Surgical Treatments for Lumbar Spine Diseases (TLIF vs. Other Surgical Techniques): A Systematic Review and Meta-Analysis.

Objective: The purpose of this study is to compare fusion rate, clinical outcomes, complications among transforaminal lumbar interbody fusion (TLIF), and other techniques for lumbar spine diseases.

Design: This is a systematic review and meta-analysis.

Data Sources: PubMed, EMBASE, Scopus, Web of Science, and CENTRAL databases were searched from January 2013 through December 2019.

Posterior epidural sequestrated disc presenting with contralateral radiculopathy: a very rare case.

Introduction: Posterior epidural sequestrated disc is a fairly uncommon condition. We report a case of an unusual presentation of posterior epidural migration with contralateral symptoms. We emphasize a high index of suspicion for early recognition and treatment to promote a good neurological recovery.

Full-Endoscopic Interlaminar Lumbar Discectomy: Retrospective Review of Clinical Results and Complications in 545 International Patients.

Background: Minimally invasive techniques have been developed to provide access to the disc with better visualization while causing less muscle trauma and its consequences. This study was aimed at evaluating the clinical outcomes and complications of the fully endoscopic lumbar discectomy interlaminar approach in a large number of patients.

Methods: Patients diagnosed with lumbar herniated nucleus pulposus who underwent fully endoscopic interlaminar lumbar discectomy between 2011 and 2016 were reviewed.

Variation of C1 spinolaminar line and prevalence of C1 stenosis in normal population.

Background: The variation of C1 spinolaminar line in normal population is not fully understood. The relative position of C1 lamina to C3-C2 spinolaminar line is reported as good screening tool for determination of C1 canal stenosis.

Objective: To determine the variation of C1 spinolaminar line and find the prevalence of C1 canal stenosis in normal population using C3-C2 spinolaminar test.

Morphological study of subaxial cervical pedicles by using three-dimensional computed tomography reconstruction image.

Malpositioning of cervical screws risks neurovascular injury. A cervical screw fixation system can provide proper rigidity, alignment correction, and high rates of fusion afforded by high pullout biomechanical strength. The objective is to assess the dimensions and axis of the C3-C7 cervical pedicles.
