Ligaments play a vital role in stabilizing joints, and in the elbow, the ulnar collateral ligament (UCL) and radial collateral ligament (RCL) are key to maintaining proper movement and function. Injury to these ligaments—whether from overuse, trauma, or sports—can result in elbow instability, pain, and limited function. In this blog, we explore how UCL and RCL injuries occur, their symptoms, and treatment options. At the practice of Steven C. Thomas, MD and Donald W Pennington, DO, our board-certified surgeons specialize in orthopedic procedures in the Las Vegas area.
Understanding Elbow Ligaments
- Ulnar Collateral Ligament (UCL): Located on the inside (medial side) of the elbow, the UCL is commonly injured in throwing athletes, especially baseball pitchers.
- Radial Collateral Ligament (RCL): Found on the outer (lateral side) of the elbow, the RCL provides lateral support and can be damaged through trauma or repetitive stress.
Causes of Ligament Injuries
- Repetitive Overhead Motion: Common in baseball, tennis, and javelin.
- Trauma: A fall or direct impact can overstretch or tear elbow ligaments.
- Degeneration: Over time, ligaments can weaken with age or overuse.
Signs and Symptoms of Elbow Instability
- Pain on the inner or outer elbow
- Clicking or popping sensations
- Feeling of the elbow “giving out”
- Reduced throwing velocity or accuracy
- Weakness or instability during pushing or lifting
Diagnosis and Imaging
Diagnosis typically involves a physical examination, range of motion tests, and imaging such as MRI or ultrasound to assess ligament damage.
Treatment Options
- Non-Surgical:
- Rest and activity modification
- Bracing or splinting
- Physical therapy to strengthen surrounding muscles
- Surgical:
- UCL Reconstruction (Tommy John surgery)
- RCL Repair or Reconstruction
Conclusion
Injury to the UCL or RCL can significantly affect elbow function and stability. Early diagnosis and treatment—whether conservative or surgical—can lead to a successful recovery and return to activity. If you suspect a ligament injury, consult an orthopedic specialist for a tailored treatment plan.
