Cervical Spondyloptosis Successfully Treated with Only Posterior Short Segment Fusion Using Cervical Pedicle Screw Fixation.
Neurol Med Chir (Tokyo) 2019; 59(1):33-38NM

Abstract

This paper describes two patients with cervical spondyloptosis with severe spinal cord injury treated with cervical pedicle screw (CPS) through a single-stage operation, posterior approach. A 60-year-old male patient with quadriparesis due to trauma 1 day before visited the emergency room. Cervical spine computed tomography (CT) and magnetic resonance imaging showed complete dislocation of the C7 and T1 vertebrae with severe spinal cord compression, disc injury, and disc herniation at the C7-T1 level. Cervical pedicle screw with freehand technique was done on C6 and T1 vertebrae, and bilateral distraction for a reduction was performed with a screw distractor. After reduction of the C7 vertebra on the surgical field, CPS placement on C7 body was done. After surgery, follow-up X-rays showed near complete reduction. The patient completed a rehabilitation program, and his condition improved. From the third month postoperatively, the patient could ambulate without assistance and perform nearly normal daily activities. A postoperative CT scan 1 year later showed accurate screw position and complete fusion bridges on the C6-C7-T1 vertebrae. The other patient, a 39-year-old male, also showed C7-T1 spondyloptosis with quadriparesis (grade IV). C6-T1-T2 fusion surgery was performed only through a posterior approach. The patient showed nearly normal neurology and reduction. Considering early surgery time followed by open reduction and biomechanical superiority of CPS, single posterior approach and short segment fusion appear to be a great surgical method.
