In a suspected subluxation of the radial head, what symptom would NOT typically be present?

In a suspected subluxation of the radial head, one would typically expect certain physical manifestations that indicate discomfort and limited mobility. The symptom of being able to wrap arms around a parent for comfort suggests a degree of normal pain tolerance and mobility, which is not characteristic of a radial head subluxation.

When a child has a radial head subluxation, they usually exhibit a posture where their elbow is held flexed and pronated as a protective mechanism against the pain and discomfort caused by the injury. This position limits their ability to move the elbow freely. Swelling and tenderness are also common symptoms associated with this type of injury, as these responses are typical of traumatic injuries where inflammation and sensitivity result from the displacement of the bone.

Therefore, the ability to comfortably wrap their arms around a parent indicates a comfort level that is uncharacteristic of the distress typically seen in cases of radial head subluxation, where pain and restricted mobility generally lead to a more guarded posture.
