Nursemaid’s elbow is also known as a “pulled elbow” or “partial dislocation of the radial head”. It is the most common traumatic elbow injury of children accounting for 15-27% of all elbow injuries in children younger than 10 years of age. The average age of incidence is 2-4 years old. Usually this occurs when the parent, walking with the child, pulls on the child’s arm to help them up onto a curb or pulls them from a sitting position. The radial head pops out of joint or the annular ligament becomes entrapped in the joint. The x-rays are usually normal. The child will hold the arm in a protected position and not use the upper extremity. They hold the elbow flexed (bent) with the palm turned downward. The initial pain usually subsides and they will return to play. Younger children may hold the arm limp. The child needs to have the radial head popped back into place. This is usually done at the doctor’s office or emergency room. Afterwards, the child should begin using the arm fairly quickly. Casts are not routinely used in order to allow the bones to resume normal function, but casts may be necessary to relieve pain if there have been multiple episodes.
