Methods From July 1995 to July 2000, 45 children with developmental dysplasia, hip subluxation, legg pertes disease and flat hip were treated with tibial acetabulum enlargement. Introduce slotted acetabular augmentation surgery skills, to explore its indications, contraindications and the recent results. Results The tibial acetabular augmentation using crossed mesh bone grafting, easy to shape mortar, postoperative children can get a sleek, well-structured acetabular, it is suitable for stable structure, acetabular index within 40 ° of the hip Mortar dysplasia, advanced dislocation of the hip, Leggperthes disease, flat hip and other children’s treatment. Conclusions Slotted acetabular augmentation is an effective way to enlarge the acetabular area and make the hip more stable. It is in line with anatomical “shelf” type of capping surgery. The method is simple, safe and effective
