Study Notes

Shoulder Pain Overview

Common causes include local issues and referred pain from nerve root compression (C4, C5) and myocardial ischemia.
Shoulder pain ranks second in prevalence among the general population, following lower back pain.

Shoulder Impingement Syndrome (SIS)

SIS refers to the compression of structures around the glenohumeral joint during shoulder elevation, causing persistent pain and dysfunction.
Key risk factors for SIS include:
- Repetitive overhead activities in sports (e.g., swimming, tennis, weightlifting).
- Overhead work tasks (e.g., painting, stocking shelves).
- Increasing age, joint instability, scapular instability, and upper extremity inflexibility.

Shoulder Anatomy

Consists of five articulations: glenohumeral joint, coracoacromial arch, sternoclavicular joint, acromioclavicular joint, and scapulothoracic articulation.
The rotator cuff comprises four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) that stabilize the humeral head in the glenoid socket.

Pathophysiology of SIS

Caused primarily by the repetitive compression of the supraspinatus tendon under the coracoacromial arch.
The ‘impingement position’ (abduction, slight flexion, and internal rotation) exacerbates compression of the rotator cuff.
The critical area of reduced vascularity in the supraspinatus tendon is about 1 cm proximal to its insertion, leading to potential tears and chronic issues.

Clinical Presentation

Patients typically experience pain with overhead activities, localized to the deltoid area or lateral arm.
Pain may worsen at night or when lying on the affected shoulder.
Physical examination includes:
- Atrophy inspection, glenohumeral range of motion evaluation, and specialized tests like Neer and Hawkins-Kennedy.
- Tenderness is felt at the anterior edge of the acromion.

Diagnostic Imaging

Plain radiographs are not essential for SIS diagnosis but can rule out other conditions.
Musculoskeletal ultrasound effectively evaluates tendon and muscle lesions.
MRI is suitable for assessing rotator cuff pathologies beyond SIS.

Diagnosis

Primarily clinical, based on history and examination findings with supportive imaging.

Differential Diagnosis

Rotator cuff tears commonly present with weakness and are linked to chronic SIS.
Adhesive capsulitis (frozen shoulder) involves restricted motion and pain, often post-injury or in diabetics.

Treatment Options

Cryotherapy helps reduce inflammation and provides pain relief.
Rest from aggravating activities is crucial.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may be used in short courses for pain management.
Physical therapy is the primary treatment and may preclude the need for surgery.
Subacromial glucocorticoid injection is recommended for persistent pain after conservative treatment.
Referral for orthopedic evaluation is warranted if no improvement occurs after three months of conservative management.
