So is it normal to have a leg length difference? I always though my left leg was noticable longer until I started going to a chiropractor regularly. Now they're the same length. WHen one seems longer again, a trip to the chiro fixes it.
I am a keeper of useless information. I have troves and troves of one day obsessions. I have few things that keep me interested longer than a few days or weeks. U2 is one of them. I've been obsessed with U2 since I was 16 and saw Zoo TV.
Hip dysplasias or back problems can simulate a leg length difference.
Pretty much nobody has a perfect symmetrical body, so some leg length difference is fairly common. Most of the time, it is almost unnoticable. It gets obvious when the difference approaches 3/4 of an inch to 1 inch.
The greatest LLD I've seen was somewhere around 10-12 inches. I saw it with my own eyes, but I still haven't quite grasped how somebody can walk that asymmetrically and not fall over.
There are generally two kinds of leg length discrepancies.
* Structural discrepancy occurs when either the thigh (femur) or shin (tibia) bone in one leg is actually shorter than the corresponding bone in the other leg as a result of a condition that has either caused one bone to be shorter than normal or longer than normal.
* Functional discrepancy occurs when the leg lengths are equal, by symmetry is altered somewhere above the leg, which in turn disrupts the symmetry of the legs. For example, developmental dislocation of the hip can cause a functional discrepancy. In DDH, the top of the leg bone (femur) that is not properly positioned in the hip socket may hang lower than the femur on the other side, giving the appearance and symptoms of a leg length discrepancy.
