Lower Extremities Practice Test 2026 – Complete Exam Preparation

The main idea is to obtain a true lateral view of the lower leg so the tibia and fibula can be evaluated without rotation or overlap—that means the leg must be in a lateral position and the knee should be seen in profile.

Lying on the affected side with the knee in profile places the leg in a true lateral orientation, minimizing rotation and ensuring the tibia and fibula shafts are superimposed. This setup keeps the knee and ankle joints included in the image and helps visualize any fractures, displacements, or deformities accurately. Standing or seated positions would produce an AP or oblique view rather than a true lateral, which isn’t ideal for assessing the alignment of the tibia and fibula. Lying on the unaffected side would introduce unwanted rotation, making the lateral view less reliable.
