Case Discussion Bony anatomy The ankle is a synovial joint composed of the distal tibia and fibula as they articulate with the talus. The distal tibia and fibula articulate with each other at the distal tibiofibular joint which is more commonly referred to as the tibiofibular syndesmosis (or simply the syndesmosis).

Correct side (right vs. left) Views In the United Kingdom, two views of the ankle joint are routinely performed: Mortise view: this is a modified anteroposterior (AP) view of the ankle in 10-20° internal rotation so that the medial and lateral malleoli are in the same horizontal plane and joint visualisation is optimised Lateral view An ankle x-ray, also known as ankle series or ankle radiograph, is a set of two x-rays of the ankle joint. It is performed to look for evidence of injury (or pathology) affecting the ankle, often after trauma. Reference article This is a summary article. For more information, you can read a more in-depth reference article: ankle series. Summary Introduction The ankle joint is one of the most commonly injured joints and the most common type of fracture to be treated by orthopedic surgeons. [1] The estimated incidence of ankle fractures is approximately 187 per 100,000 people per year. [2] Stress view.

Ankle radiographs are performed for a variety of indications including 2-6 : ankle trauma bony tenderness at the posterior edge or the tip of the lateral malleolus bony tenderness at the posterior edge or the tip medial malleolus inability to weight bear non-traumatic ankle pain Projections Standard projections AP Indications This projection aids in evaluating fractures, dislocations and joint effusions surrounding the ankle joint, and helps to assess the severity of a calcaneal fracture by measuring the Böhler angle and Gissane angle. Patient position patient is in a lateral recumbent position on the table The true anteroposterior view of the ankle is often performed in the setting of ankle trauma and suspected ankle fractures in addition to the lateral and mortise views of the ankle. Other indications include: assessment of fragment position and implants in postoperative follow up evaluation of fracture healing Ankle Fracture Mechanism and Radiography. Robin Smithuis.

Management decisions are based on the interpretation of the AP and lateral X-rays. In this article we will focus on:

There are three main sets of ligaments: Medial: deltoid ligament Lateral: posterior talofibular, anterior talofibular and calcaneofibular ligaments Syndesmotic ligament From Radiology Masterclass Ankle views An x-ray of the ankle will have three views - AP, mortise, and lateral. Ankle anatomy - Normal AP 'mortise' The weight-bearing portion is formed by the tibial plafond and the talar dome The joint extends into the 'lateral gutter' ( 1) and the 'medial gutter' ( 2) The joint is evenly spaced throughout Ankle anatomy - Normal Lateral Hover on/off image to show/hide findings

A standard ankle x-ray series consists of the AP, lateral and a 15 degree internal oblique (aka Mortise View) [2]. Figure 1: Example of a normal ankle series. Case courtesy of Andrew Murphy, Radiopaedia.org If questionable osseous findings noted on x-ray, consider CT to evaluate further. If x-rays are negative, consider MRI to search for occult osseous, ligament, or tendon injuries.. Note the normal fat density anterior to the ankle joint on the lateral view of the normal ankle ( Figure 11-1 C ).
