Figure 3: Left: Procedural change. Internal posterior stabilization Th11/12 – L2/3 (Longitude/Medtronic; 6.5 mm pedicle screws). The antibiotic chains were left in situ. Because of the good bone quality, a pedicle screw augmentation was not necessary. Right: Removal of the antibiotic chains after further 4 weeks. Due to a progressive osseous bridging, there was no need for an anterior stabilization.
