This retrospective study evaluated the results of two procedures in two groups of patients. The Catterall classification was adopted for grouping of patients before treatment. The Herring classification was used for comparison of the follow-up radiographs. Under the concept of surgical containment, triple innominate osteotomy was performed in 14 patients at an average age of 8 years 7 months with a mean follow-up period of 4 years 3 months. Staheli's shelf augmentation was performed in 14 patients at an average age of 10 years 2 months with a follow-up period of 3 years 8 months. Radiologically, femoral head subluxation, acetabular coverage, acetabular angle, and center-edge angle were significantly improved in both groups . In the clinical evaluation using modified Sundt's criteria , both procedures were effective. Satisfactory results could be achieved in 79 % of 14 patient (5 good, 6 fair and 3 poor) in the triple osteotomy group, and 100 % of 14 patient (2 good, 12 fair) in the shelf augmentation group. Nevertheless, triple innominate osteotomy is more technically demanding with longer operative time and higher complications. Staheli's shelf augmentation is a simpler procedure with better coverage of the acetabulum. However, asphericity of the femoral heads was observed more frequently in this group. The Herring 's lateral pillar classification was better than the Catterall classification in the predicting the final outcomes in this study.en-USPerthes diseasetriple innominate osteotomyacetabular augmentation
