Early Ankle Sprain Treatment can help to speed recovery and minimize the symptoms. Here are a few simple treatment steps to follow for sprained ankle. For better understanding of Ankle Sprain Treatment, lets first understand-
What is Ankle Sprain?
An Ankle sprain is actually an injury to the ligaments of the ankle joint, which are elastic, band-like structures that hold the bones of the ankle joint together and prevent excess turning and twisting of the joint. In normal movement, the ligaments can stretch slightly and then retract back to their normal shape and size. A sprain results when the ligaments of the ankle have been stretched beyond their limits. In severe sprains, the ligaments may be partially or completely torn.
The ankle joint is fairly unstable and largely depends on the ligaments for its stability. The ankle sprain is of two types-
1-Pronation or eversion type.
2-Supination and inversion type.
The most common type is the inversion ankle sprain (85%), in which the ankle rolls over on the outside. 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.
Mechanism of Ankle sprain
The ligament is injured when the plantar flexed foot is suddenly forced into inversion, which may cause rupture, sprain of lateral ligament.
The injury is common in sports activity. It is quite common when a person slips off or walk on uneven surfaces. The foot is forced into inversion and plantar flexion which results in external rotation of tibia. The site of injury is generally the centre and distal attachments of anterior and middle band of the ligament.
When sudden inversion force occurs with the ankle in mid position of dorsi and plantar flexion, the injury involves the calcaneo-fibular ligament(CFL). Whereas when the excessive inversion-adduction movement is associated with forced plantar flexion, the injury commonly involves anterior talo-fibular ligament(ATFL). This can be identified by the site of pain and tenderness. Pain and tenderness over talus indicates injury to talo-fibular ligament while the same over calcaneus indicates the involvement of calcaneo-fibular ligament. This identification is necessary for prompt treatment.
Sprained ankle is often classified as
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- Return to activity/functional phase in 1-2 weeks with proper ankle sprain treatment.
Second degree ankle sprain:- Some more severe tearing of the ligaments-Moderate instability of the joint- Moderate to severe pain - weight-bearing is very painful- Swelling and stiffness- Return to activity/functional phase in 2-3 weeks with proper treatment.
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- Usually extensive bruising- Return to activity/functional phase in 3-6 weeks with proper ankle sprain treatment.
Risk factors predisposing 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)
-Use of high heels.
Sprained Ankle Symptoms
History- The patient describes 'going over' at the ankle.
Pain- There is sharp pain just below and anterior to the lateral malleolus. Passive stretching and weight bearing increase the pain. Pain because the nerves are more sensitive: The joint hurts and may throb.
Swelling- When an ankle is injured with a sprain, tissue injury and the resulting inflammation occur. Blood vessels become "leaky" and allow fluid to ooze into the soft tissue surrounding the joint. White blood cells responsible for inflammation migrate to the area, and blood flow increases as well. This is present from the lateral border of tendo-achilles, over the lateral malleolus along the dorsum of the foot. In severe injuries, swelling may spread to the dorsum of the toe and up to the leg.
Bruising- This appears under the lateral malleolus and over the dorsum of the foot.
Loss of function- All weight bearing is painful, so the patient cannot run and has a gait with a very short stance phase on the affected foot.
Physical examination of Ankle
Physical examination reveals mild swelling in grade 1 sprains and moderate to severe swelling in a diffuse pattern in grade 2 and 3 sprains. Tenderness is usually elicited at the anterior edge of the fibula with ATFL injuries and at the tip of the fibula with CFL injuries. The region of the syndesmosis and the base of the fifth metatarsal should also be palpated to rule out injuries to these structures.Once proper physical examination and diagnosis is done Ankle sprain Treatment can be started.
The Anterior drawer test and the Talar tilt test are commonly used to identify signs of joint instability. The Anterior drawer test is performed by stabilizing the distal tibia anteriorly with one hand and pulling the slightly plantar flexed foot forward with the other hand from behind the heel. A positive finding of more than 5 mm of anterior translation indicates a tear of the ATFL. The Talar tilt test is performed by stabilizing the distal tibia with one hand and inverting the talus and calcaneus as a unit with the other hand. A positive finding of more than 5 mm with a soft endpoint indicates a combined injury to the ATFL and CFL. It is important to always compare the affected ankle with the contra lateral side because some patients are naturally very flexible (generalized ligament laxity), and this could result in false positive test.
Differentiating between a sprained ankle and an ankle fracture can be difficult, and sometimes an x-ray is needed.
Examination of the Ankle after an inversion injury
A good thorough examination of ankle joint is necessary for Ankle Sprain Treatment, which include-
-Palpation of the lateral collaterals (ATFL and CFL)
-Medial palpation of the deltoid ligament
-Palpation of the proximal fibula close to the knee to rule out a Maisonneuve fracture (tearing of the interosseous membrane and proximal fibula fracture).
-Squeeze test to rule out ankle syndesmosis tearing with resultant ankle mortise instability.
-Palpation of proximal (base) fifth metatarsal to rule out avulsion fracture from peroneus brevis pull.
-Anterior drawer and inversion (talar tilt) stress testing.
-External rotation (Cotton) test to test for syndesmosis injury.
-Motor testing of posterior tibial (inversion) and peroneal (eversion) tendons.
Ankle Sprain Treatment
Acute Stage- Ankle Sprain Treatment
-Grade 1 sprain: 1-3 days
-Grade 2 sprain: 2-4 days
-Grade 3 sprain: 3-7 days
Goals-Acute Stage-Ankle Sprain Treatment
Decrease pain and swelling, protect from re injury and maintain appropriate weight bearing status.
Concentric/Eccentric and isotonics (theraband and weight cuff exercises) for inversion, eversion, plantar flexion, dorsi flexion, peroneal strengthening.
-Proprioceptive training ( Progress from non-weight bearing to controlled weight bearing to full weight bearing). Standing BAPS board. Standing wobble board. Single leg balance activities (Stable to unstable surfaces, without to with distractions). Proprioceptive training has a major role in Ankle Sprain Treatment.
2) Continue modalities as needed, specifically after exercise to prevent re occurrence of pain and swelling.
3) Taping, Bracing and orthotics used as needed. To avoid re injury.
