A prospective, double-blind, randomized controlled trial of treatment of atlantoaxial instability with C1 posterior arches >4 mm by comparing C1 pedicle with lateral mass screws fixation.
BACKGROUND C1 posterior arch screw placement is one of the most effective treatments for atlantoaxial instability (AAI), which can be performed by either pedicle or lateral mass screw fixation. This study attempted to compare the feasibility and clinical outcomes of C1 pedicle with lateral mass screw fixations for treatment of AAI with C1 posterior arches >4 mm. METHODS A total of 140 patient...

متن کاملComplete absence of the posterior arch of C1: Case report
Posterior atlas arch anomalies are relatively common, but have a variety of presentations ranging from partial clefts to complete agenesis of the posterior arch. Partial clefts are prevalent in 4% of patients and are generally asymptomatic. However, complete agenesis of the posterior arch is extremely rare. We report the case of a 46-year-old man who presented with upper cervical spine and occi...
متن کامل[Aplasia of the posterior arches of the atlas: a presentation of 2 cases].
INTRODUCTION Aplasia of the posterior arches of the atlas is an uncommon condition caused by a defect in their closure. It is usually associated with different syndromes. CASE REPORT We present 2 asymptomatic patients with aplasia of C1 posterior bodies. CONCLUSIONS Further studies are required on these lesions in order to take possible protection measures against trauma, and the selection ...
