Cause

A sprain occurs when one or more of the ligaments stabilizing the ankle joint become stretched to varying degrees. In the vast majority of cases this tends to result from a forced internal twisting movement of the foot. When the ligaments are stretched beyond their limit, they may partially or completely tear.

Treatment

The treatment of a sprain most commonly involves following an immobilization protocol with a splint or brace, and complying with RICE principles: rest, ice, compression, elevation. If the ankle has residual instability, an in-depth examination will be performed to determine whether a different treatment, whether conservative or operative, should be considered.
