The most common ankle sprain is an ‘inversion’ sprain on the outside of the ankle. This is usually associated with sport or falls or other high impact activity. There are particular foot types with a high arch, which will be more vulnerable to ankle instability and sprains, or if rehabilitation hasn’t been complete with a previous injury. The foot is particularly vulnerable when rolled inwards with the toes lower than the heel.
It is the tearing of ligaments that support the ankle that causes the pain, swelling and lack of mobility. It is possible for other ligaments to be torn in the injury and fractures of a metatarsal bone is not uncommon. First aid of RICE (rest, Ice, compression and elevation). Will reduce the secondary affects of swelling and soft tissue bleeding. Should lack of mobility or pain persist a professional consultation is advised to determine if other foot structures are involved. Heat, Alcohol, Running and Massage should also be avoided in the first 48 hours
Unstable feet and ankles can be associated with a number of different conditions. Hypermobility or the ability of ligaments and tendons to stretch excessively and allow the joint to go beyond its normal range of motion can cause joint or tendon discomfort. There is also a tight band that lies over the ankle tendons to hold them in place that can be irritated along with the nerve that travels through it. Occasionally the ligaments within the ankle joint can be affected by foot injury and trauma. The high arched unstable foot can be rebalanced by customised orthotics that allow for the arch height and function of the foot.
