A coalition is a technically a connection between two bones that should not be present. Coalitions can be congenital or acquired. When acquired, it is usually due to trauma. But when the diagnosis of a coalition is given around the foot and ankle (the tarsal bones), it infers the congenital variety.
As noted in my prior blog, arthritis will develop if there has been trauma to the ankle, such as with recurrent ankle sprains or with certain types of fractures, and in those who have systematic or inflammatory arthritis.
The gastrocnemius is a muscle that is part of the tricep-surae, the tendon of which, and along with the solus, comprises the Achilles Tendon. The gastrocnemius/Achilles tendon unit is unique in that it crosses two joints; the knee and the ankle
Ankle arthritis, though far less common than hip or knee arthritis, is quite debilitating. The native ankle joint, with its configuration and thicker cartilage will last you your whole life....the ankle is not a “wear and tear” joint.
Ankle sprains are remarkably common. In fact, one can argue that it may be the most common injury in the world. The vast majority of the time someone will “twist” an ankle, have a few days to a week of discomfort, and then return to normal activity. But there are times when this is not the case.
