Direct C1 posterior arch screws for reduction and osteosynthesis in the treatment of Jefferson fracture.

Abstract

The surgical treatment of Jefferson fractures generally involves solid fusion, which limits the range of motion of the upper cervical spine. Herein, we present a case of a Jefferson fracture that was surgically treated using direct C1 posterior arch screw reduction and osteosynthesis instead of fusion surgery. Postoperative computed tomography (CT) and plain radiography revealed that both C1 posterior arch screws were well positioned, and placing lag screws at the C1 level played a key role in fracture reduction. The present case highlights a surgical technique, which can preserve neck motion by using lag screws for reduction and osteosynthesis.
