| 摘要： |
| 目的 探讨单节段Bryan人工椎间盘置换术后异位骨化（heterotopic ossification，HO）形成及其对置换节段活动度（range of motion，ROM）的影响。方法 回顾分析2003年12月~2009年8月期间接受单节段前路减压及Bryan人工椎间盘置换术的患者40例。患者平均随访38.8个月。应用医学影像存储与传输系统观察随访时的HO形成情况并测量手术前后置换节段ROM。利用独立样本t检验分析HO形成与否以及不同HO分级与置换节段ROM间的关系。结果 本组研究中单节段Bryan人工椎间盘置换术后HO的发生率为37.5%，对发生HO的患者采用McAfee分级：Ⅰ级2例，Ⅱ级3例，Ⅲ级8例，Ⅳ级2例。所有患者术前颈椎ROM平均为8.82°，随访时为8.52°。其中未发生HO的患者随访时ROM平均为9.77°，发生HO的患者随访时ROM平均为6.43°，差异有统计学意义（P<0.05）。Ⅰ级和Ⅱ级的HO患者随访时ROM平均为8.76°，Ⅲ级和Ⅳ级的患者为5.26°，差异有统计学意义（P<0.05）。结论 Bryan人工椎间盘置换术后形成HO会导致置换节段ROM的减少，McAfee分级Ⅲ、Ⅳ级的HO患者较之Ⅰ、Ⅱ级更加明显。 |

| Abstract: |
| Objective To evaluate the formation of heterotopic ossification (HO) after Bryan artificial cervical disc replacement and its effect on the postoperative segmental range of motion (ROM). Methods A total of 40 patients undergoing single segment anterior decompression and Bryan disc replacement from December 2003 to August 2009 were reviewed retrospectively. There were 18 males and 22 females, with a mean age of 42.6 years (ranging 20-54 years). All cases were followed up for more than 1 year (ranging 12-69 months, mean 38.8 months). The occurrence of HO was defined by the McAfee's classification, and segmental ROM was measured in picture archiving and communication system (PACS). Independent sample t-test was used to investigate whether the occurrence and grading of HO had a correlation with the segmental ROMs. Results The occurrence rate of HO after single segment replacement was 37.5% (15/40) in this study, and the classification of HO by McAfee's criteria distributed as follows: grade Ⅰ 2 cases, grade Ⅱ 3 cases, grade Ⅲ 8 cases, and grade Ⅳ 2 cases. For all the patients, the mean segmental ROM was 8.82° before operation and maintained at 8.52° at the final follow-up. The mean ROM of the patients with and without HO at the final follow-up were 6.43° and 9.77°, respectively, and the difference with statistical significance was found between them (P<0.05). The mean ROM of HO patients at McAfee grade Ⅰ and Ⅱ was 8.76°, that of those at grade Ⅲ and Ⅳ was 5.26° at the final follow-up, and the difference was statistically significant (P<0.05).Conclusion HO after single segment Bryan disc replacement reduces postoperative segmental ROM, especially for the McAfee grade Ⅲ and Ⅳ. |
