Standing straight when one leg is shorter is the equivalent of standing sideways on a hill. The person cannot help but lean to the shorter side. The spine may compensate by tilting the upper body in the opposite direction. This produces a "scoliosis" or sideways deviation of the spine. It also concentrates gravitational and kinetic stress on the area where the spine transitions to the sacrum and pelvis... the lumbo-sacral junction.... NOT GOOD. Often a person will try to compensate for a short leg by perching on short leg, usually with the longer leg bent at the knee and turned out...effectively shortening the long leg. NOT GOOD. Rather than balancing the pelvis, fatigue and strain usually causes the pelvis to over compensate. In either case, the distortion of the spine unevenly loads the joints and muscles, and promotes faster wear and tear, and injury. If you, or someone you care about, is persistently perching on one leg, or complaining of back pain, t
