Causes and grades of sprained Ankles


According to orthopedic surgeons, over 25,000 cases of sprained injuries occur every day. Twisting, turning and other abnormal movements can cause a sprain ankle. A sprained ankle can occur by only missing a step when using the stairs or participation in a certain sport. It can happen to a person of any age, an athlete or non-athlete or even a well-balanced person.

There are several types of ankle sprains. A sprain that occurs when the foot is twisted inside is known as inversion sprain. Eversion sprains occur when the deltoid ligament is twisted outward but is less common. High ankle sprains are caused by the outward twisting of the ankle and the foot which is also a less common case. When a fracture is engaged, it is said to be medial ligament sprains. During this sprain, ligaments on the inside of the ankle are damaged.

So many factors can bring about sprain ankles. These factors are congenital anomalies, post traumatic arthritis, Osteochondritisdissecans which occurs when a bit of bone in the joint, a fracture that was never diagnosed in the past, syndesmtis ligament injuries and functional instability.

There are three grades of sprained ankle which are determined by the severity, amounts of swelling, levels of pain and range of motion. In grade 1, the pain felt is very mild. The ligaments receive some stretching, slight tearing, very little or absolutely no pain, swelling, inflexibility or straining during walking. In grade 2, there is a bit more pain than in grade 1. In this grade you experience some instability in the joint, bruising, distension, instability stiffness, slight to severe pains and difficulty in walking. In grade 3 this is where a person experiences the worst type of ankle sprain. This stage involves severe swelling, extensive bruising. The pains are so unbearable initially but as time goes by the pain will disappear gradually.
