Shoulder Arthrodesis (Shoulder Fusion Surgery)

Shoulder arthrodesis is a salvage surgery that permanently fuses the shoulder joint to eliminate pain when all other treatment options have failed - it's reserved for severe end-stage shoulder problems like failed shoulder replacements with massive bone loss, irreparable rotator cuff tears causing pseudoparalysis in young patients, or chronic shoulder infections, achieving 80-90% pain relief but eliminating shoulder movement and forcing reliance on scapular (shoulder blade) motion for arm positioning.

📖What is Shoulder Arthrodesis (Shoulder Fusion Surgery)?

Shoulder arthrodesis is a salvage surgery that permanently fuses the shoulder joint to eliminate pain when all other treatment options have failed - it's reserved for severe end-stage shoulder problems like failed shoulder replacements with massive bone loss, irreparable rotator cuff tears causing pseudoparalysis in young patients, or chronic shoulder infections, achieving 80-90% pain relief but eliminating shoulder movement and forcing reliance on scapular (shoulder blade) motion for arm positioning.

đŸ”ŦWhat Causes It?

  • Failed shoulder replacement (arthroplasty) with massive bone loss making revision impossible
  • Irreparable massive rotator cuff tear with pseudoparalysis in young manual laborers (reverse shoulder not ideal long-term)
  • Brachial plexus injury causing flail shoulder (nerve damage eliminating muscle function)
  • Chronic shoulder infection destroying joint with insufficient bone for arthroplasty
  • Severe post-traumatic arthritis with bone loss in young patients unsuitable for joint replacement

âš ī¸Risk Factors

â„šī¸

You may be at higher risk if:

  • Previous failed shoulder arthroplasty requiring multiple revision surgeries
  • Chronic shoulder infections not responding to debridement and antibiotics
  • Massive irreparable rotator cuff tears in young heavy manual workers
  • Brachial plexus injuries (motorcycle accidents, birth trauma)
  • Severe shoulder trauma with bone loss

đŸ›Ąī¸Prevention

  • ✓Optimize initial shoulder surgeries to reduce failure risk (experienced surgeons, appropriate implant selection)
  • ✓Prompt treatment of shoulder infections to prevent chronic bone destruction
  • ✓Careful selection of patients for shoulder arthroplasty (some patients better served with alternative treatments)
  • ✓Avoid high-risk activities after shoulder replacement (heavy lifting, high-impact sports increasing failure risk)
