Shoulder Girdle Flashcards
Weightlifter’s Shoulder
distal clavicular osteolysis, is a painful inflammation at the end of the clavicle, at the acromioclavicular (AC) joint
- Breakdown/Resorption (Osyeolysis)
Rotator Cuff Tear
most often in tendon
(possibly with avulsion)
- supraspinatus
Shoulder girdle joints
Glenohumeral Joint
Scapulothoracic Joint
Rotator cuff
Glenohumeral Joint contribute to
o Deltoid o Pec major o Coracobrachialis (and biceps brachii) o Latissimus dorsi o Teres major o Rotator cuff
Scapulothroacic Joint contribute to
o Trapezius o Rhomboid major & minor o Levator scapula o Pec minor o Serratus anterior
Rotator Cuff contribute to
o Subscapularis (anterior)
o Teres major
o Infraspinatus (posterior)
o Supraspinatus
Scapula Stabilisation
Most muscles acting on humerus originate on the scapula – except pec major and latissimus dorsi
Scapula Mobility
Scapulohumeral ‘rhythm’ – during abduction, 2/3 of ROM from shoulder joint, 1/3 from
• Abduction or forward flexion
Shoulder impingement
Involves tendonitis (with or without inflammation) of rotator cuff muscles as they pass through the subacromial space (i.e. under acromion)
Shoulder bursitis
The impingement process may also affect the subacromial bursa - fluid filled sac that cushions and reduces friction between tissues
Rotator cuff tear
Most common in supraspinatus
