Patient: I twisted my right ankle playing soccer 3 years ago. At that time, I visited a famous orthopedic hospital in Beijing, and after the doctor took an x-ray, he said the bone was fine and prescribed some internal and external medicine and went back. There was no big problem with the lateral ankle pressure pain. If the road is uneven, the right foot is more likely to be twisted. Answer: There are three main ligaments on the outside of the ankle: the anterior talofibular ligament, the heel-fibular ligament and the posterior talofibular ligament. The most common injury is to the anterior talofibular ligament, which causes pressure pain on the anterior side of the outer ankle tip. Most anterior talofibular ligament injuries can be treated conservatively with satisfactory results. The heel-fibular ligament is the main ligament that controls the inversion of the ankle joint. If the heel-fibular ligament is injured, it needs to be taken seriously, and untimely early treatment can cause ankle instability and easy sprain of the ankle when walking on uneven paths. General MRI examination shows better for the anterior talofibular ligament. For the heel-fibular ligament, it is difficult to diagnose the nature of the injury due to the angle of the scan. A special MRI imaging sequence is usually required. Persistent pain after ankle injury does not exclude cartilage injury and synovial lesions, and MRI is needed to exclude both conditions.
