54 Cards in this Set

  • Front
  • Back
List movements in the shoulder complex
Flexion / Extension
Ab / Adduction
Internal / External rotation
Horizontal Flexion/ Extension
List the major articulations associated with the shoulder complex
sternoclavicular joint
acromioclavicular joint
glenohumeral joint
scapulothoracic joint
Method for evaluating shoulder complex injuries
glenohumeral ligaments
What causes clavicular fractures?
mode of injury is usually compressive, can be direct blow
indentifying for a clavicular fracture
look for "step-off" deformity most common in the middle 1/3 of clavicle
describe a step-off deformity
in the clavicle, usually medial end rides up due to SCM spasm, lateral end rides down due to weight of shoulder complex
treatment of a clavicular fracture
brace with a sling or strap
heal time is usually 6-8 weeks
watch for signs of radial nerve compression
types of radial nerve compression
immediate- at injury
delayed onset - compression from swelling
late onset - compression from new bone growth
most common shoulder dislocation
anterior dislocation
method of injury for anterior shoulder displacement
posterior blow, abduction w/ external rotation more common
method of injury for posterior shoulder displacement
internal rotation w/ adduction
labrum avulsion
enlarges glenoid fossa
treatment for shoulder dislocation
referral to MD for reduction and stabilization; began rehab as soon as possible
rehab for shoulder dislocation
include strength training for all muscles in & around shoulder
observations in shoulder dislocation
flattened deltoid, holding injured arm w/ good one
palpation for shoulder dislocation
feel for flattened deltoid
shoulder impingement causes
overuse injury, overhead motion
tissues involved in shoulder impingement
mechanical compression of supraspinatus tendon, subacromial bursa, long head of biceps tendon, under coracoacromial ligament
mechanism of injury for rotator cuff strain
high velocity rotation
muscles of the rotator cuff
supraspinatus infraspinatus teres minor subscapularis
partial thickness tear
less than 1 cm
how does an athlete develop shoulder bursitis
direct blow, overhead overuse injury
shoulder bursitis tissue
subacromial bursae
treatment for subacromial bursitis
treat swelling, refer for aspiration to avoid calcific bursitis
method of injury for SC ligament sprain
direct blow
observations in SC ligament sprain
might see step off deformity, watch for posterior displacement which can be fatal
more common SC ligament sprain
anterior displacement
treatment for SC ligament sprain
immobilize w/ brace
mechanism of injury for AC ligament sprain
blow to tip of shoulder
1st degree AC sprain
only AC involved, not complete
2nd degree AC sprain
complete AC tear, some CC
3rd degree AC sprain
complete AC tear, complete CC tear
4th, 5th, 6th degree AC sprain
major displacement of clavicle, requires surgery
development of biceps tendonitis/ tenosynovitis
overuse injury, overhead motion
palpation for biceps tenosynovitis
will feel crepitus
muscles involved in glenohumeral flexion
pectoralis major, anterior deltoid, biceps
muscles involved in glenohumeral extension
latissimus dorsi, teres major, posterior deltoid
muscles involved in glenohumeral abduction
supraspinatus, middle deltoid
muscles involved in glenohumeral adduction
pectoralis major, latissimus dorsi, teres major
muscles involved in glenohumeral medial rotation
pectoralis major, subscapularis, latissimus dorsi, teres major
muscles involved in glenohumeral lateral rotation
infraspinatus, teres major
muscles involved in scapular abduction & upward rotation
serratus anterior
muscles involved in scapular elevation
trapezius, levator scapula
muscles involved in scapular adduction
middle trapezius & rhomboid major
muscles involved in scapular depression & adduction
lower trapezius
muscles involved in scapular adduction & downward rotation
rhomboid major, rhomboid minor
muscles attaching axial skeleton to humerus
latissimus dorsi, pectoralis major
muscles attaching scapula to humerus
deltoid, teres major, coracobrachialis, rotator cuff
muscles attaching axial skeleton to scapula
levator scapula, trapezius, rhomboids, serratus anterior & posterior
movements of supraspinatus
abducts humerus, stabilize in glenoid cavity
movements of infraspinatus
laterally rotate & adduct humerus, stabilize in glenoid cavity
movements of teres minor
laterally rotate & adduct humerus, stabilize in glenoid cavity
movements of subscapularis
medially rotate humerus, stabilize in glenoid cavity
