In nursemaid's elbow, radiographs are rarely necessary to diagnose. Which option is correct about radiographic use?

• A. They are always necessary
• B. They should be done if the child is older than 5 years
• C. They are rarely necessary
• D. They should be done before reduction

Answer: (C)

Nursemaid's elbow is diagnosed clinically, not with routine imaging. The typical scenario—a young child with sudden arm pain after pulling on the forearm, holding the elbow slightly flexed and refusing to use the arm, and no obvious deformity—points to radial head subluxation. Because these features are classic, radiographs do not usually change management and are not required before attempting reduction. Imaging would expose the child to radiation and can delay treatment in an otherwise straightforward case. Radiographs are appropriate only when there are red flags or uncertainty: unusual age (older than the typical range), suspicion of another fracture or injury, swelling or neurovascular concerns, or persistent pain after reduction. In those situations, X-rays help rule out alternative diagnoses.
