Elbow General Flashcards
Name the two stabilising ligaments
Radial collateral ligament
Ulna collateral ligament
What is found between the radius and ulna
Interosseous membrane
What is the purpose of the annular ligament
Hugs the radius to the ulna/the radial notch of the ulna
What is the function of the quadrate ligament
Limits spin of radial head
Limits pronation and supination
What is the elbow?
A compound synovial joint
What is the capsule?
A fibrous membrane covering the synovial membrane to enclose the joint
What is the humero-radial articulation
Between the capitulum and head of radius
What is the humero-ulnar articulation
Between the trochlear and trochlear notch of the ulna
Where is the inferior radio ulnar joint
Between head of ulna and ulna notch of radius
What is the function of the interosseous membrane ?
Transmits force from hand
Provides area for muscle attachment
Where is the superior radio-ulnar joint
Between head of radius and radial notch of ulna
What are the radio ulnar joints ?
Synovial joints
What is the attachment of the ulna collateral ligament
Proximally attaches to the medial epicondyle
Distally attaches to the medial aspect of the olecranon
What is the attachment of the radial collateral ligament?
Attaches proximally to lateral epicondyle
Distally attaches to annular ligament
Where does the joint capsule attach
Margins of epicondyles, olecranon, neck of radius and coronoid process of ulna
