Shoulder 101 …and Then Some Evan D. Ellis MD Rebound Orthopaedics and Sports Medicine
Why Shoulder 101? Multiple studies: High percentage of visits to see PCP are for musculoskeletal pain Multiple studies: High percentage of visits to see PCP are for musculoskeletal pain 2 studies * : Large gap in PCP confidence in evaluating and treating musculoskeletal injuries 2 studies * : Large gap in PCP confidence in evaluating and treating musculoskeletal injuries Studies in both a rural and tertiary academic setting Studies in both a rural and tertiary academic setting *Lynch et al JBJS AM 2006 and AJO 2005
