Talus fracture fixation
Fixation of talus fractures is surgery that repairs fractures of the talus, a small, important bone that sits between the heel bone (calcaneus) and the two bones (tibia and fibula) of the lower leg. The tibia and fibula fit on top of and around the sides of the talus bone, forming the ankle joint. The talus serves a vital function as a connector between your foot, leg and body, as it helps transfer weight and pressure across the ankle joint as well as below the ankle and in the midfoot.
Relatively rare, talus fractures usually are caused by automobile accidents, falls from high places and snowboarding. The American Academy of Orthopaedic Surgeons (AAOS) reports that most broken talus injuries require surgery to restore stability to the ankle and avoid future complications.
Internal fixation is the most commonly used surgery for talus fractures. The term "fixation" refers to the use of screws, plates, pins or wires (known as metal instrumentation) to hold the bones in position as they heal.
Fixation of talus fracture surgery begins with at least one incision on the outside of the ankle to gain access to the broken talus. Your surgeon then realigns the broken talus bones (a process called reduction) and removes any bone fragments. Your surgeon might also replace the missing bone fragments with bone grafts to fill the gaps and help restore the structural integrity of the ankle joint.
After surgery, your foot and leg will be put in a cast for six to eight weeks to provide further protection while the bones heal. Approximately three months after surgery, your surgeon may let you begin putting weight on your foot again.
