What technique is used to treat radial head subluxation?

The technique used to treat radial head subluxation, commonly referred to as "nursemaid's elbow," involves forearm hyperpronation. This procedure effectively reduces the subluxation by utilizing a specific motion that allows the radius to return to its normal position in the elbow joint.

Forearm hyperpronation works by rotating the forearm in such a way that the radial head is realigned properly within the annular ligament, thereby alleviating the entrapment that causes pain and limited movement. This method is quick, effective, and can often be performed in a clinical setting with minimal discomfort for the child. It's essential for practitioners to be familiar with this technique due to the common occurrence of this injury in pediatric populations, particularly in young children who may be pulled or yanked by their arms.

Other treatments, like elevation of the arm, cold compress application, or active movement therapy, do not address the mechanical cause of the subluxation itself and therefore would not be effective in resolving the acute issue.
