A 4 yo M presents to Urgent Care with R shoulder pain after a fall off his bed. Father denies any head trauma or other injury. On exam, he has decreased ROM at the R shoulder and tenderness and ecchymosis along the distal/mid clavicle. Neurovascular exam is normal. An xray is done and shown below. What's the diagnosis? (scroll down for answer)
Answer: Acute fracture of the R mid clavicle with minimal inferior displacement
- Etiology:
- Most commonly caused by fall onto shoulder (85%), less commonly fall onto outstretched hand
- Presentation:
- patients typically present w/ guarding/favoring of affected arm
- may see gross deformity, focal tenderness, swelling or ecchymosis of the clavicle
- pain is worse w/ ROM
- Diagnosis:
- often diagnosed by history and physical exam
- plain radiography
- Allman System used to classify clavicle fractures based on location:
- Group I- middle third clavicle fracture (80%)
- Group II- distal third clavicle fracture (10-15%)
- Group III- proximal third clavicle fracture (5%)
- ED management:
- must perform neurovascular exam due to close proximity to brachial plexus and subclavian vessels
- non-displaced (or minimally displaced) fractures are often managed non-operatively
- operative management determined by location, stability and degree of displacement
- orthopedic referral
- emergent surgical consult for airway or great vessel involvement
