Iliac osteotomy is a commonly used surgical treatment method in developmental hip dysplasia. Iliac osteotomies are classified as complete or incomplete. Pemberton and Dega osteotomies are among the most commonly applied incomplete iliac osteotomies. Both medial and lateral cortex of the iliac bone at the supraacetabular region were cut down back to the triaradiate cartilage at Pemberton osteotomy and rotation center is triradiate cartilage. Only lateral cortex of iliac bone is cut down to static notch and osteotome is directed medially to the triradiate cartilage at Dega osteotomy and rotation center is again triradiate cartilage.

In this review, indications, surgical technique and clinical results of Pemberton and Dega iliac osteotomies were discussed.
