What happens during an eversion ankle sprain?
Eversion ankle sprains — occurs when the ankle rolls outward and tears the deltoid ligaments. Inversion ankle sprains — occurs when you twist your foot upward and the ankle rolls inward.
What muscles are involved in an ankle sprain?
The fibularis longus and fibularis brevis are two muscles that help to evert the foot and protect against inversion ankle sprains. Because of this, when the ankle is sprained often the fibularis muscles are strained.
What muscle does ankle eversion?
peroneus longus
The peroneus longus and Peroneus Brevis muscles, found in the lateral compartment of the leg, function to facilitate eversion of the ankle joint.
What injury is often associated with an eversion ankle sprain?
For this reason, an eversion sprain is often associated with a fracture of the fibula bone. Specifically at the lateral malleolus (bony part on the outside of the ankle). This is known as a Pott’s fracture.
What is the difference between an inversion and an eversion ankle sprain?
An eversion injury or an inversion injury causes an ankle sprain. An inversion injury occurs when the ankle twists inwards; this is more common than an eversion injury, which occurs when the ankle twists outwards away from the body.
What is the physiological response of the body to an ankle sprain?
Swelling. Bruising. Tenderness to touch. Instability of the ankle—this may occur when there has been complete tearing of the ligament or a complete dislocation of the ankle joint.
What muscles are involved in foot eversion?
Eversion of the Foot (tilting of the sole of the foot away from the midline): Performed by the fibularis brevis and fibularis longus. Inversion of the Foot (tilting of the sole of the foot inwards towards the midline): Performed by the tibialis posterior and tibialis anterior.
What muscle inverts and Dorsiflexes the foot?
The anterior compartment receives innervation from the deep fibular nerve, supplied by the anterior tibial artery, and is important in the dorsiflexion of the ankle and extension of the toes. The extensor hallucis longus specifically extends the hallux, dorsiflexes the foot at the ankle, and inverts the foot.
Why are inversion sprains more common than eversion?
Inversion injuries are far more common than eversion injuries due to the relative instability of the lateral joint and weakness of the lateral ligaments compared to the medial ligament. Eversion injuries are seen occasionally.
What muscles are involved in eversion of the foot?
Is there such a thing as an eversion ankle sprain?
Eversion Ankle Sprain | Medial Ankle Sprain. An eversion ankle sprain is a tear of the ligaments on the inside of the ankle. It is not as common as an inversion ankle sprain and is often accompanied by a fracture of the fibula bone.
Where is the eversion ligament in the ankle?
An eversion ankle sprain is an injury to the deltoid ligament, located on the medial side (inside) of the ankle. Eversion sprains are fairly rare, accounting for about 5% of all ankle sprains.
Why is an eversion sprain more common than a fibula fracture?
Another reason is that the medial ligaments on the inside of the ankle are much stronger than the lateral ligaments on the outside. For this reason, an eversion sprain is often associated with a fracture of the fibula bone. Specifically at the lateral malleolus (bony part on the outside of the ankle). This is known as a Pott’s fracture.
What kind of sprain is on the inside of the ankle?
An eversion sprain is a tear of the deltoid ligaments, on the inside of the ankle. It is often called a medial ankle sprain or a deltoid ligament sprain.
