Overview
Flat feet and fallen arches are common conditions that are in most cases asymptomatic. However, in patients who do have symptoms, treatments are available that can help reduce pain and promote efficient movement. Orthotic devices are well recognised as an excellent treatment and podiatrists can offer these different treatment modalities as individualised treatments for patients. Causes The direct cause of being flat footed is linked to a muscular imbalance in the intrinsic muscles of the foot and ankle. When your main arch-supporting tendon, the posterior tibial tendon, decreases in strength due to muscle decay or injury, the foot begins to flatten and can cause pain during normal activities. Weakness in the tendon can be present at birth due to genetics or can develop from early walking patterns. However, in most people who experience fallen arches, it comes from strain due to aging or placed on the feet from standing or walking in heels for long periods of time. Improper footwear that doesn?t support the arch of the foot, diabetes and obesity can increase your risk of developing fallen arches. Symptoms People will have a very heavily dropped arch and it won?t affect them at all and people will have it slightly dropped and it could cause fierce problems. It could cause things like plantar fasciitis, it could cause heel spurs, desperate ball-of-the-foot pressure, or pressure on the big toe known as the hallux which causes discomfort in the foot. It will create problems upwards to the knees, hips and the back once you?re out of line. Diagnosis If your child has flatfeet, his or her doctor will ask about any family history of flatfeet or inherited foot problems. In a person of any age, the doctor will ask about occupational and recreational activities, previous foot trauma or foot surgery and the type of shoes worn. The doctor will examine your shoes to check for signs of excessive wear. Worn shoes often provide valuable clues to gait problems and poor bone alignment. The doctor will ask you to walk barefoot to evaluate the arches of the feet, to check for out-toeing and to look for other signs of poor foot mechanics. The doctor will examine your feet for foot flexibility and range of motion and feel for any tenderness or bony abnormalities. Depending on the results of this physical examination, foot X-rays may be recommended. X-rays are always performed in a young child with rigid flatfeet and in an adult with acquired flatfeet due to trauma. What is PES Planovalgus deformity? Non Surgical Treatment If fallen arches are not causing any pain or discomfort, then they will not need any treatment. If they were causing a persistent pain in the feet, or in the hips, legs or knees, then it would be best to consult your family doctor. Walking is the natural activity of feet and if it is not too painful, sufferers should walk as much as possible to strengthen their arches. When it is possible, go barefoot, or wear soft flexible shoes. In cases of severe fallen arches, your doctor may recommend special shoe inserts. Surgical Treatment Surgical procedures for flat feet vary depending on the root cause of the condition. Surgical correction to control pronation may include bone implants or Achilles tendon lengthening. Tendon transfer, which is a procedure to re-attach a tendon to another area of bone, may also be used to reduce pronation and improve foot function. Prevention Sit up straight in a chair with your feet flat on the ground. Scrunch up the toes of one foot as if you are trying to grab hold of the floor then use your toes to drag your foot a small distance forwards. Do this a couple of times on each foot, but don?t use your leg muscles to push your foot forward -- the movement should come solely from the muscles in your feet. Sit in a chair and place a cleaning cloth, towel or small ball on the floor at your feet. Use the toes of one foot to grasp the object and lift it off the floor. This action will require you to clench your toes and contract your arch. Once you have lifted the object a little way off the floor, try to throw it in the air and catch it by stretching your toes and arch out and upwards. Repeat the exercise several times on both feet. Sit on the floor with your legs straight out in front of you then bend your knees out to either side and place the soles of your feet together so your legs form a diamond. Hold on to your ankles and, keeping your heels together at all times, separate your feet so your toes point out to either side. Open and close your feet in this way several times, making sure your little toes stay in contact with the floor throughout the exercise. Starting in the same position, try separating your heels, keeping your toes together at all times. After Care Time off work depends on the type of work as well as the surgical procedures performed. . A patient will be required to be non-weight bearing in a cast or splint and use crutches for four to twelve weeks. Usually a patient can return to work in one to two weeks if they are able to work while seated. If a person's job requires standing and walking, return to work may take several weeks. Complete recovery may take six months to a full year. Complications can occur as with all surgeries, but are minimized by strictly following your surgeon's post-operative instructions. The main complications include infection, bone that is slow to heal or does not heal, progression or reoccurrence of deformity, a stiff foot, and the need for further surgery. Many of the above complications can be avoided by only putting weight on the operative foot when allowed by your surgeon.

