inability to bend your arm. Sometimes, you cannot feel your hand or may have no pulse in your wrist because arteries and nerves running along your elbow may be injured.
To diagnose elbow dislocation your doctor will examine your arm. Your doctor will check the pulses at the wrist and evaluate circulation to the arm. An X-ray is necessary to determine if there is a break in the bone. An arteriogram, an X-ray of arteries can be helpful to know if an artery is injured.
An elbow dislocation is a serious injury, and therefore, requires immediate medical attention. At home, you may apply an ice pack to the elbow to ease pain and swelling. However, it is important to seek help from your doctor. You can also check if the arteries and nerves are injured or are intact. You can feel your pulse by pressing the tips of your fingers at the base of your wrist. They should turn white or blanch and turn pink in 3 seconds. To check for nerve damage, see if you can bend your wrist up and move your fingers apart and then touch your thumb to your little finger. You can also check for numbness all over your hand and arm. If you have problems carrying out any of these tests, you need to see your doctor right away.
You doctor will put your dislocated elbow back in place by pulling down your wrist and levering your elbow. This procedure is known as reduction. As it is a painful procedure, you may be given medications to relieve your pain before the procedure. After the reduction, you may have to wear a splint to immobilise your arm at the elbow. After a few days, you may also need to do gentle motion exercises to improve the range-of-motion and strength.
