•Shoulder pain: a common
complaint in primary care
•2
nd
only to knee pain for specialist
referrals
•Most common causes in adults (peak
ages 40-60)
•Subacromial impingement syndrome
•Rotator cuff problems

•Shoulder: 8-13% of all
athletic injuries

ball and tee”

multiple factors

25% of humeral head
surface in contact with
glenoid.

FINDING PROBABLE DIAGNOSIS
Scapular winging, trauma, recent viral illness Serratus anterior or trapezius dysfunction
Seizure and inability to passively or actively rotate affected arm
externally
Posterior shoulder dislocation
Supraspinatus/infraspinatus wasting Rotator cuff tear; suprascapular nerve entrapment
Pain radiating below elbow; decreased cervical range of motionCervical disc disease
Shoulder pain in throwing athletes; anterior glenohumeral joint pain
and impingement
Glenohumeral joint instability
Pain or “clunking” sound with overhead motion Labral disorder
Nighttime shoulder pain Impingement
Generalized ligamentous laxity Multidirectional instability

aspects of opposite scapula
Loss of range of motion: rotator cuff
problem
