The plantar fascia is made up of 3 distinct parts: the medial, central, and lateral bands. The central plantar fascia is the thickest and strongest section, and this segment is also the most likely to be involved with plantar fasciitis. In normal circumstances, the plantar fascia acts like a windlass mechanism to provide tension and support through the arch. It functions as a tension bridge in the foot, providing both static support and dynamic shock absorption.
It is common to see patients with Plantar Fasciitis who have been wearing shoes that are too soft and flexible. The lack of support can be stressful on the heel for those patients who’s feet aren’t particularly stable. If these ill fitting shoes are worn for long enough, the stress will lead to Heel Pain as the inflammation of the fascia persists. Footwear assessment and advice will be essential in order to get on top of the Plantar Fasciitis. It may surprise some people to learn that high heeled shoes are not the cause of Plantar Fasciitis, although they can cause tight calf muscles. High arches can lead to Plantar Fasciitis. This is due to the lack of contact under the sole of the foot. Even sports shoes which appear to have good arch support inside are often too soft and not high enough to make contact with the arch of the foot. Hence, the plantar fascia is unsupported. This can lead to Heel pain and Plantar Fasciitis. Flat feet can lead to Plantar Fasciitis. Flat feet is caused by ligament laxity and leads to foot instability. Other structures such as muscles, tendons and fascia work harder to compensate for this instability. Heel pain or Plantar Fasciitis arises when the instability is too great for these other structures to cope with. The strain on the fascia is too severe and the inflammation sets in. Over stretching can lead to Plantar Fasciitis. Certain calf stretches put the foot into a position that creates a pulling sensation through the sole of the foot. This can cause Plantar Fasciitis which can cause pain in the arch of the foot as well as Heel Pain.
Plantar fasciitis has a few possible symptoms. The symptoms can occur suddenly or gradually. Not all of the symptoms must be present at once. The classic symptom of plantar fasciitis is pain around the heel with the first few steps out of bed or after resting for a considerable period of time. This pain fades away a few minutes after the feet warm up. This symptom is so common that it symbols the plantar fasciitis disorder. If you have it then probably you have plantar fasciitis. If you don’t suffer from morning pain then you might want to reconsider your diagnosis. Pain below the heel bone at the connection of the bone to the fascia. As the condition becomes more severe the pain can get more intense during the day without rest. Plantar fasciitis symptoms include pain while touching the inside of the heel or along the arch. Foot pain after you spend long periods of time standing on your feet. Pain when stretching the plantar fascia. Foot pain that worsens when climbing stairs or standing on the toes. Pain that feels as though you are walking on glass. Pain when you start to exercise that gets better as you warm up but returns after you stop.
Physical examination is the best way to determine if you have plantar fasciitis. Your doctor examines the affected area to determine if plantar fasciitis is the cause of your pain. The doctor may also examine you while you are sitting, standing, and walking. It is important to discuss your daily routine with your doctor. An occupation in which you stand for long periods of time may cause plantar fasciitis. An X-ray may reveal a heel spur. The actual heel spur is not painful. The presence of a heel spur suggests that the plantar fascia has been pulled and stretched excessively for a long period of time, sometimes months or years. If you have plantar fasciitis, you may or may not have a heel spur. Even if your plantar fasciitis becomes less bothersome, the heel spur will remain.
Non Surgical Treatment
Management options are usually conservative. Local injection of steroids, local anaesthetic may be useful to manage symptoms. Ultrasound-guided steroid injection has been shown to be effective in short-term (four-week) pain relief and reduced thickness of the plantar fascia at three months. A posterior tibial nerve block can be performed prior for a less painful plantar fascia injection. Specific plantar fascia stretching exercises performed daily have been shown to reduce short-term (8 weeks) and long-term (two years) pain. Other supportive measures include weight reduction in obese patients, rest, non-steroidal anti-inflammatory drugs (NSAIDs) and reduction of weight-bearing pressure (soft rubber heel pad, molded orthosis, or heel cup or soft-soled shoes).
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.
