What is it?
Sudden traction on a young child’s arm can displace the ligament around the radial head; this differs from a complete elbow dislocation.
Symptoms and important signs
The child suddenly stops using the arm; major swelling or deformity is unusual.
How is it assessed?
History and examination; X-ray if atypical or fracture is suspected.
Care and treatment options
Reduction by a trained clinician; lift children under the arms rather than by the wrists.
When to seek help
Swelling, bruising, deformity or continued non-use after reduction needs reassessment.
