Question
**Case Study: Diagnosing Nursemaid's Elbow**

**Scenario:**
A four-year-old child presents to urgent care with a painful right elbow. Her mother reports that the pain started acutely about an hour ago, after pulling her daughter up by the wrist to prevent her from running in front of a car backing out of a parking space.

**Clinical Question:**
Upon examination, which of the following findings is most indicative of a nursemaid's elbow (subluxation of the annular ligament due to sudden longitudinal traction applied to the hand)?

**Possible Answers:**

- **A:** Full active ROM (Range of Motion) at the right elbow
- **B:** Tenderness just distal to the medial epicondyle
- **C:** Redness and swelling over the olecranon
- **D:** Holding arm in slight flexion upon inspection

**Explanation:**
The patient's history and clinical signs suggest a diagnosis of nursemaid's elbow, a common injury in young children usually caused by a sudden pull on an extended arm. The most characteristic finding is that the child typically holds the arm in slight flexion and refuses to use it, which aligns with option D.
