Which projection of the femur is contraindicated for patients with suspected fracture or destructive disease?

1. AP projection

2. Lateral projection

3. Cross-table lateral projection

4. AP oblique projection

The correct answer is: Lateral projection

The lateral projection of the femur is contraindicated for patients with suspected fractures or destructive diseases due to the positioning and handling that may be required to obtain this view. In a lateral projection, the technical procedure often necessitates manipulation of the limb, which can lead to further displacement of a fracture or exacerbate an underlying inflammatory process associated with destructive diseases. When a patient has a suspected fracture, maintaining the integrity of the fracture site is crucial to prevent additional injury. The lateral view requires the femur to be positioned in a manner that could cause movement or stress on the area of concern, thereby increasing the risk of complications. If there's a destructive disease such as osteolysis or a pathological fracture, the lateral projection may also worsen the condition by increasing pain or causing further damage. In contrast, other projections, such as the AP projection or cross-table lateral projection, may not require as much manipulation or movement of the affected limb, making them safer options for imaging in patients with suspected fractures or underlying disease processes. The AP oblique projection can also be performed with less risk, as it can be adjusted to minimize stress on the fracture site or affected area. Thus, the lateral projection poses a higher risk, warranting its contraindication in these specific clinical scenarios
