摘要：

目的  探讨影像学参数枕颈角（OC2A）和后枕颈角（POCA）在性别、年龄之间变化规律及相关性，为枕颈融合术中固定头颈位置的角度提供参考。  方法  收集473例（男性339例、女性134例）影像学资料，以性别分2组，每组又以年龄分为≤29岁、30～39岁、40～49岁、50～59岁、60～69岁和≥70岁各6组。将扫描的颈椎断层影像原始数据以DICOM格式存贮，并导入Mimics16.0软件中测量OC2A与POCA，对两者值随性别、年龄的变化行统计学分析。  结果  OC2A和POCA在性别间差异无显著性（P>0.05）。OC2A男性组中30~39岁除与≤29岁男性组外，其余组间差异均存在显著性（P<0.05），而女性组各年龄组间差异均无显著性（P>0.05）； POCA男性30～39岁组中除与≤29岁以下组外，与其余组间差异显著（P<0.05），而40～49岁组则与每组间差异均存在显著性（P<0.05），女性组中则≤29岁组与各年龄组间差异存在显著性（P<0.05），其余各组间差异不显著（P>0.05）；Pearson相关分析显示，OC2A与POCA即两者间不存在相关性 (r=0.038，P>0.05)。  结论  OC2A和POCA值在性别间无差异；男性OC2A和POCA值各年龄段间存在差异，提示临床注意考虑男性年龄差异；而女性OC2A值各年龄段间无差异，POCA却在各年龄段间有差异，OC2A和POCA值在不同年龄段和性别间的变化规律，为枕颈融合术中固定头颈解剖复位角度提供参数依据。

Abstract:

Objective  To explore the differences and correlation of imaging parameters of occipital-C2 angle (OC2A) and posterior occipitocervical angle (POCA) between sex and age, so as to provide theoretical reference for fixing the position of head and neck in occipitocervical fusion.   Methods  The imaging data of 473 cases (339 males and 134 females) were collected and divided into 2 groups according to sex. Each group was subdivided into 6 groups according to age: ≤29 year-old, 30-39 year-old, 40-49 year-old, 50-59 year-old, 60-69 year-old and ≥70 year-old. OC2A and POCA were measured in Mimics software, and their differences with sex and age were statistically analyzed.   Results  There was no significant difference in OC2A and POCA between sexes (P>0.05). In the OC2A male group, except for the male group aged 30-39 year-old and ≤29 year-old, there were significant differences among the other groups (P<0.05), but there was no significant difference among all age groups in the female group (P>0.05); There were significant differences in POCA between the male group of 30-39 year-old and ≤29 year-old (P<0.05), but between the group of 40-49 year-old and each group (P<0.05). In the female group, there was significant difference between the group of ≤29 year-old and all age groups(P<0.05), but there was no significant difference among the other groups (P>0.05). Pearson correlation analysis showed that there was a positive correlation between OC2A and POCA (r=0.038, P>0.05), that is, there was no correlation between them.   ConclusionThere is no difference in OC2A and POCA values between sexes; there are differences in OC2A and POCA values in males among different age groups, suggesting that clinical attention should be paid to the age differences in males, while there is no difference in OC2A values in females, but POCA is different in different age groups. The changes of OC2A and POCA values in different age groups and sex provide a parameter basis for fixing the anatomical reduction angle of head and neck in occipitocervical fusion.
