Overview
Fractures of the scapular body encompass various types, including transverse fractures inferior to the scapular spine, often mistakenly termed "floating shoulder" cases, and incomplete avulsion fractures of the scapular spine due to violent muscle contractions 12.Diagnosis
Key Diagnostic Criteria:
- Transverse fractures involving the infraspinous part of the scapular body, distinct from true scapular neck fractures that separate the glenoid from the body 1.
- Incomplete avulsion fractures localized medial to the spinoglenoid notch, often associated with pseudo-rupture symptoms mimicking rotator cuff tears 2.
Recommended Tests:
- Radiographic imaging (X-ray, CT, MRI) to confirm fracture type and extent 12.
- Clinical examination focusing on tenderness over the scapular spine and rotator cuff integrity 2.Management
First-Line Treatments:
- Immobilization with a sling or figure-of-eight bandage for transverse fractures 1.
- Pain management with NSAIDs for symptomatic relief 1.
Adjunctive Treatments:
- Physical therapy focusing on shoulder mobilization and strengthening post-immobilization 1.
- Surgical intervention considered for displaced fractures or those causing significant functional impairment 1.Special Populations
Pediatrics: Not addressed in provided abstracts.
Elderly: Not specifically addressed in provided abstracts.
Comorbidities: Management considerations for comorbidities like osteoporosis or neuromuscular disorders are not detailed in the abstracts 12.Key Recommendations
Avoid Mislabeling Fractures: Do not use the term "fracture of neck inferior to scapula spine" for transverse fractures of the infraspinous part of the scapular body, as it does not accurately describe the anatomical separation 1 (Evidence: Strong).
Thorough Imaging Essential: Confirm diagnosis with appropriate imaging (X-ray, CT, MRI) to differentiate between true scapular neck fractures and infraspinous body fractures 12 (Evidence: Moderate).
Clinical Examination Crucial: Perform detailed clinical examination, particularly assessing tenderness over the scapular spine, to prevent misdiagnosis of incomplete avulsion fractures 2 (Evidence: Weak).References
