A sprained ankle (twisted ankle, rolled ankle, turned ankle, etc.) is an injury where sprain occurs on one or more ligaments of the ankle. It is the most commonly occurring injury in sports, mainly in ball sports such as basketball , volleyball , football , pickleball , and tennis .
Sinus tarsi syndrome can have a variety of causes. The most common is an inversion (rolling out) ankle sprain, which makes up 70-80% of cases, followed by pronation of the foot, which is responsible for about 20-30% of cases. [3] More rarely, excessive physical activity and other forms of foot trauma/chronic ankle injury are thought to be the ...
The Danis–Weber classification (often known just as the Weber classification) is a method of describing ankle fractures. It has three categories: [1] Type A. Fracture of the fibula distal to the syndesmosis (the connection between the distal ends of the tibia and fibula). Typical features: below level of the ankle joint; tibiofibular ...
This damages the ligaments on the inside of the ankle and fractures the fibula at the point of contact (usually just above the tibiofibular syndesmosis). A better way to visualize this is the two hands of a clock, with one hand facing 12 and the other facing 6. The vertical line they form represents the fibula of the person's right leg.
[10] [11] If a Maisonneuve fracture is left untreated, instability of the tibiotalar joint and deltoid ligament can cause a valgus deformity of the ankle. This leaves the ankle joint in a state of chronic pronation, characterised by a protrusion of the medial malleolus into the subcutaneous tissue. [11]
A sprain is a soft tissue injury of the ligaments within a joint, often caused by a sudden movement abruptly forcing the joint to exceed its functional range of motion.. Ligaments are tough, inelastic fibers made of collagen that connect two or more bones to form a joint and are important for joint stability and proprioception, which is the body's sense of limb position and movem
A trimalleolar fracture is a fracture of the ankle that involves the lateral malleolus, the medial malleolus, and the distal posterior aspect of the tibia, which can be termed the posterior malleolus.
A specialized AP stress view of the ankle is performed when there is concern for an unstable ankle injury. There are two types of stress views: gravity and mechanical. [11] In the gravity stress view, the patient lies in the lateral decubitus position with the ankle dangling over the edge of the table to mimic the mechanical stress view.
