Pinned ankle fracture. Coloured frontal X-ray of the ankle bones of a patient with pinned ankle fractures. The malleolus (bony projection at the end of a bone) of both lower leg bones have been fractured and then pinned back together. The fibula (left) is the thinner of the two lower leg bones, and has had a plate as well as screws used to hold it together. The pins and plates hold the bone fragments in position while they heal. The tibia (right) is the thicker of the two lower leg bones. The bones at bottom are part of the ankle bones. Staples are seen in the surrounding tissue, showing where the skin was stapled back together following the bone-pinning operation. This is the patient's right ankle.
