What lies on the ulnar collateral ligament?
What lies on the ulnar collateral ligament?
The ulnar collateral ligament (UCL) or internal lateral ligament is a thick triangular ligament at the medial aspect of the elbow uniting the distal aspect of the humerus to the proximal aspect of the ulna.
What does the lateral collateral ligament elbow do?
The lateral collateral ligament (LCL) complex is the soft tissue component that confers stability to varus stress of the elbow joint. The supinator, common extensor origin, anconeus and brachialis provide additional dynamic muscular stabilization of the LCL complex.
Where does the ulnar collateral ligament insert?
The UCL originates at the posterior distal aspect of the medial epicondyle and inserts into the base of the coronoid process. At 90 º of flexion, it provides 55% of the resistance to valgus stress at the elbow.
How do you test ulnar collateral ligament?
A UCL tear can be diagnosed through a history and physical examination. A valgus stress test, during which a physician tests your elbow for instability, is the best way to assess the condition of the UCL. An MRI scan and X-ray may also be used to see the changes in the ulnar collateral ligament related to stress.
Is the ulnar collateral ligament medial or lateral?
The medial (ulnar) collateral ligament (MCL) supports the ulnohumeral and radiohumeral joints medially, and is a fan-shaped structure. The lateral (radial) collateral ligament (LCL) also supports the ulnohumeral and radiohumeral joints, but laterally. It is more of a cord-like structure.
How do you treat radial collateral ligament injury?
Physical therapy can help restore strength and range of motion of the elbow as well as strengthen muscles surrounding the elbow to alleviate tension on the RCL. Non-steroidal anti-inflammatory medications along with resting and icing the elbow can help manage pain and inflammation.
How do you tell if you have a torn ligament in elbow?
Symptoms of an elbow ligament or tendon tear can vary based on the injury and location….Elbow ligament and tendon tear symptoms

- Reduced range of motion around the arm, elbow, forearm or wrist.
- Stiffness around the elbow.
- Swelling.
- Weakness in the hands and wrists.
Why is Tommy John surgery called?
The goal of the surgery is to stabilize the elbow, reduce or eliminate pain and restore stability and range of motion. This procedure was introduced and first performed by Frank Jobe, M.D., on baseball pitcher Tommy John in 1974—hence the colloquial name Tommy John surgery.
