Upper Extremity Conditions Flashcards
peripheral nerve involvement of the spinal accessory nerve would show as:
inability to abduct past 90*, pain in shoulder on abduction
peripheral nerve involvement of long thoracic nerve would show as
pain with fully flexing an extended arm, inability to fully flex an extended arm, winging at 90* flexion
peripheral nerve involvement of the supra scapular nerve would show as
increased pain with forward flexion, shoulder weakness, pain increases with abduction and cervical rotation to the opposite side
peripheral nerve involvement of the axillary nerve signs:
inability to abduct the arm with neutral rotation
capsular pattern of the shoulder
ER>ABD>IR
open packed position of the glenohumeral joint
55 ABD, 30 horizontal rotation neutral rotation
closed packed position of the glenohumeral joint
Full ABD and ER
convex concave rule of GH joint
convex humerus on a concave glenoid
SLAP type 1
fraying of the labrum, no detachment
SLAP type 2
superior labrum is completely torn off the glenoid
SLAP type 2a
tear of superior labrum is only anterior to midpoint of biceps
SLAP type 2b
tear of the superior labrum is only posterior tot the midpoint of the biceps tendon
SLAP type 2c
tear of superior labrum both anterior and posterior
SLAP type 3
bucket handle: biceps intact
SLAP type 4
labrum and LHB torn
Bankhart lesion is
a tear of the rim below the middle of the gleaned socket - mostly will occur with dislocations
hill sachs lesion
compression of the posterolateral head of the humerus
common compression sites of TOS
scalene triangle, between clavicle and first rib, between pec minor and thoracic wall, superior thoracic outlet
osteochondrosis of humeral capitellum
bone fragment becomes detached caused by repetitive compressive forces between radial head and capitulum; occurs in kids 12-15
Panner’s disease
a localized avascular necrosis of capitellum ; 10 and younger
DE quervians tenosynovitis is inflammation of what tendons
extensor pollicis brevis and abductor pollicis longus
difference between colles and smith fracture
radius dispalces dorsally/posteriorly in colles and volarly in smith’s.
Dupuytren’s contracture
contracture of palmar fascia usually effecting MCP and PIP of 4th and 5th fingers in on diabetic individuals. Affects 3rd and 4th in diabetics
Ape hand is a dysfunction of what nerve
median: inability to abduct the thumb away from the rest of the hand
