Daily load on the ankle is huge, because it is capable of carrying the full weight of the human body. For this reason, the ankle called the most vulnerable joint. Even the most minor injury or damage to a component of the ankle lead to the fact that a person loses the ability to move normally, as these situations involve severe pain. The bones of the ankle joint is very fragile.

The Important point is the attentive attitude to any manifestations of pain in the legs or changes in the feet. In this situation should immediately contact the doctor. Better pathology to identify in a timely manner and to begin therapy. Only in this case, considerably reduces the risk of complications.

The article will examine the anatomy of the ankle ligaments.ligaments of the ankle joint anatomy

The structure of the ankle

Anatomy of the ankle is quite complex in its region are connected to muscles, bones and ligaments. Thanks to the ankle of the person can keep balance and move in the usual way. Muscular frame allows bones to withstand considerable loads, and also protects the musculoskeletal system from injury. Located around the blood vessels provide nutrition to all ligament of the ankle joint.

Anatomy is not simple, so it often causes damage that is caused by heavy loads. To avoid injury, complications and inflammatory processes, it is necessary to understand the structure of the ankle.

Bone frame

Ankle joint is located at the junction of the small and large tibia and the talus bones. Immediately there is talofibular ligament. All these bones form a cavity, in which there was joint. They also take the brunt of the burden during the movement, as it is the area of the ankle accounts for all the mass of the human body.

A Cavity formed by the talus and the tibial bones, is divided into three parts: the outer ankle, distal and inner surface of the tibia. To the outer ankle is attached fascia and tendon, including hyaline cartilage. Muscles, joints, and tendons connect the bones of the ankle and foot. This gives the foot flexibility and provides when walking good cushioning. The structure of the ankle joint unique.

Anatomy of the calcaneus

Heel bone can safely be considered the most massive of all those located in the region of the foot. Anatomy the calcaneus is unique, its main function is a kind of jumping movement. It is massive and has high endurance, but under the influence of many factors can be easily damaged. What is the pathology in its region can be formed?

The Heel bone connects with other bones. Located directly under the talus bone, which connects the heel short heel bone. Behind her powerful the hill, from which depart on the sole lateral and medial processes. The second is connected with the tendon of the flexor of the toes. Then I can see the connection of the lateral process long plantar ligament. The upper surface of the calcaneus protects the back of the talus articular surface, associated with the posterior calcaneal articular surface of the subtalar joint.

Muscle

The Ankle can move with up to eight muscle bundles that give the ability to bend the leg and rotating movement in a circle. This allows a person to move around in normal mode and keep the balance. The legs are not folded, as the security is provided by the muscles.

If muscles bad contract and is a violation of their flexibility, the person loses the ability to move over uneven surfaces, the legs can easily podvorachivaetsya, thus increasing the risk of injury to the ankle joint.

The Ankle muscles can be divided into several major groups:

  • Flexing. These include plantar, triceps, posterior tibial muscle and the flexor muscles of the fingers.
  • Extending. It is the extensors of the fingers and anterior tibial muscle.
  • Predatory. They are responsible for rotational movements and include short and long peroneal muscles.
  • Foot support. This group includes the extensor of the thumb and the anterior peroneal muscle.

Bundles

Anatomy of a ankle ligaments is presented below.

They are responsible for the normal functioning and movement in the joint, also they hold the marrow elements. Most powerful is the deltoid ligament. It connects the talus, calcaneus and navicular bones (of the foot) with inner ankle.

A Powerful education and ligaments of the tibiofibular syndesmosis.

The Joint capsule of the ankle joint is strengthened, three groups of strong ligaments. Collateral (side) divided into the inner (medial) ligament of the ankle joint and outer (lateral).

Hold together the tibia and fibula provides the interosseous ligament, it is kind of a continuation of the interosseous membrane. It goes into the rear bottom, which prevents excessive rotation of the joint inward. Rotate in the outer direction do not allow front lower tibiofibular ligament. Its location, between the calcaneal-fibular ligament, located on the surfacethe tibia and the external malleolus. Excessive rotation of the foot outwards prevents the transverse ligament, which is located under the tibiofibular.

Achilles Tendon

It is the strongest and biggest in the body. This is because the Achilles tendon allows a person to go to, which means taking on a greater burden. The average strength of the tendon is determined by about 350 kg while trying to break. He has a big enough vulnerability in view of the fact that it is not flexible. Functions that performs the Achilles tendon are:

  • The Implementation of walking right.
  • Damping of movement.
  • Normal traffic stop.
  • The Ability to run and jump.

Deformation and injury of the Achilles tendon typically occur in case if a person continually wears uncomfortable shoes. It is also possible the development of pathologies such as deformity of the foot or flat feet. The reason for rupture of the tendon can become severe hypothermia, mechanical injury or wearing of high heels.

Nerves and blood vessels

The Circulatory system plays a significant role in the ankle joint. It provides the necessary tissue nutrition. Ankle are supplied with blood through three large arteries, however, damage to the joint can lead to deformation of the vessels, which will trigger insufficient flow to the feet.

Also, the ankle contains nerves, providing the sensitivity and the normal functioning of the feet and muscles. If nerve endings are damaged, may develop muscle weakness, loss of sensation and numbness of the feet.

