Ankle dislocation

Introduction to ankle dislocation Because the talus is in the acupoint, surrounded by strong ligaments, it is firm and stable, so the dislocation of the ankle is extremely rare, and there are many fractures. This section discusses the dislocation, which is combined with the minor fracture. Injury, referred to as dislocation of ankle joint (dislocation ofanklejoint), the most common dislocation after this injury, the second dislocation, followed by the most dislocation. basic knowledge The proportion of illness: 0.002%-0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: fracture

Ankle dislocation

Direct damage (50%):

When the ankle joint is flexed, the calf suddenly receives a strong forward impact force, which can cause dislocation of the ankle joint. When the ankle joint stretches back, it falls from a height, and the heel strikes the ground, which can cause dislocation of the ankle joint. Compressive injury can cause dislocation of the ankle joint when the lower ankle joint is separated.

Ankle dislocation prevention

1. Strengthen health publicity and education, use television, radio and other forms to carry out popular science education and publicity on the causes and prevention methods of such injuries, such as avoiding wearing high-heeled pointed shoes on rough roads, it is prevention Important measures for ankle injury.

2. Strictly abide by labor discipline and standard operation, check protective equipment, maintain protective posture according to routine, maintain correct posture, avoid bad posture, and prevent acute sprain and chronic strain.

3. Appropriate physical labor or physical exercise can prevent the occurrence of ankle injury to a certain extent and reduce the damage to a minimum, so that the weak, loose ankle ligament and soft tissue are enhanced, and the flexibility of the ankle joint activity is increased. The stiffness of the bone.

4. Early diagnosis after injury, correct choice of treatment measures, can not rush to premature activities, to take a full rest, brake, so that the damaged tissue is well restored.

Ankle dislocation complications Complications

This disease is most often associated with fractures, nerve damage and so on. For example, if there are dislocations in the shoulder joint, about 30-40% of the patients have large nodules fractures, or a surgical neck fracture of the humerus, or a compression fracture of the humeral head. Sometimes the joint capsule or the scapula is avulsed from the front attachment, and the healing is not good. Cause habitual dislocation. The biceps femoris tendon can slip backwards, causing joint reduction.

Ankle dislocation symptoms Common symptoms Inner axillary area pain swelling Ankle pain Simple fracture Joint pain Single leg and half aching

Pain, swelling, deformity and tenderness appear in the ankle after injury. The posterior tibia of the posterior dislocation is prominent under the skin and can be touched. The distance from the anterior border of the tibia to the heel increases, and the forefoot becomes shorter. The anterior dislocation is talus. Located under the anterior humerus, the ankle joint dorsiflexion is limited, and the appearance of the upward dislocation can be seen that the injured limb is locally shortened and the swelling is severe.

Ankle dislocation examination

The diagnosis of dislocation of the joint is not difficult. Generally, the diagnosis can be made according to its medical history and clinical manifestations, as well as simple physical examination. However, the clinical application of the auxiliary examination can more clearly understand the dislocation, including whether the surrounding bone is damaged. .

X-ray examination: It is important to determine the direction and extent of dislocation and the presence or absence of a combined fracture.

Diagnosis and diagnosis of ankle dislocation

Traumatic history, local symptoms, pain, swelling, deformity and tenderness in the clinical manifestations. The posterior tibia of the posterior dislocation is prominent under the skin and can be touched. The distance from the front of the humerus to the heel increases, and the forefoot becomes shorter. The talus is located under the anterior humerus, and the dorsiflexion is limited. The upper extremity has a shortened appearance. The conventional X-ray film can confirm the diagnosis, and the CT scan can find the micro fracture.
