The tibia, also called the shin bone, is the larger, weight-bearing bone of the lower leg. Of the weight transferred through the leg, about 90% is carried by the tibia. The fibula is the smaller bone on the outside of the leg. It only carries about 10% of your body weight.
Both the tibia and the fibula wrap around the talus to form the ankle joint. The bony prominences at the ankle are called the medial malleolus (the end of the tibia) and the lateral malleolus (the end of the fibula). The ends of these bones for a cup for the talus to sit within.
The Broken AnkleWhen a broken ankle occurs, the injury may be to the end of the tibia (the medial malleolus) or to the fibula (the lateral malleolus), or both. There are many different type of ankle fractures, and attempting to discuss them is the subject of textbooks, not pamphlets like this. The point is, every ankle fracture MUST be treated individually. You must see your doctor and go over the treatment plan with him or her.
There are some general treatment principles of ankle fractures that can be explained here. Common symptoms of an ankle fracture include:
- Pain to touch
- Inability to walk on the leg
- Deformity around the ankle
Once the injury has been determined, a treatment plan is made that is appropriate for the type of ankle fracture. For more information about ankle fracture treatment:
