Technique for fabrication of an antibiotic-loaded cement hemiarthroplasty (ANTILOCH) prosthesis for infected total hip arthroplasty.

Overview

In North America, staged reimplantation is the preferred treatment for infected total hip arthroplasty. A simple technique for implantation of an antibiotic-loaded cement spacer molded in the shape of a hemiarthroplasty prosthesis is described. A Teflon mold was cast in the shape of an Austin Moore hip hemiarthroplasty prosthesis. This mold allows for fabrication of a solid antibiotic-loaded cement spacer that accurately reproduces the shape of a hemiarthroplasty prosthesis. This technique allows for easy insertion, patient comfort, between-stage mobility, and local concentric delivery of antibiotic.
