There are many diagnoses within the differential of heel pain; however, plantar fasciitis is the most common cause of heel pain for which professional care is sought. Approximately 10% of the United States population experiences bouts of heel pain, which results in 1 million visits per year to medical professionals for treatment of plantar fasciitis. The annual cost of treatments for plantar fasciitis is estimated to be between $192 and $376 million dollars. The etiology of this condition is multifactorial, and the condition can occur traumatically; however, most cases are from overuse stresses.
There are several possible causes of plantar fasciitis, including wearing high heels, gaining weight, increased walking, standing, or stair-climbing. If you wear high-heeled shoes, including western-style boots, for long periods of time, the tough, tendonlike tissue of the bottom of your foot can become shorter. This layer of tissue is called fascia. Pain occurs when you stretch fascia that has shortened. This painful stretching might happen, for example, when you walk barefoot after getting out of bed in the morning. If you gain weight, you might be more likely to have plantar fasciitis, especially if you walk a lot or stand in shoes with poor heel cushioning. Normally there is a pad of fatty tissue under your heel bone. Weight gain might break down this fat pad and cause heel pain. Runners may get plantar fasciitis when they change their workout and increase their mileage or frequency of workouts. It can also occur with a change in exercise surface or terrain, or if your shoes are worn out and don’t provide enough cushion for your heels. If the arches of your foot are abnormally high or low, you are more likely to develop plantar fasciitis than if your arches are normal.
The condition typically starts gradually with mild pain at the heel bone often referred to as a stone bruise. You’re more likely to feel it after (not during) exercise. The pain classically occurs right after getting up in the morning and after a period of sitting. If you don’t treat plantar fasciitis, it may become a chronic condition. You may not be able to keep up your level of activity, and you may develop symptoms of foot, knee, hip and back problems because plantar fasciitis can change the way you walk.
After you describe your symptoms and discuss your concerns, your doctor will examine your foot. Your doctor will look for these signs. A high arch, an area of maximum tenderness on the bottom of your foot, just in front of your heel bone. Pain that gets worse when you flex your foot and the doctor pushes on the plantar fascia. The pain improves when you point your toes down. Limited “up” motion of your ankle. Your doctor may order imaging tests to help make sure your heel pain is caused by plantar fasciitis and not another problem. X-rays provide clear images of bones. They are useful in ruling out other causes of heel pain, such as fractures or arthritis. Heel spurs can be seen on an x-ray. Other imaging tests, such as magnetic resonance imaging (MRI) and ultrasound, are not routinely used to diagnose plantar fasciitis. They are rarely ordered. An MRI scan may be used if the heel pain is not relieved by initial treatment methods.
Non Surgical Treatment
About 80% of plantar fasciitis cases resolve spontaneously by 12 months; 5% of patients end up undergoing surgery for plantar fascia release because all conservative measures have failed. For athletes in particular, the slow resolution of plantar fasciitis can be a highly frustrating problem. These individuals should be cautioned not to expect overnight resolution, especially if they have more chronic pain or if they continue their activities. . Generally, the pain resolves with conservative treatment. Although no mortality is associated with this condition, significant morbidity may occur. Patients may experience progressive plantar pain, leading to limping (antalgic gait) and restriction of activities such as walking and running. In addition, changes in weight-bearing patterns resulting from the foot pain may lead to associated secondary injury to the hip and knee joints.
The most dramatic therapy, used only in cases where pain is very severe, is surgery. The plantar fascia can be partially detached from the heel bone, but the arch of the foot is weakened and full function may be lost. Another surgery involves lengthening the calf muscle, a process called gastrocnemius recession. If you ignore the condition, you can develop chronic heel pain. This can change the way you walk and cause injury to your legs, knees, hips and back. Steroid injections and some other treatments can weaken the plantar fascia ligament and cause potential rupture of the ligament. Surgery carries the risks of bleeding, infection, and reactions to anesthesia. Plantar fascia detachment can also cause changes in your foot and nerve damage. Gastrocnemius resection can also cause nerve damage.
Stretching exercises for the Achilles tendon and plantar fascia are recommend to relieve pain and aid in the healing process. Sometimes application of athletic tape is recommended. In moderate or severe cases of plantar fasciitis, your doctor may recommend you wearing a night splint, which will stretch the arch of your foot and calf while you sleep. This helps to lengthen the Achilles tendon and plantar fascia for symptom relief. Depending on the severity of your plantar fasciitis, your physician may prescribe a store-bought orthotic (arch support) or custom-fitted orthotic to help distribute your foot pressure more evenly.
