- Anatomy: Landmarks
- Landmarks form triangle (Elbow at 90 degrees)
- Olecranon
- Lateral epicondyle
- Medial epicondyle
- Landmarks form triangle (Elbow at 90 degrees)
- 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
- Adjacent to humeral condyles
- Provides Forearm muscle insertions
- Flexor-pronator muscles attach to medial epicondyle
- Extensor-Supinators attach to lateral epicondyle
- Humerus
- 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
- Muscle insertions
- 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
- Median Nerve
