ROI-C versus traditional fusion cage combined with titanium plate in treatment of cervical spondylosis: cervical stability reconstruction and intervertebral fusion

Abstract

Abstract:

BACKGROUND: Anterior cervical discectomy and fusion is classical and satisfactory for the treatment of cervical spondylosis, but there are still many problems. ROI-C designed with the concept of “zero-notch” has been widely used in clinical practice in recent years, but there are few comparative studies between ROI-C and traditional surgical treatment.

OBJECTIVE: To compare and analyze the clinical effect of ROI-C and traditional fusion cage combined with titanium plate in the operation of cervical spondylosis.

METHODS: From April 2012 to December 2015, 47 cases underwent anterior cervical decompression spondylotic myelopathy fusion and internal fixation surgery. They were divided into two groups. Patients in the titanium plate group (n=18) were treated by traditional fusion combined therapy with titanium plate. Patients in the ROI-C group (n=29) were treated by ROI-C fusion treatment. Informed consent was obtained from all patients. This study was approved by the Hospital Ethics Committee. Intraoperative blood loss, the number of C-arm fluoroscopy, operation time, postoperative complications and intervertebral fusion were recorded. Visual Analogue Scale score and Japanese Orthopaedic Association score were evaluated before and after operation.

RESULTS AND CONCLUSION: (1) All patients were followed up regularly for 12-16 months. Clinical symptoms and spinal cord function of all patients were remarkably improved. Neither of the two groups had implant loosening or displacement or secondary surgery. (2) At the last follow-up, the operative segments were fused, but there was no significant difference between the two groups (P > 0.05). (3) Operation time, intraoperative blood loss and the number of C-arm fluoroscopy during operation were better in the ROI-C group than in the titanium plate group (P < 0.05). (4) Visual Analogue Scale score and Japanese Orthopaedic Association score were better after operation than those before operation in both groups, but no significant difference was found between the two groups at various time points (P > 0.05). (5) ROI-C and the traditional fusion cage with titanium plate can obtain good clinical curative effect in anterior cervical spine surgery. There was no significant difference in effective recovery of intervertebral space height, cervical stability reconstruction and interbody fusion. Nevertheless, ROI-C group has obvious advantages in operation time, intraoperative blood loss and avoidance of complications caused by plate implantation. It is hopeful that ROI-C will replace the traditional fusion cage combined with titanium plate.
