  • Description: PURPOSE OF THE STUDY The purpose of the retrospective study is to analyse a group of patients surgically treated for cervical spondylodiscitis. The first hypothesis states that the removal of infected intervertebral disc without its anterior column reconstruction in the acute phase of infection results in worse clinical and radiological evaluation of the patient. The second hypothesis defines that the use of titanium implant in anterior column reconstruction in the chronic phase of infection increases the risk of recurrent infection. MATERIAL AND METHODS The evaluated group of patients who underwent surgery includes a total of 21 patients (8 females, 13 males) with the mean age of 57.6 years. 12 patients in the acute phase of infection were treated by anterior debridement without disc space reconstruction, of whom four patients were completed by posterior instrumented fusion in the second stage. In 9 patients in the chronic phase of infection radical anterior debridement was completed by anterior titanium implant reconstruction, of whom in five patients posterior instrumented fusion was performed in the second stage. All patients were clinically evaluated by mJOA, VAS and Frankel score preoperatively, at 6 months and at 1 year postoperatively. The radiologic evaluation assessed the instrumentation failure, spinal fusion and kyphosis progression measured by sagittal Cobb angle. RESULTS The mJOA values improved from the mean preoperative value of 1.6 to 13.15 (6M) and 13.3 (1Y) postoperatively (p = 0.055). The VAS score increased from the mean value of 8.5 preoperatively to 2.15 (6M) and 1.35 (1Y) postoperatively (p < 0.001). No patient reported worse neurological finding postoperatively. The kyphosis progression measured by sagittal Cobb angle from the preoperative +6.7 decreased to +3.2 degrees at 1 year after surgery. The group of 12 patients treated in the acute phase of infection by anterior debridement without anterior column reconstruction showed worsening of kyphosis from +1.1 before surgery to +1.6 degrees at 1 year after surgery. The group of eight patients treated in the chronic phase by anterior debridement and reconstruction of the anterior column by implant changed from +15.9 before surgery to +6.1 degrees at 1 year after surgery. In two out of 12 patients with neurological deficit, the T2-weighted MRI finding of signal hyperintensity showed no improvement of the neurological deficit. DISCUSSION In the group of all operated patients, neither the worsening in the clinical evaluation using the mJOA or VAS score, nor kyphosis progression measured by Cobb angle in the sagittal plane, or failure of instrumentation in the anteroposterior procedure were reported postoperatively. In a total of nine patients operated on during the chronic phase of infection, in whom titanium implant was used to reconstruct the anterior column defect, no recurrent deep infection was observed. CONCLUSIONS In the acute phase we prefer anterior debridement with epidural abscess evacuation without anterior column reconstruction and posterior instrumented fusion in case of kyphosis progression in the second stage. In the chronic phase, radical anterior debridement with titanium implant reconstruction, eventually with posterior instrumented fusion is preferred. Key words: cervical spondylodiscitis, epidural abscess, anterior debridement, bacterial biofilm.
