Shoulder Lab Flashcards
Shoulder Anatomy:
Which 3 Bones?
3 True Synovial Joints
2 Functional Joints
2 Accessory Joints
- Clavicle, Humerus, Scapula (Coracoid & Acromion)
- Glenohumeral, Sternoclavicular, Acromioclavicular
- Scapulothoracic (Scapula on Thoracic cage) & Suprahumeral
- Costosternal & Costovertebral

Scapular Motion Testing
Downward Rotation
Upward Rotation
Scapulo-Humeral Rhythm
Turning on A/P axis so scapula rotates in frontal plane to tilt glenoid fossa downward
Turning on A/P axis so scapula rotates in frontal plane to tilt glenoid fossa upward
1:2 Ratio of scapular motion to humeral motion (180 degrees abduction = 60 scapular + 120 humeral)
Scapular Motion Testing:
Elevation
Depression
Abduction (Protraction)
Adduction (Retraction)
Backward Tilt
Forward Tilt
Superior glide in vertical direction along Coronal Plane
Inferior glide in vertical direction along Coronal Plane
Away from spine, combined with lateral tilt around thorax
Moving closer to the spine
Turning on horizontal axis so posterior surface faces downward and inferior angle is anterior
Turning on horizontal axis so posterior surface faces upward and inferior angle protrudes

SC Abduction
SC Adduction
SC Flexion
SC Extension
Scapular Elevation leads to Inferior movement of SC joint
Shoulder Depression leads to Superior motion of SC joint
Protraction of scapula leads to Posterior glide of clavicle at SC joint
Retraction of scapula leads to Anterior glide of clavicle at SC joint

Assess glides springing inferiorly on distal clavicle
Distal end of clavicle
Look for shifted clavicle: Superior/Inferior, Step-Off
Clavicle on Acromion for Step-Off or Tenderness/TTA
Cross-Arm Adduction Test (Positive = Pain or Increased TTA)
Resistant to springing inferiorly (Clavicle Superior); Presence of springing inferiorly (Clavicle Inferior); (Ant/Post) - Springing Ant/Post
