To improve the slotted acetabular augmentation to treat acetabular dysplasia. Fifteen pediatric patients with developmental dysplasia of the hip, 3 male and 12 female, aged 8 - 16, with 20 ill acetabuli, underwent improved slotted acetabular augmentation: a piece of cancellous bone was grafted into a groove of the acetabulum, and the volume of acetabulum was enlarged. The effects were evaluated by clinical examination, X-ray examination, Charnley scoring, and Harris scoring. After the operation, the acetabular covering rate became 85%, and the mean acetabular index was decreased from 35 degrees to 25 degrees. Slotted acetabular augmentation is safe, simple, and effective in the treatment of acetabular dysplasia.
