This book provides an up-to-date overview of shelf acetabuloplasty, a traditional procedure for acetabular dysplasia.

Originally, shelf acetabuloplasty was mainly intended for the treatment of developmental dysplasia of the hip (DDH) in children and adolescents. However, secondary osteoarthritis of the hip due to DDH is more common than primary osteoarthritis, and shelf acetabuloplasty was subsequently applied to such cases in adults. Recently, periacetabular pelvic osteotomies, such as the rotational acetabular osteotomy have established themselves and are broadly indicated as joint-preserving operations for secondary hip osteoarthritis. With the increased interest in pelvic osteotomies, the role of shelf acetabuloplasty as a reliable and safe procedure now needs to be redefined.

Each chapter was prepared by an expert in his or her field. The authors highlight the essence of the indication, discuss advanced and cutting-edge techniques, and assess the outcomes of shelf acetabuloplasty. Taken together, they provide a valuable contribution to hip surgery.
