Plantar fasciitis refers to an inflammation of the plantar fascia, a thick, fibrous band running along the sole of the foot. Such inflammation results from direct injury to the plantar fascia, usually, repeated trauma to the tissue where the fascia attaches to the calcaneus or heel bone. The plantar fascia is critical in maintaining the foot’s complex arch system, also playing a role in balance and fine control of certain phases of the athlete’s gait. Injury to the plantar fascia is particularly painful and disabling for runners and can often prove stubbornly resistant to treatment. Rehabilitation is frequently a lengthy and frustrating process. For these reasons, care should be taken where possible to avoid such injury by means of preventative exercises and sensitivity to early warning signs.
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.
Plantar fasciosis is characterized by pain at the bottom of the heel with weight bearing, particularly when first arising in the morning; pain usually abates within 5 to 10 min, only to return later in the day. It is often worse when pushing off of the heel (the propulsive phase of gait) and after periods of rest. Acute, severe heel pain, especially with mild local puffiness, may indicate an acute fascial tear. Some patients describe burning or sticking pain along the plantar medial border of the foot when walking.
Plantar fasciosis is confirmed if firm thumb pressure applied to the calcaneus when the foot is dorsiflexed elicits pain. Fascial pain along the plantar medial border of the fascia may also be present. If findings are equivocal, demonstration of a heel spur on x-ray may support the diagnosis; however, absence does not rule out the diagnosis, and visible spurs are not generally the cause of symptoms. Also, infrequently, calcaneal spurs appear ill defined on x-ray, exhibiting fluffy new bone formation, suggesting spondyloarthropathy (eg, ankylosing spondylitis, reactive arthritis. If an acute fascial tear is suspected, MRI is done.
Non Surgical Treatment
No single treatment works best for everyone with plantar fasciitis. But there are many things you can try to help your foot get better. Give your feet a rest. Cut back on activities that make your foot hurt. Try not to walk or run on hard surfaces. To reduce pain and swelling, try putting ice on your heel. Or take an over-the-counter pain reliever like ibuprofen (such as Advil or Motrin) or naproxen (such as Aleve). Do toe stretches , calf stretches and towel stretches several times a day, especially when you first get up in the morning. (For towel stretches, you pull on both ends of a rolled towel that you place under the ball of your foot.) Get a new pair of shoes. Pick shoes with good arch support and a cushioned sole. Or try heel cups or shoe inserts ( orthotics ). Use them in both shoes, even if only one foot hurts. If these treatments do not help, your doctor may recommend splints that you wear at night, shots of medicine (such as a steroid ) in your heel, or other treatments. You probably will not need surgery. Doctors only suggest it for people who still have pain after trying other treatments for 6 to 12 months.
Most studies indicate that 95% of those afflicted with plantar fasciitis are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don't improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. While the success rate is very high following surgery, one should be aware that there is often a prolonged postoperative period of discomfort similar to the discomfort experienced prior to surgery. This pain usually will abate within 2-3 months. One should always be sure to understand all the risks associated with any surgery they are considering.
