Radial head fractures are caused when you fall onto your outstretched hand or land on the outer elbow. The radial head is the bulge at the top of the radius that makes a joint with the ulna and humerus. According to the American Academy of Orthopaedic Surgeons, women are more prone to this type of injury, and between 10 percent and 15 percent of all elbow fractures are accompanied by fractures of the radial head. According to the AAOS, isometric exercises are recommended to aid in rehabilitation after a radial head fracture. Rehabilitation helps reduce pain and return function to the elbow.
Isometrics
Isometric exercises, or isometrics, are strength-training exercises done in static positions. This means that, unlike traditional strength-training exercises, the angle of the joint does not change. Exercises can be overcoming or yielding, depending on whether the resistance is an immovable force or opposing. An example of an overcoming isometric exercise is pressing against a brick wall. A yielding isometric exercise is holding position against someone pressing on your palms.
Static Bicep
The static bicep exercise is simple yet effective. Grasp a lightweight dumbbell and bend your elbow to about 80 degrees and hold. The posture is exactly the same as in a bicep curl, but without the movement. Breathe normally and hold for 10 to 15 seconds. Repeat five times. If time is not a factor, repeat once for each angle of the elbow range.
Elbow Flexion
The elbow flexion exercise is another isometric exercise used to help strengthen the arm. Sit at a table with your hands underneath the table, pressed palm-up into the table. Try to lift your hands up into the table without straightening your arms. Breathe normally and hold the position for five to 10 seconds. Repeat five times.
Caution
Isometric exercises raise your blood pressure so do be careful if you have high blood pressure. Always breathe steadily throughout the session to ensure the brain gets enough oxygen -- never hold your breath. This will also help keep blood pressure from rising dangerously. See a doctor before starting any isometric programs on your own. Follow your therapist's recommendations in order to achieve success in your rehabilitation and avoid any movements that cause pain. A "no pain, no gain" attitude will only result in further injury. Do not perform any heavy lifting or weight-bearing exercises such as push-ups. Avoid push/pull movements.
