What is the recommended treatment for a patient with early hypertrophic changes at the glenohumeral joint, presenting with chronic pain and popping in the right shoulder?

Treatment for Early Hypertrophic Changes at the Glenohumeral Joint

The recommended first-line treatment for early hypertrophic changes at the glenohumeral joint with chronic pain and popping is a structured physical therapy program focused on strengthening the rotator cuff and periscapular muscles, combined with NSAIDs for pain management. 1

Initial Assessment and Conservative Management

Physical Therapy (First-Line Treatment)

• Begin with a structured program targeting:
  • Rotator cuff strengthening exercises
  • Periscapular muscle strengthening
  • Gentle stretching to maintain/improve range of motion
  • Gradual progression of active range of motion exercises
• Focus on external rotation and abduction movements which are commonly limited

Pain Management

• NSAIDs (acetaminophen or ibuprofen) for pain relief and anti-inflammatory effects 1
• Apply ice after activity to reduce inflammation
• Activity modification to avoid aggravating movements (especially overhead activities)

Second-Line Interventions

If symptoms persist after 4-6 weeks of conservative management:

Injectable Therapies

• Injectable viscosupplementation is an option (Grade C recommendation by the American Academy of Orthopaedic Surgeons) 2
• Subacromial corticosteroid injections may be beneficial if there is associated subacromial pathology 1
• The evidence for corticosteroid injections specifically for glenohumeral osteoarthritis is insufficient according to guidelines 1

Imaging Follow-up

• If symptoms worsen or fail to improve with conservative treatment, additional imaging may be warranted:
  • MRI without contrast (rated 7/9 for appropriateness) to evaluate associated soft tissue pathology 2, 1
  • MR arthrography (rated 9/9 for appropriateness) if labral pathology is suspected 2

Advanced Treatment Options

For patients with persistent symptoms despite 3-6 months of conservative treatment:

Surgical Considerations

• Total shoulder arthroplasty (TSA) is recommended over hemiarthroplasty for advanced glenohumeral osteoarthritis 2
• Important considerations before surgical intervention:
  • Evaluate rotator cuff integrity (TSA should not be performed in patients with irreparable rotator cuff tears) 2
  • Consider patient age (younger patients have higher risk of prosthetic loosening) 1
  • Surgeon experience is important (avoid surgeons who perform fewer than two shoulder arthroplasties per year) 2

Monitoring and Follow-up

• Regular follow-up every 4-6 weeks during conservative management
• Monitor for:
  • Changes in pain levels and functional ability
  • Development of mechanical symptoms (catching, locking)
  • Progressive limitation in range of motion

Caution and Pitfalls

• Early hypertrophic changes often progress over time, requiring adjustment of treatment plans
• Avoid aggressive stretching which may exacerbate symptoms
• Be aware that radiographic findings of early osteoarthritis may not correlate with symptom severity
• Total shoulder arthroplasty should be avoided in patients with irreparable rotator cuff tears 2

This treatment approach follows a stepwise algorithm from conservative measures to more invasive options, with the goal of reducing pain, improving function, and potentially slowing disease progression.
