OBJECTIVE
The objective was to determine if there is a significant difference between rates of non-union of type II and III odontoid fractures in patients with calcium pyrophosphate dihydrate deposition (CPPD) compared with a control population.
MATERIALS AND METHODS
A 10-year retrospective picture archive and communications system review was performed of 31 CPPD patients and 31 control patients. Imaging studies were reviewed for radiographic or CT evidence of osseous union and complications.
RESULTS
There was a significant difference in the rates of non-union between the two groups, with the non-union rate reaching 90.3% in the CPPD group and 32% in the control group. Comparing the degree of displacement and angulation of the two groups did not show a significant difference.
CONCLUSION
The results indicate that odontoid fracture non-union rates are significantly higher in CPPD patients and should be taken into consideration when diagnosing odontoid fractures and deciding on appropriate treatment.
目的
确定与对照组相比，患有二水焦磷酸钙沉积（CPPD）的患者中II型和III型齿状突骨折不愈合率是否存在显著差异。
材料与方法
对31例CPPD患者和31例对照患者进行了为期10年的回顾性影像存档与通信系统审查。对影像学研究进行审查，以寻找骨愈合及并发症的X线或CT证据。
结果
两组的不愈合率存在显著差异，CPPD组的不愈合率达到90.3%，而对照组为32%。比较两组的移位程度和角度未显示出显著差异。
结论
结果表明，CPPD患者的齿状突骨折不愈合率显著更高，在诊断齿状突骨折和决定适当治疗时应予以考虑。
