A sore elbow
The ligament injured is the ulnar collateral ligament (UCL) on the inside of the elbow joint. The surgeon must reconstruct the ligament using a tendon from the forearm.
Tommy John surgery is a surgical procedure in which a ligament in the medial elbow is replaced with a tendon from elsewhere in the body (often from the forearm, hamstring, knee, or foot of the patient).
I believe that an arm does have a tendon between the elbow and the shoulder.
The tendon that extends from the wrist to the shoulder is the biceps tendon.
Elbow flexiom
The ligament that attaches the antebrachium (forearm) to the brachium (arm) is called the elbow joint capsule. It is a strong fibrous structure that helps stabilize and support the elbow joint during movement.
None. The ulnar collateral ligament prevents abduction of the elbow joint.
Moveable ligament joints
An inflamed tendon is called tendinitis. This condition occurs when a tendon, which connects muscle to bone, becomes irritated or inflamed, often due to repetitive motion, overuse, or injury. Symptoms typically include pain, swelling, and limited movement in the affected area. Common sites for tendinitis include the elbow, shoulder, knee, and Achilles tendon.
Some examples of ligaments in the human body include the anterior cruciate ligament (ACL) in the knee, the Achilles tendon in the ankle, and the collateral ligaments in the elbow. Ligaments are tough, fibrous connective tissues that connect bones to other bones and help stabilize joints.
It sounds like you dislocated your elbow joint or did some type of ligament or tendon damage. You need to be seen by a physician right away.
