The surgical care on the single cervical open-door laminoplasty with Centerpiece plate fixation

Abstract

Objective To summarize the C3～7 the single cervical open-door laminoplasty with Centerpiece plate ( posterior cervical laminoplasty plate and screw fixation system) internal fixation surgery and nursing characteristics. Methods The surgeries in our hospital from August 2009 to January 2010 was investigate, which were 19 cases of cervical stenosis with posterior C3～7 single cervical open-door laminoplasty and Centerpiece plate fixation. The focused process was discussed, such as preoperative dynamic systems preparation, surgical position, the frame of the placement and intraoperative open the door and plate fixation device. Results 19 cases of posterior C3～7 single cervical open-door laminoplasty and Centerpiece plate fixation surgeries were uneventful and none of the reason for body position and power systems affected the surgical process. Operative time was 95～130 minutes, with an average time of 105 minutes; intraoperative blood loss was 290 ml; intraoperative C-arm X-ray confirmed Centerpiece plate in a good position. However, 1 patient appeared cerebral fluid leakage after operation and 7 patients appeared mild pain in the shoulder and neck accompanied by stiffness symptoms. There were no spinal cord injuries and complications such as hematoma. After 1 to 6 months follow-up there were no screw fixation instability, loosening, plate shift, and lamina phenomena occurred and the neurological function in patients recovered well. Conclusions The single cervical open-door cervical laminoplasty with Centerpiece plate technique is the better treatment of cervical stenosis as a surgical method. Mastering the use of Mayfield head frame, displaying good posture, getting a good knowledge of surgical procedures, preparing and using well the power system contribute to the operation completed successfully.
