Shoulder Anatomy
4
• Inspection
• Anterior• Posterior
• Bilateral
Shoulder Physical Exam
5
• Palpation
• AC joint• Subacromial space• Musculature• Scapula• Head of biceps tendon
Shoulder Physical Exam
6
• ROM
• Flexion• Raise arm (180 degrees)
• Extension (50 degrees)• Lower arm
Shoulder Physical Exam
7
• ROM
• Abduction• Arms horizontal
• Adduction• Arms medial

Shoulder Physical Exam

• ROM• Internal Rotation, External Rotation

Shoulder Physical Exam
10
• 67 yo male presents to clinic for an IV• He has shoulder pain
• What further questions do you want to ask him?
• What is on your DDx?
11
• Occurs less often than LE joints since not weight-bearing
• Aspect of worst pain often anterior• Morning stiffness• Pain on ROM• May have prior hx of trauma
Shoulder Osteoarthritis
12
• PE• Anterior and/or posterior ttp• Crepitus• Decreased ROM• Cross-Arm test for A-C OA
• Dx/Tx• X-ray• NSAIDs, ice, PT, injection, shoulder
replacement
Shoulder Osteoarthritis
13
14
• Impingement• RC cuff becomes inflamed as it is compressed
between the humerus & choracoacromial arch
• Pain over ant/lat aspect of shoulder• Some radiation down arm• Worse with overhead activity
• Empty can (Jobe’s test)• Neer’s sign
Rotator Cuff Pathologies
15
• Tendonitis• Essentially a continuum with impingement
• Painful ROM
Rotator Cuff Pathologies
16
• Supraspinatus• Abduction/flexion• Jobe’s or Empty Can test, Neer’s, etc• Drop Arm (tear)
• Infraspinatus• External rotation• Infraspinatus test
Rotator Cuff Pathologies
17
• Teres minor• External rotation• Hornblower’s/Patte test
• Subscapularis• Internal rotation• Gerber or Lift off test
Rotator Cuff Pathologies
18
• Partial/full tear • Can be due to acute injury in younger patients • Can be traumatic or degenerative in older patients• Pain, weakness esp with overhead activity and often at
night• Most common tear is supraspinatus
• Drop arm test
• Consider MRI• Caution with repeated injections
Rotator Cuff Pathologies
19
• Clinically similar to RC tendonitis• Anterior shoulder pain
• TTP in subacromial space
Subacromial bursitis
20
• AKA Frozen Shoulder
• Trouble with ADLs• Often painful initially then less so if ROM
regained
Adhesive capsulitis
21
• PE• Decreased active and passive ROM (<50% of
normal side)• May have diffuse ttp
• Dx/Tx• X-ray• NSAIDs, moist heat, PT, • Consider injection
Adhesive capsulitis
22
• Pain with activity
• Point tenderness at insertion site
Biceps Tendonitis
23
24
https://meded.ucsd.edu/clinicalmed/upper_biceps_rupture.jpg
• Rupture usually involves long head of the biceps • Often minimal trauma required• Sudden pain, sometimes an audible snap
• Often visible and/or palpable bulge• Usually non-operative, except if pt very active
and/or distal rupture
Biceps Rupture
25
• 67 yo male presents to clinic for an IV• He has no particular complaints• On routine exam you find the following:
• Pain on abduction• Palpable and visible deformity• Played football in high school
26
Dx = Acromialclavicular Injury
27
Dx = Acromialclavicular Injury
28
• If acute• X-ray• Type I & II -> sling, NSAIDs, ice• Type III -> controversial so case dependent• Types IV-VI -> operative repair
• If chronic• Becomes degenerative & managed as such
