A patient with a right hip injury is transported on a backboard. Which projections should be used to assess for a fractured hip?

The appropriate choice for assessing a fractured hip involves using the anteroposterior (AP) pelvis and a cross-table lateral hip projection. The AP pelvis provides a comprehensive view of both hips and the pelvic region, which is vital for evaluating the overall alignment and possible fractures in the hip area. This view can reveal any displacement or deformity associated with a fracture.

The cross-table lateral hip projection is critical because it allows visualization of the hip joint's anatomy and any fracture that may not be visible in the AP view. This lateral view is particularly useful for assessing the femoral neck, which is a common site of hip fractures.

The other options do not provide the optimal views needed for a thorough assessment of a hip injury. For example, lateral views of the femur or the knee may not adequately visualize the hip joint itself, missing critical information regarding potential fractures in that area.