Overview
Leg length difference (LLD) is primarily when the hips are not level, causing a limp from side to side. Most practitioners divide LLD into anatomical or functional. Anatomical is when there is a true difference in the length of the tibia/fibula or the femur bone, or both. While functional LLD are either the shortening or lengthening of a limb, secondary to joint contracture or muscle imbalances. Causes LLDs are very common. Sometimes the cause isn?t known. But the known causes of LLD in children include, injury or infection that slows growth of one leg bone. Injury to the growth plate (a soft part of a long bone that allows the bone to grow). Growth plate injury can slow bone growth in that leg. Fracture to a leg bone that causes overgrowth of the bone as it heals. A congenital (present at birth) problem (one whole side of the child?s body may be larger than the other side). Conditions that affect muscles and nerves, such as polio. Symptoms Many people walk around with LLD?s of up to 2 cm. and not even know it. However, discrepancies above 2 cm. becomes more noticeable, and a slight limp is present. But even up to 3 cm. a small lift compensates very well, and many patients are quite happy with this arrangement. Beyond 3 cm. however, the limp is quite pronounced, and medical care is often sought at that point. Walking with a short leg gait is not only unsightly, but increases energy expenditure during ambulation. It could also put more stress on the long leg, and causes functional scoliosis. Where the discrepancy is more severe, walking becomes grotesque or virtually impossible. Diagnosis There are several orthopedic tests that are used, but they are rudimentary and have some degree of error. Even using a tape measure with specific anatomic landmarks has its errors. Most leg length differences can be seen with a well trained eye, but I always recommend what is called a scanagram, or a x-ray bone length study (see picture above). This test will give a precise measurement in millimeters of the length difference. Non Surgical Treatment People with uneven leg lengths may be more prone to pain in their back, hips, and knees; uneven gait; and lower leg and foot problems. Due to its risks, surgery is typically not recommended unless the difference is greater than one inch. In cases where the difference is less than one inch, providing the same support for both feet is the most effective. This can be achieved by getting custom-fitted orthotics for both feet. Orthotics are inserts that you wear in the shoes. Your chiropractor will request to measure your feet and possibly your legs. You can step on a device that will take the measurements or you might have a plaster cast of your feet taken. Orthotics are typically made from plastic and leather, and function biomechanically with your foot. If a leg length discrepancy is not properly corrected with orthotics, your chiropractor may recommend a heel lift, also known as a shoe lift. You simply place it in the back of your shoe along with the orthotic. Typically, you will only wear the heel lift in one shoe to assist the shorter leg. heelsncleavage Surgical Treatment Surgery to shorten the longer leg. This is less involved than lengthening the shorter leg. Shortening may be done in one of two ways. Closing the growth plate of the long leg 2-3 years before growth ends (around age 11-13), letting the short leg catch up. This procedure is called an epiphysiodesis. Taking some bone from the longer leg once growth is complete to even out leg lengths. Surgery to lengthen the shorter leg. This surgery is more involved than surgery to shorten a leg. During this surgery, cuts are made in the leg bone. An external metal frame and bar are attached to the leg bone. This frame and bar slowly pull on the leg bone, lengthening it. The frame and bar must be worn constantly for months to years. When the frame and bar are removed, a leg cast is required for several months. This surgery requires careful and continued follow-up with the surgeon to be sure that healing is going well. |
