The Limitation of Endoscopic Surgery Using the Full Endoscopic Discectomy System for the Treatment of Destructive Stage Pyogenic Spondylodiscitis: A Case Series

Figure 2

A 75-year-old male with L4/L5 pyogenic spondylitis underwent endoscopic debridement. Because low back pain did not improve postoperatively, anterior reconstruction surgery with an iliac autograft was performed. (a) Preoperative sagittal CT scans revealed destructive endplate at the L4/L5 level. (b) Post-endoscopic surgery sagittal CT scans showing further bone destruction. (c) Post-open surgery sagittal CT scan view showing the bony fusion without severe kyphotic deformity.(d, e) Intraoperative view and iliac autograft; minimally invasive surgery was performed via the direct lateral retroperitoneal approach, and the large defect due to debridement was reconstructed with the strut bone collected from the ilium.
