| 摘要： |
| 目的 观察不同手术时期Bryan人工椎间盘置换术后置换节段脊柱功能单位 （functional spine unit，FSU）曲度变化情况。方法 随访2003年12月~2007年12月接受单节段Bryan人工椎间盘置换术的患者，在侧位X线片上测量FSU角度变化。结果 60例患者获得随访，随访3~69个月，平均32个月，手术节段包括C3/C4节段2例，C4/C5节段14例，C5/C6 节段41例，C6/C7节段3例。术前FSU平均曲度为0.3°，末次随访时为-0.5°（P<0.05）。根据手术日期将全部病例分成早期（2003~2004年）、中期（2005年）和后期（2006~2007年）3组，统计分析发现早期病例随访时FSU后凸平均增加1.6°，后期病例FSU后凸平均增加仅0.1°，2组的FSU角度变化差异有统计学意义（P<0.05）。结论 Bryan人工颈椎椎间盘置换术术后FSU后凸主要发生在早期病例，通过经验的积累和手术技术的改进可以避免术后FSU后凸。 |

| Abstract: |
| Objective To investigate the angle changes of functional spine unit (FSU) at operated segment after single-level Bryan disc replacement at different time points after operation. Methods A total of 60 patients receiving single-level Bryan disc replacement between December 2003 and December 2007 were enrolled in this study. The changes of FSU angle were measured and compared on lateral X-ray films. Results All 60 patients were followed up for an average of 32 months (ranging 3-69 months). The levels of surgery included C3/C4 (2 cases), C4/C5 (14 cases), C5/C6 (41 cases) and C6/C7 (3 cases). The mean FSU angle was 0.3° before the surgery, and -0.5° at the final follow-up, with statistically significant difference found between them (P<0.05). The patients were divided into three groups according the operation period: early stage group (2003-2004), middle stage group (2005) and late stage group (2006-2007). The average FSU kyphosis was increased by 1.6° after the operation in early stage group, but only by 0.1° in late stage group,and the difference had statistical significance (P<0.05).Conclusion FSU kyphosis mainly occurs in early stage after Bryan disc replacement. This complication could be avoided with surgical experience accumulation and surgical technique improvement. |
