Establishing causes of compressive pain syndrome in patients after lumbar diskectomy as assesed by MRT

The aim of our study was to increase diagnosis efficacy in detecting postoperative compression pain syndrome in patients operated on for lumbar disk hernia. The study group consisted of 76 patients who complained of postoperative low-back pains and 31 control subjects with no pain syndrome. Vertebroneurologic assessment and MR-tomography were performed in all studied patients in the pre- and postoperative periods. Postoperative compression pain syndrome was found to be caused by symptomatic or asymptomatic disk pathology and by combined effect. The most common cause of lumbar pain was the disk hernia recurrence. MR images of postoperative neurocompression substrates had sensitivity, specificity and accuracy of 100%, 95.8% and 95.8% respectively. Prognostic value of positive and negative outcomes was 95.8% and 100% respectively.
