Seventeen patients from 2007 to 2009 underwent anterior debridement and fusion with a minimally invasive approach combined with posterior fixation via the Wiltse approach. Postoperative follow-up time was 24-41 months. Data included the patients＇ general information, mi- crobiology, operative time, intraoperative blood loss, postoperative complications, intervertebral fusion rate, and preoperative and final follow-up scores for American Spinal Injury Association （ASIA） im- pairment, visual analogue scale （VAS）, and Oswestry Disability Index （ODI）. Ten patients had under- gone a prior spinal invasive procedure, and 7 had hematogenous infection. The infected segments in- cluded L1-2, L2-3, L3,~, and L4-5 in 1, 2, 5, and 9 cases, respectively. Thirteen bacterial cultures were posi- tive for Staphylococcus aureus （5 cases）, Staphylococcus epidermidis （4）, Streptococcus （3）, and Es- cherichia coli （1）. The operative time was 213.8＋45.6 min, and the intraoperative blood loss was 180.6-4-88.1 mL. Postoperative complications consisted of urinary retention （2 cases）, constipation （3）, and deep vein thrombosis （2）. On the final follow-up, VAS scores and ODIs were significantly lower than those of preoperation, while the ASIA grades improved. All the cases achieved good intervertebral bony fusion. Anterior debridement and fusion with a minimally invasive approach combined with poste- rior fixation via the Wiltse approach can successfully treat single-level lumbar pyogenic spondy- lodiscitis, with less trauma and reliable immobilization. It is a viable option for clinical application.展开更多
