V. Anatomy: Landmarks
- Landmarks form triangle (Elbow at 90 degrees)
- Olecranon
- Lateral epicondyle
- Medial epicondyle
VI. Anatomy: Bone
-
Humerus
- Widens distally forming lateral and medial epicondyles
- Radial Head
- Articulates with capitellum (at lateral epicondyle)
- Articulates with lateral ulna
- Held in position by orbicular ligament
- Easily palpable near lateral epicondyle
- Ulna
- Articulates with Trochlea (at Medial epicondyle)
- Epicondyles
VII. Anatomy: Soft tissue
-
Muscle insertions
- Triceps attaches to Olecranon posteriorly
- Biceps and brachialis attach to radius and ulna
- Pronators and Supinators Mnemonic
- MFP: medial (epicondyle) flexors and pronators
- LES: lateral (epicondyle) extensors and supinators
- Collateral Ligaments
- Medial and Lateral collateral ligaments add stability
VIII. Anatomy: Nerves
-
Median Nerve
- Deep in antecubital fossa
- Medial to biceps
-
Radial Nerve
- Lateral to biceps and brachialis Muscles
-
Ulnar Nerve
- Posterior to medial epicondyle
- In groove between medial epicondyle and Olecranon
- Superficial, and vulnerable to injury

Ontology: Elbow Injuries and Disorders (C1456829)
Definition (MEDLINEPLUS) |
Your elbow joint is made up of bone, cartilage, ligaments and fluid. Muscles and tendons help the elbow joint move. When any of these structures is hurt or diseased, you have elbow problems. Many things can make your elbow hurt. A common cause is tendinitis, an inflammation or injury to the tendons that attach muscle to bone. Tendinitis of the elbow is a sports injury, often from playing tennis or golf. You may also get tendinitis from overuse of the elbow. Other causes of elbow pain include sprains, strains, fractures, dislocations, bursitis and arthritis. Treatment depends on the cause. |
