What are the indications for total shoulder arthroplasty? What are the differences between total shoulder arthroplasty and reverse shoulder arthroplasty? What are the 4 S of the shoulder? Use patient age as an aid to diagnosis Become consistent with a shoulder physical exam. What are the indications for total shoulder arthroplasty? What are the differences between total shoulder arthroplasty and reverse shoulder arthroplasty? What does the future of shoulder arthroplasty look like? 2
Strength Stability Flexibility Strength Stability Flexibility 3
Minimally constrained ball-and-socket joint Mobility Stability Static Stabilizers Bone/Cartilage Dynamic Stabilizers Rotator cuff Scapula muscles Shoulder ~33% constraint Hip >50% constraint 4
4 S s Stiffness Strength Stability Smoothness Stiffness: Limited active and passive ROM Patient complaints of inability to reach Often normal x-rays Strength Weak on exam Normal x-rays Unable to lift overhead or with elbow away from body Get MRI to evaluate rotator cuff Stability Shoulder moves, dislocation, ER reduction, Laxity vs Instability Smoothness Crepitus/grinding Check ROM, painful Abnormal x-rays 5

Was there any trauma? Does this shoulder pain keep you up at night? Does it hurt to move your neck? Do you have any numbness or tingling down into your hand? Order of importance: Nerves Motion Strength/Stability Neck Hand/wrist/elbow Sensation Strength Active ROM Look for atrophy Passive ROM Standing Supine Tenderness Strength 7

No active shoulder motion for 4 weeks, all planes No active internal rotation for 6 weeks Keep wound dry Icing 3 times/day for 20 minutes Pendulums 3x/day x 30 seconds 2-6 weeks AAROM All planes limit ER to 30 With cane progress to finger ladder/wall climbs/pulley system Pulleys for home exercise program 8 weeks Full PROM, ER to 60, Advance to full AROM (ER 60 ); Add stretching in forward elevation (if lacking). Never stretch in abduction/er. Mean complication rate: 2-5% Infection (0.7%) Glenoid Loosening (6%) Does not always correlate with symptoms Radiolucent lines (84%) Subscap failure Fracture (0.6-2.3%) Nerve Injury (1-4.3%) Rotator Cuff Tear (1.3%) Instability 21
