Initial Management of Type 3 Acromion with Bursitis
Begin with conservative management including NSAIDs, physical therapy, and activity modification, as Type 3 acromion morphology alone does not mandate surgical intervention and should be treated based on the underlying bursitis pathology rather than acromial shape. 1, 2
Conservative Treatment Approach
First-Line Pharmacological Management
- Start with NSAIDs for symptomatic relief of bursitis, such as naproxen 500 mg twice daily or 250 mg every 6-8 hours, with initial doses not exceeding 1250 mg/day 3
- Consider acetaminophen or tramadol as alternatives in patients with cardiovascular risk factors or contraindications to NSAIDs 4
- Avoid routine corticosteroid injections initially, as the American Academy of Orthopaedic Surgeons notes conflicting evidence regarding efficacy of subacromial corticosteroid injections 1
Non-Pharmacological Interventions
- Implement physical therapy focusing on scapular strengthening, postural reeducation, and core strength endurance 5
- Apply local modalities including ice, rest, and activity modification 5, 6
- Consider nasal saline irrigation analogy applies here as local measures for symptom control 3
Role of Corticosteroid Injection
If conservative measures fail after 6-8 weeks, consider subacromial corticosteroid injection with triamcinolone acetonide 40-80 mg (for larger joints/spaces), though evidence shows this is more effective than alternatives but has conflicting support for routine use 1, 7, 8
- Triamcinolone acetonide demonstrates superior efficacy compared to newer biologics like rilonacept for subacromial bursitis 8
- Injection should be performed using strict aseptic technique with the suspension shaken before use to ensure uniformity 7
Imaging Considerations
- Obtain standard shoulder radiographs including AP views and suprascapular outlet or Rockwood view to confirm Type 3 acromion morphology 1, 2
- Do not obtain advanced imaging unless conservative treatment fails or complications are suspected 4, 2
- MRI without contrast or ultrasound may be appropriate for evaluating soft tissue pathology if radiographs are noncontributory and symptoms persist 1, 2
Critical Decision Point: Surgery is NOT Indicated Initially
The presence of Type 3 acromion does not justify acromioplasty, as Level II randomized studies demonstrate no significant difference in outcomes between rotator cuff repair with versus without acromioplasty 1, 2
- Studies of 47-80 patients show no differences in ASES, Constant-Murley, or DASH scores regardless of acromioplasty 1
- Adequate conservative treatment trial (minimum 6-8 weeks) should precede any surgical consideration 1
Treatment Timeline and Reassessment
- Continue conservative management for 6-8 weeks minimum before considering escalation 4, 5
- If symptoms improve, continue initial treatments until complete resolution 4
- If no improvement occurs, reassess for alternative diagnoses or complications before proceeding to injection or surgical consultation 5
Common Pitfalls to Avoid
- Do not perform routine acromioplasty based solely on Type 3 morphology - this represents outdated practice not supported by current evidence 1, 2
- Avoid premature corticosteroid injection without adequate trial of NSAIDs and physical therapy 1
- Do not obtain MRI or advanced imaging as initial diagnostic step - radiographs are sufficient initially 4, 2
- Ensure proper injection technique if corticosteroids are used, as improper administration can cause subcutaneous fat atrophy 7
