What if a 15 year old walks with one shoulder high and one shoulder low?

Depending on the cause, a 15-year-old child walking with a high shoulder can be treated conservatively or surgically.
Walking with high and low shoulders may be caused by walking habits, scoliosis deformity, unequal length of legs, hip dysplasia and so on. Generally, the diagnosis can be made by X-ray, CT or MRI with specialized examination in regular hospitals, and different treatments can be adopted according to different causes.
Shoulder inequality caused by walking habit and scoliosis deformity can be treated conservatively, mainly by correcting walking posture and orthopedic treatment with brace, observing whether the deformity progresses or not during the treatment, and reviewing once a month, if the treatment is ineffective, and the scoliosis progresses to be more than 40°~50°, surgery should be chosen.
Walking with unequal shoulders caused by unequal legs, hip dysplasia or scoliosis greater than 40~50° should be treated surgically. Surgery is mainly to correct the unequal length of the lower limbs, hip structure and scoliosis, and to treat the appearance of walking with unequal shoulders fundamentally.
It is recommended to go to the regular hospital to improve the relevant examination, to clarify the cause of the disease, and if necessary, to actively treat the disease to avoid the progress of the disease.
