Elbow- Clinical Assessment Flashcards
What is the classification of the elbow joint
synovial hinge joint
what are the articulating bones of the elbow
humerus, radius and ulna
What cartilage is present, and what is its function
hyaline cartilage on articular surfaces
Allows friction free movement, and acts as a shock absorber
Name of the bursa, and location in the elbow
Olecranon bursae between the olecranon and the overlying connective tissue
Purpose of the synovial capsule
synovial membrane lines the capsule, producing synovial fluid which nourishes cartilage, removes waste and reduces friction
What are the ligaments in the elbow
radial collateral (lateral) ulna collateral (medial)
how many degrees of freedom does the elbow have
1 degree of freedom
What actions does the elbow do (alone)
Flexion and extension
What actions does the superior radio-ulnar joint do (alone)
pronation and supination
What is the blood supply of the elbow
branches from the brachial and deep brachial arteries
what nerves supply the elbow
median nerve musculocutaneous nerve (for biceps) radial nerve (anterior) ulna nerve (posterior)
Name the elbow flexor muscles
brachialis, brachioradialis and biceps brachii
Name the elbow extensor muscles
triceps brachii and anconeus (weak)
What is the ligament in the superior radio-ulnar joint
annular ligament of radius
what type of joint classification is the superior radio-ulnar joint
synovial pivot joint
