Plantar fasciitis: Inflammation of the plantar fascia, the bowstring-like tissue that stretches from the heel bone to the base of the toes. Plantar fasciitis can be due to calcaneal spurs, which typically cause localized tenderness and pain that is made worse by stepping down on the heel. Plantar fasciitis may be related to physical activity overload, abnormal foot mechanics, or may be due to underlying diseases that cause arthritis, such as Reiter disease, ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. Treatment is designed to decrease inflammation and avoid reinjury. Icing reduces pain and inflammation. Anti-inflammatory agents, such as ibuprofen and injections of cortisone, can help. Infrequently, surgery is done on chronically inflamed spurs. A donut-shaped shoe insert can take pressure off a calcaneal spur and lessen plantar fasciitis.
Plantar fasciitis is common in sports which involve running, dancing or jumping. Runners who overpronate where their feet roll in or flatten too much are particularly at risk the plantar fascia is over stretched as the foot flattens. A common factor is tight calf muscles which lead to a prolonged or high velocity pronation or rolling in of the foot. This in turn produces repetitive over-stretching of the plantar fascia leading to possible inflammation and thickening of the tendon. As the fascia thickens it looses flexibility and strength. Other causes include either a low arch called pes planus or a very high arched foot known as pes cavus. Assessing the foot for plantar fasciitisExcessive walking in footwear which does not provide adequate arch support has been attributed. Footwear for plantar fasciitis should be flat, lace-up and with good arch support and cushioning. Overweight individuals are more at risk of developing plantar fasciitis due to the excess weight impacting on the foot.
The major complaint of those with plantar fasciitis is pain and stiffness in the bottom of the heel. This develops gradually over time. It usually affects just one foot, but can affect both feet. Some people describe the pain as dull, while others experience a sharp pain, and some feel a burning or ache on the bottom of the foot extending outward from the heel. The pain is usually worse in the morning when you take your first steps out of bed, or if you’ve been sitting or lying down for a while. Climbing stairs can be very difficult due to the heel stiffness. After prolonged activity, the pain can flare-up due to increased inflammation. Pain is not usually felt during the activity, but rather just after stopping.
Your doctor can usually diagnose plantar fasciitis just by talking to you and examining your feet. Rarely, tests are needed if the diagnosis is uncertain or to rule out other possible causes of heel pain. These can include X-rays of the heel or an ultrasound scan of the fascia. An ultrasound scan usually shows thickening and swelling of the fascia in plantar fasciitis.
Non Surgical Treatment
The plantar fascia is a band of tissue, much like a tendon, that starts at your heel and goes along the bottom of your foot. It attaches to each one of the bones that form the ball of your foot. The plantar fascia works like a rubber band between the heel and the ball of your foot to form the arch of your foot. If the band is short, you'll have a high arch, and if it's long, you'll have a low arch, what some people call flatfeet. A pad of fat in your heel covers the plantar fascia to help absorb the shock of walking. Damage to the plantar fascia can be a cause of heel pain.
Most practitioners agree that treatment for plantar fasciitis is a slow process. Most cases resolve within a year. If these more conservative measures don't provide relief after this time, your doctor may suggest other treatment. In such cases, or if your heel pain is truly debilitating and interfering with normal activity, your doctor may discuss surgical options with you. The most common surgery for plantar fasciitis is called a plantar fascia release and involves releasing a portion of the plantar fascia from the heel bone. A plantar fascia release can be performed through a regular incision or as endoscopic surgery, where a tiny incision allows a miniature scope to be inserted and surgery to be performed. About one in 20 patients with plantar fasciitis will need surgery. As with any surgery, there is still some chance that you will continue to have pain afterwards.
More than with most sports injuries, a little bit of prevention can go a long way toward keeping you free from plantar fasciitis. Here are some tips to follow. Wear supportive shoes that fit you well. When your shoes start to show wear and can no longer give your feet the support they need, it's time to get a new pair. Runners should stop using their old shoes after about 500 miles of use. Have a trained professional at a specialty running store help you find the right pair for your foot type, and then keep your shoes tied and snug when you wear them. Stay in good shape. By keeping your weight in check, you'll reduce the amount of stress on your feet. Stretch your calves and feet before you exercise or play a sport. Ask an athletic trainer or sports medicine specialist to show you some dynamic stretching exercises. Start any new activity or exercise slowly and increase the duration and intensity of the activity gradually. Don't go out and try to run 10 miles the first time you go for a jog. Build up to that level of exercise gradually. Talk to your doctor about getting heel pads, custom shoe inserts, or orthotics to put in your shoes. Foot supports can help cushion your feet and distribute your weight more evenly. This is especially true for people with high arches or flat feet. Your doctor will be able to tell you if shoe inserts and supports might lower your chances of heel injury.
