7/23/2013 Diagnosis Rotator cuff tear more likely if… • Older patient A. Adhesive capsulitis • Traumatic mechanism B. Rotator cuff tear • Weak on exam C. Impingement syndrome D. Glenohumeral joint osteoarthritis Treatment Rotator cuff disease spectrum • Stage I: < 25 y/o. Bursitis A. Order MRI, confirm tear, refer for arthroscopic RTC repair • Stage II: 25 ‐ 40 y/o. Tendinitis and fibrosis of B. Repeat trial of physical therapy, f/u 3 months. rotator cuff • Stage III: > 40 y/o. Partial to complete tearing C. NSAIDs and activity modification, f/u 3 months of rotator cuff D. Subacromial injection, f/u 3 months 10

7/23/2013 AP shoulder Rotator cuff tear algorithm • If weak on testing of rotator cuff  order xrays and MRI  if (+) rotator cuff tear  refer. • Greater likelihood tear if >40 y/o • Surgical outcomes better if cuff tears fixed earlier than later – Smaller tear – Less fatty infiltration – Less muscle atrophy – Less retraction Reduced acromiohumeral interval Saupe N, et al. AJR, 2006. Differential diagnosis Case #3 traumatic shoulder injury • 30 y/o RHD man fell off bike 9 months ago, • AC joint separation injured R shoulder • Labral tear • Went to PT but continues to have pain • Rotator cuff tear • Anterior shoulder • Shoulder dislocation • Only feels pain if moves shoulder in certain • Fracture directions quickly – Humerus or clavicle • Does not wake him from sleep at night 11
