Legs that are not the same length may be caused by pelvic tilt, scoliosis, etc. Conservative or surgical treatments are available. 1. Pelvic tilt: If the pelvic tilt caused by bad lifestyle habits leads to legs not being the same length, conservative treatment will firstly correct the sitting and sleeping postures, such as keeping the head up and keeping the chest in sitting position, and adopting the flat position when sleeping as much as possible, so as to improve the imbalance of bilateral pelvic muscles and alleviate the pelvic tilt. If congenital hip dysplasia causes pelvic tilt, hip replacement surgery will be performed to correct the length of the lower leg. 2. Scoliosis: if the pelvis is tilted due to scoliosis, and the degree of scoliosis is within the range of 20~40 degrees, the scoliosis can be treated conservatively by wearing suitable corrective braces according to the bending condition; if the degree of scoliosis is more than 40 degrees, and the conservative treatment does not rectify the symptom that the legs are not the same length, then surgery is feasible to correct the scoliosis, and to improve the scoliosis, and to recover the length of the legs. If the legs are not the same length, you should consult a doctor as soon as possible and complete the examination to avoid missing the best treatment time due to scoliosis.
