What positioning should a patient's leg be in for a Frog-Leg Lateral X-ray?

For a Frog-Leg Lateral X-ray, the patient's leg should be positioned in external rotation. This positioning is crucial as it allows the femoral necks to be parallel with the imaging receptor, providing a clear view of the acetabulum and allowing for proper visualization of the hip joint. The external rotation opens up the hip joint, making it easier to assess for any abnormalities such as fractures, dislocations, or developmental dysplasia.

In this position, the knees are placed together while the feet are positioned away from each other, resembling a frog's legs, which is how the name of the technique is derived. This orientation is essential for obtaining accurate diagnostic images. Therefore, external rotation is the required positioning for the Frog-Leg Lateral X-ray to ensure optimal imaging of the hip area.
