Lateral ankle ligament reconstruction is a surgery to tighten and firm up one or more ankle ligaments on the outside of your ankle. endobj Injury to the lateral ligamentous structures usually occur after suffering an inversion type injury to the ankle. Ankle sprain is one of the most common sports injuries [1,2,3].The injury mechanism, a combination of inversion and adduction in foot plantar flexion, can cause damage to the lateral ankle ligaments [].Lateral ankle ligaments comprise anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) []. [2], This article incorporates text in the public domain from page 351 of the 20th edition of Gray's Anatomy (1918). application/pdf Isolated rupture of the CFL happens in approximately 1%, and injury to the posterior talofibular ligament (PTFL) is extremely rare. endobj A study by Broström [5] reported that ATFL rupture accounted for approximately 66% of all ankle ligament injuries, while those combined with CFL injuries comprised approximately 20%. CFL lies between the calcaneus and the peroneal tendons and forms a hammock and fibrous pulley for the tendons. The calcaneofibular ligament is a narrow, rounded cord, running from the tip of the lateral malleolus of the fibula downward and slightly backward to a tubercle on the lateral surface of the calcaneus.

In the event of a combined ATFL and CFL rupture, the medial ligament acts as the centre of rotation during movement, allowing the talus to rotate internally – having lost its lateral restraints. A severe ankle sprain typically causes severe signs, which may be similar to those seen with an ankle fracture. <> They range from mild to severe, depending upon how much damage there is to the ligaments. Injuries typically occur during plantar flexion and inversion; the ATFL is most commonly torn. The sensitivity of detection of partial tear was 83% and the specificity was 93%. [2] It may be injured individually, or in combination with other ligaments such as the anterior talofibular ligament and the posterior talofibular ligament. uuid:a92f2c2a-a992-11b2-0a00-b0061d62ff7f AppendPDF Pro 5.5 Linux Kernel 2.6 64bit Oct 2 2014 Library 10.1.0 <> It’s also known as the Brostrom procedure.

More than 50% of the ligament remains. The calcaneofibular ligament is a thick, oval, cord-like ligament and extends from the distal tip of the fibula to the lateral wall of the calcaneus. Grade III has tenderness over the ATFL, CFL and PTFL (posterior talofibular ligament), significant diffuse ecchymosis and edema seem to be uniformly present, weight-bearing impossible without pain, ligamentous damage is a complete tear, and there is definite instability. one of three ligaments that make up to Lateral Collateral Ligament of the ankle. The medial (deltoid) ligaments is much stronger than the lateral ligament and is therefore injured much less frequently. endobj Usually at that point the injury stops but in some severe cases the ligament in the back of the ankle called the posterior talofibular ligament (PTFL) tears. Individuals with generalized hypermobility of the joints or a previous history of ankle ligament injury are at greater risk of ankle injuries. Clinically, the most commonly sprained ankle ligament is the ATFL, followed by the CFL. Your ankle is a hinge joint that allows motion up and down, and from side to side. %PDF-1.4 %���� The sensitivity of detection of sprains was 100% and the specificity was 90%. There are multiple factors that may predispose someone to an injury to the lateral ankle ligament complex but 85 percent of the time, the injury is from a plantarflexed and inverted foot.
