The technique of reimplantation as it relates to bone defect

Bone loss is the principal problem in hip prosthesis revision surgery; repair of this loss may identify the method itself of reimplantation. In light of thirteen years of hip reimplantation surgery the authors propose a classification of bone loss that correlates pathologic anatomy with surgical strategy. Thus, three types of acetabular bone loss and four types of femoral bone loss are distinguished, to which correspond just as many surgical strategies, aimed at an attempt to obtain stability of the revision implant and its longer duration in time.
