ABSTRACT=<sec id="ST1"><title>Background</title><p>Pelvic fixation with S2-alar-iliac (S2AI) screws can increase the rigidity of a lumbosacral construct, which may promote bone healing, improve antibiotic delivery to infected tissues, and avoid L5–S1 pseudarthrosis.</p></sec><sec id="ST2"><title>Purpose</title><p>To describe the use of single-stage posterior fixation without debridement for the treatment of pyogenic vertebral diskitis and osteomyelitis (PVDO) at the lumbosacral junction.</p></sec><sec id="ST3"><title>Study design</title><p>Technical report.</p></sec><sec id="ST4"><title>Methods</title><p>We describe the management of PVDO at the lumbosacral junction in which the infection invaded the endplates, disk space, vertebrae, prevertebral soft tissues, and epidural space. Pedicle involvement precluded screw fixation at L5. Surgical management consisted of a single-stage posterior operation with rigid lumbopelvic fixation augmented with S2-alar-iliac screws and without formal debridement of the infected area, followed by long-term antibiotic treatment.</p></sec><sec id="ST5"><title>Results</title><p>At 2-year follow-up, successful fusion and eradication of the infection were achieved.</p></sec><sec id="ST6"><title>Conclusion</title><p>PVDO at the lumbosacral junction may be treated successfully using rigid posterior-only fixation without formal debridement combined with antibiotic therapy.</p></sec>
