Tennis Elbow

Acute Tennis Elbow is an injury to the muscles that extend the wrist and fingers. The site of injury is typically the lateral epicondyle, a bony bump on the outside of the elbow where these muscles attach.
Tennis Elbow symptoms that have lasted more than 6 weeks are considered to be sub-acute and beyond three months, as chronic tennis elbow.

Acute Tennis Elbow is caused by damaged muscle tissue at the point it anchors to the arm bone at the elbow. It occurs when more force is applied to an area than the normal healthy tissues can handle.

Common Tennis Elbow Causes include:

  • Unaccustomed hand use. Example, painting a fence, hammering, lots of typing.
  • Excessive gripping or wringing activities
  • Poor forearm muscle strength or tight muscles
  • Poor technique (this may be a poor tennis shot)

In some cases such as Chronic Tennis Elbow, this can occur due to the soft tissues being in poor health, which are easily injured. Inflammation follows the injury, which leads to swelling and elbow pain.

Signs and Symptoms

  • Pain on the outer part of the elbow
  • Point tenderness over the lateral epicondyle—a prominent part of the bone on the outside of the elbow
  • Pain from gripping and movements of the wrist, especially wrist extension (e.g. turning a screwdriver) and lifting movements
