The plantar fascia is a band of connective tissue that runs along the sole from the heel to the ball of the foot. One of its main roles is to keep the bones and joints in position. Bruising or overstretching this ligament can cause inflammation and heel pain. A common cause is flat feet, because the ligament is forced to overstretch as the foot spreads out and the arch flattens. The pain may be worse first thing in the morning or after rest. In many cases, plantar fasciitis is associated with heel spur. The plantar fascia tears and bleeds at the heel and, over time, these injuries calcify and form a bony growth.
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 foot’s 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.
The most common symptoms of plantar fasciitis include pain on the bottom of the foot near the heel, pain with the first few steps after getting out of bed in the morning, or after a long period of rest, such as after a long car ride. The pain subsides after a few minutes of walking. Greater pain after (not during) exercise or activity.
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
Careful attention to footwear is critical. Every effort should be made to wear comfortable shoes with proper arch support, fostering proper foot posture. Should arch supports prove insufficient, an orthotic shoe should be considered. Fortunately, most cases of plantar fasciitis respond well to non-operative treatment. Recovery times however vary enormously from one athlete to another, depending on age, overall health and physical condition as well as severity of injury. A broad period between 6 weeks and 6 months is usually sufficient for proper healing. Additionally, the mode of treatment must be flexible depending on the details of a particular athlete’s injury. Methods that prove successful in one patient, may not improve the injury in another. Early treatment typically includes the use of anti-inflammatory medication, icing, stretching activities, and heel inserts and splints. Cortisone injections may be necessary to achieve satisfactory healing and retard inflammation. In later stages of the rehabilitation process, typically after the first week, ice should be discontinued and replaced with heat and massage.
Most studies indicate that 95% of those afflicted with plantar fasciitis are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don’t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. While the success rate is very high following surgery, one should be aware that there is often a prolonged postoperative period of discomfort similar to the discomfort experienced prior to surgery. This pain usually will abate within 2-3 months. One should always be sure to understand all the risks associated with any surgery they are considering.
In one exercise, you lean forward against a wall with one knee straight and heel on the ground. Your other knee is bent. Your heel cord and foot arch stretch as you lean. Hold for 10 seconds, relax and straighten up. Repeat 20 times for each sore heel. It is important to keep the knee fully extended on the side being stretched. In another exercise, you lean forward onto a countertop, spreading your feet apart with one foot in front of the other. Flex your knees and squat down, keeping your heels on the ground as long as possible. Your heel cords and foot arches will stretch as the heels come up in the stretch. Hold for 10 seconds, relax and straighten up. Repeat 20 times. About 90 percent of people with plantar fasciitis improve significantly after two months of initial treatment. You may be advised to use shoes with shock-absorbing soles or fitted with an off-the-shelf shoe insert device like a rubber heel pad. Your foot may be taped into a specific position. If your plantar fasciitis continues after a few months of conservative treatment, your doctor may inject your heel with steroidal anti-inflammatory medication. If you still have symptoms, you may need to wear a walking cast for two to three weeks or a positional splint when you sleep. In a few cases, surgery is needed for chronically contracted tissue.
