Plantar fasciitis is a common cause of heel pain in adults. The pain is usually caused by collagen degeneration (which is sometimes misnamed “chronic inflammation”) at the origin of the plantar fascia at the medial tubercle of the calcaneus. This degeneration is similar to the chronic necrosis of tendonosis, which features loss of collagen continuity, increases in ground substance (matrix of connective tissue) and vascularity, and the presence of fibro-blasts rather than the inflammatory cells usually seen with the acute inflammation of tendonitis. The cause of the degeneration is repetitive microtears of the plantar fascia that overcome the body's ability to repair itself.
Plantar fasciitis is one of those injuries that magically seems to appear for no apparent reason. However, plantar fasciitis is caused by one of two methods. They are either traction or compression injuries. Plantar fasciitis is most often associated with impact and running sports, especially those that involve toe running rather than heel running styles. It is also commonly diagnosed in individuals with poor foot biomechanics that stress the plantar fascia. Flat feet or weak foot arch control muscles are two common causes of plantar fasciitis.
Plantar fasciitis sufferers feel a sharp stab or deep ache in the middle of the heel or along the arch. Another sign is the morning hobble from the foot trying to heal itself in a contracted position overnight. Taking that first step causes sudden strain on the bottom of the foot. The pain can recur after long spells of sitting, but it tends to fade during a run, once the area is warmed up.
If you see a doctor for heel pain, he or she will first ask questions about where you feel the pain. If plantar fasciitis is suspected, the doctor will ask about what activities you've been doing that might be putting you at risk. The doctor will also examine your foot by pressing on it or asking you to flex it to see if that makes the pain worse. If something else might be causing the pain, like a heel spur or a bone fracture, the doctor may order an X-ray to take a look at the bones of your feet. In rare cases, if heel pain doesn't respond to regular treatments, the doctor also might order an MRI scan of your foot. The good news about plantar fasciitis is that it usually goes away after a few months if you do a few simple things like stretching exercises and cutting back on activities that might have caused the problem. Taking over-the-counter medicines can help with pain. It's rare that people need surgery for plantar fasciitis. Doctors only do surgery as a last resort if nothing else eases the pain.
Non Surgical Treatment
Treatment of plantar fasciitis begins with first-line strategies, which you can begin at home. Stretching exercises. Exercises that stretch out the calf muscles help ease pain and assist with recovery. Avoid going barefoot. When you walk without shoes, you put undue strain and stress on your plantar fascia. Ice. Putting an ice pack on your heel for 20 minutes several times a day helps reduce inflammation. Place a thin towel between the ice and your heel,do not apply ice directly to the skin. Limit activities. Cut down on extended physical activities to give your heel a rest. Shoe modifications. Wearing supportive shoes that have good arch support and a slightly raised heel reduces stress on the plantar fascia. Medications. Oral nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be recommended to reduce pain and inflammation. If you still have pain after several weeks, see your foot and ankle surgeon, who may add one or more of these treatment approaches. Padding and strapping. Placing pads in the shoe softens the impact of walking. Strapping helps support the foot and reduce strain on the fascia. Orthotic devices. Custom orthotic devices that fit into your shoe help correct the underlying structural abnormalities causing the plantar fasciitis. Injection therapy. In some cases, corticosteroid injections are used to help reduce the inflammation and relieve pain. Removable walking cast. A removable walking cast may be used to keep your foot immobile for a few weeks to allow it to rest and heal. Night splint. Wearing a night splint allows you to maintain an extended stretch of the plantar fascia while sleeping. This may help reduce the morning pain experienced by some patients. Physical therapy. Exercises and other physical therapy measures may be used to help provide relief.
In very rare cases plantar fascia surgery is suggested, as a last resort. In this case the surgeon makes an incision into the ligament, partially cutting the plantar fascia to release it. If a heel spur is present, the surgeon will remove it. Plantar Fasciitis surgery should always be considered the last resort when all the conventional treatment methods have failed to succeed. Endoscopic plantar fasciotomy (EPF) is a form of surgery whereby two incisions are made around the heel and the ligament is being detached from the heel bone allowing the new ligament to develop in the same place. In some cases the surgeon may decide to remove the heel spur itself, if present. Just like any type of surgery, Plantar Fascia surgery comes with certain risks and side effects. For example, the arch of the foot may drop and become weak. Wearing an arch support after surgery is therefore recommended. Heel spur surgeries may also do some damage to veins and arteries of your foot that allow blood supply in the area. This will increase the time of recovery.
The following exercises are commonly prescribed to patients with this condition. You should discuss the suitability of these exercises with your physiotherapist prior to beginning them. Generally, they should be performed 2 - 3 times daily and only provided they do not cause or increase symptoms. Your physiotherapist can advise when it is appropriate to begin the initial exercises and eventually progress to the intermediate and advanced exercises. As a general rule, addition of exercises or progression to more advanced exercises should take place provided there is no increase in symptoms. Calf Stretch with Towel. Begin this stretch in long sitting with your leg to be stretched in front of you. Your knee and back should be straight and a towel or rigid band placed around your foot as demonstrated. Using your foot, ankle and the towel, bring your toes towards your head until you feel a stretch in the back of your calf, Achilles tendon, plantar fascia or leg. Hold for 5 seconds and repeat 10 times at a mild to moderate stretch provided the exercise is pain free. Resistance Band Calf Strengthening. Begin this exercise with a resistance band around your foot as demonstrated and your foot and ankle held up towards your head. Slowly move your foot and ankle down against the resistance band as far as possible and comfortable without pain, tightening your calf muscle. Very slowly return back to the starting position. Repeat 10 - 20 times provided the exercise is pain free.
