Valgus extension overload (VEO)
This is a common injury among athletes who throw as part of their sport and is sometimes known as ‘pitcher’s elbow’.
Causes
When throwing, the olecranon and humerus are twisted, forcing them together. Over time this can cause valgus extension overload (VEO) where the protective cartilage on the olecranon is gradually worn away.
Symptoms
Pain when you extend your elbow and swelling where the bones are in contact with each other, along with the formation of bony lumps around the elbow joint (also known as bone spurs or osteophytes).
Diagnosis
If, after a medical examination, your specialist thinks you may have valgus extension overload, you will be offered an X-ray and an MRI or CT scan to confirm the diagnosis.
Treatment
Non-operative treatment: this includes taking anti-inflammatory medication, if advised by your doctor, along with changing your throwing technique if necessary.
Surgery
Arthroscopic surgery allows your specialist to remove loose bone fragments and clean up the joint (debridement). However, if the condition has caused elbow instability, you may be offered ulnar collateral ligament reconstruction surgery.
