“Describing that part of the anterior talofibular ligament is an intra-articular structure could have implications in the evolution and treatment of this kind of injuries. “These findings suggest the behaviour after an injury will be similar to the other intra-articular ligaments, such as the twill, which are not able to cicatrize, and this makes the joint to remain unstable and in many cases it requires a surgical operation”, says Miquel Dalmau-Pastor.
“These results would explain why many sprains cause pain after the patient follows the treatment the doctor suggests. “Since the intra-articular ligament does not cicatrize, the instability of the joint produces pain so these patients are likely to suffer from another sprain and develop other injuries in the ankle”, highlights Francesc Malagelada.
“Apart from the anatomic observation in the dissections carried out at the University of Barcelona, the researchers studied the behaviour of ligaments. “The superior fascicle in the anterior talofibular ligament, apart from being intra-articular, is not an isometric structure –that is, it relaxes when the foot is on a dorsal flexion, and it tenses when it is on a plantar flexion. However, the inferior fascicle, the arciform fibers and the calcaneofibular ligament, the described ligament complex, are extra-articular structures and are isometric, so that they are always taut”, concludes Maria Cristina Manzanares.”
