How Can I Tell If I Have Overpronation Of The Foot
If you've been running long enough, you've most likely had to deal with various aches and pains in your feet, knees, hips or lower back. Plantar fasciitis, achilles tendinitis, IT-band syndrome, meniscus tears, runner's knee, bursitis of the hip or knee, patellofermoral pain syndrome, chondromalacia patella, lower back pain and piriformis syndrome are only some of many conditions an athlete may develop during the course of his or her running career.Causes
Over-pronation is very prominent in people who have flexible, flat feet. The
framework of the foot begins to collapse, causing the foot to flatten and adding stress to other parts of the foot. As a result, over-pronation, often leads to Plantar Fasciitis, Heel Spurs, Metatarsalgia, Post-tib Tendonitis and/or Bunions. The
re are many causes of flat feet. Obesity, pregnancy or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Of
ten people with flat feet do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.Symptoms
If ignored, overpronation can lead to complications such as hammer toes, corns and calluses, shin splints, hallux rigidus and many more foot and lower leg problems. Hammer toes appear when the toes are placed under too much pressure and the ligaments and muscles in the toes begin to reduce in size, leading to the curvature of the toes and making them look like little hammers. Overpronators can develop hammertoes if they don?t wear an appropriate pair of shoes. Corns and calluses also appear as a result of overpronation. The
y form in response to excess pressure, and overpronators may find that they have excessive hard skin on the balls of the feet and inside edge of the big toe. It is the body?s way of protecting against excessive forces and friction. The
y can be painful.Diagnosis
If you have flat feet or low arches, chances are you overpronate. Although not always the case, the lower your arches the greater the overpronate. Stand on a hard surface (in front of a mirror if you need to) and look at your feet, flat feet or low arches are easy to spot. If your feet look flatter than a pancake, have a look at your ankles and see if they seem collapsed or straight. If they are, you're overpronating.Non Surgical Treatment
Flat feet and fallen arches can be treated effectively by wearing an orthotic insert in your shoes. Orthotics can be custom-made and prescribed by your foot specialist (podiatrist), or you can use a so called pre-made foot orthotic. Most people do not require expensive custom-made orthotics to combat excess pronation, unless they have a specific medical foot condition. Foot
logics orthotic insoles were developed to correct excess pronation, thereby providing sustainable, long-lasting pain relief to many aches and pains in a natural way. Foot
logics Comfort, Casual and Sports are products which promote excellent biomechanical control of the foot.Surgical Treatment
Subtalar Arthroereisis. The
ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
Calcaneal Apophysitis The Facts
Sever's disease is an overuse syndrome involving an immature part of the skeleton. Pain goes away when the overuse is over, or when the growing is done. Hence, the disease is self-limited, in that the pain goes away eventually when growth in the heel bone is complete at about age 13. Even if the child is hurting, as long as he can tolerate it, he may continue to take part in sports. No long term disability is expected from this problem.
Predisposing Hereditary Factors: These are a biomechanical defect that one may be born with, which increases the chances of developing Sever's Disease. Short Achilles Tendon, When the Achilles Tendon is short from birth, it will exaggerate the tightness of this tendon that occurs during a child's growing years. This makes the pull of the Achilles Tendon on the heel's growth plate more forceful than normal, causing inflammation and pain, and eventually Sever's Disease. Short Leg Syndrome, When one leg is shorter than the other, the foot on the short leg must plantar flex (the foot and toes bend down) in order to reach the ground. In this way, the body tries to equalize the length of the legs. In order for the foot to plantar flex, the Achilles Tendon must pull on the heel with greater force than if the leg was a normal length. Thus the heel on the short leg will be more susceptible to Sever's Disease during the foot's growing years. Pronation. Is a biomechanical defect of the foot that involves a rolling outward of the foot at the ankle, so that when walking, the inner side of the heel and foot bears more of the body's weight than is normal (click here for more information about pronation). Pronation thus causes the heel to be tilted or twisted. In order for the Achilles Tendon to attach to the heel, it must twist to reach its normal attachment site. This will shorten or tighten the Achilles Tendon and increase the force of its pull on the heel's growth plate. This will increase the tightness of the Achilles Tendon during the foot's growing years, and may help to initiate bouts of Sever's Disease. Flat Arches and High Arches. Both of these biomechanical foot defects effect the pitch, or angle of the heel within the foot. When the heel is not positioned normally within the foot due to the height of the arch, the Achilles Tendon's attachment to the heel is affected. This may produce a shortening or tightening of the Achilles Tendon, which increases the force of its pull on the heel's growth plate. During the foot's growing years, abnormal arch height may contribute to the onset of Sever's Disease.
Chief complaint is heel pain which increases pain during running and jumping activities. Pain is localized to the very posterior aspect of the heel. Pain is elicited only with weightbearing. Mild involvement is present if pain is brought on only with running during sports. The symptoms can be severe, with pain (and possibly limp) with activities of daily living (ie walking).
