The plantar fascia (a connective tissue structure) stretches from the toes and ball of the foot, through the arch, and connects to the heel bone in three places: outside, center and inside. Normally it helps the foot spring as it rolls forward. It also provides support for the arch of the foot. The plantar fascia helps keep the foot on track, cutting down on oscillation. When the foot over-pronates (rolls to the inside) the plantar fascia tries to stabilize it and prevent excessive roll. In time, the inside and sometimes center connections are overstressed and pull away from their attachments. The first sign is usually heel pain as you rise in the morning. When you walk around, the pain may subside, only to return the next morning. Inflammation and increased soreness are the results of long-term neglect and continued abuse. A heel bone spur may develop after a long period of injury when there is no support for the heel. The plantar fascia attaches to the heel bone with small fibers. When these become irritated they become inflamed with blood containing white blood cells. Within the white blood cells are osteoblasts which calcify to form bone spurs and calcium deposits. The body is trying to reduce stress on that area by building a bone in the direction of stress. Unfortunately, these foreign substances cause pain and further irritation in the surrounding soft tissue.
Inappropriate footwear is the No. 1 cause of plantar fasciosis. Footwear that possesses toe spring and a tapered toe box holds your big toe in an adducted and extended position. In this position, your abductor hallucis muscle-the muscle responsible for moving your big toe away from your footâs midline-pulls on a foot structure called the flexor retinaculum and may restrict blood flow through your posterior tibial artery, the vessel that carries blood to the bottom of your foot. Tissues in the sole of your feet begin to degenerate as blood supply to this area is decreased. Other recognized causes of or contributors to this health problem include the following, calf muscle shortening, plantar fascia contracture, Obesity, rheumatoid arthritis, reactive arthritis, Psoriatic arthritis, Corticosteroid injections.
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.
To diagnose plantar fasciitis, your doctor will physically examine your foot by testing your reflexes, balance, coordination, muscle strength, and muscle tone. Your doctor may also advise a magnetic resonance imaging (MRI) or X-ray to rule out other others sources of your pain, such as a pinched nerve, stress fracture, or bone spur.
Non Surgical Treatment
The good news is that plantar fasciitis is reversible and very successfully treated. About 90 percent of people with plantar fasciitis improve significantly within two months of initial treatment. If your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medications (corticosteroid). Cortisone injections have been shown to have short-term benefits but they actually retard your progress in the medium to long-term, which usually means that you will suffer recurrent bouts for longer. Due to poor foot biomechanics being the primary cause of your plantar fasciitis it is vital to thoroughly assess and correct your foot and leg biomechanics to prevent future plantar fasciitis episodes or the development of a heel spur. Your physiotherapist is an expert in foot assessment and its dynamic biomechanical correction. They may recommend that you seek the advice of a podiatrist, who is an expert in the prescription on passive foot devices such as orthotics.
The majority of patients, about 90%, will respond to appropriate non-operative treatment measures over a period of 3-6 months. Surgery is a treatment option for patients with persistent symptoms, but is NOT recommended unless a patient has failed a minimum of 6-9 months of appropriate non-operative treatment. There are a number of reasons why surgery is not immediately entertained including. Non-operative treatment when performed appropriately has a high rate of success. Recovery from any foot surgery often takes longer than patients expect. Complications following this type of surgery can and DO occur! The surgery often does not fully address the underlying reason why the condition occurred therefore the surgery may not be completely effective. Prior to surgical intervention, it is important that the treating physician ensure that the correct diagnosis has been made. This seems self-evident, but there are other potential causes of heel pain. Surgical intervention may include extracorporeal shock wave therapy or endoscopic or open partial plantar fasciectomy.
Stretching exercises for your foot are important. Do the stretches shown here at least twice a day. Don't bounce when you stretch. Plantar fascia stretch. To do the plantar fascia stretch, stand straight with your hands against a wall and your injured leg slightly behind your other leg. Keeping your heels flat on the floor, slowly bend both knees. You should feel the stretch in the lower part of your leg. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. Calf stretch. Stand with your hands against a wall and your injured leg behind your other leg. With your injured leg straight, your heel flat on the floor and your foot pointed straight ahead, lean slowly forward, bending the other leg. You should feel the stretch in the middle of your calf. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. Other exercises. You can also strengthen your leg muscles by standing on the ball of your foot at the edge of a step and raising up as high as possible on your toes. Relax between toe raises and let your heel fall a little lower than the edge of the step. It's also helpful to strengthen the foot by grabbing a towel with your toes as if you are going to pick up the towel with your foot. Repeat this exercise several times a day.
