Nursemaid’s Elbow or Radial Head Subluxation is a common physical disorder affecting children in the age group of 1-7 years. The injury is also known as Pulled Elbow and Toddler’s Elbow. As the bones and joints of children are tender and still in a formative stage, there is an increased likelihood of dislocations. The elbow joint is made up of the upper arm bone, humerus, and two lower arm bones; ulna and radius. These are held together by the ligaments, muscles and tendons. The elbow further comprises into two joints:
Humeroulnar joint, where the humerus meets the ulna and enables the elbow to bend
Radiocapitellar joint, the meeting point of radius and humerus that enables the forearm to rotate In Nursemaid’s Elbow, the radiocapitellar joint gets dislocated. It is a temporary injury and may not lead to any long term damage to the joint. As the child grows, the ligaments and muscles become stronger as well as keep the joint stable, thereby, reducing the chances of suffering the injury.
