Developmental dysplasia of the hip (DDH) was one of the most common hip disorders disease in children. Pemberton osteotomy (PO) was one of the most widely used by the pediatric orthopedic surgeons. In our clinical work, the investigators found some defect the operation procedure. When the surgeons were not familiar to the PO, it may injured the triradiate cartilage or easily be absorbable of the distal iliac. Here, the investigators found a new pelvic osteotomy just from the inner "L shaped" iliac osteotomy (ILSO) to treat DDH. This approach was in a visible part of the sciatic notch and not presumed to be in the ischium, completely out of sight. Comparing to the PO method, the investigators' operation method was easy to master and had less complications.
