Dr. Morton explains the anatomy visible in foot X-rays, focusing on the DP, oblique, and lateral views. The DP view highlights the tibia, fibula, and metatarsals, while the oblique view shows the calcaneus and cuneiforms. The lateral view reveals the tibiotalar joint and sinus tarsi. Key structures like the Liz Franc joint and sesamoid bones are discussed, emphasizing their clinical importance.

Which bones are visible in the DP view of a foot X-ray?

• Tibia, fibula, talus, calcaneus, navicular, cuneiforms, and metatarsals

• Femur, patella, tibia, fibula

• Scapula, clavicle, humerus

• Radius, ulna, carpals

What is the clinical significance of the 5th metatarsal in foot X-rays?

• It is not visible in any standard X-ray view

• It is the only bone visible in the lateral view

• It is prone to fractures that can affect the Lisfranc joint complex

• It is the longest bone in the foot

What is the Lisfranc joint complex composed of?

• The bases of the five metatarsals and the three cuneiforms

• The phalanges and sesamoid bones

• The tibia and fibula

• The talus and calcaneus

In the oblique view of a foot X-ray, which bone is prominently visible?

• Femur

• Humerus

• Scapula

• Calcaneus

What is the angle of rotation for the oblique view of a foot X-ray?

• 10 to 20 degrees

• 30 to 40 degrees

• 50 to 60 degrees

• 70 to 80 degrees

What is the sinus tarsi, as seen in the lateral view of a foot X-ray?

• A joint between the tibia and fibula

• A cavity in the femur

• A space between the talus and calcaneus

• A ligament in the knee

What feature of the foot is visible in a good lateral view X-ray?

• The longitudinal arch

• The patellar tendon

• The plantar fascia

• The Achilles tendon
