Plantar fasciitis is a common painful disorder affecting the heel and underside of the foot. It is a disorder of the insertion site of plantar fascia on the bone and is characterized by scarring, inflammation, or structural breakdown of the footâs plantar fascia. It is often caused by overuse injury of the plantar fascia, increases in exercise, weight or age. Although plantar fasciitis was originally thought to be an inflammatory process, newer studies have demonstrated structural changes more consistent with a degenerative process. As a result of this new observation, many in the academic community have stated the condition should be renamed plantar fasciosis.
Your plantar fascia (fay-sha) supports the arch of your foot as you run or walk. It is a thick, inelastic, fibrous band that starts in your heel, runs along the bottom of your foot, and spreads out to your toes. Plantar fasciitis is an inflammation of this fibrous band. If you are female or have a job that requires a lot of walking or standing on hard surfaces you are more at risk for plantar fasciitis. Additional causes include Being overweight, Having flat feet or high arches, Wearing shoes with poor support, Walking or running for exercise, Tight calf muscles that limit how far you can flex your ankles, Running on soft terrain, Increase in activity level, Genetic predisposition.
Heel pain is the most common symptom associated with plantar fasciosis. Your heel pain may be worse in the morning or after you have been sitting or standing for long periods. Pain is most common under your heel bone, but you also may experience pain in your foot arch or on the outside aspect of your foot. Other common signs and symptoms of plantar fasciosis include mild swelling and redness in your affected area, tenderness on the bottom of your heel, impaired ability to ambulate.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
Many types of treatment have been used to combat plantar fasciitis, including injections, anti-inflammatory medications, orthotics, taping, manipulation, night splinting, and instrument-assisted soft-tissue manipulation (IASTM). IASTM begins with heat, followed by stretching. Stretching may be enhanced by applying ice to the plantar fascia. These stretches should be performed several times per day, with the calf in the stretched position. IASTM uses stainless-steel instruments to effectively access small areas of the foot. IASTM is believed to cause a secondary trauma to injured soft tissues as part of the healing process. Therapeutic modalities such as low-level laser, ultrasound, and electrical muscular stimulation may be effective in the reduction of pain and inflammation. Low Dye strapping or taping of the foot is an essential part of successful treatment of plantar fasciitis. Extracorporeal shock-wave therapy (ESWT) was introduced with great promise at one time. Recent studies have reported less favorable results. Some report no effect. Previous local steroid injection may actually have a negative effect on results from ESWT.
In cases that do not respond to any conservative treatment, surgical release of the plantar fascia may be considered. Plantar fasciotomy may be performed using open, endoscopic or radiofrequency lesioning techniques. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. Potential risk factors include flattening of the longitudinal arch and heel hypoesthesia as well as the potential complications associated with rupture of the plantar fascia and complications related to anesthesia.
Every time your foot strikes the ground, the plantar fascia is stretched. You can reduce the strain and stress on the plantar fascia by following these simple instructions: Avoid running on hard or uneven ground, lose any excess weight, and wear shoes and orthotics that support your arch to prevent over-stretching of the plantar fascia.
