BackgroundAlthough the cervical pedicle screws and rods were used for atlantoaxial instable, the axis fractures still a challenge for spine surgeon. ObjectiveThis study was to evaluated the clinical outcomes of axis burst fractures had C1C3 pedicles screws fixation treatment. MethodsFrom June 2014 to July 2018, 45 patients with axis fractures were enrolled in this study; 23 patients was odontoid underwent C1C2 pedicles screws fixation, and 21 patients was odontoid combine body fractures had C1C3 pedicles screws fixation. The clinical outcomes of pain relief (visual analog scale, VAS), functional disability (neck disability index, NDI) were recorded at baseline and at the final follow-up. ResultsThe pain index and NDI were all significantly improved when compared to pretreatment (P < 0.01).The VAS and ND were no significant difference between two groups (P > 0.05). All patients, suffered from severe mechanical upper cervical neck pain at pre-operative, were pain free post-operation. Preoperative neurological examination was normal in all patients, and remained the same after surgery.All cases showed normal neurological function at the final follow-up. No vascular or neurological complication was noted. The fracture healing and the bony union of the fixed segments were revealed in all cases on CT views. Implant failure and instability were not seen on lateral flexion/extension radiographs of the cervical spine. ConclusionsCervical pedicle screws fixation was effective and safe procedures in the treatment of traumatic spondylolisthesis of axial fractures. The atlantoaxial instable of axis burst fractures can be managed with C1-C3 pedicles screws fixation.

“…Neurological injuries are uncommon since the large diameter of the spinal canal is further widened by centrifugal displacement of fragments. 4 Standard radiographs of occipito-cervical junction are often inadequate and overlook these fractures. Hence, a high index of suspicion must be maintained in patients with neck pain who have sustained axial compression injuries.…”

Direct Fixation of C1 Jefferson Fracture Using C1 Lateral Mass Screws: A Case Report

et al. 2019

View full text Add to dashboard Cite

Background: Jefferson fractures are classically described as burst fractures of C1. Traditional surgical treatment of these unstable fractures is either occipito-cervical or posterior C1-C2 fusion, resulting in a significant loss of range of cervical neck movement. This case report discusses the fixation of a Jefferson fracture using C1 lateral mass screws to achieve surgical stabilization while preserving the range of movement. We aim to add to the body of evidence supporting this fixation method. Methods: A 39-year-old male presented to our emergency department with an unstable Jefferson fracture caused by trauma. The various treatment options, such as cervical collar, HALO immobilization, occipito-cervical fusion, and atlanto-axial fusion and direct fixation of C1, were evaluated and discussed with the patient. Informed consent was obtained from the patient prior to writing this case report. Results: At 3 months postoperation, the patient demonstrated near full range of movement in his neck. He had also resumed driving. By 6 months, the patient returned to work, and at 12 months, imaging confirmed union. Conclusions: This case report adds to the body of evidence supporting the technique of C1 lateral mass screws for direct stable fixation of Jefferson fractures. This fixation method preserves the cervical spine range of motion with minimal functional restriction.

Anterior stabilization of the CI―CIII vertebrae after transoral removal of an aggressive aneurysmal bone cyst of the CII vertebra (a case report and literature review)

Лечение пациентов с атлантоаксиальной нестабильностью, вызванной различными заболеваниями области основания черепа и краниовертебрального перехода, сочетающимися с вентральной компрессией ствола головного мозга, является трудной и неоднозначно решаемой задачей. Мы демонстрируем случай поэтапного лечения, важнейшим компонентом которого явилось успешное трансоральное удаление агрессивной аневризмальной кисты СII позвонка с выполнением из этого же доступа передней стабилизации СI-СIII сегмента позвоночника индивидуальной системой. Клинический пример. Пациент, 31 год, с деструкцией тела и зубовидного отростка СII позвонка, пораженных агрессивной аневризмальной костной кистой с нарушением целостности задней стенки тела и зубовидного отростка СII позвонка, клинически проявляющейся ограничением подвижности и болью в шейном отделе позвоночника. Результаты. Выполнено трехэтапное оперативное вмешательство. Сначала осуществлены пункционная биопсия тела СII позвонка субмандибулярным доступом и задний окципитоспондилодез металлоконструкцией от уровня затылочной кости до СIV позвонка. Через 2 мес после этого произведены трансоральное удаление патологического очага тела и зубовидного отростка СII позвонка и передняя стабилизация из этого же доступа СI-СIII сегмента позвоночника с использованием индивидуальной накладной металлической системы. Через 2 нед после второй операции произведен перевод окципитоспондилодеза в систему задней стабилизации СI-СIII. Контрольная КТ через 8 мес после операции показала правильное стояние обеих систем стабилизации. Выводы. Использование индивидуального устройства для передней стабилизации СI-СIII позвонков при различных заболеваниях области краниовертебрального перехода является эффективной и перспективной методикой. Ключевые слова: трансоральный доступ, передняя стабилизация СI-СIII сегмента позвоночника, агрессивная аневризмальная киста.
