Generally speaking, according to the unanimous opinion of experts from the International Hip Society and the domestic pediatric orthopedic group, for children within 15 months of age, they can be rehabilitated by internal repositioning, manipulation and plaster fixation, and the current repositioning effect is satisfactory, but the biggest complication is ischemic necrosis of the femoral head, which requires full communication with parents before surgery. For children over 15 months of age who can already walk, incisional repositioning and Salter’s pelvic osteotomy are mostly used, and the younger the child, the better the long-term results; for children over 6 years of age, a variety of treatments are used, especially Le Core pelvic triple osteotomy, which can improve the healing of the hip joint and reduce the occurrence of late osteoarthritis to a greater extent. There are different treatment opinions for children aged 10 years or older with bilateral hip dislocation, but for unilateral children, surgical repositioning is still recommended at the age of 10-13 years. Since we started hip treatment in the 1990s, the results have been improving, and the current results are around 90% for hips up to 6 years old, with good long-term recovery.
