An analysis of the safety and efficacy of dexmedetomidine in posterior spinal fusion surgery for adolescent idiopathic scoliosis: a prospective randomized study.

Purpose: To evaluate whether use of dexmedetomidine, a centrally acting α2 adrenergic agonist, reduces opioid consumption in PSF.

Methods: Adolescent idiopathic scoliosis patients who underwent PSF were randomized into morphine (M) and dexmedetomidine (D) group. M group received a 10 μg/kg/h IV infusion of morphine for 24 h post-surgery, while the D group received a 0.

Progressive hemiparesis due to spino-laminar anomaly of the axis-a case report and literature review.

Introduction: Some of the most common developmental malformations of the axis include anomalies of the odontoid, for example, hypoplasia or aplasia. Isolated anomalies of the posterior arch of the axis rarely occur. This study reports a unique case of congenital anomaly of the neural arch of the axis vertebra, which manifested clinically as progressive hemiparesis.

Prognostic utility of magnetic resonance imaging (MRI) in predicting neurological outcomes in patients with acute thoracolumbar spinal cord injury.

Purpose: Utility of MRI for predicting neurological outcomes in acute cervical spinal cord injury (SCI) is well established but its value in thoracolumbar (TL) SCI needs to be evaluated.

Methods: Seventy-six patients operated for acute TL spinal injuries between January 2014 and March 2016 were reviewed to obtain demographic details, neurology at admission and at the final follow-up. Patients were divided based on the neurology at presentation into group 1 (ASIA A), group 2 (ASIA B, C, D) and group 3 (normal neurology).
