Application of Intraoperative CT-Guided Navigation in Simultaneous Minimally Invasive Anterior and Posterior Surgery for Infectious Spondylitis

Figure 2

L1-L2 infectious spondylitis accompanied with epidural abscess treated with simultaneous minimally invasive anterior and posterior surgery using the iCT-guided navigation. Preoperative MRI demonstrated L1-L2 vertebral osteomyelitis and epidural abscess with obvious canal compromise (a, b). Intraoperative CT image obtained following simultaneous anterior and posterior spinal surgery (c, d) showing the spinal decompression and reconstruction. Partial resection of the L2 vertebra with reconstruction of L1-L2 with a percutaneous pedicle screw-rod construct and interbody iliac strut bone grafting (e, f).
