Psoriasis is a disease that most people think of as primarily a skin disease because the condition causes a persistent rash in various areas of the body. Psoriatic arthritis is a type of joint disease that occurs in roughly seven percent of people who have psoriasis. Psoriatic arthritis affects people of all ages, but most get it between the ages of 30 and 50. Usually a patient has psoriasis (the skin rash) for many years before the arthritis develops, and usually the arthritis comes on slowly, ...

In this guide we are concerned with fractures of the lower leg between the knee and ankle. The two bones in the lower leg are the tibia and fibula. We will limit this discussion to fractures of the shaft, or mid section of these two bones. Fractures of the lower end of the tibia and fibula are covered in ankle fractures. Fractures of the upper end of the tibia are covered in knee fractures.The tibia bone is the largest and most important bone of the lower leg. It is quite vulnerable to injury. T...

An ankle sprain is a common injury and usually results when the ankle is twisted, or turned in (inverted). The term sprain signifies injury to the soft tissues, usually the ligaments, of the ankle.

Pain along the front or inside edge of the shinbone (tibia) is commonly referred to as shin splints. The problem is common in athletes who run and jump. It is usually caused by doing too much, too quickly. The runner with this condition typically reports a recent change in training, such as increasing the usual pace, adding distance, or changing running surfaces. People who haven't run for awhile are especially prone to shin splints after they first get started, especially when they run do...

The peroneals are two muscles and their tendons that attach along the outer edge of the lower leg. The peroneal tendons are enclosed in a fibrous tunnel that runs behind the outside ankle bone (the lateral malleolus). Damage or injury to the structures that form and support this tunnel may lead to a condition in which the peroneal tendons snap out of place. This condition is called peroneal tendon subluxation.

Problems affecting the two peroneal tendons that lie behind the outer ankle bone (the lateral malleolus) are common in athletes. These problems mainly occur in the area where the two tendons glide within a fibrous tunnel behind the lateral malleolus.

Injuries of the ankle joint are common. While ankle fractures and ankle sprains heal pretty well, they can lead to problems much later in life. This is due to the wear and tear that occurs over the years after the injury. This condition is called osteoarthritis (OA) or posttraumatic arthritis. Trauma means injury, and the term posttraumatic arthritis is used to describe arthritis that develops after an injury.

An ankle injury common to athletes is the ankle syndesmosis injury. This type of injury is sometimes called a high ankle sprain because it involves the ligaments above the ankle joint. In an ankle syndesmosis injury, at least one of the ligaments connecting the bottom ends of the tibia and fibula bones (the lower leg bones) is sprained. Recovering from even mild injuries of this type takes at least twice as long as from a typical ankle sprain.

The ankle joint is formed where the bones of the lower leg, the tibia and the fibula, connect above the anklebone, called the talus. The tibia is the main bone of the lower leg. The fibula is the small, thin bone along the outer edge of the tibia.
