Overview

Heel pain is a very common foot problem. The sufferer usually feels pain either under the heel (planter fasciitis) or just behind it (Achilles tendinitis), where the Achilles tendon connects to the heel bone. Even though Heel Pain can be severe and sometimes disabling, it is rarely a health threat. Heel pain is typically mild and usually disappears on its own, however, in some cases the pain may persist and become chronic (long-term). There are 26 bones in the human foot, of which the heel (calcaneus) is the largest. The human heel is designed to provide a rigid support for the weight of the body. When we are walking or running it absorbs the impact of the foot when it hits the ground, and springs us forward into our next stride. Experts say that the stress placed on a foot when walking may be 1.25 times our body weight, and 2.75 times when running. Consequently, the heel is vulnerable to damage, and ultimately pain.

Causes

Age plays a large role in the development of heel pain, particularly among those over 40. Being active is also a common factor of heel pain. Over time, the elasticity of the tissue in our feet decreases with age, causing us to become prone to damage and also slowing the body’s ability to heal damage. Adolescents are also not immune to heel pain. Those who are active in sports are particularly prone to excessively stretching or straining the plantar fascia or Achilles tendon, causing severe heel pain. In most cases, heel pain develops in only one heel. There are many risk factors that lead to heel pain. Abnormal gait and excessive, repetitive stress are common factors in the development of pain and damage. Among the other risk factors involved with the development of heel pain are repetitive exercise or activities, such as long distance running or jumping from activities such as basketball. Obesity. Walking barefoot on hard surfaces. Prolonged standing. Wearing poor fitting shoes, or shoes that do not provide enough support or cushioning. Not stretching properly or at all before and after exercise. Those who are on their feet for long periods of time.

Symptoms

Both heel pain and heel spurs are frequently associated with an inflammation of the long band of tissue that connects the heel and the ball of the foot. The inflammation of this arch area is called plantar fasciitis. The inflammation maybe aggravated by shoes that lack appropriate support and by the chronic irritation that sometimes accompanies an athletic lifestyle. Achilles Tendinopathy, Pain and inflammation of the tendon at the back of the heel that connects the calf muscle to the foot. Sever?s, Often found in children between the ages of 8 – 13 years and is an inflammation of the calcaneal epiphyseal plate (growth plate) in the back of the heel. Bursitis, An inflamed bursa is a small irritated sack of fluid at the back of the heel. Other types of heel pain include soft tissue growths, Haglunds deformity (bone enlargement at the back of the heel), bruises or stress fractures and possible nerve entrapment.

Diagnosis

The diagnosis of heel pain and heel spurs is made by a through history of the course of the condition and by physical exam. Weight bearing x-rays are useful in determining if a heel spur is present and to rule out rare causes of heel pain such as a stress fracture of the heel bone, the presence of bone tumors or evidence of soft tissue damage caused by certain connective tissue disorders.

Non Surgical Treatment

If the plantar fasciitis is acute, that is, a sprain of the plantar fascia then it is basically treated as a sprain, with anti-inflammatory drugs, ice, rest, possibly physical therapy. If chronic, the poor foot mechanics need be addressed. Foot mechanics are changed by use of specially moulded shoe inserts known as orthotics. Someone with plantar fasciitis needs an orthotic designed to relieve strain on the plantar fascia. Orthotics are often confused with arch supports. Arch supports, by holding up the arch can remove some of the tension from the plantar fascia. Orthotics, on the other hand, do most of their work on the heel and ball of the foot repositioning the foot for maximized function. What can you do before you see the foot doctor? First, try doing your own version of deep tissue massage by rolling a frozen cola bottle or can from the heel forward into the arch. Do it gently. Do stretching but the key to good stretching is not to stretch too hard so generally avoid weight bearing (standing) stretches but sit on a soft surface like your bed and pull the foot backward on the leg as far as it will go, holding for 20 seconds and relaxing for 5 seconds. Each 25 second ?set? can be repeated 5 times and you have invested about 2 minutes in giving yourself a lot of help. Watch out for the shoes you wear. It is tempting to obtain shoes that are colorful and soft. Here is the proof that soft shoes are bad. Wrap a pillow around your foot with duct tape and walk for a block or two. You will come back with your foot hurting more because your foot sank down deeper into the soft surface, allowing the ligament to stretch more. The shoes should be stiff in the shank and flexible at the ball. Such shoes, to running buffs, are known as motion control shoes or stability shoes so going to one of the small specialty running shoes stores is a good place to start. If you don?t have a desk job, or have an industrial job see if light duty is available. A note from your doc may be all that is required in most cases and most doctors are happy to oblige.

