What Is An Ankle Fracture?
An ankle fracture is basically what we call as “broken ankle”. This means that one or more of the ankle bones are broken. There are two leg bones (the tibia and fibula) and one foot bone (talus) which forming the ankle. Most commonly, the bone that brakes is the bone on the outside of the ankle (the fibula).
As a result, ankle may create bone instability. Also the position of the ankle may shift. We call this state “fracture dislocation” ,which is more serious. Ankle fractures are generally the result of a trauma or injury.
First of all, we must divide fractures into two groups:
Stable Ankle Fractures: The ankle joint remains intact
Unstable Ankle Fractures: The ankle joint is dislocated
The symptoms vary depending on the extent of the injury. Extremely swelling and pain, in addition with the inability to ambulate, are major signs. In surgical-emergency cases, the broken bone can pop out of the skin or the swelling can cut off the blood circulation to the leg. Significant fractures may cause dislocation of the ankle. On the other hand, less severe breaks may have mild pain/discomfort and patients may be able to put some weight on their foot.
Causes of Ankle Fracture
Most ankle fractures occur following an acute twisting injury, where the foot is planted on the ground and the body rotates around it. Inversion injuries are common where the foot turns inward on the leg and fractures the outside ankle bone. Additional causes are slips, falls (especially when landing on one’s foot) and poor bone state.
Ankle Fracture Treatment
The type of ankle fracture surgery depends on the involved bone(s), fracture orientation, displacement, separation of the bones, the mechanism of injury and the fracture’s/ankle’s stability.
The basis for ankle fracture surgery is to manually place the broken bone(s) in proper alignment. After, while bone healing takes place, we stabilize the fractured bones, often with screws and plates.
The location and orientation of the fracture generally determines the method and type of fixation used to fixate the bone.
Stable ankle fractures can be treated without surgery, by limiting activity until the bone has healed. Foot immobilization could be achieved by using either a boot or casts with (or without) crutches, depending on the severity of the fracture.
Most unstable ankle fractures benefit from surgery to stabilize the fractures and ensure that the joint heals in an anatomic position.
Finally, with or without surgery, broken bones take 6-8 weeks to mend.
