Because this bursa lies relatively superficially, it can also become infected (e.g cut from a fall on the elbow) Located on the inside of the elbow this ligament connects the ulna to the humerus. These 3 ligaments together allows for both rotation and stabilization. The annular ligament of the elbow extends from the ulna around the head of the radius to hold the bones of the lower arm together. Ligaments are a group of firm tissues that connect bones to other bones. When refering to evidence in academic writing, you should always try to reference the primary (original) source.

Introduction. Muscles are fibrous tissue capable of contracting to cause body movement. Medial Ulnar Collateral Ligament Injury, or a Tommy John injury, is characterized by attenuation or rupture of the ulnar collateral ligament of the elbow leading valgus instability in overhead throwing athletes; Diagnosis is usually made by a combination of physical exam and MRI. It supplies blood flow to the front of the hand, fingers and thumb. To improve the management outcomes and diagnostic accuracy of the ulnar collateral ligament (UCL) injury, the anatomy of the medial side of the elbow joint is necessary to be understood in terms of the periarticular surroundings rather than the specific ligaments.

The elbow is a complex joint whose stability is imparted by osseous as well as soft … Each of these ligaments can be injured by elbow trauma or overuse. Ligaments of the elbow and forearm (overview) The radial collateral ligament has a low attachment to the lateral epicondyle of the humerus. The elbow joint consists of the humerus (upper arm bone), the Ulna and Radius (forearm bones). The ligaments of the elbow consist of the medial collateral ligament complex with three components of the ulnar collateral ligament (UCL)—the anterior UCL, posterior UCL, and transverse bundle—and the lateral collateral ligament complex with the radial collateral ligament (RCL), lateral UCL, and annular ligament (AL) (1 – 16). Posterior view of the ligaments of the right shoulder joint; Posterior, lateral and medial views of the elbow showing skeletal anatomy in flexed and extended positions; Anterior views of the muscles of the right elbow. This tendon attaches the biceps muscle on the front of the arm to the radius allowing supination, rotation of the elbow. Three bony structures create multiple articulations within the elbow complex. Subcutaneous bursitis: Repeated friction and pressure on the bursa can cause it to become inflamed. radiohumeral: capitellum of the humerus with the radial head ulnohumeral: trochlea of the humerus with the trochlear notch (with separate olecranon and coronoid process articular facets) of the ulna radioulnar: radial head with the radial notch of the ulna (proximal radioulnar joint) The important tendons of the elbow are the biceps tendon, which is attached the biceps muscle on the front of your arm, and the triceps tendon, which attaches the triceps muscle on the back of your arm. If the UCL gets damaged due to any injury, it can result in the elbow becoming unstable. Restraint to varus and posterolateral rotatory instability.Anatomy is more variable.LCL arises from lateral humeral condyle at a point through which the axis of rotation passes – it maintains a uniform tension throughout the arc of motion. Floris S, Olsen BS, Dalstra M et al (1998) The medial collateral ligament of the elbow joint: anatomy and kinematics. The ulnar collateral ligament (UCL, also known as medial collateral ligament) is located on the medial side of the elbow.The UCL complex comprises three ligaments: the anterior oblique, posterior oblique and transverse ligaments. The three bony structures include the distal humerus, proximal radius, and proximal ulna. Floris S, Olsen BS, Dalstra M et al (1998) The medial collateral ligament of the elbow joint: anatomy and kinematics. - Anatomy: - humeral origin of MCL lies posterior to axis of elbow flexion, creating cam effect; - hence, anterior fibers are stressed in extension & posterior fibers are stressed in flexion; - anterior oblique, posterior oblique ligament, & small transverse ligament are 3 major portions of the elbow MCL; During activities such as overhand baseball pitching, this ligament is subjected to extreme tension, which places the overhand-throwing athlete at risk for injury. The bones … The three bones that are responsible for the formation of the elbow joint are humerus, radius and ulna.It includes two articulations: (a) humero-ulnar articulation, between the trochlea of the humerus and trochlear notch of the ulna, and (b) humero-radial articulation, between the capitulum of the humerus and the head of radius. A third ligament, the annular ligament, holds the radial head tight against the ulna. The distal fibres blend with the annular ligament that encloses the head of the radius, as well as with the fibres of the supinator and the extensor carpi radialis brevis muscles. This is the large muscle on the front of the arm above the elbow that allows elbow supination, rotation of the elbow. Ligaments are strong rope like tissue that connects bones to other bones and help hold tendons in place providing stability to joints. The annular ligament encircles the head of the radius, stabilizing it in the radial notch. The medial and ulnar collateral ligaments maintain the stability of the elbow.
