[Progress of diagnosis and treatment in deltoid ligament injuries of ankle].

Deltoid ligament injury is common in the daily activities, unlike some other diseases, mechanism of deltoid ligament injury is relatively clear with less controversies, but the consistent standard for its diagnosis and treatment has not yet formed.