Physical examination varies depending on the severity and length of involvement. Bilateral involvement is present in approximately 60% of cases. Most patients experience pain with deep palpation at the Achilles insertion and pain when performing active toe raises. Forced dorsiflexion of the ankle also proves uncomfortable and is relieved with passive equinus positioning. Swelling may be present but usually is mild. In long-standing cases, the child may have calcaneal enlargement.
Non Surgical Treatment
Your podiatrist can help manage this condition by implementing a treatment program. This may incorporate one or all of the following. RI (Rest and Ice). Activity modification so child becomes pain free. Daily stretching routine. Heel raise within shoes to decrease pull on heel. Biomechanical abnormalities corrected (Orthotics). Strengthening of associated muscles. Footwear modification.
In some cases, children will simply outgrow Sever's Disease when they reach a certain age, but this does not mean that symptoms should be ignored. If children express that they are in pain, this should always be taken seriously by their parents or guardians. Heel pain may be a sign of Sever's Disease and this condition should not be left untreated, due to the damage it can cause to the growing heel bones. Scheduling a doctor's appointment is always the first step to take in gaining a diagnosis of symptoms and speedy help for the child.
Leg Length Discrepancy Chiropractic Treatment
Epiphysiodesis is a surgical option designed to slow down the growth of the long leg over a period of months to years. It is only used in growing children. The operation involves a general anaesthetic. Small incisions are made around the knee near the growth plates of the thigh bone and the shin bone. The growth plates are prevented from growing by the use of small screws and plates (?8 - plates?). The screws are buried beneath the skin and are not visible. Stitches are buried beneath the skin and do not need to be removed. The child is normally in hospital for 2-3 days. The child can weight bear immediately and return back to normal activity within a few weeks. Long term follow up is required to monitor the effects of the surgery. The timing of the surgery is based on the amount of growth predicted for the child. Therefore, this procedure can under- and over-correct the difference in leg length. Occasionally the screws have to be removed to allow growth to continue. This procedure can be used on one half of the growth plate to correct deformity in a limb e.g. knock-knees or bow legs. This is known as hemiepiphysiodesis.Causes
A number of causes may lead to leg length discrepancy in children. Differences in leg length frequently follow fractures in the lower extremities in children due to over or under stimulation of the growth plates in the broken leg. Leg
length discrepancy may also be caused by a congenital abnormality associated with a condition called hemihypertrophy. Or it may result from neuromuscular diseases such as polio and cerebral palsy. Many times, no cause can be identified. A small leg length discrepancy of a quarter of an inch or less is quite common in the general population and of no clinical significance. Larger leg length discrepancies become more significant. The long-term consequences of a short leg may include knee pain, back pain, and abnormal gait or limp.Symptoms
The effects vary from patient to patient, depending on the cause of the discrepancy and the magnitude of the difference. Differences of 3 1/2 to 4 percent of the total length of the lower extremity (4 cm or 1 2/3 inches in an average adult), including the thigh, lower leg and foot, may cause noticeable abnormalities while walking and require more effort to walk. Differences between the lengths of the upper extremities cause few problems unless the difference is so great that it becomes difficult to hold objects or perform chores with both hands. You and your physician can decide what is right for you after discussing the causes, treatment options and risks and benefits of limb lengthening, including no treatment at all. Although an LLD may be detected on a screening examination for curvature of the spine (scoliosis), LLD does not cause scoliosis. There is controversy about the effect of LLD on the spine. Some studies indicate that people with an LLD have a greater incidence of low back pain and an increased susceptibility to injuries, but other studies refute this relationship.Diagnosis
Asymmetry is a clue that a LLD is present. The center of gravity will shift to the short limb side and patients will try to compensate, displaying indications such as pelvic tilt, lumbar scoliosis, knee flexion, or unilateral foot pronation. Asking simple questions such as, "Do you favor one leg over the other?" or, "Do you find it uncomfortable to stand?" may also provide some valuable information. Performing a gait analysis will yield some clues as to how the patient compensates during ambulation. Using plantar pressure plates can indicate load pressure differences between the feet. It is helpful if the gait analysis can be video-recorded and played back in slow motion to catch the subtle aspects of movement.Non Surgical Treatment
Treatment of leg length inequality involves many different approaches, such as orthotics, epiphysiodesis, shortening, and lengthening, which can be used alone or combined in an effort to achieve equalization of leg lengths. Leg
length inequality of 2 cm or less is usually not a functional problem. Often, leg length can be equalized with a shoe lift, which usually corrects about two thirds of the leg length inequality. Up to 1 cm can be inserted in the shoe. For larger leg length inequalities, the shoe must be built up. This needs to be done for every shoe worn, thus limiting the type of shoe that the patient can wear. Leg
