What causes golfer's elbow

Overview

Golfer's elbow, medically termed medial epicondylitis, is a painful condition affecting the tendons of the forearm that attach to the bony prominence on the inside of the elbow, known as the medial epicondyle. Despite its name, it is not exclusive to golfers and can affect anyone who engages in activities involving repetitive wrist and forearm movements. The condition is characterized by inflammation and microtears in these tendons, leading to pain, tenderness, and sometimes stiffness in the affected area.

What Causes Golfer's Elbow?

The primary cause of golfer's elbow is overuse and repetitive stress on the tendons of the forearm. These tendons are responsible for flexing the wrist (bending it forward) and pronating the forearm (turning the palm downward). When these muscles and their tendons are subjected to excessive or forceful repeated motions, they can become inflamed and damaged. This can occur through various activities:

Repetitive Gripping and Lifting:

Activities that involve a strong or repetitive grip, such as lifting heavy objects, using tools, or playing sports like tennis, baseball, or indeed golf, can place significant strain on the forearm flexor tendons. Each time you grip, these muscles contract, and if this action is repeated many times, the tendons can become overloaded.

Throwing Activities:

Sports that involve throwing, like baseball or javelin, require forceful and rapid contractions of the forearm muscles. The acceleration and deceleration phases of throwing can put immense stress on the medial epicondyle and its associated tendons, leading to injury.

Manual Labor and Occupational Hazards:

Many occupations require repetitive arm and wrist movements. Construction workers, plumbers, mechanics, carpenters, and even computer users who spend long hours typing can develop golfer's elbow due to the constant strain on their forearm muscles. Tasks involving hammering, drilling, or prolonged typing can all contribute.

Sudden Increase in Activity:

A common trigger for golfer's elbow is a sudden increase in the intensity or duration of activities that involve the forearm muscles. For example, someone who doesn't regularly play golf might decide to play a full 18 holes and experience pain afterwards. Similarly, starting a new exercise routine that heavily involves grip strength can also lead to symptoms.

Poor Technique or Biomechanics:

Incorrect form or technique during sports or work activities can also contribute to golfer's elbow. For instance, a golfer with poor swing mechanics might place excessive stress on their elbow. Similarly, improper lifting techniques can overload the forearm tendons.

Direct Trauma:

While less common than overuse, a direct blow to the inside of the elbow can also cause injury to the tendons and surrounding tissues, potentially leading to golfer's elbow.

Age:

As people age, tendons can become less flexible and more susceptible to injury. This means that older individuals might be more prone to developing golfer's elbow from activities that younger individuals could handle without issue.

Understanding the Anatomy

The medial epicondyle is a bony protrusion on the inner side of the humerus (upper arm bone) near the elbow joint. Several muscles originate from this point, including the pronator teres and the flexor carpi radialis. These muscles are crucial for rotating the forearm and flexing the wrist. When these muscles are overused, the tendons connecting them to the medial epicondyle can become inflamed, leading to the pain and discomfort associated with golfer's elbow.

Risk Factors

Certain factors can increase an individual's risk of developing golfer's elbow:

• Age: Most common between the ages of 30 and 50.
• Occupation: Jobs involving repetitive arm motions, heavy lifting, or forceful gripping.
• Sports Participation: Engaging in sports like golf, tennis, bowling, or weightlifting.
• Obesity: Excess body weight can put additional strain on joints and connective tissues.
• Smoking: May impair healing and increase the risk of tendon injuries.

In essence, golfer's elbow arises from the cumulative effect of repetitive microtrauma to the forearm tendons. When the stress placed on these tendons exceeds their capacity to repair, inflammation and pain ensue.
