Screw augmented cement spacer for deficient acetabulum in periprosthetic infection following Total Hip Arthroplasty.

For periprosthetic joint infection (PJI) treatment, revision total hip arthroplasty using an antibiotic loaded cement spacer is one of the important surgical methods. However, revision total hip arthroplasty using antibiotic-loaded cement spacers poses a risk of spacer dislodgement in patients with acetabular deficiency. We hypothesized that screw augmentation would be more stable and result in lower rates of cement spacer dislodgement in acetabular deficient patients. Thus, we suggest a method of screw augmentation with cement spacers to treat periprosthetic infection in patients with a deficient acetabulum. And we aim to report better clinical outcomes after revision total hip arthroplasty for infection control using screw augmented cement spacer insertion technique. Level of evidence: IV.
