The best single X‑ray view for the ankle is the mortise view, which—by internally rotating the foot about 15–20°—opens the ankle mortise to show joint space, medial and lateral malleoli, and syndesmosis. Clinically, a three‑view series (AP, mortise, lateral) is recommended to maximize detection of fractures and joint displacement. It also improves assessment of talar alignment and subtle widening.

An oblique view in x‑ray imaging is an angled projection obtained by rotating the patient or the beam so structures are imaged between the standard frontal (AP) and side (lateral) views. This reveals anatomy and fractures hidden on AP/lateral images by reducing overlap, improving visualization of joints, ribs, spine, shoulders, and extremities for better assessment of alignment and bony detail.

An oblique x‑ray of the right foot is a radiographic projection taken with the foot rotated about 30–45° to separate overlapping bones. It gives a clear view of metatarsals, phalanges, tarsals (notably cuboid and sinus tarsi) and joint spaces. It’s used to detect fractures, dislocations, arthritis, bone lesions or foreign bodies. Positioning is simple, requires no special preparation and involves a low radiation dose.

A right ankle x-ray typically includes three views: anteroposterior (AP) to assess the tibia, fibula and joint space; lateral to evaluate the talus, calcaneus and alignment; and a mortise (internally rotated AP/oblique) view to open the ankle mortise and better visualize the syndesmosis and joint surfaces. These views improve detection of fractures and joint injuries.

No. An oblique fracture is a diagonal break across a bone shaft. Mortise refers to the ankle mortise (the socket formed by the tibia and fibula) or the mortise radiographic view used to evaluate ankle joint congruence and syndesmotic injury. They are different entities with distinct diagnosis, management, and treatment approaches.

The three standard foot X‑ray views are: anteroposterior (AP or dorsoplantar) — shows forefoot and midfoot alignment; lateral — shows sagittal profile, arch and displacement; and oblique (usually 30° medial oblique) — highlights metatarsals, tarsometatarsal joints and lateral structures. Weight‑bearing films are often obtained to assess alignment and joint space under load.
