This condition affects almost 90% of the population with an average difference of 5 mm between the length of the legs. A leg may be anatomically shorter or longer if physically a change has occurred to the physical structure. The reason for functional equality is the other one that is not caused by a structural change. \n<\/p>\n\n

Leg length inequality was classified according to the extent expressed in cm or mm and described as mild, moderate, or severe. \n<\/p>\n\n

  1. Mild minus 3 mm<\/li>
  2. Moderate 3-6 mm<\/li>
  3. Severe plus 6 mm<\/li><\/ol>\n

    In 1994, the American Academy of Orthopaedic Surgeons published a study in which it was discovered that a divergence of 1.2 cm affected the orientation of the scoliosis curve.<\/p><\/p>\n\n

    A leg length discrepancy of about 1.27 cm could lead to compensatory scoliosis of the lumbar spine. \n<\/p>\n\n

    Consequence<\/h1>\n\n

    A longer leg will try to compensate for the height of a shorter one. \n<\/p>\n\n

    This malposition will have serious long-term repercussions on the biomechanics of the lower limbs. Accelerated wear of the joints will lead to premature ambulatory difficulties. \n<\/p>\n\n

    Correction<\/h1>\n\n

    The heel cup will be beneficial in balancing the inequality.<\/p>\n\n

    \"\"<\/figure>\n

    One study indicates that an 80% reduction in pain will be experienced if a 1mm correction is made using a heel cup. \n<\/p>\n\n
