Spinal ependymoma is a benign central nervous system tumor described as an intramedullary lesion more frequently located at the conus medullaris. It has been described exceptionally in the literature as an intradural extramedullary tumor. ⋯ All of the previously reported cases of spinal intradural extramedullary ependymomas carried out a benign course. The case we are reporting is the first one in which malignant transformation occurred. This tumor should be taken into account in the differential diagnosis of intradural extramedullary lesions. Moreover, close follow-up is recommended for this unusual location of ependymomas.

A cross-sectional survey was conducted using face-to-face interviews. ⋯ In comparison with other developing countries, point prevalence of LBP is higher in Turkey and approximates to prevalence estimates of LBP in developed countries. Smoking may be associated with both occurrence and severity of LBP. Although piety is not associated with having LBP, religious people are more likely to have restricted activity related to LBP.

Case Reports
Posterior transcanal lumbar interbody fusion for septic vertebral fracture pseudarthrosis and sitting imbalance.
Case report. ⋯ This extremely rare case focuses on the use of the transcanal approach to treat adequately lumbar septic pseudarthrosis and restore lumbar lordosis in definitively paraplegic patients in whom no anterior approach can be used.

A retrospective evaluation and characterization of the trajectory of atlantoaxial transarticular screws inserted using an aiming device. ⋯ The atlantoaxial transarticular screw was inserted safely as aimed by using the aiming device. The trajectory was characterized by less bone thickness dorsal to the screw on lateral radiogram, which should be a new intraoperative landmark for screw insertion, in place of the anterior arch of C1.

Case Reports
Ossification of the posterior atlantoaxial membrane and the transverse atlantal ligament.
Case report. ⋯ Ossification of various parts of the spinal ligament have been reported previously. Among them, ossification of both the PAAM and TAL has never been reported previously and is thus extremely rare. Surgical intervention improved the neurological impairment.
