Ankle Dislocation

Ankle Dislocation

Ankle dislocation

is a traumatic injury that results in the dislocation (moving out of the original place) of an ankle joint’s bones (tibia, fibula and talus). The dislocation of a bone is a severe injure that causes excruciating pain which can take months before it can actually heal. The problem with dislocations is that there would also be a bone fracture accompanying the dislocation.

 

Pure dislocations (no fracture involved) are a very rare form of injury

 

.

Types of Ankle Dislocation:

They can be classified into four types –


  • Congenital or developmental dislocation.

    Occur during the embryo stage itself.


  • Traumatic dislocation

    . Result of an injury to the ankle. Are acute recurrent.


  • Pathological dislocation.

    Resultant of a disease.


  • Paralytic.

    As the name suggests, this is the resultant of an attack of paralysis.

Signs:

The signs and symptoms presented by a dislocated ankle joint are similar to that of a fractured ankle. These will be bruising, swelling, severe pain, deformity, tenderness to touch and inability to bear weight. But, proper X-rays are required to confirm the dislocation.

Complications:

The following are the complications that can arise from this injury-

  • bone infections
  • possible development of arthritis
  • ligaments’ calcification
  • weakened cartilage

Treatment:

Immediate attention is necessary to handle a dislocation of the ankle, else it could lead to a permanent disability as the blood vessels that get stuck in the dislocation could be deprived of blood supply.

  • As the symptoms are immediate, applying ice packs while making sure that the ankle is stable will alleviate the swelling and fluid build-up.
  • The first thing that a doctor would do would be to relocate the displaced bone to its proper location and then cast the leg in order to keep it in place, thus giving it a chance to heal.
  • As part of the surgery of

    ankle dislocation

    , screws and pins would have to be used to hold the ankle in place. These would be removed after 12 weeks, but if the injury is a severe one, these could become permanent. The recovery period after a surgery is almost one year.
