Abstract
We describe a novel and new technique of posterior unilateral lag screw fixation of non-union atlas lateral mass fracture. A 46-year-old man presented with cervical pain and tenderness after a vehicle turn over accident and he was diagnosed to have left atlas lateral mass fracture. He was initially treated by immobilization using Minerva orthosis. About 2 months later, he developed severe neck pain and limitation of motion and thus he was scheduled for operation due to non-union atlas lateral mass fracture. A 28 mm lag screw was inserted under anterior-posterior and lateral fluoroscopic views. The entrance point was at the dorsal aspect of left atlas posterior arc at its junction to the lateral mass, and by using the trajectory of 10 degrees medial and 22 degrees cephalad fracture reduction was achieved. Unilateral lag screw fixation of atlas fractures is an appropriate, safe and effective surgical technique for the management of unilateral atlas fractures.
