STUDY DESIGN: Prospective clinical study. OBJECTIVE: To identify changes in @entity308 and @entity148 after cervical total disc replacement (CTDR) among @entity1 with @entity4720 , and to investigate their effects on the prognosis. SUMMARY OF BACKGROUND DATA: Previous researches have reported relationships between @entity1316 and lumbar surgery. There have been no previous studies on the effects of @entity308 and @entity148 on the CTDR outcome at the 2-year postoperative phase. METHODS: Eighty-five @entity1 with @entity4720 who underwent CTDR were included. @entity1 were evaluated preoperatively and at 6 postoperative time points, including 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years. @entity308 and @entity148 were evaluated by using the Zung Self-Rating @entity308 Scale and the Zung Self-Rating @entity148 Scale. Neurological function was evaluated by using the visual analogue scale and the Japanese Orthopaedic Association. The quality of life was assessed by a 36-item Short-Form Health Survey. A Spearman rank correlation analysis was used. RESULTS: All @entity1 had improvements in clinical symptoms and neurological function. Twelve (14.12%) @entity1 had symptoms of @entity308 and 21 (24.71%) @entity1 had symptoms of @entity148 . There was a significant difference between the preoperative and the postoperative Zung Self-Rating @entity148 Scale scores, whereas the Zung Self-Rating @entity308 Scale scores were not significantly different over time. For all @entity1 , the visual analogue scale scores and the 36-item Short-Form Health Survey scores were associated with the postoperative level of @entity308 and @entity148 but not age or the Japanese Orthopaedic Association score. CONCLUSION: Some @entity1 with @entity4720 have preoperative @entity308 and/or @entity148 . CTDR may provide some improvements in these @entity1109 . The presence of @entity308 and/or @entity148 may have a negative influence on the @entity1 's prognosis. LEVEL OF EVIDENCE: 3.
