An ankle sprain is the most common injury to the ankle and the long term consequences of an ankle sprain is a common cause of chronic ankle pain. The most common type is the inversion ankle sprain, in which the ankle rolls over on the outside.
An ankle sprain is the stretching and tearing of ligaments - in the sprained ankle the most common damage is done to the talo-fibula ligament (if the ankle sprain is worse, the calcaneo-fibula ligament can also be damaged) - sometimes the tendons also get damaged.
Sprained ankle causes:
Anything that makes the ankle 'tip over' increases the chance of an ankle sprain - this can occur in sport (eg jumping and landing on someone's else's foot), walking on uneven surface, twisting motions etc.
A number of factors predispose to ankle sprains:
* poor rehabilitation of a previous sprained ankle
* poor proprioception (proprioception is the ability to sense where a joint is .... if you don't know where your ankle is, the muscles will not be able to prevent the ankle sprain)
* some feet are very easy to 'tip over' - this is common in those who frequently 'roll the ankle', without actually doing any damage and spraining the ankle
* weak muscles (they are just not strong enough to prevent the sprain occurring)
Ankle sprain types:
The sprained ankle is often classified as to how severe it is:
First degree ankle sprain:
* Some stretching or mild tearing of the ligament.
* Little or no functional loss - the joint can still function and bear some weight (...but hurts!!!).
* Mild pain
* Some swelling
* Some joint stiffness.
Second degree ankle sprain:
* Some more severe tearing of the ligaments
* Moderate instability of the joint
* Moderate to severe pain - weightbearing is very painful
* Swelling and stiffness
Third degree ankle sprain:
* Total rupture of a ligament - there is a loss of motion
* Gross instability of the joint - joint function is lost
* Severe pain initially followed by no pain
* Severe swelling
What to do when it you get an ankle sprain or sprained ankle?
The sooner treatment starts for a sprained ankle, the greater chance to prevent chronic pain and long term instability.
For all grades of ankle sprain follow the R.I.C.E. principles as soon as possible:
* Rest your ankle - do not walk on it.
* Ice - this helps to keep the swelling down. Use ice on the injury several times a day for 15-20 minutes (more than 20 minutes is not advised)
* Compressive bandages are needed to immobilize the ankle sprain and to support the injury.
* Elevate the ankle above your heart level for as much as you can for 48 hours.
If the sprain is a 2nd or 3rd degree ankle sprain, seek professional advice immediately.
Sprained ankle treatment
If the ankle sprain is a 2nd degree sprain, then in addition to the R.I.C.E. principle, a more effective means of immoblising the ankle (splints) may be needed. Anti-inflammatory medication may also be used to help.
If the ankle sprain is a 3rd degree sprain, cast immoblisation is needed for at least 2-3 weeks. Surgery to repair the ruptured ligament is ont often needed.
Physical therapy modalities (such as ultrasound) and manual therapy modalities (such as friction massage) are often used when the acute phase is over.
As soon as treatment is instigated, consideration must be given to adequate rehabilitation:
* exercises to increase proprioception
* ankle braces and strapping to facilitate activity
* muscle strengthening and flexibility exercises
* gradual return to any sporting activities
* maintain fitness by doing alternative activities
