SEQUESTRATION OF MULTI-LEVEL HERNIATED LUMBAR INTERVERTEBRAL DISCS

Abstract

The aim of this study was to analyze variants of sequestration of multi-level herniated lumbar intervertebral discs and their neurological disorders. Material and methods. The study included a survey of patients and evaluation of clinical data taking into account the results of neuroimaging of the lumbar spine by CT and MRI. Results . Cases of high-level radicular compression with sequestration of the lumbar intervertebral disc prevailed in men (67.4 %). Men had the most common size of the sequestered herniation in both the upper and the lower level within the range of 7-9 mm (11 cases- 30.6 % and 5 cases- 13.8 %, respectively). The same ratio was typical for women: the size of 7-9 mm prevailed in pairs of top and bottom hernias (5 cases - 31.3 % and 4 cases - 25.0 %, respectively). Conclusion . We have defined the clinical symptoms which can be used as markers of sequestration of herniated intervertebral disc (biradikulopathy L₄ and S₁ - 31.0 % and L₄ and L₅ - 13.0 %). Data on the most frequent level of sequestrum (L_IV-L_V - 48.1 %) and the prevailing caudal direction of sequestration (84.6 %) will facilitate the verification of the pathology in the evaluation of CT scans.
