Plantar fasciitis is the most common cause of heel pain. Pain from plantar fasciitis is often most noticeable during the first few steps after getting out of bed in the morning. The plantar fascia is a thick band of tissue in the sole of the foot. Microtearing at the origin of the plantar fascia on the heel bone (calcaneus) can occur with repetitive loading. This microtearing leads to an inflammatory response (healing response) which produces the pain. Risk factors for plantar fasciitis include excessive standing, increased body weight, increasing age, a change in activity level, and a stiff calf muscle. Plantar fasciitis can be managed non-operatively in the vast majority of patients. The main components of an effective non-operative treatment program are: calf stretching with the knee straight, plantar fascia stretching, activity modification (to avoid precipitating activities), and comfort shoe wear.
Plantar fasciitis is usually not the result of a single event but more commonly the result of a history of repetitive micro trauma combined with a biomechanical deficiency of the foot. Arthritic changes and metabolic factors may also playa part in this injury but are unlikely in a young athletic population. The final cause of plantar fasciitis is “training errors.” In all likelihood the injury is the result of a combination of biomechanical deficiencies and training errors. Training errors are responsible for up to 60% of all athletic injuries (Ambrosius 1992). The most frequent training error seen with plantar fasciitis is a rapid increase in volume (miles or time run) or intensity (pace and/or decreased recovery). Training on improper surfaces, a highly crowned road, excessive track work in spiked shoes, plyometrics on hard runways or steep hill running, can compromise the plantar fascia past elastic limits. A final training error seen in athletics is with a rapid return to some preconceived fitness level. Remembering what one did “last season” while forgetting the necessity of preparatory work is part of the recipe for injury. Metabolic and arthritic changes are a less likely cause of plantar fasciitis among athletes. Bilateral foot pain may indicate a metabolic or systemic problem. The definitive diagnosis in this case is done by a professional with blood tests and possibly x-rays.
The symptoms of plantar fasciitis are pain on the bottom of the heel, pain in the arch of the foot, pain that is usually worse upon arising, pain that increases over a period of months. People with plantar fasciitis often describe the pain as worse when they get up in the morning or after they’ve been sitting for long periods of time. After a few minutes of walking the pain decreases, because walking stretches the fascia. For some people the pain subsides but returns after spending long periods of time on their feet.
Plantar fasciitis is usually diagnosed by a health care provider after consideration of a person’s presenting history, risk factors, and clinical examination. Tenderness to palpation along the inner aspect of the heel bone on the sole of the foot may be elicited during the physical examination. The foot may have limited dorsiflexion due to tightness of the calf muscles or the Achilles tendon. Dorsiflexion of the foot may elicit the pain due to stretching of the plantar fascia with this motion. Diagnostic imaging studies are not usually needed to diagnose plantar fasciitis. However, in certain cases a physician may decide imaging studies (such as X-rays, diagnostic ultrasound or MRI) are warranted to rule out other serious causes of foot pain. Bilateral heel pain or heel pain in the context of a systemic illness may indicate a need for a more in-depth diagnostic investigation. Lateral view x-rays of the ankle are the recommended first-line imaging modality to assess for other causes of heel pain such as stress fractures or bone spur development. Plantar fascia aponeurosis thickening at the heel greater than 5 millimeters as demonstrated by ultrasound is consistent with a diagnosis of plantar fasciitis. An incidental finding associated with this condition is a heel spur, a small bony calcification on the calcaneus (heel bone), which can be found in up to 50% of those with plantar fasciitis. In such cases, it is the underlying plantar fasciitis that produces the heel pain, and not the spur itself. The condition is responsible for the creation of the spur though the clinical significance of heel spurs in plantar fasciitis remains unclear.
Non Surgical Treatment
Conservative treatment is almost always successful, given enough time. Traditional treatment often includes, rest, NSAIDs, and new shoes or heel inserts. Some doctors also recommend avoiding walking bare-footed. This means you’d have to wear your shoes as soon as you wake up. Certain foot and calf exercises are often prescribed to slowly build strength in the ligaments and muscles that support the arch of the foot. While traditional treatment usually relieves pain, it can last from several months to 2 years before symptoms get better. On average, non-Airrosti patients tend to get better in about 9 months.
Surgery is considered only after 12 months of aggressive nonsurgical treatment. Gastrocnemius recession. This is a surgical lengthening of the calf (gastrocnemius) muscles. Because tight calf muscles place increased stress on the plantar fascia, this procedure is useful for patients who still have difficulty flexing their feet, despite a year of calf stretches. In gastrocnemius recession, one of the two muscles that make up the calf is lengthened to increase the motion of the ankle. The procedure can be performed with a traditional, open incision or with a smaller incision and an endoscope, an instrument that contains a small camera. Your doctor will discuss the procedure that best meets your needs. Complication rates for gastrocnemius recession are low, but can include nerve damage. Plantar fascia release. If you have a normal range of ankle motion and continued heel pain, your doctor may recommend a partial release procedure. During surgery, the plantar fascia ligament is partially cut to relieve tension in the tissue. If you have a large bone spur, it will be removed, as well. Although the surgery can be performed endoscopically, it is more difficult than with an open incision. In addition, endoscopy has a higher risk of nerve damage.
