The most common injury in all of sports is a lateral ankle ligament sprain. These injuries can vary from mild to quite severe. Minor injuries can be treated with rest, ice and compression. If the symptoms do not abate in a few days, evaluation by a medical provider can be necessary. Ninety percent of ankle sprains go on to heal without surgical intervention. However, if there is continued pain after a few days with swelling and instability, an evaluation is warranted.
In terms of prevention, working on resisted inversion and eversion of the foot to strengthen the muscles on the inside and outside of the ankle can help prevent ankle sprains. This can be done with a towel or an elastic resistance band. It is also important to strengthen the core as well as the entire lower extremity. This has been shown to prevent ankle injuries in both recreational and high-level athletes.