Causes of ankle pain

When there is pain in the ankle, the person becomes hard to move. Occurs ankle swelling and bruising of the skin. It becomes impossible to fully step on the foot, as the pain intensified. Ankle, thus losing the ability to hold the weight of a person.

The Pain in the damaged ankle joint may radiate to the region of the Shin or knee. Athletes are at increased risk of development of pathology of the ankle since during training the stress and load on the joint exceeds the permissible limits. The lateral ligament of the ankle joint gets damaged very often.deltoid ligament

The Pain in this area indicates a serious disorder that requires medical treatment. Pain syndrome seen after injury, sprains, dislocations or fractures. It can also indicate signs of damage of the synovial cavity or cartilage.

How to heal a sprained ankle? This is a common question.

To make an accurate diagnosis and determine the cause of the damage can only specialist. As a rule, inspection is performed and assigned to additional tests like ultrasound or x-ray. If necessary, may also be assigned routine analysis of blood and synovial fluid fence to histology.

Most Often ankle pain are the result of the development of the following diseases:

1. Arthritis.

2. Osteoarthritis.

3. Gout.

All of the above-named diseases are manifested by impaired motor activity and inflammation of the joint. The character of the pain is increasing and passing through some time. Gout causes a strong swelling and intense pain.

The cause of the pain in the ankle joint may also be a cyst or other tumor is benign or malignant nature. In this case, the pathology is palpated, and the tumor starts to hurt when you press and feel when driving. If the pain is accompanied by swelling, should immediately go to the doctor.

If you run the disease may develop complications, such as complete loss of ability to move the joint, as it accumulates in bone. This inflammatory process can move on to the neighboring joints and tissues, which will cause even more complications. How to heal a sprained ankle? It takes on average from a few days up to a month to heal, but the process can take up to six months, depending on severity.calcaneus anatomy

Therapy

Therapy for pain in ankle depends on the nature and severity of the disease. In the case of an inflammatory process or injury to the joint provides for unloading of the affected limb. This will speed up the recovery process and prevent further destruction of the joint tissues. In order to relieve inflammation and pain usually are prescribed nonsteroidal anti-inflammatory drugs, in some cases, this can be a corticosteroid.

In the rehabilitation period the patient shows physiotherapy, physiotherapy, mud therapy and other methods. Also prescribed painkillers in the form of ointments and gels. Sometimes the cause of the disease is an autoimmune disease, and the accumulation of salts in the joint. In this case you will need long-term special treatment in a specific pattern. Therapy is not simptomatika,and with the aim of eliminating the causes of pathology.

Removal of cysts and tumors, surgical intervention. In the course of the meeting removes the tumor and regenerate damaged tissue. This measure is used in advanced cases where conservative therapy does not have the desired effect.

Treatment stretching

The Most common pathology of the ankle-a sprain of the deltoid ligament. The specialists recommend the following steps to restore damaged tissues.

1. Stress reduction and physical activity joint. This is done to prevent further damage of the joint.

2. Local cooling of the joint. Ice can reduce the swelling and to create a sense of numbness that relieve pain. Apply it to the damaged joint makes sense for the first 48 hours after injury. Cooling procedure should not exceed 20 minutes, otherwise it may be frostbite. Between the two procedures, you should take a break of 1.5-2 hours. Ice can be wrapped in a towel.lateral ligament of the ankle joint

3. Bandaging elastic fabric. For this purpose, special stretch bandages. Roll up the joint should not perezalivat. If there is numbness, then a bandage was applied incorrectly. Such a measure allows to remove the swelling and to ensure the restriction of movement. Bandaged leg required a day while walking at night to leave the bandage on don't need.

4. The foot should be higher in the raised position relative to the body. Lying on the couch, this can be achieved by putting the injured limb pillow. In the sitting position the leg can be put on the chair.

5. The damaged joint is strictly forbidden to overheating, especially in the first week. Rubbing alcohol and massage can worsen the condition. Therefore, you should avoid hot baths and saunas.

6. If during the day after injury, the function of the ankle joint are not restored, and the condition of the joint deteriorates, you should seek medical attention. It is important to remove almost all the load with sore feet while walking. For this you can rely on the whole foot, not the heel.

Prevention

The Main measure that helps prevent damage to the deltoid and talofibular ligaments, is considered respect to the ankle. Most often disease develop those who lead an inactive lifestyle, or, conversely, excessively load the joints. Compliance with certain of the recommendations will allow to avoid problems with the ankle.

1. Balanced diet and bring the weight to normal values. Excessive body weight increases the already significant load on the ankle.

2. To avoid this deficiency. This applies to food, which should be correct, as well as taking special vitamin complexes.

3. To prevent circulatory disorders. This requires to regularly perform special exercises.

4. Quitting bad habits like alcohol or Smoking. Such habits adversely affect the human circulatory system.

5. If the work involves an intense workload, should find time for break and rest.bones of the ankle joint

Conclusion

It is Important to undergo routine examination. This will help to identify the pathology at an early stage and to avoid serious complications. This is especially true of those in whom there is a genetic predisposition to articular diseases. Any injury is also a cause for immediate treatment to the doctor, as even slight damage may lead to unpredictable consequences.
