Plantar fasciitis is a common foot disorder that affects more than two million people every year, especially runners. It is inflammation of the plantar fascia, a thick band of tissue on the bottom of the foot. The most common area of pain is directly on the bottom of the heel, although some people may only have pain in the arch of the foot. Diagnosis of plantar fasciitis is typically done through a physical examination, which includes listening to the patient history, palpation of the heel and possibly x-rays.
Currently no single factor has been reliably identified as contributing to the development of plantar fasciitis. The two risk factors with the most support from current research. Decreased ankle dorsiflexion. Increased Body Mass Index (BMI) in non-athletic populations. These factors are related in that both lead to increased strain on the arch, both lead to increased compression on the heel. When dorsiflexion range of motion (ankle flexibility) is lacking, the body compensates by increasing movement of the arch. In this way, decreased ankle dorsiflexion influences pronation and places strain on the underside of the foot. Similarly, having a high BMI causes strain because it places a load on the foot that may be in excess of what the foot can support. As mentioned earlier, overpronation is thought to be a contributing factor, but studies on this have so far produced mixed results. The second way these factors relate to each other is in the way people stand. A lack of ankle flexibility and a high BMI can both cause increased pressure on the heel in standing. Keeping weight on the heels causes compression under the heel. But it also means the muscles and ligaments in the arch are not being used to balance your body weight. Lack of use, I suspect, is a greater danger than overuse. Looking beyond these potential contributors to heel pain though, there is one major factor that overshadows them all-the way footwear alters the normal function of the foot.
The most obvious symptom of plantar fasciitis is a sharp pain on the bottom of the foot, near the heel. Here are some signals that this pain may be plantar fasciitis. The pain is strongest first thing in the morning but gets better after a few minutes of walking around. The pain is worse after standing for a long time or after getting up from sitting. The pain develops gradually and becomes worse over time. The pain is worse after exercise or activity than it is during activity. It hurts when stretching the foot. It hurts when pressing on the sides of the heel or arch of the foot.
To arrive at a diagnosis, the foot and ankle surgeon will obtain your medical history and examine your foot. Throughout this process the surgeon rules out all the possible causes for your heel pain other than plantar fasciitis. In addition, diagnostic imaging studies such as x-rays or other imaging modalities may be used to distinguish the different types of heel pain. Sometimes heel spurs are found in patients with plantar fasciitis, but these are rarely a source of pain. When they are present, the condition may be diagnosed as plantar fasciitis/heel spur syndrome.
Non Surgical Treatment
Treatment for heel pain usually involves using a combination of techniques, such as stretches and painkillers, to relieve pain and speed up recovery. Most cases of heel pain get better within 12 months. Surgery may be recommended as a last resort if your symptoms don’t improve after this time. Only 1 in 20 people with heel pain will need surgery. Whenever possible, rest the affected foot by not walking long distances and standing for long periods. However, you should regularly stretch your feet and calves using exercises such as those described below. Pain relief. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, can be used to help relieve pain. Some people also find applying an ice pack to the affected heel for 5-10 minutes can help relieve pain and inflammation. However, do not apply an ice pack directly to your skin. Instead, wrap it in a towel. If you do not have an ice pack, you can use a packet of frozen vegetables.
Surgery may be considered in very difficult cases. Surgery is usually only advised if your pain has not eased after 12 months despite other treatments. The operation involves separating your plantar fascia from where it connects to the bone; this is called a plantar fascia release. It may also involve removal of a spur on the calcaneum if one is present. Surgery is not always successful. It can cause complications in some people so it should be considered as a last resort. Complications may include infection, increased pain, injury to nearby nerves, or rupture of the plantar fascia.
Stretching exercises for the Achilles tendon and plantar fascia are recommend to relieve pain and aid in the healing process. Sometimes application of athletic tape is recommended. In moderate or severe cases of plantar fasciitis, your doctor may recommend you wearing a night splint, which will stretch the arch of your foot and calf while you sleep. This helps to lengthen the Achilles tendon and plantar fascia for symptom relief. Depending on the severity of your plantar fasciitis, your physician may prescribe a store-bought orthotic (arch support) or custom-fitted orthotic to help distribute your foot pressure more evenly.
