10/19/2012 PRINCIPLES OF Shoulder Issues EXAMINING THE Second most common musculoskeletal complaint SHOULDER Hmm..What was #1? Difficult joint to examine Greg Bennett, PT DSc Why is this? Excel Physical Therapy Multidirectional range of motion- Marymount University UNIQUE! How many “joints”? Shoulder injury can affect nearly every sport and many daily activities Objectives EXAMINATION GOALS Global enough to rule out referred syndromes Review pertinent anatomy and/or associated pathologies. Specific focus on pathologic tissues as the diagnosis becomes clear. Discuss common pathologies Develop a prognosis that is realistic for the diagnosis, i.e. is therapy the appropriate intervention. Discuss historical Establish a treatment program according to the clues to diagnosis diagnostic with continuous modification to meet change. Select cases Physical exam in small group discussions Bony Anatomy Anterior Radiographic Anatomy 1 10/19/2012 Anatomy Anatomy Glenohumeral joint Glenohumeral joint • “Ball and socket” vs • Passive stability “Golf ball and tee” Joint conformity • Very mobile Glenoid labrum (50%) • Price: instability Joint capsule • 45% of all dislocations Ligaments • Joint stability depends Bony restraints on multiple factors Anatomy Anatomy Rotator Cuff Muscles Muscles • Deltoid • Trapezius * • Rhomboids * • S – Supraspinatus • Levator scapulae * • I – Infraspinatus • Rotator cuff • Teres major • T - Teres minor • Biceps • Pectoralis muscles * • S- Supscapularis • Serratus anterior * * Scapular stabilizers Anatomy Anatomy Bursae Neurologic • Subacromial • Nerve roots (Subdeltoid) • Brachial plexus • Subscapular • Peripheral nerves 2 10/19/2012 Anatomy “If we agree on everything, one of Coordinated us is unnecessary” shoulder motion • Glenohumeral motion • Acromioclavicular motion • Sternoclavicular motion • Scapulothoracic Scapular-humeral rhythm motion EXAMINATION GOALS CURRENT SYMPTOMS 1.ESTABLISH OR Swelling???

Where do things go wrong?? Dislocations and Separations Dislocations and Separations Arthritis can happen at these joints, too… Dislocations and separations are protected by both “static” and “dynamic” stabilizers… 7 10/19/2012 Bony Anatomy Glenohumeral Joint “Static Stabilizers” Shallow (“golf ball sitting on a tee”) • Inherently unstable (maximizes ROM) Static stabilizers • glenohumeral ligaments, glenoid labrum and capsule Dynamic stabilizers • Predominantly rotator cuff muscles • Also scapular stabilizers Trapezius, leavator scapulae, serratus anterior, rhomboids What goes wrong… Superior Shoulder Suspensory Besides separations and dislocations??
