Ankle Dislocation: Diagnosis and Treatment

Pure ankle dislocation is a very rare injury. More commonly fracture and dislocation both are present.

Before reading further it would first be good to know the relevant ankle anatomy. (skip this it you have already read the page)

Pure dislocation of the ankle joint is caused by a force directed posteriorly over the ankle joint with the foot flexed downwards. It is caused by high energy injuries such as road traffic accidents.

In majority of cases the skin and other tissues covering the bones of the ankle break down, resulting in a contaminated wound.

Symptoms are similar to ankle fracture.

Diagnosis is by clinical history and examination. X rays show the position of dislocated bones and rule out the presence of fractures.

As this is a emergency hence treatment includes urgent reduction (realignment) of the dislocated bones. This is followed by immobilization in a plaster cast for 6 to 8 weeks.

Complications include

  • infection
  • osteochondral fractures due to cartilage injury
  • late arthritis
  • calcification of ligaments

My compliments to you and your website. It provides the necessary knowledge and guide to bridge the gap caused by the bits of (mis)information given on most sites. Your website provides a short course on the subject. It not only guides the user, it also provides fundamental knowledge for researching the topic. Giving the user a remarkable and unmatched understanding of their topic. An ounce of knowledge makes for a better patient. I've been longing for a website such as yours. A website that is filled with information a layman can use. Its Not too complicated that it discourages the user.

Thank You for bridging the gap for me and for everyone else.
