What causes a radial head fracture?

A radial head fracture is commonly associated with a fall onto the wrist. When an individual falls, the force of the impact travels up the arm and can create enough stress at the elbow joint to cause a fracture of the radial head. This type of injury typically occurs when the person tries to break the fall with their outstretched hand, which transmits the force through the forearm and into the elbow region, resulting in injury to the radial head.

Falls are a frequent mechanism of injury for this type of fracture, particularly in the elderly or in athletes who may engage in sports that pose a risk of falling. Understanding the biomechanics involved helps healthcare providers assess the injury correctly and implement appropriate management strategies for the patient.
