Ankle Fractures

sprained-ankle-006When an ankle injury occurs, one of the main concerns of the doctor is whether there is a broken bone. It is quite difficult to diagnose a fracture (broken bone) over a sprain, a dislocation, or tendon injury without taking x-rays of the ankle.

To understand ankle injuries, we need to understand the physiology of the angle. The ankle joint is made up of three bones coming together:

  • Tibia. The tibia constitutes the main bone of the lower leg which makes up the medial, or inside, of the ankle bone.
  • Fibula.  The fibula is a smaller bone that parallels the tibia in the lower leg which makes up the lateral, or outside, of the anklebone.
  • Talus. The far ends of both the tibia and fibula are known as the malleoli. The tibia and fibula for an arch that sits on top of the talus, which is one of the bones in the foot.

The tibia, fibula, and talus are the bony elements of the angle joint. The joint capsule is the fibrous membrane that is lined with synovium which constitutes the joint architecture. The joint capsule contains synovial fluid produced by the synovium allowing smooth movement of the joint surfaces. The ankle joint is stabilized by three groups of ligaments, which are fibers that hold the bones together.

Next week, we will go into detail of the causes of ankle fractures!
