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.
Training on improper, hard and/or irregular surfaces as well as excessive track work in spiked shoes, or steep hill running, can stress the plantar fascia past its limits of elasticity, leading to injury. Finally, failure in the early season to warm up gradually gives the athlete insufficient time for the structures of the foot to re-acclimate and return to a proper fitness level for intensive exercise. Such unprepared and repeated trauma causes microscopic tearing, which may only be detected once full-blown plantar fasciitis and accompanying pain and debilitation have resulted. If the level of damage to the plantar fascia is significant, an inflammatory reaction of the heel bone can produce spike-like projections of new bone, known as heel spurs. Indeed, plantar fasciitis has occasionally been refereed to as heel spur syndrome, though such spurs are not the cause of the initial pain but are instead a further symptom of the problem. While such spurs are sometimes painless, in other cases they cause pain or disability in the athlete, and surgical intervention to remove them may be required. A dull, intermittent pain in the heel is typical, sometimes progressing to a sharp, sustained discomfort. Commonly, pain is worse in the morning or after sitting, later decreasing as the patient begins walking, though standing or walking for long periods usually brings renewal of the pain.
Symptoms of plantar fasciitis can occur suddenly or gradually. When they occur suddenly, there is usually intense heel pain on taking the first morning steps, known as first-step pain. This heel pain will often subside as you begin to walk around, but it may return in the late afternoon or evening. When symptoms occur gradually, a more long-lasting form of heel pain will cause you to shorten your stride while running or walking. You also may shift your weight toward the front of the foot, away from the heel.
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot, this could be a sign of nerve damage in your feet and legs (peripheral neuropathy) your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above – these could be signs of a bone infection, you have stiffness and swelling in your heel, this could be a sign of arthritis. Possible further tests may include blood tests, X-rays – where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
Non Surgical Treatment
The following self-help treatments have been found to be most effective. Rest your foot. Reduce the amount of weight-bearing activities you participate in. Get off of your feet and elevate them. This will allow healing to begin. Apply ice to your foot. Applications of ice packs that provide a comfortable cooling to the heel and arch (not a freezing cold) will help reduce pain, swelling, and inflammation. Apply the ice to the heel and arch (not the toes). Make sure it is comfortable, and leave on your foot for about 20 minutes, 3 times a day. If you have any medical problems such as diabetes, poor circulation, etc., discuss the use of ice with your doctor before applying the ice. ActiveWrap allows you to apply comfortable cold therapy to your foot without messy ice cubes. Use while on the “go.” Do not walk with bare feet. Always protect your heels, arches, and plantar fascia with good supportive shoes. Orthaheel Orthotic Flip Flops For Men and Women are designed for walking comfort with built in orthotic footbeds that help reduce foot pain from plantar fasciitis. Use in the house or on the beach. Stretch the Plantar Fascia while sleeping. Plantar Fasciitis and Heel Spur pain is usually worse with the first steps in the morning. This is due to the Plantar Fascia tightening up, or contracting while we sleep. To prevent these pain producing contractures of the plantar fascia, the foot must be held in its normal or neutral position while we sleep. This optimal position of the foot is maintained with our comfortable and supportive Night Splint. When foot contractures are prevented during sleep, the “first step pains” Plantar Fasciitis and Heel Spurs will gradually subside. Stretch the Plantar Fascia during the day. Even though the Plantar Fascia is a thick tissue band with very little “give” to it, with the proper care (a Night Splint and the following exercises) it can be stretched a small amount. By stretching the Plantar Fascia even a bit, its abnormal pull on the heel is reduced. This will help to reduce pain and inflammation in the heel and arch. Two of the most effective exercises recommended are. Before stepping down, especially after sleeping or resting, stretch the arch of the foot by stretching your legs out in front of you (do not bend the knee). Place a towel around the ball of the foot. Slowly pull on the ends of the towel, pulling the toes and ball of the foot back as far as is comfortable. Hold the foot in this position for ten seconds. Repeat at least ten times. You should feel a pull on the bottom of the foot, especially in the arch. This stretches the plantar fascia, and reduces its pull on the heel. Stand about 2 to 3 feet from a wall. Lean forward with your hands against the wall. With the painful foot behind, place the other foot forward. Press against the wall, shifting weight over the front foot, while straightening the back leg. Keep the heel of the back foot on the floor and feel the stretch in the heel, Achilles tendon, and calf. Hold this position for ten seconds. Repeat at least ten times, and try to do this three times a day. When these things are achieved, the inflammation and pain of Plantar Fasciitis and Heel Spurs will gradually subside. If you are unsure of the nature of your foot problem, if your pain is intense and does not subside, if you are a diabetic or have other medical problems, if your pain is due to an injury, if an open sore is present, if a mass can be felt, or if you think that you may have an infection, we suggest that before beginning any of the above treatments you consult with your doctor.
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.
