The ankle joint presents an interesting dichotomy of strength and weakness. Whereas the ankle joint supports your body weight while managing sharp twists and turns and also prevent falls, it simultaneously can be weak and highly susceptible to sprains, strains, and even fractures from the simplest of movements, such as stepping off a curb.
The healing process seems simple enough with what is known as the RICE principle (Rest, Ice, Compression & Elevation), and of course there is also often simultaneous use of an ankle brace or tape while performing activity. However, not all ankle trauma follows this roadmap to recovery and healing and when an ankle continues to demonstrate pain for longer than the typical expected healing time period, misdiagnosis may be worth consideration. In particular, as I describe here, perhaps it may be a fracture of the os trigonum.
