What are the 3 ligaments of the elbow?
There are four main ligaments in the elbow.
- Medial collateral ligament. Located on the inside of the elbow this ligament connects the ulna to the humerus.
- Lateral collateral ligament. Located on the outside of the elbow this ligament connects the radius to the humerus.
- Annular ligament.
- Quadrate ligament.
What are the 2 main ligaments in the elbow called?
Ligaments
- ulnar-collateral ligament, also called the medial collateral ligament, which runs along the inside of the elbow.
- lateral collateral ligament, also called the radial collateral ligament, which runs along the outside of the elbow.
What are the three ligaments of the elbow and what do they connect?
Elbow joint
| Type | Hinge joint |
|---|---|
| Bones | Humerus, radius, ulna |
| Mnemonics | CRAzy TULips (Capitulum = RAdius, Trochlea = ULna) |
| Ligaments | Ulnar collateral ligament, radial collateral ligament, annular ligament, quadrate ligament |
Where does the lateral collateral ligament attach in the elbow?
The lateral collateral ligament (LCL) of the elbow is the ligament on the outside of the elbow, not to be confused with the LCL in the knee. The LCL in the elbow is sometimes also called the radial collateral ligament (RCL). This ligament can become sprained or torn as a result of a sports injury.
What ligament is used for Tommy John surgery?
Tommy John Surgery, more formally known as ulnar collateral ligament (UCL) reconstruction, is used to repair a torn ulnar collateral ligament inside the elbow.
What is LCL in elbow?
The lateral collateral ligament (LCL) of the elbow is a complex capsuloligamentous structure critical in stabilizing the ulnohumeral and radiocapitellar articulations.
What ligament connects the radius and ulna?
The distal radioulnar articulation is composed of the palmar radioulnar ligament (volar radioulnar ligament) that attaches the anterior radius to the anterior ulna, the dorsal radioulnar ligament (posterior radioulnar ligament) which attaches the posterior radius to the posterior ulna, and the articular disc which lies …
What are the elbow ligaments?
The important ligaments of the elbow are the medial collateral ligament (on the inside of the elbow) and the lateral collateral ligament (on the outside of the elbow.) Together these ligaments provide the main source of stability for the elbow, holding the humerus and the ulna tightly together.
What is the lateral ulnar collateral ligament?
The lateral ulnar collateral ligament (LUCL) is an important stabilizing ligament of the elbow. It is involved in many functions of everyday life such as lifting and pushing one’s self out of a chair. This ligament is usually injured by way of a traumatic injury as opposed to overuse and wear.
What muscle is affected in Tommy John surgery?
Tommy John surgery is the reconstruction of the ulnar collateral ligament (UCL) of the elbow. It is most commonly performed after an overhead throwing athlete sustains a high-grade injury to the UCL. A tendon graft from the patient’s forearm or hamstring muscle is used to replace the damaged ligament.
