Valgus extension overload (VEO)
Valgus extension overload (VEO) can cause pain at the back and inside of the elbow, particularly during throwing or overhead sports. Over time, it can make it increasingly difficult to train, compete or even carry out everyday activities comfortably.
What is valgus extension overload (VEO)?
Valgus extension overload (VEO), sometimes called pitcher's elbow, is an overuse injury caused by repeated throwing or overhead movements that place excessive stress on the elbow joint. Over time, this repeated strain can damage the cartilage at the back of the elbow, particularly around the tip of the elbow bone (the olecranon). It may also irritate the surrounding soft tissues and lead to the formation of small bony growths, known as bone spurs (osteophytes), which can further limit movement and cause pain. VEO most commonly affects athletes involved in sports such as baseball, cricket, javelin, tennis and handball, but it can develop in anyone who regularly performs repetitive overhead activities. Because valgus extension overload is often linked with injuries to the ulnar collateral ligament (UCL), it's important to have persistent elbow pain assessed by a specialist so that any associated problems can be identified and treated appropriately.
What are the symptoms?
Symptoms usually develop gradually and may include:
- Pain at the back or inside of the elbow, particularly when straightening the arm
- Pain during or after throwing or overhead activities
- Swelling around the elbow
- Reduced range of movement
- A catching, locking or clicking sensation in the joint
- Tenderness around the back of the elbow
- Bony lumps caused by bone spurs (osteophytes)
How is it diagnosed?
Your consultant will begin by talking with you about your symptoms, sporting activities and how your elbow is affecting your performance and daily life. They'll then examine your elbow, checking its movement, stability and any areas of tenderness.
To confirm the diagnosis and rule out other causes of elbow pain, we may recommend:
- A detailed medical history
- Physical examination
- Assessment of elbow movement, stability and throwing-related symptoms
- X-rays to identify bone spurs or changes within the joint
- MRI or CT scans where further assessment of the cartilage, ligaments or surrounding structures is needed
How is it treated?
Treatment depends on the severity of your symptoms, how the condition is affecting your elbow and your personal goals.
Your consultant will explain your options clearly and recommend the approach that's most appropriate for you.
Treatment may include:
- Temporarily reducing or modifying activities that aggravate your symptoms
- Anti-inflammatory medication if appropriate
- Physiotherapy to improve strength, flexibility and elbow function
- Assessment and correction of throwing technique where appropriate
- A gradual return-to-sport programme
- Surgery if symptoms continue despite non-surgical treatment or if there is significant joint damage or elbow instability

Treatment routes for VEO
Most people with valgus extension overload improve without surgery.
Treatment usually involves reducing repetitive stress on the elbow while improving strength, flexibility and throwing mechanics through a personalised rehabilitation programme. Your physiotherapist will also help you address any movement patterns that may be placing excessive strain on the joint, helping you return to activity with greater confidence.
Recovery goals after VEO
Recovery initially focuses on:
Reducing pain and inflammation Protecting the elbow while symptoms settle Beginning gentle movement when appropriate Preventing stiffness
As rehabilitation progresses, recovery aims to:
Restore elbow movement Improve strength and stability Optimise throwing mechanics where appropriate Return to normal daily activities
The final stage of rehabilitation focuses on:
Building strength and endurance for sport Improving control and coordination Returning safely to throwing and overhead activities where appropriate Reducing the risk of further injury

VEO FAQs
Valgus extension overload is usually caused by repeated throwing or overhead movements that place excessive stress on the elbow. It is most common in sports such as baseball, cricket, javelin and tennis, where the elbow is repeatedly forced into extension under load.
Yes. Most people improve with non-surgical treatment, including physiotherapy, activity modification and improving throwing technique. Surgery is usually only considered if symptoms continue despite appropriate rehabilitation or if there is significant joint damage or instability.
No, but the two conditions are closely linked. Valgus extension overload affects the back of the elbow joint, while a UCL injury involves one of the main stabilising ligaments on the inside of the elbow. Some people have both conditions, so a specialist assessment is important.
Recovery varies depending on the severity of the condition and whether surgery is needed. Many people improve over several weeks to a few months with physiotherapy, while recovery after surgery typically takes longer and includes a structured rehabilitation programme.
Most people are able to return to sport once pain has settled, strength has been restored and elbow function has improved. Your rehabilitation programme will include a gradual return to throwing or overhead activity to help reduce the risk of further injury.
