Abstract:
Objective:To investigate the clinical effects of anterior cervical discectomy and fusion combined with zero-profile anchored spacer (ROI-C) application on cervical spondylosis.Methods:Eighty-nine patients, consisting of 58 males and 31 females, who received anterior cervical discectomy and fusion combined with zero-profile anchored spacer (ROI-C) application in First People's Hospital of Guiyang from May 2015 to May 2018 were retrospectively analyzed. A total of 138 segments were fused. Operative time, intraoperative blood loss, postoperative complications and their incidence were recorded. The Japanese Orthopaedic Association score, Visual Analogue Scale score, and Neck Disability Index score were used to evaluate clinical effects of anterior cervical discectomy and fusion combined with ROI-C application. Imaging examination was performed to determine cervical curvature, intervertebral space height of fused segments, interbody fusion rate and changes in adjacent segments. The stability and long-term effects of postoperative cervical spine were evaluated.Results:All 89 patients were followed up for (25.6 ± 6.8) months (range 12-36 months). In 53 patients who underwent single-segment fusion, operative time was (85.54 ± 12.53) minutes and the amount of blood loss was (58.45 ± 10.24) mL. In 25 patients who underwent two-segment fusion, operative time was (115.57 ± 16.42) minutes and the amount of blood loss was (92.62 ± 12.44) mL. In 9 patients who underwent three-segment fusion, operative time was (148.63 ± 19.42) minutes and the amount of blood loss was (118.54 ± 11.25) mL. In 2 patients who underwent four-segment fusion, operative time and the amount of blood loss were 188 minutes and 175 mL, respectively in one patient and they were 214 minutes and 225 mL in another patient, respectively. With time went during 1 week to 12 months after surgery, Japanese Orthopaedic Association score was greatly increased, Neck Disability Index score was remarkably decreased, and Visual Analogue Scale score was also significantly decreased ( F = 11.25, 26.35, 20.26, all P < 0.05). Swallowing discomfort occurred in only 2 (2.2%) patients. No patients had incision hematoma, infection, hoarseness or choking cough. At 1 week to 12 months after surgery, cervical curvature and the height of intervertebral space of fused segments were superior to those before surgery (both P < 0.05). At 12 months after surgery, X-ray examination revealed bony fusion with no loosening and displacement of fusion cage and no obvious degeneration of adjacent segments. Conclusion:Anterior cervical discectomy and fusion combined with ROI-C application for the treatment of cervical spondylosis exhibits great therapeutic effects because it can greatly alleviate patient symptoms and improve cervical function.
