Developmental Dysplasia of the Hip

Brief summary

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.

Interventions

PROCEDUREa new osteotomy from the inner L shaped iliac osteotomy

There were two ostectomies were used in the osteotomy. The first was was a cured and 5mm width and the second one was straight 1.5cm width. All the directions was started from the inner to outer just a bove the triradiate cartilage and its shape likeL
