To find out where this condition gets its name, we need to look at a specific area of the foot. Your foot is made up of bones, muscles, tendons, and ligaments. The plantar fascia is a relatively inflexible, strong, fibrous band on the bottom of the foot that supports the arch of your foot. Beginning at the heel bone, the plantar fascia extends the length of your foot to connect with your toes at the ball of the foot. When you walk, your weight is distributed across your feet. Any imbalances in the mechanics of your foot and distribution of weight can potentially cause pain. Diseases involving inflammation end with "itis." This explains the name of the condition as being an inflammation of the plantar fascia, thus plantar fasciitis. Repetitive movements such as walking or running stretch the plantar fascia. Because it is not very flexible, this can cause small tears in the fascia, which leads to inflammation and pain. Other factors such as high arches, fallen arches, or a change in the walking surface contribute to the stress placed on the plantar fascia and heel.
Plantar fasciitis is caused by drastic or sudden increases in mileage, poor foot structure, and inappropriate running shoes, which can overload the plantar fascia, the connective tissue that runs from the heel to the base of the toes. The plantar fascia may look like a series of fat rubber bands, but it's made of collagen, a rigid protein that's not very stretchy. The stress of overuse, overpronation, or overused shoes can rip tiny tears in it, causing pain and inflammation, a.k.a. plantar fasciitis.
Symptoms of the plantar fasciitis include a gradual onset of pain under the heel which may radiate into the foot. Tenderness is usually felt under and on the inside of the heel which is initially worse first in the morning but eases as the foot warms up only to return later in the day or after exercise. Stretching the plantar fascia may be painful.
A physical exam performed in the office along with the diagnostic studies as an x-ray. An MRI may also be required to rule out a stress fracture, or a tear of the plantar fascia. These are conditions that do not normally respond to common plantar fasciitis treatment.
Non Surgical Treatment
Plantar fasciitis is usually controlled with conservative treatment. Following control of the pain and inflammation an orthotic (a custom made shoe insert) will be used to stabilize your foot and prevent a recurrence. Over 98% of the time heel spurs and plantar fasciitis can be controlled by this treatment and surgery can be avoided. The orthotic prevents excess pronation and prevents lengthening of the plantar fascia and continued tearing of the fascia. Usually a slight heel lift and a firm shank in the shoe will also help to reduce the severity of this problem. The office visit will be used for careful examination and review to distinguish plantar fasciitis and plantar heel pain syndrome from other problems, many of which are outlined below. It is important to distinguish between a stress reaction of the calcaneus and plantar fasciitis. A feature of many calcaneal stress fractures is pain on lateral and medial compression of the calcaneus.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
