Abstract

Abstract:

BACKGROUND: ADD plus-winged adjustable replacement system has the advantages of artificial vertebral body and anterior fixation plate integration and artificial vertebral body height-adjustable, as well as simple to operation, shorter operative time, and good histocompatibility, which make it attract more trust of the surgeons.
OBJECTIVE: To explore the effect of ADD plus-winged adjustable replacement system in cervical anterior decompression, fusion and graft and internal fixation for the treatment of lower cervical spine fracture dislocation combined with spinal cord injury.
METHODS: The ADD plus-winged adjustable replacement device was used in anterior reduction, decompression, fusion and graft and internal fixation for the treatment of lower cervical spine fracture dislocation combined with spinal cord injury in 12 cases. Clinical evaluation and imaging examination were performed at 3, 6 and 12 months after treatment, and then annually thereafter.
RESULTS AND CONCLUSION: All patients were followed-up for 18 months. During the follow-up period, the patients got solid osseous fusion, the regulator was in good position without loosening or fracture; the cervical intervertebral height and physiological curvature were corrected, and the recovery degree of postoperative patient feel and motor function was increased significantly. One case appeared hyponatremia, and no postoperative complications were observed in other patients. The ADD plus-winged adjustable replacement system used in anterior cervical open reduction, internal fixation, decompression and fusion for the treatment of lower cervical spine fracture dislocation combined with spinal cord injury has the advantages of simple and safe operation, good histocompatibility and significant internal fixation effect.
