The Elbow and Radio- Ulnar joints Flashcards
Olecranon
What are the ligaments of elbow joint supported by?
Support to the joint is provided by the thickening of the medial and lateral aspects of the capsule – this forming the medial and lateral collateral ligaments.
Which ligament holds the ulnar in place?
Ulnar collateral ligament
Which ligament holds the head of the radius
Annular ligament
Which muscles cause flexion of the elbow joint:
Brachialis
Biceps brachii
Brachioradialis
Which muscles cause extension of the elbow joint
Chief is triceps brachii

What is students elbow?
The subcutaneous olecranon bursa is one of these structures and can be damaged through repeated excessive pressure and friction. This inflammation (commonly occurring when you’re leaning on them studying) is called olecranon bursitis
What is tennis elbow?
Repetitive overuse of the muscles in the forearm causes inflammation of the muscle tendons attached to the lateral epicondyle of the elbow – this is lateral epicondylitis
What is golfers elbow?
Repetitive overuse of the muscles in the forearm causes inflammation of the muscle tendons attached to the medial epicondyle of the elbow – this is medial epicondylitis
How many points do the radius and ulnar bones articulate?
At 2 points
What type of joints are the radioulnar joints?
Both of these joints (proximal and distal radio-ulnar joints) are pivot type synovial joints, allowing supination and pronation of the forearm.
What is the proximal radio ulnar joint is supported by?
Supported by another ligament arising at the elbow – this keeps the head of the radius in place.
This is the radial collateral ligamnent
What are the moveents of the radioulnar joints?
Supination and pronation
What muscles are involved in supination of the radioulnar joint?
- Supinator
- Biceps brachii
