Besides infection persistence and or reinfection major complications after hip spacer implantation include spacer fracture -dislocation and bone fracture. Moreover in cases with extensive loss of femoral and or acetabular bone alternative reconstructive techniques should be used for a stable spacer fixation and prevention of fractures or dislocations. The present article reviews the different types of spacer fractures and dislocations and offers some suggestions about reconstructive techniques for management of extensive loss of femoral and or acetabular bone at the site of hip spacer implantation. Key words hip spacers spacer fracture spacer dislocation femoral fracture reconstruction. Introduction Over the past two decades antibiotic-impregnated hip spacers have become a popular procedure in the treatment of hip joint infections with reported success rates of 90 1 . Although initially developed for the management of infected total hip arthroplasties hip spacers have been successfully used also in the .
