AbstractDebridement is warranted for the treatment of nontuberculous spondylodiscitis in case of neurological compromise, deformity, instability, abscess formation, extensive destruction, intractable pain or failure of medical management. The additional use of instrumentation is still controversial, but might fight infection and yield stability. The purpose of this retrospective study was to evaluate the outcome of 16 cases of non-tuberculous thoracic or lumbar spondylodiscitis treated with anterior debridement and reconstruction (tricortical graft or titanium mesh cage), combined with single-stage posterior instrumentation and grafting. The pathogens identified were: Brucella (5), coagulase-negative Staphylococcus aureus (4), Staphylococcus aureus (3), unidentified (4). All 16 infections resolved without recurrence. Bony union was obtained in all cases. Fourteen out of 16 patients (87.5%) were completely relieved of pain and fully active, an excellent result according to Macnab's criteria; the other two patients obtained a good result. All 7 patients who had a neurological deficit improved. There were two superficial infections, which healed with debridement and antibiotics. A single iliac vein injury was primarily repaired. In conclusion, the proposed technique is an effective and safe treatment for pyogenic spondylodiscitis, if surgery is mandatory.
