Ankle dislocations occur when significant force applied to the joint results in loss of opposition of the articular surfaces. This is a very dramatic injury, often combined with a bone fracture. In an ankle sprain, the normal bony alignment is maintained but the supporting structures called ligaments are stretched or torn. Ankle sprains are common, dislocations are fairly uncommon and an ankle dislocation without a broken bone is very rare. The typical sequence of events in an ankle dislocation would usually involve an urgent trip to the emergency room for x-rays, and then a physician will “reduce” the ankle. This means they will set the alignment back to normal. Surgery is often needed. After setting the dislocated ankle back in place there will be a period of immobilization in a cast or boot that lasts several weeks. This is followed by gradual increases in weight bearing, motion, and strength. Have you ever had a sprained ankle?Â
