Study Notes
Elbow Joint Complex: Anatomic Considerations
- Humerocubital Joint: A throclear joint, responsible for flexion and extension
- Humeroradial Joint: A condylar joint, allowing flexion and extension
- Radio-ulnar Joint: A pivot joint involved in supination and pronation. This joint has a physiological valgus.
Range of Motion
- Flexion: Active range 140-145 degrees, Passive range 160 degrees
- Extension: 0-45 degrees
- Supination: 75-90 degrees
- Pronation: 75-90 degrees
Main Elbow Muscles
- Biceps Brachii: Flexes and supinates the elbow
- Triceps Brachii: Extends the elbow
- First Radial: Flexes the elbow
- Second Radial: Flexes the elbow
- Large Supinator: Flexes the elbow, and supinates/pronates forearm.
- Short Supinator: Supinates the forearm.
- Teres Pronator: Flexes the elbow and pronates the forearm
- Anconeus: Extends the elbow
Tests for Elbow Function
- Triceps Dips: Measures repetitions for 1 minute, indicating triceps weakness
- Biceps Muscle Manual Test: Measures repetitions against resistance for biceps weakness and/or injury; strength can also be measured using a dynamometer.
- Cozen Test: Assesses wrist extension and radial inclination for elbow pain, possibly indicating "tennis elbow"
- Golfer Test: Assesses wrist extension and ulnar inclination for elbow pain, possibly indicating "golfer's elbow".
