Foot and ankle
There are 28 bones and more than 30 joints in the foot. Tough bands of tissue, called ligaments, keep the bones and joints in place. If arthritis develops in one or more of these joints, balance and walking may be affected.
What are the most prevalent foot and ankle conditions?
Arthritis of the Foot and Ankle
Arthritis is the leading cause of disability in the United States. It can occur at any age, and literally means "pain within a joint." As a result, arthritis is a term used broadly to refer to a number of different conditions. Although there is no cure for arthritis, there are many treatment options available. It is important to seek help early so that treatment can begin as soon as possible. With treatment, people with arthritis are able to manage pain, stay active, and live fulfilling lives, often without surgery. The three types of arthritis are:
- Osteoarthritis, also known as degenerative or "wear and tear" arthritis, is a common problem for many people after they reach middle age. Over the years, the smooth, gliding surface covering the ends of bones (cartilage) becomes worn and frayed. This results in inflammation, swelling, and pain in the joint. Osteoarthritis progresses slowly and the pain and stiffness it causes worsens over time.
- Rheumatoid arthritis is a system-wide disease, unlike osteoarthritis which follows a predictable pattern in certain joints . It is an inflammatory disease where the patient's own immune system attacks and destroys cartilage.
- Post-Traumatic Arthritis can develop after an injury to the foot or ankle. This type of arthritis is similar to osteoarthritis and may develop years after a fracture, severe sprain, or ligament injury.
Every mile you walk puts 60 tons of stress on each foot. Your feet can handle a heavy load, but too much stress pushes them over their limits. When you pound your feet on hard surfaces playing sports or wear shoes that irritate sensitive tissues, you may develop heel pain, the most common problem affecting the foot and ankle. A sore heel will usually get better on its own without surgery if you give it enough rest. However, many people try to ignore the early signs of heel pain and keep on doing the activities that caused it. When you continue to use a sore heel, it will only get worse and could become a chronic condition leading to more problems. Surgery is rarely necessary.
Achilles tendinitis is a common condition that causes pain along the back of the leg near the heel. The Achilles tendon is the largest tendon in the body. It connects your calf muscles to your heel bone and is used when you walk, run, and jump. Although the Achilles tendon can withstand great stresses from running and jumping, it is also prone to tendinitis, a condition associated with overuse and degeneration. Simply defined, tendinitis is inflammation of a tendon. Inflammation is the body's natural response to injury or disease, and often causes swelling, pain, or irritation. There are two types of Achilles tendinitis, based upon which part of the tendon is inflamed.
A sprained ankle is a very common injury. Approximately 25,000 people experience it each day. A sprained ankle can happen to athletes and non-athletes, children and adults. It can happen when you take part in sports and physical fitness activities. It can also happen when you simply step on an uneven surface, or step down at an angle. The ligaments of the ankle hold the ankle bones and joint in position. They protect the ankle joint from abnormal movements-especially twisting, turning, and rolling of the foot. A ligament is an elastic structure. Ligaments usually stretch within their limits, and then go back to their normal positions. When a ligament is forced to stretch beyond its normal range, a sprain occurs. A severe sprain causes actual tearing of the elastic fibers.
The term "shin splints" refers to pain and tenderness along or just behind the inner edge of the tibia, the large bone in the lower leg. Shin splints--or medial tibial stress syndrome as it is called by orthopaedists--usually develops after physical activity, such as vigorous exercise or sports. Repetitive activity leads to inflammation of the muscles, tendons, and periosteum (thin layer of tissue covering a bone) of the tibia, causing pain. The bone tissue itself is also involved.
How are foot and ankle injuries treated?
Most sprains and strains are initially treated with rest, ice, compression, and elevation. Moderate and severe sprains and strains are often immobilized with a cast or splint. Severe fractures often require surgical repair.
No one is immune to sprains and strains, but here are some tips developed by the American Academy of Orthopaedic Surgeons to help reduce your injury risk:
- Participate in a conditioning program to build muscle strength
- Do stretching exercises daily
- Always wear properly fitting shoes
- Nourish your muscles by eating a well-balanced diet
- Warm up before any sports activity, including practice
- Use or wear protective equipment appropriate for that sport
