Elbow, Wrist And Hand Flashcards
Describe and palpate the joint line of wrist
Radiocarpal joint which is a synovial condyloid joint it acts as a transition point for between the forearm and hand
What are the ligaments of the wrist
Palmer and dorsal radiocarpal ligaments
Ulner and radial collateral ligaments
Describe two muscles acting on the wrist
Flexor Carpi radials - flexion, radial deviation
Palmaris longus- flexion
What are the bony points of the elbow
Medial and lateral epicondyles
Olecranon
Radial head
Describe joint line of elbow
Synovial hinged joint. Made up of three bones the humerus, ulna and radius. The ends of the bone are covered in cartilage allowing the joint to slide easily against one another
What are the Ligaments of elbow
Radial collateral ligaments, ulner collateral ligaments, annular ligament and quadrate ligament
Muscles acting on the elbow
Brachialis
Anconeus
What muscles are involved with supination and pronation
Supinator
Biceps brachii
Wrist: origin and insertion of palmer radiocarpal ligament
Radial styloid process to scaphoid
Wrist: origin and insertion of dorsal radiocarpal ligament
Distal radius to sigmoid notch
Elbow: Origin and insertion of MCL
Medial epicondyle to tubercle of ulna
Elbow: origin and insertion of annular ligament
Radial notch of ulna to neck of radius
Elbow: origin and insertion of quadrate ligament
Radial notch of ulna to neck of radius
What are the bones in the hand
Scaphoid
Lunate
Triquetrum
Psiform
Trapezium
Trapezoid
Capitate
Hamate
What are the joints in the hand
Carpometacarpal joint
Metacarpophlangeal joint
Interphalangeal joint
What are the other structures for the elbow, wrist and hand
Olecran bursa
Interosseus membrane
What is the olecranon bursa
It is a sac overlying the olecranon process of the elbow beneath the skin, it reduces the friction on movement between the skin, tendons, ligaments and bones
What is the interosseus membrane
Thick fibrous sheet of connective tissue that spans between the ulna and radius
What are the main joints in the elbow
Humeroradial joint
Humeroulnar joint
