OBJECTIVE There were previous reports of redundant nerve roots (RNRs) focused on their clinical significance and pathogenesis. In this study, we investigated the significant radiologic findings that correlate with RNRs occurrence. These relations would provide an advanced clue for clinical significance and pathogenesis of RNRs. METHODS Retrospective research was performed with data from 126 p...

Purpose. Incidental durotomy is a relatively common complication for patients undergoing posterior spinal surgery. Delineating anatomical variants in the posterior lumbar spinal canal is crucial in reducing future rates of incidental durotomy. Materials and Methods. The ligamentous attachments between the dura mater and ligamentum flavum in the lumbar region of 17 soft-fixed cadavers were inves...

BACKGROUND AND OBJECTIVES To assess the accuracy of the ultrasound (US) to predict the depth to reach lumbar intrathecal and epidural spaces in order to decrease the number of puncture attempts. METHODS Thirty-one patients (25 males and 6 females), ASA I or II participated in this study. The transversal ultrasound image of the lumbar spine was obtained at the level of the L3-L4 space. An anes...

We report a case of unsuccessful removal of an epidural catheter in a postpartum patient following a labour epidural analgesia, which ultimately required surgical intervention and fenestration ligamentum flavum to remove the epidural catheter. A 26 year old, requested an epidural analgesia for her labour pain. The epidural catheter was inserted under aseptic technique, and she was comfortable t...

OBJECTIVE To investigate clinical-radiological features of cervical myelopathy due to degenerative spondylolisthesis (DSL). METHODS A total of 448 patients were operated for cervical myelopathy at Nishitaga National Hospital between 2000 and 2003. Of these patients, DSL at the symptomatic disc level was observed in 22 (4.9%) patients. Clinical features were investigated by medical records, an...

STUDY DESIGN Retrospective study. PURPOSE The aim of the present study is to analyze the prevalence and distribution of cervical and thoracic compressive lesions of the spinal cord in lumbar degenerative disease, using whole-spine postmyelographic computed tomography. OVERVIEW OF LITERATURE Of the various complications resulting from spinal surgery, unexpected neurological deterioration is ...
