Flashcards in TEST 3: Elbow, Wrist, Hand OSCE Deck (39)
-axis of humerus to the axis of the forearm
-allows forearms and hands to clear hips when swinging during walking
-on average, larger in adult women due to wider hips and narrower shoulders
how does ulnar ABduction affect the carrying angle?
how does ulnar Adduction adduct the carrying angle?
know the locations of the following and how you could palpate them:
-wrist flexors and pronators
-wrist extensors and supinators
what muscles are involved in flexion of the elbow?
biceps, brachialis, brachioradialis
what muscles are involved in extension of the elbow?
what muscles are involved in supination of the elbow?
what muscles are involved in pronation of the elbow?
pronator teres, pronator quadratus
ROM of flexion of elbow
ROM of extension of elbow
0 to -5 deg
ROM of supination of elbow
ROM of pronation of elbow
how do we ran muscle strength?
-0 to 5
-5 being the muscle contracts normally against full resistance
-4 being muscle strength is reduced but can still move against resistance
-3 being muscle strength is further reduced such that the joint can be moved only against gravity, no resistance
-2 being muscle can move only if resistance of gravity is removed
-1 being only a trace or flicker of movement is seen or felt in the muscle, or fasciculations are observed in the muscle
-0 being no movement is observed in the muscle
what are the principles governing elbow joint?
1. SD is found in minor gliding motions of the joint, not the major motions
2. SD of the ulnohumeral joint is usually primary and SD of the radioulnar joints is usually secondary
3. impaired fcn of any joint of the arm produces compensatory changes in all other joints (can cause secondary SD)
what motion is ulnar abduction coupled with and what do we need to do to get that motion?
-coupled with wrist adduction (ulnar deviation)
-valgus--push medially on lateral elbow and laterally at wrist
what motion is ulnar adduction coupled with and what do we need to do to get that motion?
-coupled with wrist abduction (radial deviation)
-varus--push laterally on medial elbow and medially at wrist
what is an ulnar ABduction SD?
ease of motion toward ABduction, restriction of ADduction
what is an ulnar ADduction SD?
ease of motion toward ADduction, restriction of motion to ABduction
what positions should you test ulnar abduction and adduction in?
both in extension and supination
what is radial head anterior glide coupled with?
coupled with supination
what is radial head posterior glide coupled with?
coupled with pronation
what is an anterior radial head SD?
ease of motion toward anterior glide and supination
what is an posterior radial head SD?
ease of motion toward posterior glide and pronation
what should we palpate at the wrist and hand?
-distal radius and ulna
-radial styloid process
-anatomic "snuff box"
-MCP, PIP, DIP
ROM of flexion of the wrist
ROM of extension of the wrist
ROM of adduction of the wrist (ulnar deviation)
ROM of abduction of the wrist (radial deviation)
what is wrist flexion coupled with?
coupled dorsal/posterior carpal glide