length inequalities beyond 5 cm are difficult to treat with a shoe lift. The shoe looks unsightly, and often the patient complains of instability with such a large lift. A foot-in-foot prosthesis can be used for larger leg length inequalities. This is often done as a temporizing measure for young children with significant leg length inequalities. The prosthesis is bulky, and a fixed equinus contracture may result.Surgical Treatment

Posterior Tibial Tendon Pain Symptoms
Acquired adult flatfoot deformity (AAFD) is a progressive flattening of the arch of the foot that occurs as the posterior tibial tendon becomes insufficient. It has many other names such posterior tibial tendon dysfunction, posterior tibial tendon insufficiency and dorsolateral peritalar subluxation. This problem may progress from early stages with pain along the posterior tibial tendon to advanced deformity and arthritis throughout the hindfoot and ankle.Causes
There are multiple factors contributing to the development of this problem. Damage to the nerves, ligaments, and/or tendons of the foot can cause subluxation (partial dislocation) of the subtalar or talonavicular joints. Bone fracture is a possible cause. The resulting joint deformity from any of these problems can lead to adult-acquired flatfoot deformity. Dysfunction of the posterior tibial tendon has always been linked with adult-acquired flatfoot deformity (AAFD). The loss of active and passive pull of the tendon alters the normal biomechanics of the foot and ankle. The reasons for this can be many and varied as well. Diabetes, high blood pressure, and prolonged use of steroids are some of the more common causes of adult-acquired flatfoot deformity (AAFD) brought on by impairment of the posterior tibialis tendon. Overstretching or rupture of the tendon results in tendon and muscle imbalance in the foot leading to adult-acquired flatfoot deformity (AAFD). Rheumatoid arthritis is one of the more common causes. About half of all adults with this type of arthritis will develop adult flatfoot deformity over time. In such cases, the condition is gradual and progressive. Obesity has been linked with this condition. Loss of blood supply for any reason in the area of the posterior tibialis tendon is another factor. Other possible causes include bone fracture or dislocation, a torn or stretched tendon, or a neurologic condition causing weakness.Symptoms
The symptoms of PTTD may include pain, swelling, a flattening of the arch, and an inward rolling of the ankle. As the condition progresses, the symptoms will change. For example, when PTTD initially develops, there is pain on the inside of the foot and ankle (along the course of the tendon). In addition, the area may be red, warm, and swollen. Later, as the arch begins to flatten, there may still be pain on the inside of the foot and ankle. But at this point, the foot and toes begin to turn outward and the ankle rolls inward. As PTTD becomes more advanced, the arch flattens even more and the pain often shifts to the outside of the foot, below the ankle. The tendon has deteriorated considerably and arthritis often develops in the foot. In more severe cases, arthritis may also develop in the ankle.Diagnosis
Observation by a skilled foot clinician and a hands-on evaluation of the foot and ankle is the most accurate diagnostic technique. Your Dallas foot doctor may have you do a walking examination (the most reliable way to check for the deformity). During walking, the affected foot appears more pronated and deformed. Your podiatrist may do muscle testing to look for strength deficiencies. During a single foot raise test, the foot doctor will ask you to rise up on the tip of your toes while keeping your unaffected foot off the ground. If your posterior tendon has been attenuated or ruptured, you will be unable to lift your heel off the floor. In less severe cases, it is possible to rise onto your toes, but your heel will not invert normally. X-rays are not always helpful as a diagnostic tool for Adult Flatfoot because both feet will generally demonstrate a deformity. MRI (magnetic resonance imaging) may show tendon injury and inflammation, but can?t always be relied on for a complete diagnosis. In most cases, a MRI is not necessary to diagnose a posterior tibial tendon injury. An ultrasound may also be used to confirm the deformity, but is usually not required for an initial diagnosis.Non surgical Treatment
Options range from shoe inserts, orthotics, bracing and physical therapy for elderly and/or inactive patients to reconstructive surgical procedures in those wishing to remain more active. These treatments restore proper function and alignment of the foot by replacing the damaged muscle tendon unit with an undamaged, available and expendable one, lengthening the contracted Achilles tendon and realigning the Os Calcis, or heel bone, while preserving the joints of the hindfoot. If this condition is not recognized before it reaches advanced stages, a fusion of the hindfoot or even the ankle is necessary. Typically this is necessary in elderly individuals with advanced cases that cannot be improved with bracing.Surgical Treatment
Surgical correction is dependent on the severity of symptoms and the stage of deformity. The goals of surgery are to create a more functional and stable foot. There are multiple procedures available to the surgeon and it may take several to correct a flatfoot deformity. Usually surgical treatment begins with removal of inflammatory tissue and repair of the posterior tibial tendon. A tendon transfer is performed if the posterior tibial muscle is weak or the tendon is badly damaged. The most commonly used tendon is the flexor digitorum longus tendon. This tendon flexes or moves the lesser toes downward. The flexor digitorum longus tendon is utilized due to its close proximity to the posterior tibial tendon and because there are minimal side effects with its loss. The remainder of the tendon is sutured to the flexor hallucis longus tendon that flexes the big toe so that little function is loss.
