Abstract:
OBJECTIVE:To investigate the clinical efficacy of zero-profile anchored spacer (ROI-C) in treating cervical spondylosis with osteoporosis.
METHODS:From May 2013 to May 2018, a total of 145 patients with cervical spondylosis were treated by ROI-C through anterior cervical spine approach. Among them, 31 patients were aged ≥60 years and had osteoporosis by bone density measurement, and they were retrospectively analyzed. Including 9 males and 22 females, aged 60-84 years old with an average of (69.12±7.65) years. There were 23 cases of single-segment fusion, 6 cases of two-stage fusion, and 2 cases of three-stage fusion;and 41 devices of ROI-C fusion was placed in the patients. Operation time and intraoperative blood loss were recorded;Japanese Orthopaedic Association (JOA) scores and visual analogue scale(VAS) were respectively used to evaluate the neurological function and neck pain before and after operation. The cervical curvature (expressed as Cobb angle), the height of the intervertebral space at the surgical segment, and the intervertebral fusion were observed at postoperative and follow-up periods were observed by image data.
RESULTS:All patients were followed up for 12-24(15.6±4.4) months after operation. The operation time were from 75 to 113 (101.33±10.25) min and intraoperative blood loss were from 14 to 51 (33.18 ± 16.56) ml. Among these 23 patients with fusion of single segment, the operation time were 75 to 98 (85.47±8.70) min and intraoperative blood loss were 14 to 30(21.18±6.56) ml. JOA scores of all included patients were increased from 9.66±2.12 preoperatively to 14.36±1.24 at the final follow-up (
CONCLUSION:Anterior cervical approach with ROI-C for the treatment of elderly patients with cervical spondylosis and osteoporosis had reliable clinical effect, short operation time, less intraoperative blood loss, and can effectively restore cervical curvature and intervertebral space height, and has advantages of fewer complications and higher successful rate of fusion.
