“…If there is a difference in the variance between sensitivity and specificity then that of specificity appears to be larger. Three or four of the six reports have a larger confidence area than the reports of Meyenhorst [16] and Fries et al [19], which have larger patient samples. It is noted that the area of the ellipses is inversely proportional to the sample size and it also depends on sensitivity, specificity and prevalence.…”

Literature data on the diagnostic performance of phlebography, myelography, and CT scan applied to patients with suspected lumbar disk herniation (LDH) are analyzed to extract maximal information about their relative discriminatory power. Seventeen papers meeting the selection criteria contain 13 reports on myelography, 6 on phlebography, and 5 on CT. Sensitivity and specificity are considered simultaneously in logistic ROC space. The reports of each procedure are effectively summarized by a linear regression in logistic ROC space. Taking into account the individual confidence regions of sensitivity and specificity obtained from each report, the slope of the regression line is estimated by Generalized Least Squares (ML). This approach also allows to test the assumption of a common odds ratio (i.e., of a unit slope). The simply to determine common odds ratio as well as the perpendicular distance between the origin and the regression line (as a good approximation to the area under the ROC curve) are used as a measure for the discriminatory power of the procedures. For CT, homogeneity of sensitivity turns out to be much more likely than a common odds ratio. Based on the available, retrospective data, phlebography appears to have the highest performance in visualizing an LDH, followed by myelography and CT.

“…In this study, rostral migrations were observed in 27% of the patients, and caudal migrations were observed in 73%. Previous studies reported heterogeneous results and put forward different hypotheses [10,11]. Fries et al [10] hypothesized that extruded disk fragments might have a higher chance of rostral migration because a greater rostral anterior epidural space is available [10].…”

Fries et al [10] hypothesized that extruded disk fragments might have a higher chance of rostral migration because a greater rostral anterior epidural space is available [10]. Schellinger et al [11] suggested that the chance of the extruded disk fragments migrating rostrally and caudally seems to be the same because the rostral and caudal anterior epidural spaces are morphologically similar.…”

“…Schellinger et al [27] suggested that the Herniated Nucleus Pulposus (HNP) appears to have an equal chance of moving cranially or caudally because the structure of the Anterior Epidural Space (AES) is the same at both superior and inferior halves of the vertebral body. Whereas Fries et al [26] assumed that a higher rate of cranial migration of herniated disc material may occur because of greater space available to contain herniated nucleus pulposus in the anterior epidural. M.Daghighi et al [14] Found that there is a higher incidence of cranial lumbar migration in older patients.…”

The conventional open discectomy is the gold standard for treating extruded lumbar disc herniation, especially in highly migrated lumbar disc herniation. Endoscopic spine surgery is known to be very challenging and technically demanding, in particular for highly migrated disc herniation. However, several studies have reported numerous effective techniques with results approximatively equal to conventional open surgeries or mini-open surgery. In the last few years, an increased number of endoscopic spine surgical techniques have been proposed in order to overcome various issues encountered in traditional endoscopic spine surgery. Nevertheless, surgical approach selection for treating extruded lumbar disc herniation is based on aspects such as anatomical structures, availability of surgical instruments, surgeon’s experience, and the disc herniation location. Advances in endoscopic visualization and instrumentation, as well as an increased demand for minimally invasive procedures, have led to the popularity of Percutaneous Endoscopic Lumbar Discectomy (PELD). PELD is a recent and advanced technique among other minimally invasive spine surgeries (MIS). It includes various kinds of surgical techniques to treat lumbar disc herniation and aims to offer a safe, less invasive surgical procedure for lumbar disc space decompression and removal of nucleus pulposus.
