Definition of Plantar fasciitis:

Plantar fasciitis is inflammation of the thick tissue on the bottom of the foot. This tissue is called the plantar fascia. It connects the heel bone to the toes and creates the arch of the foot.

Causes, incidence, and risk factors:

Plantar fasciitis occurs when the thick band of tissue on the bottom of the foot is overstretched or overused. This can be painful and make walking more difficult.

Risk factors for plantar fasciitis include:

• Foot arch problems (both flat feet and high arches)
• Obesity or sudden weight gain
• Long-distance running, especially running downhill or on uneven surfaces
• Sudden weight gain
• Tight Achilles tendon (the tendon connecting the calf muscles to the heel)
• Shoes with poor arch support or soft soles

Plantar fasciitis most often affects active men ages 40 - 70. It is one of the most common orthopedic complaints relating to the foot.

Plantar fasciitis is commonly thought of as being caused by a heel spur, but research has found that this is not the case. On x-ray, heel spurs are seen in people with and without plantar fasciitis.
