Can one have a shorter leg due to muscle spasm in the back, while the SI Joint is in the correct place?
You could have some tightness in your quadratus. Lie on your back, have your chiro gently swing your left leg over your right while holding your left shoulder down and stretch your left flank. Now put your leg flat and check your leg length. Now have him reach between your legs with his left hand and grasp your ischial tuberosity and buttock and place his right hand with his thumb along side of the index finger on the back part of the iliac crest. Now pull up with his left hand and rotate the back of the pelvis down and in with his right hand. Check the leg length and that leg will probably be even more short than it was before. This is what should happen! Now rotate the right side back in the same manner and that side will get shorter. Do again on each side until no more shortening occurs. In no case should he pull down on the short leg in the long axis in line with the body or have you side-lying and pull your left shoulder back and shove your left hip down in front.
