A flat foot is a term used to described a collapsed arch. Medically, the term is pes planovalgus (for foot flatten and pushed outwards). There are varying degrees of ?flatness?. Though not all flat feet are problematic, however, when there are painful flat feet can cause significant discomfort and activity limitations. There are two kinds of flat feet - flexible (mobile) or rigid (stiff). A flexible flat foot is one where the foot retains motion, and the arch is able to be recreated when there is no weight on the foot. In contrast, a rigid flat foot is ?stuck? in the flat position regardless of whether or not there is pressure placed on the foot.
Often, tarsal tunnel syndrome is misdiagnosed and confused with plantar fasciitis. Tarsal tunnel syndrome is when the tibial nerve which runs through the ankle, is pinched as it passes through the flexor retinaculum, the supportive band that surrounds the ankle joint. The symptoms of tarsal tunnel syndrome are often limited to the ankle but the since the nerve passes through the entire foot it can cause arch pain. Arch pain associated with foot strain is mainly caused by a pronated foot (rolls inward) or a flat foot. These are usually not singular causes of arch pain, but in combination with other factors, arch pain may result.
Flat feet don't usually cause problems, but they can put a strain on your muscles and ligaments (ligaments link two bones together at a joint). This may cause pain in your legs when you walk. If you have flat feet, you may experience pain in any of the following areas, the inside of your ankle, the arch of your foot, the outer side of your foot, the calf, the knee, hip or back, Some people with flat feet find that their weight is distributed unevenly, particularly if their foot rolls inwards too much (overpronates). If your foot overpronates, your shoes are likely to wear out quickly. Overpronation can also damage your ankle joint and Achilles tendon (the large tendon at the back of your ankle). See your GP if you or your child has flat feet and your feet are painful, even when wearing supportive, well-fitting shoes, shoes wear out very quickly, feet appear to be getting flatter, feet are weak, numb or stiff, Your GP may refer you to a podiatrist (foot specialist).
A patient is asked to step with full body weight on the symptomatic foot, keeping the unaffected foot off the ground. The patient is then instructed to "raise up on the tip toes" of the affected foot. If the posterior tibial tendon has been attenuated or ruptured, the patient will be unable to lift the heel off the floor and rise onto the toes. In less severe cases, the patient will be able to rise on the toes, but the heel will not be noted to invert as it normally does when we rise onto the toes. X-rays can be helpful but are not diagnostic of the adult acquired flatfoot. Both feet, the symptomatic and asymptomatic - will demonstrate a flatfoot deformity on x-ray. Careful observation may show a greater severity of deformity on the affected side.
Non Surgical Treatment
In mild cases of flatfoot the first line of treatment is often custom orthotics. In patients with a flexible deformity, supporting the arch with a custom arch support will take the strain off the joints and muscles, bringing the heel into a corrected position. Wider shoe gear may be prescribed to accommodate foot pain and motion and stretching exercises to decrease stiffness and stress on the foot. In cases of severe collapse, especially if the patient is not a good surgical candidate or has a mild tear, a brace may be made to accommodate the foot and ankle, thus supporting the arch and ankle.
The procedure involves cutting and shifting the bone, and then performing a tendon transfer. First, the surgeon performs a calcaneal osteotomy, cutting the heel bone and shifting it into the correct position. Second, the surgeon transfers the tendon. Reroute the flexor digitorum to replace the troublesome posterior tibial tendon. Finally, the surgeon typically performs one or more fine-tuning procedures that address the patient?s specific foot deformity. Often, the surgeon will lengthen the Achilles tendon because it is common for the mispositioned foot to cause the Achilles to tighten. Occasionally, to increase the arch, the surgeon performs another osteotomy of one of the bones of the midfoot. Occasionally, to point the foot in a straightforward direction, the surgeon performs another osteotomy of the outside portion of the calcaneus.
Below are two simple plantar fasciitis stretching exercises to help improve the flexibility of the muscles and tendons around the foot and ankle. Plantar fasciitis stretch taken from The Stretching Handbook. Kneel on one foot and place your body weight over your knee. Keep your heel on the ground and lean forward. In the photo to the left, the athlete is stretching the arch of her left foot. Kneel on one foot with your hands on the ground. Place your body weight over your knee and slowly move your knee forward. Keep your toes on the ground and arch your foot. In the photo to the right, the athlete is stretching the arch of his right foot.
The Achilles tendon is the large cord like structure on the back of the leg just above the heel. It is the largest tendon in the body and has a tremendous amount of force transmitted through it during walking, running and jumping activities. The Achilles tendon is prone to injury, including rupture during periods of increased stress and activity. Common activities causing injury include running, basketball, baseball, football, soccer, volleyball and tennis. These activities require jumping and pushing forces that are possible due to the strength of the calf musculature and the ability of the Achilles tendon to endure this stress. Men from the ages of 30-50 are the most commonly injured during weekend athletic activities.
Your Achilles tendon helps you point your foot downward, rise on your toes and push off your foot as you walk. You rely on it virtually every time you move your foot. Rupture usually occurs in the section of the tendon located within 2.5 inches (6 centimeters) of the point where it attaches to the heel bone. This section may be predisposed to rupture because it gets less blood flow, which may impair its ability to heal. Ruptures often are caused by a sudden increase in the amount of stress on your Achilles tendon. Common examples include increasing the intensity of sports participation, falling from a height, stepping into a hole.
Patients often describe a feeling of being kicked or hit with a baseball bat in the back of the heel during athletic activity. They are unable to continue the activity and have an extreme loss of strength with the inability to effectively walk. On physical examination there is often a defect that can be felt in the tendon just above the heel. A diagnosis of an Achilles tendon rupture is commonly made on physical exam. An MRI may be ordered to confirm the suspicion of a tear or to determine the extent of the tear.
In order to diagnose Achilles tendon rupture a doctor or physiotherapist will give a full examination of the area and sometimes an X ray is performed in order to confirm the diagnosis. A doctor may also recommend an MRI or CT scan is used to rule out any further injury or complications.
Non Surgical Treatment
Pain medicines can help decrease pain and swelling. A cast may be needed for 2 months or more. Your foot will be positioned in the cast with your toes pointing slightly down. Your caregiver will change your cast and your foot position several times while the tendon heals. Do not move or put weight on your foot until your caregiver tells you it is okay. A leg brace or splint may be needed to help keep your foot from moving while your tendon heals. Heel lifts are wedges put into your shoe or cast. Heel lifts help decrease pressure and keep your foot in the best position for your tendon to heal. Surgery may be needed if other treatments do not work. The edges of your tendon may need to be stitched back together. You may need a graft to patch the tear. A graft is a piece of another tendon or artificial material.
A completely ruptured Achilles tendon requires surgery and up to 12 weeks in a cast. Partial tears are sometimes are treated with surgery following by a cast. Because the tendon shortens as it heals, a heel lift is used for 6 months or more after the cast comes off. Physical therapy to regain flexibility and then strength are begun as soon as the cast is off.
To help reduce your chance of getting Achilles tendon rupture, take the following steps. Do warm-up exercises before an activity and cool down exercises after an activity. Wear proper footwear. Maintain a healthy weight. Rest if you feel pain during an activity. Change your routine. Switch between high-impact activities and low-impact activities. Strengthen your calf muscle with exercises.
