摘　　要：目的探讨Bryan人工颈椎间盘置换术在无骨折脱位脊髓损伤患者中应用价值。方法采用Bryan人工颈椎间盘置换术治疗50例无骨折脱位脊髓损伤患者(存在创伤诱因5例),比较有、无创伤诱因患者的临床效果。结果创伤与无外伤组在术前及末次随访置换节段活动度上比较均无统计学差异;创伤组术前及末次随访置换节段均无不稳定;创伤组JOA术前值及末次随访值均较无创伤组低,两组在JOA改善率上无统计学差异。结论对于无骨折脱位脊髓损伤患者,当压迫节段局限、无病变节段不稳定,颈椎人工间盘置换术也是一种有效的治疗策略。Objective To evaluate the effect of Bryan artificial disc replacement on cervical spinal cord injury without radiographic abnormality. Methods 50 patients who under went cervical disc replacement from December, 2003 to December, 2005 were investigated （ Male 35, Female 15）. The age of patients was from 25 to 73, the average is 48.9. Among those patients, 5 had traumatic experience. The clinical outcome was compared between the two groups. Results Follow up period were from 36.0 to 55.6 months after operation, averaged 42.9months. The range of motion in sagittal direction of the operated level before operation and at the time of final follow-up had no significant difference between the two groups. In the traumatic group, there was no evidence for instability at the operated level before operation and at the time of final follow-up. Compared with the no traumatic group the preoperative and postoperative JOA socre were less, but the ameliorate rate of JOA score had no statistic difference between two groups. Conclusion Bryan artificial disc replacement is a good choice for the cervical spinal cord injury without radio graphic abnormality when the spinal cord compression is less than two levels and there is no evidence of instability.
