Plantar fascitis is the most prevalent cause of pain in inferior part of the heel and includes about 11-15% of all causes of foot pain which require treatment. Plantar fascitis or calcaneal spur is a degenerative syndrome of plantar fascia and in 50% of cases accompanies calcium precipitation at the attachment site to the heel bone (calcaneous), hence it is called heel spur. According to most authors, partial rupture of this fascia and chronic inflammation at the attachment site to the bone leads to the emergence of symptoms. However, other etiologies have been proposed such as being overweight, specific occupations, anatomic variations in the foot, biomechanic problem in the foot, and wearing inappropriate shoes. This disease is most commonly reported among females between 40-60 years old, and has no significant association with socioeconomic status. Patients experience annoying symptoms and make them refer to clinics frequently. Specific and defined symptoms of this syndrome includes plantar pain especially in the medial and inferior parts of the heel which exists during standing up from chair or bed in the first few steps and then decreases.
