Test 1 material #5 Flashcards
when one bursa is connected, the others usually are why?
because they are connected
lubricating sac
bursae
shoulder complex is derived embryonically from __- __ except the A-C joint
C5-C8
A-C Joint is derived embryonically from
C4
Sympathetic nerve supply of shoulder comes from
T2-T8
heavy book bag and or improperly fitted crutches can cause
prolonged compression injury to axillary nerve
Atrophy in hand muscles comes from
klumke’s palsey
brachial artery supplies
both heads of the biceps
Arteries of the rotator cuff
throracoacromial artery
subscapular artery
suprahumoral artery
infraspinatus nerve supply
suprascapular nerve
infraspinatus blood supply
suprascapular artery
supraspinatus blood supply
suprascapular artery
supraspinatus nerve supply
suprascapular nerve
subscapularis nerve supply
subscapular nerve
subscapularis blood supply
subscapular artery
Teres minor nerve supply
axillary nerve
Teres minor blood supply
circumflex scapular and humoral arteries
GH joint at 90 degrees abduction and full external rotation
closed packed
GH joint at 55 degrees abduction and 30 degrees horizontal adduction
open packed
joint where scapula moves and suspends upper limbs
AC joint
AC joint motions
rotation, spin and rotation, glide (A-P)
Diarthrodial
AC joint nerves
suprascapular, lateral pectoral, axillary nerves
Blood supply to AC joint
thoracoacromial and supra scapular arteries
scapulohumeral rhythm
2:1 GH to scapula movement
reverse scapulohumeral rhythm
more scapular movement than GH usually associated with Frozen shoulder
Aka for frozen shoulder
adhesive capsulitis
Cubital fossa (6)
biceps brachii median nerve radial nerve brachial artery Median cubital vein
avulsion of medial epicondyle due to values overload
little league’s elbow aka
comes from pulled hand in pronated position
radial head slips out of annular ligament (subluxation)
2-5 y/o
pulled elbow/nurse’s maid syndrome
direct chronic blows to elbow
patient presents elbow in semi flexion
swollen olecranon blocks extension
olecranon bursitis aka student’s elbow/miner’s elbow
fracture at proximal to middle 1/3 of ulna
ant. radial head dislocation
Montegga fracture
increased carrying angle
cubital valgus
cubital values can lead to
lateral condylar fracture
parts of the MCL
Anterior bundle
transverse bundle
posterior bundle
anterior bundle (2)
Anterior band
posterior band
anterior band of anterior bundle
strongest/stiffest (like my D) stabilized against valgus
posterior band of anterior bundle
taught at 55 degrees flexion secondary to anterior band against valgus
Transverse band of anterior bundle AKA
Cooper’s ligament connects ulna to ulna and gives little stability to ulna
Post. band of anterior bundle
thickening of post elbow capsule provides protection against valgus
MCL and all associated parts protect from
valgus
MCL Aka
Ulnar collateral ligament
