  • Title: Acetabular distraction: an alternative for severe acetabular bone loss and chronic pelvic discontinuity.
    Author: Sheth NP, Melnic CM, Paprosky WG.
    Journal: Bone Joint J; 2014 Nov; 96-B(11 Supple A):36-42. PubMed ID: 25381406.
    Abstract:
    Acetabular bone loss is a challenging problem facing the revision total hip replacement surgeon. Reconstruction of the acetabulum depends on the presence of anterosuperior and posteroinferior pelvic column support for component fixation and stability. The Paprosky classification is most commonly used when determining the location and degree of acetabular bone loss. Augments serve the function of either providing primary construct stability or supplementary fixation. When a pelvic discontinuity is encountered we advocate the use of an acetabular distraction technique with a jumbo cup and modular porous metal acetabular augments for the treatment of severe acetabular bone loss and associated chronic pelvic discontinuity.
