An X-ray of the ankle is a safe and painless test to visualise the bones of the ankle and the soft tissues (skin and muscles) surrounding it using small amount of radiation. The ankle consists of three bones – tibia and fibula (bones of the lower leg), and talus (one of the foot bones) and two joints – ankle joint (where tibia, fibula and talus meet) and syndesmosis joint (joint between tibia and fibula). The image is recorded on a special X-ray film. The X-ray image is black and white. Dense structures such as the bones, appear white and softer body tissues, such as the skin and muscles appear darker. The actual exposure time to radiation is usually less than a second, although the overall test may take 15-20 minutes.
