Three bones come together at the elbow. One bone makes the upper arm and 2 make the lower arm. One of the lower arm bones may slip out of place at the elbow. This is called a pulled elbow. It is a common elbow injury in toddlers and preschoolers.
A pulled elbow can be easily treated. It does not lead to long-term problems.

Ligaments help to keep your bones in place. These ligaments are loose in young children. Bones are also not fully formed in young children. These factors make it easier for the bones to slip out of place.
An pulled elbow happens with a sudden jerk, tug, or blow to the elbow. It is most likely when the arm is extended and twisted. In children, even a small amount of force may cause the injury.
These types of injuries are most common in children 1-6 years of age.
Actions that may increase the risk of dislocation include:
Children that have had a pulled elbow are more likely to dislocate their elbow again.
Symptoms may include:
Your doctor will ask about your child’s symptoms. A physical exam will be done.
The diagnosis will most likely be made during the physical exam.
Your doctor may also look for signs of broken bone such as swelling and tenderness. An x-ray may be done if this is suspected.
The doctor will be able to move the bone back in place.
For some children the pain will go away once the bone is back in place. A child may also be able to easily move their arm within a few minutes.
For other children, it may take a few tries to move the bone back into position. Treatment may also be delayed in younger children with mild pain. In these cases, discomfort may continue after the bone is moved back into place. The doctor may advise:
Some dislocations can be prevented. To help reduce your child’s chance of a partial dislocation:
