Ankle Sprains
Symptoms and Signs of Ankle Sprains
Ankle sprains cause pain, swelling, and sometimes muscle spasms. The location of pain and swelling varies with the type of injury: Inversion sprains: Usually maximal at the anterolateral ankle Eversion injuries: Maximal over the deltoid ligament Maisonneuve fracture: Over the proximal fibula as well as the medial and sometimes lateral ankle Third-degree sprains (complete tears, often involving both medial and lateral ligaments): Often diffuse (sometimes the ankle appears egg-shaped) Generally, tenderness is maximal over the damaged ligaments rather than over the bone; tenderness that is greater over bone than over ligaments suggests fracture. Inmild (1st-degree) ankle sprains,the pain and swelling are minimal, but the ankle is weakened and prone to reinjury. Healing takes hours to days. Inmoderate to severe (2nd-degree) ankle sprains,the ankle is often swollen and bruised; walking is painful and difficult. Healing takes days to weeks. Invery severe (3rd-degree) ankle sprains,the whole ankle may be swollen and bruised. The ankle is unstable and cannot bear weight. Nerves may also be damaged. Articular cartilage may be torn, resulting in long-term pain, swelling, joint instability, early arthritis, and occasionally gait abnormalities. Healing of very severe ankle sprains usually takes 6 to 8 weeks.
