Radial Head Subluxations
Key Points
Radial head subluxation, common among toddlers, can occur when a caregiver pulls a reluctant toddler forward or catches the toddler by the wrist during a fall—actions many caregivers do not remember. Most patients cannot describe their symptoms; the only indication of the injury may be unwillingness to move the affected arm. Diagnose based on history unless an alternate diagnosis is suspected. Treat by reducing the joint (using supination-flexion or hyperpronation); a subtle palpable pop or click is often detected when the radial head resumes its normal position.
