What is the function of the medial collateral ligament of the elbow?
The medial collateral ligament (MCL) of the elbow of is part of the complex of ligaments and tendons that attach and stabilize the bones of the lower and upper arm where they meet at the elbow joint.
Which collateral ligament is on the medial side of the elbow?
ulnar collateral ligament complex
The ulnar collateral ligament complex is located on the inside of the elbow (pinky or medial side). It is attached on one side to the humerus (the bone of the upper arm) and on the other side to the ulna (a bone in the forearm).
What is the anatomical name for medial collateral ligament?
The medial collateral ligament, which is also known as the tibial collateral ligament, is a broad, flat, bandlike ligament that runs from the medial condyle of the femur to the medial aspect of the shaft of the tibia, where it attaches just above the groove where the semimembranosus muscle attaches (Fig. 107.2).
What is the main purpose of the medial collateral and lateral collateral ligaments?
Collateral ligaments. They control the side to side motion of your knee and brace it against unusual movement. The medial collateral ligament (MCL) is on the inside. It connects the femur to the tibia. The lateral collateral ligament (LCL) is on the outside.
What position is the elbow most stable?
The osseous stability of the elbow is maximized in flexion owing to symmetrical positioning of the coronoid and radial head within their respective fossae (Fig. 1).
What muscles stabilize the elbow?
Triceps brachii: This muscle at the back of the upper arm extends the arm and stabilizes the elbow when the hand is used for fine movements.
Where is medial collateral ligament pain?
MCL injuries hurt. Most people feel pain along the inside edge of the knee, and they also have swelling. You might hear a pop when the damage to the knee takes place, and your knee may lurch to the side.
