Oh, that ankle... The word "twisted" seems to be one of its favorite words. If the circumstances are too unfortunate, the situation can go as far as tearing ligaments☝🏻 Sadly, many athletes are familiar with this. But there is another less dangerous, but extremely discomforting condition - chronic instability of the ankle joint. This pathology causes ankle ligaments to be sprained more than once in a fairly short time interval. Instability of the ankle joint is mainly due to the fact that the subtalar joint appears to be excessively mobile. People with clubfoot and flat feet, which cause the lateral ligament to deviate in axial rotation during leg movements, are susceptible to injury.
