What is valgus extension overload syndrome?

Valgus extension overload (VEO) syndrome is a condition commonly seen in athletes, particularly those involved in repetitive overhead activities like baseball pitching (Cain et al., 2003). The repetitive throwing motion contributes to excessive valgus stress during extension, leading to pain at the posteromedial aspect of the elbow. Over time, this repetitive stress can damage the cartilage and bone, resulting in the formation of osteophytes (bone spurs), and in some cases, loose bodies within the joint's protective cartilage (Andrews & Launer, 2002).

Elbow movement dysfunction and excessive humeral external rotation are key factors contributing to the development of VEO syndrome (VEOS). Stiffness and shortness in the posterior shoulder muscles also contribute to excessive external rotation of the humerus, further impacting the elbow joint’s biomechanics. Weakness in the humeral internal rotators, such as the pectoralis major and latissimus dorsi, can also contribute to excessive humeral external rotation and elbow stress. If left untreated, valgus extension overload can lead to chronic pain and long-term complications, including reduced range of motion and functional limitations.

A thorough physical examination, including specific tests such as the valgus stress test, manual muscle testing, and assessments of symptom reproduction, is crucial for diagnosing this condition. Treatments may include rehabilitating the medial elbow stabilizers and the ulnar collateral ligament, which are essential in maintaining elbow stability during high-stress activities. Injuries to these structures can exacerbate the condition, making targeted rehabilitation essential.

Symptoms

When it comes to identifying VEOS, the symptoms can be fairly specific. Here are some common signs to look out for:

Pain at the posteromedial elbow, especially during elbow extension
Swelling around the elbow joint
Loss of full elbow extension
Locking or catching sensation in the elbow
Tenderness over the medial epicondyle and olecranon
Crepitus (a crackling sound) during elbow movement

Causes

VEOS typically develops due to repetitive stress and mechanical overload on the medial elbow. Here are some common causes:

Repetitive overhead throwing motions (e.g., pitching in baseball)
Excessive valgus stress during elbow extension
Poor biomechanics during athletic activities
Inadequate conditioning or warm-up
Previous elbow injuries that destabilize the joint
Overuse without sufficient rest or recovery time

Conditions like lateral epicondylitis can also exacerbate elbow pain and contribute to valgus extension overload syndrome.

What is the Valgus Extension Overload Test?

The Valgus Extension Overload Test is a clinical assessment to diagnose valgus extension overload syndrome. Although valgus stress testing is the most common method used to diagnose elbow conditions, the Valgus Extension Overload Test is still the most beneficial for identifying posteromedial elbow pain and potential osteophyte formation in athletes who engage in repetitive overhead activities.

The Valgus Extension Overload Test recreates the stresses applied to the elbow during throwing and hitting, aiding in identifying pain and potential joint instability in athletes (Piraino & Davis, 2022).

Pain or discomfort at the posteromedial elbow side indicates a positive result in the Valgus Extension Overload Test. This suggests that the patient may be suffering from valgus extension overload syndrome, warranting further investigation or intervention. On the other hand, a negative result, where the patient does not report pain, reduces the likelihood of this condition but does not entirely rule it out, especially in early or mild cases.

It is important to note that even though the VEO test has several similarities with the Moving Valgus Stress Test and the Elbow Valgus Instability Stress Test (also known as the Elbow Valgus Stress Test), they differ slightly in their procedures, focus, and conditions they aim to assess.

Alternatively, you can save a non-customizable PDF version by clicking "Download," which you can still fill it digitally or print.

Step 2: Fill in patient information

Start by filling out the patient information section. This includes the patient’s name, date of birth, and the date of the test.

Step 3: Conduct the test procedure

To conduct the Valgus Extension Overload Test, follow the steps outlined in the template’s test procedure section. This ensures consistency in how the test is performed and that all necessary actions are taken to obtain reliable results.

Step 4: Document the test results

After conducting the test, use the template to document the results. Note whether the patient experienced pain during the test—this indicates whether it was a positive or negative test.

Step 5: Complete and review

Finally, fill in the healthcare professional information section, including your name, signature, and the date. Review the completed template to ensure all sections are correctly filled out, and the information is accurate before saving or printing it for the patient's records.

Commonly asked questions

Valgus extension overload is most commonly associated with sports that involve elbow range and repetitive overhead motions, such as baseball pitching, tennis, and javelin throwing. Athletes in these sports place significant stress on their elbows, making them more susceptible to this condition.

Yes, many cases of valgus extension overload syndrome can be managed without surgery, especially if diagnosed early. Treatment typically involves rest, physical therapy, and activity modification to reduce excessive stress on the elbow. In rehabilitation programs, activities like soft toss hitting are often included to help athletes recovering from elbow injuries regain their strength and return to their sport. However, severe cases with significant osteophyte formation or loose bone fragments may require surgical intervention.

Athletes can help prevent valgus extension overload syndrome by maintaining proper biomechanics during their sport, ensuring adequate warm-up and conditioning, and allowing for sufficient rest and recovery time between activities. Regular monitoring and early intervention when symptoms arise can also be crucial in prevention.
