1) Inversion ankle sprains
Inversion ankle sprains are the most common type of soft-tissue injury. These types of sprains also go by name of the lateral ankle because the lateral ligaments of the foot joining the bone are involved in the injury. The function of the lateral ligaments is to prevent excessive inversion of the ankle. These lateral ligaments aren’t much strong as the ones on the other side of the ankle, due to which inversion sprains are more likely to happen than eversion sprains.
2) Eversion ankle sprains
These sprains also go by the name Medial sprains because of the medial and Deltoid complex ligaments involved in the injury, which is a group of four separate ligaments. These ligaments make up a triangular shape, which is the Greek letter Delta, hence the name. These four ligaments are the anterior tibiotalar, tibiocalcaneal, posterior tibiotalar, and tibionavicular. The names correspond to the bone they connect.
If somehow, the deltoid ligaments experience enough pressure to be the reason for the injury, there are chances of structural injuries along with deltoid ligament sprains, such as fracture or dislocation. Hence, always get an evaluated opinion from a licensed professional to rule out the possibility.
3) High Ankle Sprain
This type of sprain happens when ligament between the bones tibia and fibula gets damaged. The joint is called the ankle syndesmosis, hence the high ankle sprain is also known as Syndemosis sprain. The tight webbing of ligaments is bound together by the interosseous membrane. The severity of the sprain could be a first-degree high ankle sprain when the few ligament fibers of the interosseous membrane are damaged.
Second-degree sprain when more damage is done to tibia-fibula joint and extreme damage to the interosseous membrane. A Third-degree high ankle sprain is when a joint is possibly dislocated and the interosseous ligament is completely torn apart.
High ankle sprains are caused mainly due to twisting injuries occurring from playing sports that have a lot of cutting and contact involved. For example, football, basketball, roller derby, etc. The twisting is caused by extreme ankle dorsiflexion and an external rotation of the shin bone.
