CAMRT Radiography Practice Exam

In which position is the proximal tibiofibular articulation best demonstrated?

1. Medial oblique

2. Lateral oblique

3. AP

4. Lateral

The correct answer is: Medial oblique

The proximal tibiofibular articulation is best demonstrated in a medial oblique position, as this orientation allows for optimal visualization of the joint space between the tibia and fibula. In a medial oblique position, which typically involves placing the patient in a 45-degree angle with the affected limb internally rotated, the alignment of the tibia and fibula creates an unobstructed view of the proximal tibiofibular joint. This positioning effectively opens up the joint, reducing superimposition from surrounding structures and providing clearer delineation of anatomical details. The medial oblique also enables the radiographer to better assess any potential pathologies or injuries affecting the joint. In contrast, alternative positions such as the lateral oblique, AP, and lateral may not provide the same degree of clarity and detail for evaluating the proximal tibiofibular articulation. For instance, while a lateral position may show the bones aligned, it generally does not present the joint space effectively, as it is too focused on the lateral aspect. The AP view could adequately present the overall structure but lacks the specific emphasis on the articulation needed for thorough examination. The lateral oblique, while useful for other angles, also does not enhance the visualization of this particular joint as effectively as the medial
