Background and purpose

Management of pyogenic spondylodiscitis in adults remains controversial. The aim of this study was to evaluate the results of a minimally invasive method for deformity correction and stabilization of these lesions with percutaneous osteosynthesis.

Methods

Ten patients were included in this study and treated with a two-step procedure: posterior percutaneous osteosynthesis completed by complementary intervertebral grafting via an anterior access. Postoperative evaluation was clinical and radiological with measurement of local sagittal deformity and restitution of vertebral body height.

Results

In this series, bacteriologic identification was possible and pain was controlled in every case. On postoperative evaluation, the implants were always properly positioned. The mean local sagittal deformation was +2.1掳 preoperatively and 鈭?.4掳 postoperatively. The mean increase in vertebral body height was measured at 8 mm postoperatively. At the last follow-up, a moderate loss of correction was noted (mean: 2掳 and 3 mm) and all patients but one showed solid bony fusion.

Conclusion

Percutaneous osteosynthesis in septic conditions in association with an anterior graft provides satisfactory clinical and radiographic results. It provides a valuable alternative for deformity correction and spinal stabilization with a minimally invasive access in patients with comorbidities.
