Elbow/wrist/hand Flashcards
Primary flexors of elbow joint
Brachialis
Biceps
Secondary flexors of elbow joint
Brachioradialis
Supinator
Primary extensor of elbow joint
Triceps m
Secondary extensor of elbow joint
Anconeus
Normal carrying angles for elbow in males vs females
Males: 5-10 degrees
Females: 10-15 degrees
Supination is coupled to what motion at the proximal radial head?
Supination = anterior proximal radial head
Pronation is coupled to what motion at the proximal radial head?
Pronation = posterior proximal radial head
Falling supine would likely result in what SD of the radial head?
Supinated (anterior) radial head
Primary flexors of the wrist
Flexor carpi radialis
Flexor carpi ulnaris
Primary extensors of the wrist
Extensor carpi radialis longus m
Extensor carpi radialis brevis m
Extensor carpi ulnaris m
Primary supinators of the wrist
Biceps m
Supinator m
Secondary supinator of the wrist
Brachioradialis
Primary pronators of the wrist
Pronator teres
Pronator quadratus
Secondary pronator of the wrist
Flexor carpi radialis m
Tendons of what muscles make up the anatomic snuffbox?
EPL
EPB & APL
Wrist flexion = _______ glide of proximal carpal bones
Posterior/dorsal
[wrist extension = anterior/ventral glide of proximal carpal bones]
Ulnar deviation = ________
Adduction
Action of adductor pollicis brevis
Flexion of the thumb
Tx for nursemaid’s elbow
Place thumb on anterior side of radial head
Apply gentle longitudinal traction
Supinate fully
Flex elbow
Principles governing elbow joint:
- SD is found in the ______ gliding motions of the joint, not the opposite
- SD of the ________ joint is usually primary and SD of the ______ joint is usually secondary
- Impaired funcion of any joint of the arm produces compensatory changes in nearby/distal joints (may cause secondary SD)
Minor
Ulnohumeral; radioulnar
What is the reference point for naming dysfunctions of the elbow?
Distal ulna
