Plain-English summary
Two dogs developed infections after having total hip replacements and needed surgery to remove the cement used in the procedure. Instead of a more invasive surgery, the vets used a special technique to extract the cement without cutting into the bone. They injected new cement into the area and then pulled out the old cement along with the new material. This method was successful in both dogs, allowing for the removal of the infected cement without additional complications.

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 Once the PMMA had polymerized, the pin was withdrawn with the entire mantle attached.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.
