Abstract: Retrospective study.To support single-level posterior debridement and instrumented interbody fusion as a single-stage procedure for spontaneous pyogenic osteomyelitis/discitis.The best surgical technique for patients with bacterial spinal infections is still a matter of debate. Recent publications suggest that titanium implants can be used safely in the infectious sites in combination with debridement and antibiotic therapy.We retrospectively review patients with spontaneous pyogenic osteomyelitis/discitis in whom medical therapy failed, and they consequently underwent posterior decompression and instrumented fusion. Data was collected regarding demographics, clinical presentation, images and laboratory studies, antibiotic treatment, duration of hospitalization, time to achieve radiologic evidence of fusion, postoperative complications, and neurologic function pre- and postoperatively. Quality of life was measured using the EQ5D questionnaire and level of disability with the Oswestry Disability Index.Nine patients, ranging in age from 41 to79 years, with a Frankel score of D in 7 cases and of E in 2 cases, underwent a single-level/single-stage debridement and posterior instrumented fusion with pedicle screws and an interbody and posterolateral autogenous bone graft. Preoperative neurologic deficits improved in all the cases and solid bone fusion was achieved in all 9 patients at 12 months. The mean follow-up period was 67 months. The infection healed after surgery in all the patients and they did not require a second operation to remove the metal implants. Quality of life assessed with the EQ5D questionnaire showed scores ranging between 0.70 and 1. The median Oswestry Disability Index was 15.5%.These findings support that debridement and posterior instrumented fusion can be performed as a single-stage procedure with no increase in the recurrence rate or morbidity. The outcome has been satisfactory in our patients in terms of the rate of fusion and quality of life.
