Plantar fasciitis is that pain in the bottom of your foot usually in the heel. That pain hurts especially with the first few steps in the morning as you get out of bed. This strange name comes from: “Plantar” means something that belongs to the foot, “fascia” means a band or ligament or a connective tissue, and “itis” means inflammation. You can see in the picture the plantar fascia band as it runs along the foot. This band connects your heel bone to the toes.
The most frequent cause is an abnormal motion of the foot called excessive pronation. Normally, while walking or during long distance running, your foot will strike the ground on the heel, then roll forward toward your toes and inward to the arch. Your arch should only dip slightly during this motion. If it lowers too much, you have what is known as excessive pronation. For more details on pronation, please see the section on biomechanics and gait. Clinically not only those with low arches, but those with high arches can sometimes have plantar fasciitis. The mechanical structure of your feet and the manner in which the different segments of your feet are linked together and joined with your legs has a major impact on their function and on the development of mechanically caused problems. Merely having “flat feet” won’t take the spring out of your step, but having badly functioning feet with poor bone alignment will adversely affect the muscles, ligaments, and tendons and can create a variety of aches and pains. Excess pronation can cause the arch of your foot to stretch excessively with each step. It can also cause too much motion in segments of the foot that should be stable as you are walking or running. This “hypermobility” may cause other bones to shift and cause other mechanically induced problems.
The most common symptoms of plantar fasciitis include pain on the bottom of the foot near the heel, pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking. Greater pain after (not during) exercise or activity.
Your doctor will check your feet and watch you stand and walk. He or she will also ask questions about your past health, including what illnesses or injuries you have had. Your symptoms, such as where the pain is and what time of day your foot hurts most. How active you are and what types of physical activity you do. Your doctor may take an X-ray of your foot if he or she suspects a problem with the bones of your foot, such as a stress fracture.
Non Surgical Treatment
Night splints are treatment that can help stretch your calf and the arch of your foot. Night splints are a type of brace that holds your foot in a flexed position and lengthens the plantar fascia and Achilles tendon overnight. This can prevent morning pain and stiffness. Special orthotics, or arch supports, for your shoes may help alleviate some of the pain by distributing pressure, and can prevent further damage to the plantar fascia. A boot cast may be used to immobilize your foot and reduce strain while the plantar fascia heals. A boot cast looks like a ski boot and can be removed for bathing.
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
