For throwing athletes, the elbow quietly absorbs an incredible amount of force with every pitch, throw or overhead motion. Over time, that repeated stress can take a toll.
One of the most well-known results of this strain is a UCL injury, also called a Tommy John injury, a condition involving damage to the ulnar collateral ligament (UCL) on the inside of the elbow.

What Is a Tommy John Injury?
The ulnar collateral ligament runs along the inner side of the elbow and plays a critical role in stabilizing the joint during overhead throwing. Every time an athlete tries to generate speed and power, the UCL helps resist the intense torque placed on the elbow. Over time, repetitive stress can weaken this ligament, leading to inflammation, partial tearing or a complete rupture — an injury which may require Tommy John surgery.
Why Is It Called Tommy John Surgery?
This nickname for treating UCL injuries refers to Major League Baseball pitcher Tommy John, the first person to successfully undergo this procedure, saving his career. The innovative technique, formally called UCL reconstruction, was referred to as a Tommy John surgery after its success — the injury follows the same naming convention.
Who Can Get a Tommy John Injury?
Tommy John injuries aren’t limited to professional baseball players. They can affect youth athletes, collegiate competitors and anyone who performs repetitive overhead motions. When the UCL becomes strained or torn, athletes often notice pain along the inner elbow and a loss of throwing velocity or control.
Throwing athletes place especially high demands on this structure, which is why UCL injuries are most common in sports like baseball, softball, javelin and even gymnastics.
UCL Injury Symptoms
Athletes with a UCL injury may experience:
- Pain or soreness on the inside of the elbow
- Decreased throwing velocity or accuracy
- A feeling of looseness or instability in the elbow
- Pain during or after throwing
- In some cases, numbness or tingling in the ring and small fingers
Symptoms often worsen with continued throwing and may eventually interfere with daily activities, not just sports.
What Causes UCL Injuries?
Tommy John injuries typically develop as overuse injuries rather than from a single traumatic event. Repetitive, high-velocity throwing is a key contributing factor, especially when compounded with inadequate rest between games or seasons, poor throwing mechanics, throwing while fatigued and rapid increases in training intensity.
Younger athletes are particularly vulnerable when year-round play or showcase events limit opportunities for recovery.
Tommy John Injury Treatment
Treatment for a Tommy John injury depends on the extent of ligament damage and the athlete’s goals.
Nonsurgical treatment is often the first step, especially for minor strains or partial tears, and may include:
- Rest and activity modification
- Physical therapy to restore strength and flexibility
- Adjustments to throwing mechanics
- Anti-inflammatory medications
- Platelet-rich plasma (PRP) injections in select cases
Many athletes are able to return to play with conservative treatment when injuries are identified early.
Tommy John Surgery
Surgical treatment may be recommended when pain persists, the ligament is unstable or a complete tear is present — particularly for athletes who wish to continue throwing at a competitive level.
The most well-known procedure is UCL reconstruction, commonly referred to as Tommy John surgery. During this procedure, the damaged ligament is replaced with a tendon graft to restore stability and function. In some cases, the ligament can be repaired or reinforced rather than fully reconstructed.
How Long Does It Take to Recover from UCL Injuries?
Athletes who respond to nonsurgical care may return to throwing within a few months. Surgical recovery is more extensive and often includes several phases of rehabilitation, typically taking a year before athletes are back to their previous level.
