Upper Extremity Anatomy Tests Flashcards
4 Greek terms for upper extremity inspection
Rumor =. Redness
Tumor = mass
Dollar = pain
Calor =. Heat
4 joints of the shoulder
Acromioclavicular
Scapulothoracic
Glenohumeral
Sternoclavicular
Acromion
Long flat curved process of scapula that forms the AC joint and is the site of the middle deltoid attachment
Coracoid process
Deep scapular projection that serves as the origin of the short head of biceps and insertion of pectoralis minor and coracobrachialis
3 acromion types
Flat (least likely to cause impingement)
Curved
Beaked (most likely to cause impingement)
Impingement is the supraspinatus muscle w/ overhead activities
3 heads of deltoid origins
Clavicle
AC joint
Scapular spine
- pain along the insertion of the deltoid (lateral humerus) is most indicative of a rotator cuff tear*
Neutral shoulder ROM
Flexion = 150-170
Extension = 60
External rotation = 60
Internal rotation (in front of body) = 70
Internal rotation (behind back) = 95
Horizontal internal rotation vs horizontal external rotation degrees
Internal = 70 degrees
External = 90 degrees
- horizontal implies arms are abducted 90 degrees*
Abduction vs adduction degrees
Abduction = 180
Adduction = 20-40
Scapulohumeral motion
For every 30 degrees of shoulder abduction
20 degrees = humeral abduction
10 degrees = scapular rotation
Specific names of scapular rotation
“Up and down” =. A-P axis movement through AC joint
“Scapular winging” =. Vertical axis movement through AC joint
“Scapular tipping” = horizontal axis through the AC joint
(AC joint does abduction and both internal/external rotation)
Neutral plane of the scapula
30-45 degrees forward in coronal plane
Movements of the clavicle
Anterior/posterior
Superior/inferior
External/internal rotation
Boa’s sign
Pain in right shoulder/upper back is refereed pain from right abdominal organs (liver/gallbladder/ duodenum/ etc.)
Kehr’s sign
Pain in left shoulder/upper back is indicative of referred pain from the left abdominal organs
(Spleen, stomach and possibly renal damage)
Joints of the elbow
Humero-ulnar
(Flexion/extension)
Humero-radial
(Pronation/supination)
Proximal radio-ulnar
(Pronation/supination)
