Abstract:
BACKGROUND:With the extensive application of anterior titanium plate, postoperative complications such as dysphagia, titanium loose, screw exit and disc degeneration of neighboring segments induced more and more attention of researchers. However, the application of anterior cervical cage is expected to avoid these complications. ＜br> OBJECTIVE:To observe primary curative effect of anterior cervical cage ROI-C in anterior cervical spine surgery. ＜br> METHODS:A total of 32 patients with cervical spondylosis were treated with anterior cervical cage ROI-C in the Wuxi Ninth Hospital Affiliated to Soochow University from April to December 2013. The cage was implanted to promote interbody fusion. Of 32 cases, 23 cases affected cervical spondylotic myelopathy, 2 cases affected nerve root type cervical spondylosis, 3 cases affected cervical hyperextension injury, 1 case affected cervical disc herniation, 2 cases affected cervical instability and 1 case affected segmental cervical ossification of the posterior longitudinal ligament. Japanese Orthopaedic Association and NDI scores were determined to assess neurological symptoms and functional improvement before internal fixation and during final fol ow-up. Simultaneously, adverse reactions were recorded. ＜br> RESULTS AND CONCLUSION:A total of 32 patients finished the regular fol ow-up for 4 to 8 months. Clinical symptoms and spinal cord function of al patients were obviously improved. No ROI-C loosing or displacement or secondary surgery was found. The average fusion time was 4.2 months (3 to 5 months). Mean score of Japanese Orthopaedic Association was increased from 9.2 points pre-surgery to 13.8 points post-surgery. Japanese Orthopaedic Association and NDI scores were higher during final fol ow-up than before fixation (P＜0.05). These data indicated that ROI-C effectively restored intervertebral height in anterior cervical spine surgery, stably reconstructed cervical vertebra, obtained interbody fusion, effectively avoided related surgical complications induced by plate implantation, improved neurological symptoms and function, and showed good short-term effects.
