title: [Anchoring principles in hip prosthesis implantation. II: Acetabulum components].
abstract: In this review the different anchorage concepts of cemented and cementless acetabular components are presented and clinical long-term results--if available--are discussed. Despite numerous design improvements and modifications the long-term durability of acetabular components remains a major concern with results being clearly inferior than achieved with femoral components. Until valid, prospective long-term success is proven for cementless designs cemented acetabular fixation using modern cementing technique must be regarded as standard treatment. However, successful fixation over 15-20 years very much depends on the quality of operative and cementing technique. Some cementless systems appear easier to use and have been documented to offer reliable mid-term survival rates. In young patients cementless devices have been well established and for some systems promising 10-year results have been published.
