Causes of lateral epicondylitis or tennis elbow
Tennis elbow is usually caused by overuse of the forearm muscles, but can also be caused by direct trauma (less common) , such as a fall, car accident or work injury.
Repetitive arm movements can cause muscles to become fatigued.
As the muscle tires, the tendon bears more load. This overload can cause inflammation and localized pain, known as tendonitis (inflammation at the insertion of the tendon into the corresponding bone).
With each muscle contraction, the tendon is stretched, causing pain. Over time, this overload can cause a degenerative condition known as tendinosis.
Together, tendinitis and tendinosis can be a risk factor for tendon rupture.
Tennis elbow is commonly seen in tennis players, hence its name.
We must visualize the “forehand liftada” of the Spanish players. Where a forced flexion movement of the elbow and wrist is performed, together with a pronation movement of the forearm. The sum of both movements in a repeated way increases the clinic.
Other common causes are activities that require a repetitive movement of the forearm, such as painting, hammering, typing, playing musical instruments...
What are the symptoms of tennis elbow?
Tennis elbow or lateral epicondylitis is usually the result of overuse.
Symptoms usually appear progressively and pain may worsen over weeks or even months.
Lateral epicondylitis or tennis elbow presents one or more of the following symptoms:
Sensation of heat and/or pain on the outside of the elbow, which may move to the wrist (these sensations may worsen at night). Pain when turning or bending the arm (e.g., to turn a doorknob or open a jar). Pain on the outside of the elbow radiating to the forearm and wrist when grasping objects. Decreased grip strength and/or pain that increases when the wrist is bent. Stiffness or pain when extending the arm. Elbow joint swollen and tender to the touch.
