Introduction

Background

Lateral epicondylitis, or tennis elbow, is the most common overuse injury of the elbow and is observed up to 10 times more frequently than medial epicondylitis. Lateral epicondylitis is usually precipitated by repetitive contraction of the wrist extensors and is characterized by aching pain that is worsened with activity. Early conservative management is the key to symptom resolution, which eventually allows return to vocational and avocational activities without restriction.1,2,3

Pathophysiology

Lateral epicondylitis is a result of inflammation, or enthesitis, at the muscular origin of the extensor carpi radialis brevis (ECRB). This inflammation leads to microtears of the tendon, with subsequent fibrosis and, ultimately, tissue failure. Less commonly, the attachments of the extensor carpi radialis longus (ECRL), extensor digitorum communis (EDC), or extensor carpi ulnaris (ECU) are involved.4,5,6

Sex

The condition affects men and women with equal frequency.

Age

Lateral epicondylitis most often occurs between the third and fifth decades of life.

Clinical

History

The patient usually describes a gradual onset of lateral elbow pain, which is characterized as follows:

  • The aching pain generally increases with activity. The patient may describe symptoms occurring during simple activities of daily living (ADL), such as picking up a cup of coffee or a gallon of milk.
  • Pain may be present at night.
  • Symptoms are typically unilateral.

Physical

Most commonly, the examination reveals localized tenderness to palpation just distal and anterior to the lateral epicondyle. Other symptoms include the following7 :

  • Pain increases with resisted wrist extension, especially with the elbow in extension.
  • The patient may have a weakened grip on the affected side.
  • Elbow range of motion (ROM) is typically normal.
  • In chronic, refractory cases, be sure to fully assess shoulder integrity and scapular stability. Weakness or instability of the scapular stabilizers may perpetuate lateral epicondylitis by leading to overuse of the wrist extensors.

Causes

  • Lateral epicondylitis is an overuse syndrome generally caused by repetitive use of the wrist extensors or sustained power gripping.8
  • Lateral epicondylitis can be associated with an imbalance secondary to muscle weakness and soft-tissue inflexibility.
