title: [Preoperative, neuropathic component in patients with back pain].
abstract: BACKGROUND
  The objectification of pain is essential for evaluation, treatment plan and follow-up; therefore, it is necessary to find reliable clinical parameters.
  
  
  OBJECTIVE
  The goal of the study was the preoperative screening of a neuropathic component in patients with vertebral compression fracture (WKF), herniated disc (NPP) or spinal cord compression (SKS).
  
  
  METHODS
  Depending on the preoperative condition on admittance, patients were classified into three groups: group 1 WKF, group 2 NPP and group 3 SKS. To characterize the pain we used the painDETECT questionnaire, the Oswestry questionnaire and further questionnaires. All patients were surgically treated according to the diagnosis, e.g. radiofrequency kyphoplasty, nucleotomy or spondylodesis.
  
  
  RESULTS
  We evaluated the data from 139 patients (45% WKF, 34% NPP and 21% SKS). There were no differences in preoperative pain intensity (median ordinal scale 0-10) with a mean preoperative score of 7 for all groups. The total score of the painDETECT questionnaire showed significantly higher results in group 2 (median 18) and in group 3 (median 14) than in group 1 (median 9). There was even a significant difference between groups 2 and 3 (p = 0.03). The highest pain intensity was detected in group 1 with a median visual analog scale (VAS) of 71 mm. The total scores in the painDETECT questionnaire and the scores in the Oswestry questionnaire correlated in groups 2 and 3.
  
  
  CONCLUSIONS
  The painDETECT questionnaire was shown to be a very suitable instrument for evaluating the neuropathic pain component in patients with dorsalgia. This could be very useful in planning further therapy.