Surgical Treatment

Surgery is a last resort in the treatment of heel pain. Physicians have developed many procedures in the last 100 years to try to cure heel pain. Most procedures that are commonly used today focus on several areas, remove the bone spur (if one is present), release the plantar fascia (plantar fasciotomy), release pressure on the small nerves in the area. Usually the procedure is done through a small incision on the inside edge of the foot, although some surgeons now perform this type of surgery using an endoscope. An endoscope is a tiny TV camera that can be inserted into a joint or under the skin to allow the surgeon to see the structures involved in the surgery. By using the endoscope, a surgeon can complete the surgery with a smaller incision and presumably less damage to normal tissues. It is unclear whether an endoscopic procedure for this condition is better than the traditional small incision. Surgery usually involves identifying the area where the plantar fascia attaches to the heel and releasing the fascia partially from the bone. If a small spur is present this is removed. The small nerves that travel under the plantar fascia are identified and released from anything that seems to be causing pressure on the nerves. This surgery can usually be done on an outpatient basis. This means you can leave the hospital the same day.

Prevention

It may not be possible to prevent all cases of heel pain. However, there are some easy steps that you can take to avoid injury to the heel and prevent pain. Whenever possible, you should wear shoes that fit properly and support the foot, wear the right shoes for physical activity, stretch your muscles before exercising, pace yourself during physical activity, maintain a healthy diet, rest when you feel tired or when your muscles ache, maintain a healthy weight.

Overview

The adult acquired flatfoot (AAF) is a progressive, symptomatic (painful) deformity resulting from gradual stretch (attenuation) of the tibialis posterior tendon as well as the ligaments that support the arch of the foot. Although the posterior tibialis tendon plays a significant role, this pathology has recently been recognized as involving failure of other interosseous ligaments, such as the spring ligament. Due to the complexity of this pathology, posterior tibial tendon dysfunction (PTTD) is now referred to as adult acquired flatfoot. Severe flatfoot associated with AAF can lead to other problems, such as plantar fascial tension, tendon pain, rearfoot subluxation, and ankle osteoarthritis

Causes

Causes of an adult acquired flatfoot may include Neuropathic foot (Charcot foot) secondary to Diabetes mellitus, Leprosy, Profound peripheral neuritis of any cause. Degenerative changes in the ankle, talonavicular or tarsometatarsal joints, or both, secondary to Inflammatory arthropathy, Osteoarthropathy, Fractures, Acquired flatfoot resulting from loss of the supporting structures of the medial longitudinal arch. Dysfunction of the tibialis posterior tendon Tear of the spring (calcaneoanvicular) ligament (rare). Tibialis anterior rupture (rare). Painful flatfoot can have other causes, such as tarsal coalition, but as such a patient will not present with a change in the shape of the foot these are not included here.

Symptoms

The symptom most often associated with AAF is PTTD, but it is important to see this only as a single step along a broader continuum. The most important function of the PT tendon is to work in synergy with the peroneus longus to stabilize the midtarsal joint (MTJ). When the PT muscle contracts and acts concentrically, it inverts the foot, thereby raising the medial arch. When stretched under tension, acting eccentrically, its function can be seen as a pronation retarder. The integrity of the PT tendon and muscle is crucial to the proper function of the foot, but it is far from the lone actor in maintaining the arch. There is a vital codependence on a host of other muscles and ligaments that when disrupted leads to an almost predictable loss in foot architecture and subsequent pathology.

Diagnosis

First, both feet should be examined with the patient standing and the entire lower extremity visible. The foot should be inspected from above as well as from behind the patient, as valgus angulation of the hindfoot is best appreciated when the foot is viewed from behind. Johnson described the so-called more-toes sign: with more advanced deformity and abduction of the forefoot, more of the lateral toes become visible when the foot is viewed from behind. The single-limb heel-rise test is an excellent determinant of the function of the posterior tibial tendon. The patient is asked to attempt to rise onto the ball of one foot while the other foot is suspended off the floor. Under normal circumstances, the posterior tibial muscle, which inverts and stabilizes the hindfoot, is activated as the patient begins to rise onto the forefoot. The gastrocnemius-soleus muscle group then elevates the calcaneus, and the heel-rise is accomplished. With dysfunction of the posterior tibial tendon, however, inversion of the heel is weak, and either the heel remains in valgus or the patient is unable to rise onto the forefoot. If the patient can do a single-limb heel-rise, the limb may be stressed further by asking the patient to perform this maneuver repetitively.

Non surgical Treatment

Treatment depends very much upon a patient?s symptoms, functional goals, degree and specifics of deformity, and the presence of arthritis. Some patients get better without surgery. Rest and immobilization, orthotics, braces and physical therapy all may be appropriate. With early-stage disease that involves pain along the tendon, immobilization with a boot for a period of time can relieve stress on the tendon and reduce the inflammation and pain. Once these symptoms have resolved, patients are often transitioned into an orthotic that supports the inside aspect of the hindfoot. For patients with more significant deformity, a larger ankle brace may be necessary.

