Background And Objectives: The aim of this study was to examine whether shoulder rotation increases the length of the posterior longitudinal ligament (PLL) in the lateral decubitus position.

Methods: Thirty-four adult male volunteers were placed in the right or left lateral decubitus and flexion position on a horizontal operating table. Thoracic spinal ultrasonography was performed using the paramedian oblique sagittal plane to obtain the optimal ultrasound view for the PLL on the dependent side.

Objective: Spinal fusion operation is an effective treatment in the spinal pathology, but it could change the physiological distribution of load at the instrumented and adjacent segments. This retrospective study compared the radiological and clinical outcomes of patients undergoing lumbar fusion with semirigid rods versus rigid rods system.

Methods: Using transpedicular fixation and posterior lumbar interbody fusion at the level of L4/L5, 20 patients were treated with semirigid rods (WavefleX, SR group), and 20 patients with rigid rods (titanium, RR group).

Background: Laryngoscopic intubation and supraglottic airway device insertion can prolong the corrected QT (QTc) interval during anaesthetic induction even in healthy patients. No prior study has compared the effect of laryngoscopic intubation and supraglottic airway device, i-gel, insertion on the QTc interval change.

Methods: Patients were randomised to either the intubation group (N.
