The plantar fascia is a thick, ligamentous connective tissue that runs from the heel bone to the ball of the foot. This strong and tight tissue helps maintain the arch of the foot. It is also one of the major transmitters of weight across the foot as you walk or run. Thus, tremendous stress is placed on the plantar fascia, often leading to plantar fasciitis- a stabbing or burning pain in the heel or arch of the foot. Plantar fasciitis is particularly common in runners. People who are overweight, women who are pregnant and those who wear shoes with inadequate support are also at a higher risk. Prolonged plantar fasciitis frequently leads to heel spurs, a hook of bone that can form on the heel bone. The heel spur itself is not thought to be the primary cause of pain, rather inflammation and irritation of the plantar fascia is the primary problem.
The cause of plantar fasciitis is poorly understood and is thought to likely have several contributing factors. The plantar fascia is a thick fibrous band of connective tissue that originates from the medial tubercle and anterior aspect of the heel bone. From there, the fascia extends along the sole of the foot before inserting at the base of the toes, and supports the arch of the foot. Originally, plantar fasciitis was believed to be an inflammatory condition of the plantar fascia. However, within the last decade, studies have observed microscopic anatomical changes indicating that plantar fasciitis is actually due to a non-inflammatory structural breakdown of the plantar fascia rather than an inflammatory process. Due to this shift in thought about the underlying mechanisms in plantar fasciitis, many in the academic community have stated the condition should be renamed plantar fasciosis. The structural breakdown of the plantar fascia is believed to be the result of repetitive microtrauma (small tears). Microscopic examination of the plantar fascia often shows myxomatous degeneration, connective tissue calcium deposits, and disorganized collagen fibers. Disruptions in the plantar fascia’s normal mechanical movement during standing and walking (known as the Windlass mechanism) are thought to contribute to the development of plantar fasciitis by placing excess strain on the calcaneal tuberosity.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as arthritis , or a nerve problem such as tarsal tunnel syndrome.
Diagnosis of plantar fasciitis is based on a medical history, the nature of symptoms, and the presence of localised tenderness in the heel. X-rays may be recommended to rule out other causes for the symptoms, such as bone fracture and to check for evidence of heel spurs. Blood tests may also be recommended.
Non Surgical Treatment
Most health care providers agree that initial treatment for plantar fasciitis should be quite conservative. You’ll probably be advised to avoid any exercise that is making your pain worse. Your doctor may also advise one or more of these treatment options. A heel pad. In plantar fasciitis, a heel pad is sometimes used to cushion the painful heel if you spend a great deal of time on your feet on hard surfaces. Also, over-the-counter or custom-made orthotics, which fit inside your shoes, may be constructed to address specific imbalances you may have with foot placement or gait. Stretching: Stretching exercises performed three to five times a day can help elongate the heel cord. Ice: You may be advised to apply ice packs to your heel or to use an ice block to massage the plantar fascia before going to bed each night. Pain relievers: Simple over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, are often helpful in decreasing inflammation and pain. If you have stomach trouble from such drugs, your health care provider may prescribe an alternative. A night splint: A night splint is sometimes used to hold your foot at a specific angle, which prevents the plantar fascia from shortening during sleep. Ultrasound: Ultrasound therapy can be performed to decrease inflammation and aid healing. Steroid injections: Anti-inflammatory steroid injections directly into the tissue around your heel may be temporarily helpful. However, if these injections are used too many times, you may suffer other complications, such as shrinking of the fat pad of your heel, which you need for insulation. Loss of the fat pad could actually increase your pain, or could even rupture the plantar fascia in rare cases. Walking cast: In cases of long-term plantar fasciitis unresponsive to usual treatments, your doctor may recommend that you wear a short walking cast for about three weeks. This ensures that your foot is held in a position that allows the plantar fascia to heal in a stretched, rather than shortened, position. Shock wave therapy, Extracorporeal shock wave therapy which may be prescribed prior to considering surgery if your symptoms have persisted for more than six months. This treatment does not involve any actual incisions being made rather it uses a high intensity shock wave to stimulate healing of the plantar fascia.
Surgery is rarely used in the treatment of plantar fasciitis. However it may be recommended when conservative treatment has been tried for several months but does not bring adequate relief of symptoms. Surgery usually involves the partial release of the plantar fascia from the heel bone. In approximately 75% of cases symptoms are fully resolved within six months. In a small percentage of cases, symptoms may take up to 12 months to fully resolve.
While it’s typical to experience pain in just one foot, massage and stretch both feet. Do it first thing in the morning, and three times during the day. Achilles Tendon Stretch. Stand with your affected foot behind your healthy one. Point the toes of the back foot toward the heel of the front foot, and lean into a wall. Bend the front knee and keep the back knee straight, heel firmly planted on the floor. Hold for a count of 10. Plantar Fascia Stretch. Sit down, and place the affected foot across your knee. Using the hand on your affected side, pull your toes back toward your shin until you feel a stretch in your arch. Run your thumb along your foot–you should feel tension. Hold for a count of 10.
