Valgus Extension Overload (Pitcher’s Elbow)
Valgus extension overload (VEO), commonly known as “pitcher’s elbow,” is a condition that affects the elbow due to repetitive stress from throwing or overhead activities. It results in excessive force on the joint, leading to pain, inflammation, and potential structural damage.
Early evaluation and treatment by an orthopedic specialist are important to relieve symptoms, protect the elbow, and allow a safe return to activity.
What Is Valgus Extension Overload?
Inner elbow pain during throwing activities is a hallmark of valgus extension overload, also known as pitcher’s elbow.
Valgus extension overload occurs when repetitive throwing places stress on the elbow, creating a combination of forces:
- Valgus stress on the inner (medial) side of the elbow
- Compression on the outer (lateral) side
- Impingement at the back (posterior) of the elbow
Over time, this repetitive stress can lead to:
- Bone spur formation (osteophytes)
- Cartilage damage
- Ligament strain (especially the ulnar collateral ligament)
- Inflammation of soft tissues
This condition is most commonly seen in baseball pitchers and other throwing athletes.
Common Symptoms of Valgus Extension Overload
Symptoms often develop gradually and worsen with continued activity. Common signs include:
- Pain at the back or inner side of the elbow
- Pain during or after throwing
- Decreased throwing performance
- Stiffness or reduced range of motion
- Catching, locking, or clicking sensations
- Swelling or tenderness
If you are experiencing elbow pain with throwing, an orthopedic evaluation is recommended.
Causes and Risk Factors
Valgus extension overload is caused by repetitive stress on the elbow joint. Common contributing factors include:
- Frequent or high-volume throwing
- Poor throwing mechanics
- Inadequate rest between activities
- Overuse or early return to sport after injury
Risk factors may include:
- Participation in baseball, softball, or other throwing sports
- High pitch counts
- Year-round play without rest
An orthopedic specialist at UTHealth Houston can evaluate your condition and determine contributing factors.
How Is Valgus Extension Overload Diagnosed?
Diagnosis begins with a physical examination and a review of symptoms and activity history. Orthopedic providers will assess range of motion, pain with extension, and elbow stability.
Imaging studies may include:
- X-rays to identify bone spurs or joint changes
- MRI to evaluate cartilage and ligament involvement
- CT scans in more complex cases
These tests help confirm the diagnosis and guide treatment planning.
Valgus Extension Overload Treatment Options
Non-Surgical Treatments
Many patients can improve with conservative care, including:
- Rest and activity modification
- Temporary restriction from throwing
- Physical therapy to improve strength and mechanics
- Gradual return-to-throwing programs
- Anti-inflammatory medications
Surgical Treatment
Surgery may be recommended for persistent symptoms or structural damage.
Surgical options may include:
- Arthroscopic removal of bone spurs or loose bodies
- Debridement of damaged tissue
- Treatment of associated ligament injuries
The goal of surgery is to relieve pain, restore function, and allow safe return to sport.
When to See an Orthopedic Specialist
You should seek orthopedic care if you experience:
- Persistent elbow pain with throwing
- Decreased performance
- Stiffness or limited motion
- Catching or locking sensations
Early evaluation can help prevent progression and long-term joint damage.
