title: En-bloc femoral cement removal after failure of cemented total hip replacement in two dogs.
abstract: In two dogs with periprosthetic infection after total hip replacement, the femoral cement mantle was retrieved by proximal extraction without an invasive osteotomy or cortical fenestration. En-bloc femoral cement removal was performed by injection of polymethylmethacrylate cement into the central mantle void left after stem removal, and by threading a positive profile pin into the newly injected cement. Once the PMMA had polymerized, the pin was withdrawn with the entire mantle attached. This technique should be considered in patients with circumferential deterioration of the femoral bone-cement interface in which the diameter of the femoral isthmus would not obstruct withdrawal of the cement mantle.
