Foot pain affects nearly all people at one time or another. It can also lead to other musculoskeletal problems such as ankle, knee and back pain (Hill et al., 2008). This pain negatively affects one’s quality of life and ability to enjoy workouts and/or maintain a regular program of exercise. One of the most common sources of foot pain is plantar fasciitis, a condition where the connective tissue on the underside of the foot becomes irritated and painful as a result of an injury, overuse or misuse. The plantar fascia is a system of connective tissue that runs from your heel to just behind your toes. During weightbearing activities, such as walking or running, your body weight is transferred onto your foot from your heel to your toes (which results in your toes moving away from your heel). This spreading out of the foot places tension on the plantar fascia because it connects those two parts. If the tension on this structure is too great or is not dispersed evenly, the plantar fascia can develop microtears and become irritated and painful, resulting in a condition called plantar fasciitis.
There are several possible causes of plantar fasciitis, including wearing high heels, gaining weight, increased walking, standing, or stair-climbing. If you wear high-heeled shoes, including western-style boots, for long periods of time, the tough, tendonlike tissue of the bottom of your foot can become shorter. This layer of tissue is called fascia. Pain occurs when you stretch fascia that has shortened. This painful stretching might happen, for example, when you walk barefoot after getting out of bed in the morning. If you gain weight, you might be more likely to have plantar fasciitis, especially if you walk a lot or stand in shoes with poor heel cushioning. Normally there is a pad of fatty tissue under your heel bone. Weight gain might break down this fat pad and cause heel pain. Runners may get plantar fasciitis when they change their workout and increase their mileage or frequency of workouts. It can also occur with a change in exercise surface or terrain, or if your shoes are worn out and don’t provide enough cushion for your heels. If the arches of your foot are abnormally high or low, you are more likely to develop plantar fasciitis than if your arches are normal.
People with this condition sometimes describe the feeling as a hot, sharp sensation in the heel. You usually notice the pain first thing in the morning when you stand. After walking for a period of time, the pain usually lessens or even disappears. However, sharp pain in the center of the heel may return after resting for a period of time and then resuming activity.
X-rays are a commonly used diagnostic imaging technique to rule out the possibility of a bone spur as a cause of your heel pain. A bone spur, if it is present in this location, is probably not the cause of your pain, but it is evidence that your plantar fascia has been exerting excessive force on your heel bone. X-ray images can also help determine if you have arthritis or whether other, more rare problems, stress fractures, bone tumors-are contributing to your heel pain.
Non Surgical Treatment
In many instances, plantar fasciitis can be treated with home care. Changing your physical activities, resting the foot, and applying ice to the area are common remedies. Taking over the counter medications such as ibuprofen or acetaminophen can help reduce pain and inflammation that may have developed. An orthotic device placed in your shoes can also significantly help to reduce pain. In addition, orthotics can also help promote healing to reverse plantar fasciitis. If pain from plantar fasciitis continues despite conservative treatments, you may need to visit a doctor or podiatrist. It’s important to seek medical advice before heel pain and damage becomes worse. If the condition is allowed to worsen, more serious or invasive forms of treatment may be required to stop pain. A visit to a doctor may reveal other conditions affecting the foot as well, such as Achilles tendonitis, heel spurs, or other heel pain conditions. An x-ray may also be taken, which can reveal the presence of a heel spur. In rare cases surgery may be required to release tension on the plantar fascia, or to remove a portion of a heel spur. But again, most heel pain conditions can be resolved using conservative treatment.
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.
