Acetabular Deficiency

Chapter

Abstract

Acetabular deficiency may result from a number of causes the more common being congenital, post-traumatic or post arthroplasty loosening. The existing classifications are mainly associated with a previously placed acetabular cup since post-traumatic deficiency and congenital deficiencies are usually covered by other classifications (eg classifications for acetabular fractures or congenital femoral deficiency classifications which include acetabular participation descriptions). The Paprosky acetabular defect classification system, which was proposed in 1994, includes assessments made both by using radiologic findings and at surgery. This system attempts to stratify the degree of host bone loss in order to estimate the ability to achieve stable cementless fixation for any given bone loss pattern.
