The symptoms include abnormal posture and gait, especially when squatting, both knees cannot come together when squatting, and both legs must be separated; when sitting, you cannot cross your legs; when lying down, both knees are separated, when standing, both lower limbs are mildly externally rotated, and both feet cannot come together completely, showing an “external figure of eight”, and walking hobbled, especially when walking fast or running. When walking, especially when walking fast or running, it is jumping, similar to the strange “Chaplin gait” on the stage. The key is that pediatricians and parents should pay great attention to this disease and minimize or avoid injecting toxic and irritating drugs into the hip muscles. 2, the injection method and site should be correct, the dosage should be reasonable, the injection speed should be slow, and continuous injection of the same site should be avoided as much as possible. After injection, apply local heat and physiotherapy appropriately to facilitate the absorption of the drug and improve local blood circulation. Once hip contracture is found, early surgery should be performed. Therefore, if you find that your child walks differently from a normal person, you should consult a doctor in time, and the earlier the treatment, the greater the possibility of healing. In recent years, due to the widespread use of arthroscopy and the maturity of the technology, it can be applied to the treatment of gluteus contracture. Its advantages are: (1) small incision, fast healing, small scars, no obvious impact on the aesthetics, but also to avoid fat liquefaction, non-healing, etc.; (2) cut off under direct vision, avoiding injury to other important tissues, to the point of where to cut (3) faster recovery after surgery, the second day you can go down, basically can normal general activities, significantly shorten the hospitalization time.
