Leg length discrepancies are differences between the lengths of your legs. Not only can the actual difference vary from person to person but also how much it affects daily life. Small discrepancies often go unnoticed and do not need to be treated. Larger differences may affect posture or cause a limp during walking. The discrepancy may be from the upper leg bone (femur) or the lower leg bone (tibia).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
The most common symptom of all forms of LLD is chronic backache. In structural LLD the sufferer may also experience arthritis within the knee and hip are, flank pain, plantar fasciitis and metatarsalgia all on the side that is longer. Functional LLD sufferers will see similar conditions on the shorter side.Diagnosis
On standing examination one iliac crest may be higher/lower than the other. However a physiotherapist, osteopath or chiropractor will examine the LLD in prone or supine position and measure it, confirming the diagnosis of structural (or functional) LLD. The LLD should be measured using bony fixed points. X-Ray should be taken in a standing position. The osteopath, physiotherapist or chiropractor will look at femoral head & acetabulum, knee joints, ankle joints.Non Surgical Treatment
A personalized approach to leg length discrepancy treatment works best for each patient. Your child's doctor will consider many factors when deciding on a course of treatment for this condition. Such factors can include your child's age, extent of the leg length discrepancy, medical history, how your child tolerates certain treatments and procedures, your child's health and prognosis, growth rate, and parental preferences. There is no cookie cutter treatment for each child, or even each centimeter of leg difference. Once all of these factors have been carefully considered, your child's physician will come up with an appropriate course of care. In situations of a very small leg length discrepancy, no treatment, only periodic medical evaluation, may be necessary.how we can increase our height?Surgical Treatment
Surgery is another option. In some cases the longer extremity can be shortened, but a major shortening may weaken the muscles of the extremity. In growing children, lower extremities can also be equalized by a surgical procedure that stops the growth at one or two sites of the longer extremity, while leaving the remaining growth undisturbed. Your physician can tell you how much equalization can be attained by surgically halting one or more growth centers. The procedure is performed under X-ray control through very small incisions in the knee area. This procedure will not cause an immediate correction in length. Instead, the LLD will gradually decrease as the opposite extremity continues to grow and "catch up." Timing of the procedure is critical; the goal is to attain equal length of the extremities at skeletal maturity, usually in the mid- to late teens. Disadvantages of this option include the possibility of slight over-correction or under-correction of the LLD and the patient?s adult height will be less than if the shorter extremity had been lengthened. Correction of significant LLDs by this method may make a patient?s body look slightly disproportionate because of the shorter legs.
