Although the anterior drawer test at the ankle joint is commonly used in routine clinical practice, very little is known about the sharing of load between the individual passive structures and the joint response at different flexion angles.A mathematical model of the ankle joint was devised to calculate ligament fibre recruitment and load/displacement curves at different flexion angles. Ligamen...

One hundred patients with acute ruptures of the lateral ligaments of the ankle were randomly allocated either to conservative treatment in a plaster cast or to operative repair. With the aid of stress tenography, the extent of the injury was established. There were 30 patients with isolated anterior talofibular ruptures and 20 with additional calcaneofibular ligament ruptures in each treatment ...

Ankle sprains are common: one estimate is that there is one per day per 10 000 of the population. 1 Has there been any progress in the management of this so-called minor injury? The important decisions relate to the rupture of ligaments. It is known that the anterior talofibular ligament is almost always the first or only ligament to rupture. Brostrom 2 found that combined ruptures of the anter...

Patients with subtalar joint instability are often diagnosed with ankle instability. Only after a prolonged period of time in which a patient does not improve after treatment for ankle instability is subtalar joint instability considered. To develop a clinically relevant method to diagnose subtalar joint instability, the kinematics of the simulated unstable subtalar joint were examined. A 6 deg...

In a simplified way, one can divide the subtalar joint into two parts, an anterior and a posterior part. Anteriorly, the talar head is located on the anterior and middle facets of the calcaneus, forming the acetabulum pedis with the posterior surface of the navicular bone.1 However, it is important to mention that the talar head is not only supported by the articulating surfaces of the calcaneu...

Case 1 description Buddy is an active 33-year-old man who presents to the emergency department (ED) complaining of pain in his left ankle and foot after falling while back-country skiing 3 days ago. The fall involved a moderatespeed slide down a steep chute and rotational release of the left leg from the ski binding. Buddy experienced immediate pain to the lateral malleolar region. Immediately ...
