Plantar fasciitis is one of the most common sources of heel pain. Your plantar fascia is a thick fibrous band of connective tissue originating on the bottom surface of the calcaneus (heel bone) and
extending along the sole of the foot towards the toes. Your plantar fascia acts as a passive limitation to the over flattening of you arch. When your plantar fascia develops micro tears or becomes
inflammed it is known as plantar fasciitis.
Under normal circumstances, your plantar fascia acts like a shock-absorbing bowstring, supporting the arch in your foot. If tension on that bowstring becomes too great, it can create small tears in
the fascia. Repetitive stretching and tearing can cause the fascia to become irritated or inflamed.
When a patient has plantar fasciitis, the connective tissue that forms the arch of the foot becomes inflamed (tendonitis) and degenerative (tendinosis)--these abnormalities cause plantar fasciitis
and can make normal activities quite painful. Symptoms of plantar fasciitis are typically worsened early in the morning after sleep. At that time, the arch tissue is tight and simple movements
stretch the contracted tissue. As you begin to loosen the foot, the pain usually subsides, but often returns with prolonged standing or walking.
Plantar fasciitis is usually diagnosed by your physiotherapist or sports doctor based on your symptoms, history and clinical examination. After confirming your plantar fasciitis they will investigate
WHY you are likely to be predisposed to plantar fasciitis and develop a treatment plan to decrease your chance of future bouts. X-rays may show calcification within the plantar fascia or at its
insertion into the calcaneus, which is known as a calcaneal or heel spur. Ultrasound scans and MRI are used to identify any plantar fasciitis tears, inflammation or calcification. Pathology tests
(including screening for HLA B27 antigen) may identify spondyloarthritis, which can cause symptoms similar to plantar fasciitis.
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 unusual cases, surgical intervention is necessary for relief of pain. These should only be employed after non-surgical efforts have been used without relief. Generally, such surgical procedures
may be completed on an outpatient basis in less than one hour, using local anesthesia or minimal sedation administrated by a trained anesthesiologist. In such cases, the surgeon may remove or release
the injured and inflamed fascia, after a small incision is made in the heel. A surgical procedure may also be undertaken to remove bone spurs, sometimes as part of the same surgery addressing the
damaged tissue. A cast may be used to immobilize the foot following surgery and crutches provided in order to allow greater mobility while keeping weight off the recovering foot during healing. After
removal of the cast, several weeks of physical therapy can be used to speed recovery, reduce swelling and restore flexibility.
Stretching exercises for the Achilles tendon and plantar fascia are recommend to relieve pain and aid in the healing process. Sometimes application of athletic tape is recommended. In moderate or
severe cases of plantar fasciitis, your doctor may recommend you wearing a night splint, which will stretch the arch of your foot and calf while you sleep. This helps to lengthen the Achilles tendon
and plantar fascia for symptom relief. Depending on the severity of your plantar fasciitis, your physician may prescribe a store-bought orthotic (arch support) or custom-fitted orthotic to help
distribute your foot pressure more evenly.
