Motion preserving fixation of an unstable Jefferson fracture using C1 lateral mass screws and rods: A case report

Figure 1 Preoperative and direct postoperative computed tomography scan. A: Preoperative computed tomography (CT) scan showing the displaced fractures involving both the anterior and posterior arches of the atlas; B: Direct postoperative CT shows reduction of the fracture with appropriate positioning of the lateral mass screws and rods.

Figure 2 Re-examination 1 year and 9 months postoperative. A: 1 year and 9 months Postoperative computed tomography scan shows bony union of the posterior arch with satisfactory consolidation; B: 1 year and 9 months dynamic flexion-extension cervical radiographs show atlantoaxial stability.

Figure 3 One year and nine months postoperative clinical examination show full cervical range of motion to the end point.
