Nursemaid's elbow is a radial head subluxation caused by axial traction on the 
extended arm while the forearm is pronated, allowing for slippage of the radial 
head. A 2-year-old boy presented with pain, swelling and reduced range of 
movement of the right elbow for 4 days. The mother noted that the child was 
moving the right upper limb less often and there was tenderness over the right 
elbow. X-ray of the right elbow showed subluxation of the elbow joint with no 
obvious fracture. A trial of conservative management was decided upon and the 
patient was placed on a right elbow backslab with the right forearm in a supine 
position. On follow-up, there was no swelling, tenderness or neurological 
deficit noted. A repeate x-ray revealed normal findings.
