| Cage and Plate | Device | anterior cervical discectomy and fusion is performed using cervical cage and plate |
|
| Cage alone | Device | anterior cervical discectomy and fusion is performed using cage alone with plate. |
|
a specific questionnaire is used for assessment for dysphagia after anterior cervical discectomy and fusion. For comparison of dysphagia rates(%) between two group, Chi-square analysis is used. Furthermore, odds ratio of each variable for dysphagia is calculated for logistic regression analysis.
| one year after surgery |
| risk factors of dysphonia | a specific questionnaire is used for assessment for dysphonia after anterior cervical discectomy and fusion. For comparison of dysphonia rates(%) between two group, Chi-square analysis is used. Furthermore, odds ratio of each variable for dysphonia is calculated for logistic regression analysis. | one year after surgery |
| factors for quality of life | Firstly, total cost is calculated for each case. European Quality of Life-5 Dimensions is also used for assessment of quality of life after operation. Between two groups, quality of life per cost is evaluated. | one years after operation |
| risk factors for adjacent segment degeneration | The rates (%) of radiological and clinical adjacent segment degeneration is evaluated using X-ray and clinical evaluation in both groups. For statistical analysis, Chi-Square test is used for comparison of rates (%) for adjacent segment degeneration. Furthermore, logistic regression test is also used for calculating odds ratio for adjacent segment degeneration | five year after surgery |
| correlation between osteoporosis and fusion | The rates (%) of fusion is evaluated in relation to osteoporosis. For statistical analysis, Chi-Square test is used for comparison between osteoporosis group and non-osteoporosis group. | one year after surgery |
| relation between brace wearing and fusion | The rates (%) of fusion is evaluated using X-ray and CT scan according to kinds of brace in both groups. For statistical analysis, Chi-Square test is used for comparison of fusion rates (%). | one year after surgery |
| surgical outcomes for combined uncinectomy | In relation with uncinectomy, the clinical outcomes (VAS, NDI) and radiological outcome (fusion rates(%)) is compared using t-test and Chi-square test. | one year after surgery |
| change of neck motion after surgery | Serial changes of whole cervical neck motion (degree) is evaluated and compared between pre- and post-operative states. statistical significance is evaluated using one-way ANOVA or paired t test. | one year after surgery |
| neuropathy after anterior cervical discectomy and fusion surgery | The occurrence rates(%) of neuropathic pain is evaluated using a specific questionnaires. Several factors to be associated with neuropathic pain is evaluated using logistic regression analysis. | one year after surgery |
| relation between the method of bone graft and fusion | The rates (%) of fusion is evaluated using X-ray and CT scan according to methods of bone graft in both groups. For statistical analysis, Chi-Square test is used for comparison of fusion rates(%) in relation to the bone graft method. | one year after surgery |
| analysis of complication rates after anterior cervical discectomy and fusion surgery | After anterior cervical discectomy and fusion, complication rates (%) was evaluated, and this is compared between two groups. Further, factors to be associated with complication rates is assessed using Chi-square test | one year after surgery |
| The correlation between existence of co-morbidity and surgical outcome | The clinical and radiological outcomes is evaluated using VAS, NDI, and X-ray in relation with existence of coexistence. T-test and Chi-square test are used for statistical analysis for comparison between co-morbidity group and non-co-morbidity group. | one year after surgery |
| The correlation analysis between smoking history and surgical outcome (fusion rates, improvement of pain and disability) | The surgical outcomes such as fusion rates(%), VAS, and NDI score were evaluated in relation with smoking history. For analysis, Chi-square and t-test are used for comparison between smoking group and non-smoking group. | one year after surgery |
