  1. Hawkins’ test forward flexes the arm to 90°and
    applies maximum internal rotation to the flexed
    elbow. If one supplies downward pressure at the
    elbow while the patient resists, the sensitivity of
    the exam increases (Hawkins and Kennedy, 1980;
    Valadie et al, 2000).


RADIOGRAPHIC EXAMINATION



  • Standard radiographs include an anteroposteior
    (AP), axillary, and supraspinatus outlet view. These
    views will allow you to determine if there is degen-
    erative joint disease in the AC or glenohumeral
    joints, spurring from the acromion or calcification
    within the tendon (calcific tendonitis). Chronic rota-
    tor cuff tears will often result in superior humeral
    head migration secondary to atrophy of the lower
    rotator cuff. A true scapular AP view will allow
    better examination of the glenoid and internal and
    external rotation view will allow better assessment
    of the humeral head for defects or impression frac-
    tures.

  • Special radiographs are indicated in certain condi-
    tions. A supraspinatus outlet view is often obtained to
    evaluate the morphology of the acromion in rotator
    cuff or impingement syndrome. A West Point view is
    helpful in evaluating the anterior glenoid for bony
    deficiency in cases of instability.

  • MRI is an excellent tool for determining rotator cuff
    pathology, but is often overused and/or obtained too
    soon.

  • Certain signal characteristics are indicative of full
    tears versus partial tears versus AC arthritis. A mag-
    netic resonance imaging (MRI) can determine labral
    pathology (Bankart lesions, or SLAP tears), bursitis,
    acromial morphology, and articular cartilage condi-
    tion. More details about MRI for upper extremity
    injuries can be found in chapter 43.

  • An MRI does not need to be obtained immediately if
    the patient has full ROM and only complains of pain
    and weakness. These patients can be started on the
    nonoperative treatment described below and the vast
    majority will improve. An MRI can be obtained after
    the next visit if the patient’s symptoms have not
    resolved with therapy.


NONOPERATIVE TREATMENT



  • Rotator cuff strengthening is essential for recovery
    and many patients improve after surgical intervention
    because they finally commit themselves to the reha-
    bilitation.

    • The focus of rehabilitation should be to reduce
      inflammation (usually bursal), restore motion, and
      strengthen muscles to help stabilize the scapula and
      humerus. Therapists will start with anti-inflammatory
      modalities, work on ROM and begin periscapular
      strengthening to stabilize the scapula (Jobe and
      Moynes, 1982; Wilk and Arrigo, 1993).

    • Nonsteroidal anti-inflammatory drugs (NSAIDs) are
      usually helpful to help decrease the bursitis and
      reduce the pain. They are not curative in themselves,
      but decrease pain so the patient can do therapy. In rare
      instances, the pain is severe enough for a short course
      of narcotics.
      •A subacromial injection can be performed as a diag-
      nostic test or as part of the treatment plan. When the
      Neer sign is positive, an injection is made into the
      subacromial space using a local anesthetic. The
      patient is retested after 3–5 min and the Neer test is
      positive if the pain is relieved. Many physicians who
      are certain of their diagnosis will proceed with a ther-
      apeutic injection of 2–3 cc of an injectable corticos-
      teroid at the same time. Others will inject a second
      time if the initial injection relieves the patient’s symp-
      toms.

    • If there is a diagnostic dilemma between whether the
      AC joint is the cause of pain or the bursa, injections
      can be performed in one location and then the second
      to determine the source. The subacromial injection
      should be done first because with AC pathology—the
      capsule is often disrupted and an AC injection is likely
      to go into the bursa as well. The reader is referred to
      chapter 72 on injections for more information.

    • Once the pain is reduced and the ROM restored, more
      aggressive strengthening exercises are instituted.
      Internal and external rotation exercises using rubber
      tubing or resistance bands are very useful, and the
      patient progresses to heavier tubing, as they get
      stronger. Supine or lateral decubitus exercises with
      small weights are also started at this time.

    • Core strengthening exercises to help stabilize the
      scapula are also instituted. These exercises are very
      important and often neglected. Simple exercises such
      as squeezing the shoulder blades together or scapular
      rows are often effective. Progress is monitored by
      observing normal scapulothoracic motion with eleva-
      tion. If scapular winging is severe or fails to improve
      with treatment, further workup for other etiologies
      such as trapezius or long thoracic nerve palsy should
      occur.

    • Deltoid strengthening, to include isolated training of
      all three parts of the deltoid.

    • Strengthening of the supraspinatus is not instituted
      immediately because it will aggravate symptoms.
      Supraspinatus strengthening should be started when
