Elbow Ligament Injuries
What are Elbow Ligament Injuries?
Elbow ligament injuries affect the strong bands of fibrous tissue that connect the bones of the elbow joint and help stabilize the joint. These ligaments stabilize the elbow and enable smooth, controlled movement. Acute or chronic injury can cause joint laxity and loss of function.
Anatomy of the Elbow
The elbow is a hinge joint in the arm made up of three bones, namely, the humerus, ulna, and radius. The humerus forms the upper portion of the elbow, while the radius and ulna together form the lower portion of the elbow.
The elbow joint is supported by the ulnar collateral ligament, radial collateral ligament, and the annular ligament, which together provide strength and stability for various arm movements.
Causes of Elbow Ligament Injuries
The causes of elbow ligament injuries mainly fall into two categories:
Trauma-related: Injury from direct impact, fall, or forceful twisting motions can damage ligaments and may be associated with fractures or dislocations.
Overuse injuries: Repetitive stress can strain the medial collateral ligament, often from frequent bending or outward movement of the elbow.
Symptoms of Elbow Ligament Injuries
The common symptoms associated with elbow ligament injuries include:
- Presence of swelling near the elbow
- Elbow pain
- Pain during certain wrist movements
- Swelling along the length of the arm
- Visible instability in the elbow joint
Diagnosis of Elbow Ligament Injuries
Your doctor will review your symptoms, medical history, and perform a thorough physical examination to check for range of motion, stability, and strength of the joint.
Additional diagnostic tests may be ordered that include X-rays, MRI, and CT scans.

Treatment for Elbow Ligament Injuries
Surgical or non-surgical treatments may be used for elbow ligament injuries, depending on the type and severity of the injury.
Non-surgical methods include:
- Allowing the ligaments to heal by avoiding activities that aggravate symptoms and resting the joint.
- Applying an ice pack to the affected area regularly for short periods of time to reduce inflammation.
- Using splints or braces to stabilize the arm and reduce stress on the injured tissue.
- Using steroid injections or anti-inflammatory medication to reduce pain and swelling.
- Performing physical therapy exercises to improve joint strength and stability.
Surgical methods include:
- Medial collateral ligament reconstruction surgery: This procedure helps restore elbow stability after a complete tear or rupture of the ligament on the inside of the elbow, usually caused by repetitive activity.
- Lateral collateral ligament surgery: This surgery repairs a torn or ruptured ligament on the outside of the elbow, usually caused by a fracture or dislocation. Open reduction and internal fixation may be needed because of decreased joint stability from the fracture or dislocation.