Surgical Treatment

Surgery is usually performed when non-surgical measures have failed. The goal of surgery is to eliminate pain, stop progression of the deformity and improve a patient?s mobility. More than one technique may be used, and surgery tends to include one or more of the following. The tendon is reconstructed or replaced using another tendon in the foot or ankle The name of the technique depends on the tendon used. Flexor digitorum longus (FDL) transfer. Flexor hallucis longus (FHL) transfer. Tibialis anterior transfer (Cobb procedure). Calcaneal osteotomy – the heel bone may be shifted to bring your heel back under your leg and the position fixed with a screw. Lengthening of the Achilles tendon if it is particularly tight. Repair one of the ligaments under your foot. If you smoke, your surgeon may refuse to operate unless you can refrain from smoking before and during the healing phase of your procedure. Research has proven that smoking delays bone healing significantly.

Overview

Achilles Tendonitis or achilles tendinopathy which is probably a more accurate term is an overuse injury causing pain, inflammation and or degeneration of the thick achilles tendon at the back of the ankle. The term achilles tendinopathy is probably a better term to describe the range of conditions that can cause achilles tendon pain. Achilles tendonitis can be either acute or chronic. Acute achilles tendonitis is usually more painful and of recent onset. Chronic achilles tendonitis will have come on gradually and over weeks, not necessarily preventing activity.

Causes

Poorly conditioned athletes are at the highest risk for developing Achilles tendonitis, also sometimes called Achilles tendinitis. Participating in activities that involve sudden stops and starts and repetitive jumping (e.g., basketball, tennis, dancing) increases the risk for the condition. It often develops following sudden changes in activity level, training on poor surfaces, or wearing inappropriate footwear. Achilles tendonitis may be caused by a single incident of overstressing the tendon, or it may result from a series of stresses that produce small tears over time (overuse). Patients who develop arthritis in the heel have an increased risk for developing Achilles tendonitis. This occurs more often in people who middle aged and older. The condition also may develop in people who exercise infrequently and in those who are just beginning an exercise program, because inactive muscles and tendons have little flexibility because of inactivity. It is important for people who are just starting to exercise to stretch properly, start slowly, and increase gradually. In some cases, a congenital (i.e., present at birth) condition causes Achilles tendonitis. Typically, this is due to abnormal rotation of the foot and leg (pronation), which causes the arch of the foot to flatten and the leg to twist more than normal.

Symptoms

Gradual onset of pain and stiffness over the tendon, which may improve with heat or walking and worsen with strenuous activity. Tenderness of the tendon on palpation. There may also be crepitus and swelling. Pain on active movement of the ankle joint. Ultrasound or MRI may be necessary to differentiate tendonitis from a partial tendon rupture.

Diagnosis

If Achilles tendonitis is suspected, avoid any exercise or activity that causes the pain. It is advisable to see a doctor promptly so that an accurate diagnosis can be made and appropriate treatment recommended. The doctor will take a full medical history and will ask about the nature and duration of the symptoms. They will perform a physical examination of the affected area. Ultrasound scanning may be used to assess damage to the tendon or surrounding structures. Occasionally MRI (magnetic resonance imaging) may be recommended. The symptoms of Achilles tendonitis are often similar to symptoms of other conditions such as partial Achilles tendon rupture and heel bursitis. This can make diagnosis difficult and a referral to an orthopaedic specialist may be required in order for an accurate diagnosis to be made.

Nonsurgical Treatment

In order to treat achilles tendinitis effectively, it is important to complete a thorough examination of the entire lower extremity. Once the true cause is identified, a comprehensive treatment program can be initiated to reduce inflammation and improve any faulty lower extremity biomechanics. Treatment options may include biomechanical analysis of gait. Splinting/bracing to alleviate the strain on the tendon. Soft tissue mobilization/manual therapy to decrease inflammation and promote healing of the tendon. Strengthening/flexibility and proprioceptive exercises. Home exercise program. Modalities for pain and inflammation (i.e. ultrasound, iontophoresis, electrical stimulation, ice). Methods to alter faulty mechanics (i.e taping, orthotics). Education about lifestyle changes (i.e. proper shoes, activity modification).

Surgical Treatment

If several months of more-conservative treatments don’t work or if the tendon has torn, your doctor may suggest surgery to repair your Achilles tendon.

Prevention

Appropriately warm up and stretch before practice or competition. Allow time for adequate rest and recovery between practices and competition. Maintain appropriate conditioning, Ankle and leg flexibility, Muscle strength and endurance, Cardiovascular fitness. Use proper technique. To help prevent recurrence, taping, protective strapping, or an adhesive bandage may be recommended for several weeks after healing is complete.
