2 Evaluation and Treatment of the Painful Shoulder in the Primary Care Setting C. Christopher Smith, M.D. Associate Professor of Medicine Harvard Medical School Beth Israel Deaconess Medical Center

3 A 65-year-old woman with a history of type II DM presents for evaluation of new left shoulder pain. The pain is in her anterior and lateral shoulder and has gradually worsened over the last three weeks. It is dull and constant and keeps her up at night. She also notices marked discomfort when she combs her hair and cannot get sweaters from the top of her closet due to pain and weakness. She denies any trauma or prior injuries. She works as an investment banker.

4 The Painful Shoulder Recognize, diagnose and treat the most common cause of shoulder pain in the primary care setting Know how to differentiate it from other common causes of shoulder pain

5 The Painful Shoulder Anatomy History Differential based on patient s age and location of pain Physical exam maneuvers Initial treatment

13 So what is impingement syndrome?

14 Impingement Syndrome UpToDate, 2006

15 Typical History of Impingement Syndrome Any age, but risk increases with age Anterior or lateral shoulder pain Pain exacerbated by abduction and forward flexion Night pain common

16 Age and Shoulder Pain Young (< 30 y.o.) Dislocations/Instability of Glenohumeral Joint Separation of AC joint Overuse injury Less Young (30-60 y.o.) Impingement Syndrome Adhesive Capsulitis (especially in diabetics) Separation/Overuse as above Older (> 60 y.o.) Impingement Syndrome (non-traumatic tears) Adhesive Capsulitis Systemic Conditions (if bilateral, PMR, RA)

27 A 65-year-old woman with a history of type II DM presents for evaluation of new left shoulder pain. The pain is in her anterior and lateral shoulder and has gradually worsened over the last three weeks. It is dull and constant and keeps her up at night. She also notices marked discomfort when she combs her hair and cannot get her sweaters from the top of her closet due to pain and weakness. She denies any trauma or prior injuries. She works as an investment banker.

28 On inspection, her left humerus was riding slightly higher than her right. There was pain with palpation of the lateral subacromial space. ROM revealed pain with abduction and forward flexion; it was worse with active than passive movement. Positive empty can, Neer and Hawkins test.

29 What is the most appropriate initial treatment for this patient? A. NSAIDs alone B. NSAIDs with Physical Therapy C. Subacromial Steroid Injection with PT D. NSAIDs plus Steroid Injection E. Orthopedic consultation

30 What is the most appropriate initial treatment for this patient? A. NSAIDs alone B. NSAIDs with Physical Therapy C. Subacromial Steroid Injection with PT D. NSAIDs plus Steroid Injection E. Orthopedic consultation

31 Treatment Reduce offending activities Physical Therapy Aimed at improving mechanical dysfunction and shoulder motion NSAIDs or Subacromial injection Each is better than placebo Little long term difference No benefit in combination treatment White, J Rheumatol 1986 Petri, Arthritis Rheum 1987

33 You passively abduct the arm to 160 degrees and ask the patient to slowly lower her arm. At approximately 90 degrees, she is unable to continue to lower her arm due to weakness and she drops it to her side.

34 What is your diagnosis now? A. Bicipital Tendonitis B. Impingement Syndrome C. Adhesive Capsulitis (Frozen Shoulder) D. Tear of Supraspinatus Tendon E. Glenohumeral Joint Osteoarthritis

35 What is your diagnosis now? A. Bicipital Tendonitis B. Impingement Syndrome C. Adhesive Capsulitis (Frozen Shoulder) D. Tear of Supraspinatus Tendon E. Glenohumeral Joint Osteoarthritis

43 A 55-year-old male with IDDM, HTN and GERD presents with three months of worsening left lateral shoulder pain, which is worse at night. He reports pain with most any movement. Range of motion testing reveals pain and restricted movement in most directions. Symptoms are present with both passive and active movement.

44 Adhesive Capsulitis or Frozen Shoulder Thickening and contraction of the capsule surrounding the glenohumeral joint Insidious onset of pain Night pain Pain in deltoid, but no tenderness to palpation Pain and limited active and passive ROM Need AP X-ray of glenohumeral joint to rule out glenohumeral arthritis Treatment: Physical Therapy

45 What is the most significant risk factor for adhesive capsulitis? A. Diabetes B. Hypothyroidism C. Immobility D. AVN of glenohumeral head E. Reflex sympathetic dystrophy

47 46 year old male who moves furniture on the weekends and works as a handyman during the week, presents with right anterior shoulder pain. The pain began after a particularly heavy move, where he moved over a hundred boxes. No fever, chills, night sweats; no weakness or numbness. No prior injuries. He points to his anterior shoulder with one finger. He has a normal ROM and good strength and positive Yergason and Speed s tests.

48 What is your diagnosis? A. Bicipital Tendonitis B. Impingement Syndrome C. Adhesive Capsulitis (Frozen Shoulder) D. Tear of Supraspinatus Tendon E. Glenohumeral Joint Osteoarthritis

53 Speed s Test With elbow extended and hand supinated, palpate bicipital groove while patient attempts to forward flex shoulder 30 degrees against resistance Siegel, Am Fam Phys 1999

54 A 62 year old man was pulling a dead branch from a tree when he felt a sudden pain in his upper arm and heard an audible snap. Now, two weeks later, he has no pain and only minimal loss of strength. His exam is significant for the finding below. Which is the most likely diagnosis? A. Rotator cuff strain B. Proximal biceps tendon rupture C. Distal biceps tendon rupture D. Biceps tendonitis

56 Biceps Tendon Tear Proximal aspect of long head of biceps tendon After especially vigorous lifting Often in setting of chronically inflamed tendon Weakness of elbow flexion/supination Popeye Sign - bulge just proximal to antecubital fossa Risk Factors: Recurrent tendonitis Prior tear of rotator cuff or biceps Age > 50 RA

57 A proximal bicipital tendon tear can usually be treated conservatively, avoiding surgery. A. True B. False

58 A proximal bicipital tendon tear can usually be treated conservatively, avoiding surgery. A. True B. False

59 Summary Impingement syndrome most common cause of shoulder pain in the primary care setting Systematic approach to physical exam Range of Motion: pain with abduction, forward flexion; active > passive; painful arc Empty can, Neer, Hawkins tests to confirm Drop arm, internal and external lag signs indicate a complete tear - especially in patients > 60 years old

60 Summary Adhesive Capsulitis DM or Immobile shoulder Limited ROM in most planes Pain with both active passive ROM Biceps Tendonitis Associated with impingement syndrome Reproduced with Yergason and Speed s tests Popeye sign for biceps tendon tear

61 Summary A careful history and physical examination can correctly diagnose most common causes of shoulder pain. aspx?mediaid=
