The plantar fascia is a thick band of connective tissue that runs along the underneath of the foot from the heel bone to the toes. At the heel it can also have fascial connections to the achilles tendon. Its job is to maintain the arch of the foot, it acts as a bowstring pulled between the heel and the toes. "Itis" as a suffix indicates inflammation, but with the plantar fascia there is still some controversy over what exactly happens to the tissue when it becomes painful.
You're more likely to develop the condition if you're female, overweight or have a job that requires a lot of walking or standing on hard surfaces. You're also at risk if you walk or run for exercise, especially if you have tight calf muscles that limit how far you can flex your ankles. People with very flat feet or very high arches also are more prone to plantar fasciitis.
Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually worst with the first few steps after awakening, although it can also be triggered by long periods of standing or getting up from a seated position.
Your doctor can usually diagnose plantar fasciitis just by talking to you and examining your feet. Rarely, tests are needed if the diagnosis is uncertain or to rule out other possible causes of heel pain. These can include X-rays of the heel or an ultrasound scan of the fascia. An ultrasound scan usually shows thickening and swelling of the fascia in plantar fasciitis.
Non Surgical Treatment
Most health care providers agree that initial treatment for plantar fasciitis should be quite conservative. You'll probably be advised to avoid any exercise that is making your pain worse. Your doctor may also advise one or more of these treatment options. A heel pad. In plantar fasciitis, a heel pad is sometimes used to cushion the painful heel if you spend a great deal of time on your feet on hard surfaces. Also, over-the-counter or custom-made orthotics, which fit inside your shoes, may be constructed to address specific imbalances you may have with foot placement or gait. Stretching: Stretching exercises performed three to five times a day can help elongate the heel cord. Ice: You may be advised to apply ice packs to your heel or to use an ice block to massage the plantar fascia before going to bed each night. Pain relievers: Simple over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, are often helpful in decreasing inflammation and pain. If you have stomach trouble from such drugs, your health care provider may prescribe an alternative. A night splint: A night splint is sometimes used to hold your foot at a specific angle, which prevents the plantar fascia from shortening during sleep. Ultrasound: Ultrasound therapy can be performed to decrease inflammation and aid healing. Steroid injections: Anti-inflammatory steroid injections directly into the tissue around your heel may be temporarily helpful. However, if these injections are used too many times, you may suffer other complications, such as shrinking of the fat pad of your heel, which you need for insulation. Loss of the fat pad could actually increase your pain, or could even rupture the plantar fascia in rare cases. Walking cast: In cases of long-term plantar fasciitis unresponsive to usual treatments, your doctor may recommend that you wear a short walking cast for about three weeks. This ensures that your foot is held in a position that allows the plantar fascia to heal in a stretched, rather than shortened, position. Shock wave therapy, Extracorporeal shock wave therapy which may be prescribed prior to considering surgery if your symptoms have persisted for more than six months. This treatment does not involve any actual incisions being made rather it uses a high intensity shock wave to stimulate healing of the plantar fascia.
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.
In one exercise, you lean forward against a wall with one knee straight and heel on the ground. Your other knee is bent. Your heel cord and foot arch stretch as you lean. Hold for 10 seconds, relax and straighten up. Repeat 20 times for each sore heel. It is important to keep the knee fully extended on the side being stretched. In another exercise, you lean forward onto a countertop, spreading your feet apart with one foot in front of the other. Flex your knees and squat down, keeping your heels on the ground as long as possible. Your heel cords and foot arches will stretch as the heels come up in the stretch. Hold for 10 seconds, relax and straighten up. Repeat 20 times. About 90 percent of people with plantar fasciitis improve significantly after two months of initial treatment. You may be advised to use shoes with shock-absorbing soles or fitted with an off-the-shelf shoe insert device like a rubber heel pad. Your foot may be taped into a specific position. If your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medication. If you still have symptoms, you may need to wear a walking cast for two to three weeks or a positional splint when you sleep. In a few cases, surgery is needed for chronically contracted tissue.
