ANKLE

Most people refer to their ankles as 'left' or 'right'. Others 'good' and 'bad'. Which camp do you fit in?

The ankle is made up of three joints:

  • Talocrural

  • Inferior tibiofibular; and

  • Subtalar

The talocrural joint is the main part of the ankle. It occurs where the tibia meets the talus and acts like a hinge (up and down movement).

The inferior tibiofibular joint doesn't move much and is held together by a very strong ligament called the interosseous ligament. The inferior tibiofibular joint is also referred to as the syndesmosis and provides stability to the joint.

 The subtalar joint is between the talus and calcaneus and allows for inversion and eversion of the ankle (sideways movement). 

Our ankles are made in such a way that they can be flexible and conform to uneven grounds, as well as rigid during impactful activities like running and jumping. Ankles are amazing!

Medial and lateral ligaments on either side of the ankle prevent excessive inversion and eversion. The medial ankle ligament is called the deltoid ligament and is comprised of tibionavicular, tibiocalcaneal and tibiotalar fibres.

There are three lateral ankle ligaments; the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL) and posterior talofibular ligament (PTFL).

 

The lateral ligaments are more commonly injured than the medial ligaments, however lateral ligament injuries generally take less time to heal than medial ligament injuries.

Other injuries to the ankle can include fractures, tendonitis, synovitis and arthritis.
