The medial collateral ligament of the elbow is vital for stability and function. Diagnosis usually involves imaging studies and physical examinations. Treatment options range from non-operative methods like bracing and therapy to surgical procedures such as the docking technique.
A MCL tear is an elbow injury that is occasionally seen in clinical practice, and is characterized by overstretching or tearing of the Medial Collateral Ligament (MCL) of the elbow. A ligament is a strong band of connective tissue which attaches bone to bone.
Medial Ulnar Collateral Ligament Injuries are characterized by attenuation or rupture of the ulnar collateral ligament of the elbow leading to valgus instability in overhead throwing athletes. Diagnosis is usually made by a combination of physical exam and MRI studies.
Specifically, the elbow contains two collateral ligaments: the medial collateral ligament (MCL, also known as ulnar collateral ligament, or UCL) and the lateral collateral ligament (LCL). Each of these two ligaments is made up of smaller ligamentous portions.
The medial collateral ligament (MCL) of the elbow is situated on the inside of the elbow. It helps to provide stability to the joint. The ligament is injured from a sudden traumatic injury, or from repetitive overuse, for example throwing with poor technique.
It’s much easier to use strategies for maintaining elbow reduction (repair or replacement of all fractures, suture reattachment of avulsed collateral ligaments, and selective temporary mechanical maintenance of reduction (eg cross pins, external fixation, internal fixation)).
This article reviews the MR imaging protocols recommended for each diagnosis and the normal anatomy and biomechanical aspects of the medial and lateral collateral ligament complex. We also present multiple cases of typical and atypical patterns of injury.
It is sometimes also referred to as the medial collateral ligament (MCL) of the elbow (not be confused with MCL of the knee.) The UCL attaches the ulna bone (which, along with the radius, is one of the two bones of the lower arm) to the humerus bone of the upper arm.
The medial collateral ligament (MCL) of the elbow is on the inside of the elbow and helps to provide stability to the joint. A tear of this ligament occurs either as a sudden onset acute injury or as a chronic, gradual onset injury through overuse. Symptoms include: Pain and tenderness on the inside of the elbow; Bruising
The ulnar collateral ligament extends from the medial epicondyle of the humerus to the coronoid process of the ulna. It is triangular in shape, and is composed of three parts: an anterior, a posterior and an inferior band.
