Cross Fibula
One of the most common injuries of the lower extremities is an ankle sprain. While people often associate an ankle sprain in sports, all kinds of people his sprained ankle every day. It's an injury that could be caused by something as simple as walking on a curb, stepping on a stone, or missing a step. Because so many people suffer from ankle sprains, there is great interest in its prevention. This series of articles will focus on the best ways to prevent ankle sprains. This information is based on decades of study and research of some of the leading experts in sports medicine and treatment of musculoskeletal injuries.
Before exploring ways to prevent ankle sprains is important to discuss what an ankle sprain is and how it is produced. The knee joint is unique because it is built to support and stabilize most of the body weight while being relatively mobile. This apparent contradiction in the requirements for stability and mobility is one of the reasons, the ankle can be injured so easily.
To understand the first lesion to understand the anatomy of the joint. There are two leg bones. The larger of the two bones called the tibia. This bone extends from the knee joint to the ankle and makes up the bony knob located on the inner ankle. The other is the bone of the fibula, a long thin bone that travels with the tibia from the knee to the ankle. The fibula, however, is the outer bone of the leg and makes to the external bone protuberance of the ankle joint. If you feel that your right ankle, now you can feel these bones, the tibia and fibula in interior abroad. Each button is called the malleolus. The tibia and fibula join near the knee joint and just above the ankle joint. The ligament connecting the tibia and fibula above the ankle is called the distal tibiofibular ligament.
Anatomically, the ankle is classified as a set complex because it is done for more than two bones. The first two are the bones of the tibia and fibula. The third bone is irregularly shaped and called the talus. Astragalus fits perfectly into the space between the two malleoli (the word of a malleolus). Talus pivots in this space that allows point toes into ground or into the nose. This is the main proposal of the ankle, but also allows for a bit of turning inward and outward.
There are ligaments that hold each malleolus to the talus so that astragalus does not come loose and the joint can be stable. Inside the ankle, a number of ligaments that go from the malleolus of the tibia to the talus. These ligaments together are called the deltoid ligament. On the other side of the fibular malleolus joint is connected to the talus by three ligaments: the anterior talofibular ligament (in the front of the malleolus), the ligament calcaneofibular (at the bottom of the malleolus) and talofibular ligament later (in the back of the malleolus).
There are two ligaments that are important to know when learning about ankle sprains. These ligaments are bands that wrap around the entire joint called the flexor retinaculum and the extensor retinaculum. These ligaments are the tendons that travel from the leg to foot on the floor near the bones. They also help stabilize the ankle joint.
The last piece of the anatomy to consider is that muscles that control ankle motion. The tendons of several muscles crossing the ankle joint. Some of these muscles, like those found in peroneal the outside of the leg, mainly the function of moving the foot while others mainly move the toes.
Now that you have an understanding basic anatomy involved. The next article in this series describes the different types and degrees of ankle sprain. In addition, you will learn how these injuries occur.
