| 68 year-old woman with total ankle prosthesis failure with loosening of tibial and talar component shown by bony lucency about the components and medial polyethylene liner wearing. |
69 year-old woman recovering from triple malleolar fracture with associated two medial malleolus fixation screws, two syndesmotic screws, and a fibular plate and screws. There is an interference screw in the subtarsal joint near the sinus tarsi from prior subtalar joint fusion. A fixation screw is present at the base of the 5th metatarsal from an old metatarsal shaft (Jones) fracture. |
Fixed bearing porous coated total ankle prosthesis with partially conforming articulation. There is a distal tibiofibular syndesmosis with two syndesmotic screws. Figure is from Taljanovic, 2005. |

67 year-old man with complex distal tibia and fibular fracture and delayed union in the tibia fracture. There are fracture fixation plates and screws in the tibia and fibula, suture anchors at the lateral malleolus, and a ghost track in the calcaneus.
