[CME-Sonography 106: Subacromial Bursa - A Myth]

Area of Science:

• Orthopedic medicine
• Diagnostic imaging
• Musculoskeletal system

Background:

• Bursitis is a common clinical finding affecting various joints.
• Shoulder pain is frequently attributed to subacromial bursitis in clinical practice.
• The existence and diagnostic criteria for subacromial bursitis are debated.

Approach:

• This review critically examines the concept of subacromial bursitis.
• It analyzes sonographic findings and clinical presentations of shoulder pain.
• The aim is to differentiate true subacromial bursitis from other shoulder pathologies.

Key Points:

• Subacromial bursitis is frequently diagnosed but its pathological basis is questionable.
• Sonography can visualize the subacromial space, but findings may be misinterpreted.
• Alternative diagnoses should be considered for shoulder pain previously attributed to subacromial bursitis.

Conclusions:

• The diagnosis of subacromial bursitis may represent a diagnostic myth.
• A nuanced approach to shoulder pain evaluation is necessary.
• Further research is needed to clarify the etiology of shoulder pain in the subacromial region.
