What is the evaluation and management of a patient with a history of trauma to the rotator cuff, presenting with swelling?

Evaluation and Management of Traumatic Rotator Cuff Injuries with Swelling

For patients with a history of trauma to the rotator cuff presenting with swelling, initial evaluation should include radiographs followed by MRI, with early surgical repair recommended for full-thickness tears within 3 weeks of injury for optimal outcomes. 1, 2, 3

Initial Evaluation

Imaging

1. First-line imaging: Plain radiographs 2

   • Anteroposterior (AP) view in neutral position
   • Grashey view (AP with 30-45° posterior oblique)
   • Axillary lateral or scapular Y view
   • To rule out fractures and other bony abnormalities

2. Second-line imaging: MRI 2, 3

   • Gold standard for evaluating soft tissue pathology
   • Standard MRI without contrast is highly effective (rated 7/9)
   • MR arthrography may be considered for better visualization of labral tears

Physical Examination

• Inspection: 2

  • Shoulder contour
  • Muscle atrophy
  • Scapular winging
  • Visible swelling

• Palpation: 2

  • Tenderness at acromioclavicular joint, sternoclavicular joint, greater tuberosity, bicipital groove, and coracoid process
  • Assessment of swelling location and characteristics

• Range of motion: 2

  • Active and passive motion in all planes
  • Forward flexion, abduction, external rotation, and internal rotation
  • Compare with contralateral side
  • Note pain arcs and limitations

• Strength testing: 2

  • Rotator cuff muscles (supraspinatus, infraspinatus/teres minor, subscapularis)
  • Deltoid and biceps
  • Grade on a 0-5 scale

Management Algorithm

1. Partial-Thickness Tears

• Conservative management: 1, 3, 4, 5

  • Rest and activity modification
  • Ice application for swelling reduction
  • NSAIDs for pain and inflammation
  • Physical therapy with rotator cuff and scapular stabilization exercises

• If conservative treatment fails after 3-6 months: 2

  • Consider surgical consultation for débridement versus repair of high-grade partial tears

2. Full-Thickness Tears

• Early surgical repair is recommended, especially for: 1, 3

  • Young, active patients
  • Traumatic tears with acute onset
  • Better outcomes shown when repaired within 3 weeks of injury

• Timing of surgery: 1

  • Evidence suggests that patients repaired within 3 weeks of injury had better results than those repaired after 3 weeks
  • At minimum, repair should be performed within 4 months of injury for optimal outcomes

3. Non-Surgical Management (if surgery is delayed or contraindicated)

• Pain management: 1, 6, 5

  • NSAIDs for pain and inflammation
  • Consider single corticosteroid injection (caution with multiple injections)
  • Multimodal pain management approaches

• Physical therapy: 1, 2

  • Rotator cuff strengthening exercises
  • Scapular stabilization
  • Range of motion exercises (avoiding aggressive passive movements)
  • Manual therapy techniques

Important Considerations and Pitfalls

Corticosteroid Injections

• Caution with multiple injections: Multiple steroid injections may compromise the integrity of the rotator cuff, potentially affecting subsequent repair 1
• Single injection may be appropriate for short-term pain relief while awaiting definitive treatment 4, 6

Timing of Surgery

• Critical factor: Early repair (within 3 weeks) shows better outcomes for traumatic tears 1
• Acute rotator cuff injuries are relatively uncommon, representing <10% of rotator cuff repairs 1
• Delayed repair (beyond 3 weeks) may result in less favorable outcomes 1

Age Considerations

• Increasing age: Negatively correlates with healing and strength outcomes after rotator cuff repair 1
• Rotator cuff tears are rare under age 40 unless accompanied by acute trauma 5

Supervised vs. Unsupervised Exercise

• Supervised physical therapy is more appropriate than unsupervised home exercise for post-repair rehabilitation 1

Follow-up Schedule

• Initial evaluation with radiographs at 1-2 weeks
• Clinical assessment and possible radiographs at 6 weeks
• Assessment for progress of rehabilitation at 3 months
• Long-term follow-up at 6-12 months to evaluate for late complications 2

By following this structured approach to evaluation and management, patients with traumatic rotator cuff injuries presenting with swelling can receive optimal care with the best chance for favorable outcomes in terms of morbidity, mortality, and quality of life.
