南京地区国人股骨头头颈直径比例的影像学测量

目的 通过X线片确定南京地区国人股骨头头颈直径比例的正常值.方法 选择468例无髋部症状的生活在南京及周边地区的成年中国人,男313名,女155名;年龄17～82岁,其中≤20岁13名,21～30岁88名,31～40岁123名,41～50岁104名,51～60岁102名,61～70岁24名,≥71岁14名,平均年龄42.4岁.摄标准骨盆正位X线片,应用Digimizer软件测量左、右侧股骨头最大直径与股骨颈最小纵径,并分别计算比值.将计算结果与西方人数据进行比较.结果 股骨头头颈直径比例1.33～1.69,平均1.48±0.09.≤20岁者1.46±0.09,21～30岁者1.48±0.09,31～40岁者1.47±0.10,41～50岁者1.46±0.09,51～60岁者1.49±0.10,61～70岁者1.48±0.08,≥71岁者1.49±0.10.不同性别、侧别及年龄组间差异均无统计学意义.南京地区国人股骨头头颈直径比例(左侧、右侧分别为1.48±0.09、1.48±0.10)与欧洲人数据(左侧、右侧分别为1.43±0.09、1.44±0.09)比较差异有统计学意义(P值均＜0.05).结论 南京地区国人股骨头头颈直径比例不存在性别、年龄及侧别差异.国人数据与欧洲人不同与种族的解剖差异有关.正常人群的股骨头头颈直径比例可能对某些髋关节疾病的诊断与治疗具有一定的参考意义.

Abstract：

Objective To measure the femoral head-neck ratio among Chinese adults in Nanjing to explore its clinical significance. Methods 468 Chinese without hip symptoms were chosen randomly. There were 313 males and 155 females. 13 cases were less than 20 years old, 88 cases were from 21 to 30 years old, 123 cases were from 31 to 40 years old, 104 cases were from 41 to 50 years old, 102 cases were from 51 to 60 years old, 24 cases were from 61 to 70 years old, 14 cases were more than 71 years old. The mean age was 42.4 years old (ranged from 17 to 82 years old). The maximum diameter of the femoral head and the minimum vertical diameter of femoral neck length on both sides were measured by Digimizer software in the standard anteroposterior pelvis film. The femoral head-neck ratio (FHNR) was calculated and compared with that of the western. Results The normal FHNR of Chinese in Nanjing was 1.48 ± 0.09 (1.33-1.69). FHNR was 1.46±0.09 in Chinese aged less than 20 years old. It was 1.48±0.09 in Chinese aged from 21 to 30 years, and 1.47±0.10 in those aged 31-40 years, 1.46±0.09 in 41-50 years, 1.49±0.10 in 51-60 years,1.48±0.08 in 61-70 years, 1.49±0.10 in those more than 71 years. There was no difference between male and female, the left and right side or the different age groups. There was no difference between the western and Chinese in Nanjing. Conclusion FHNR measurement has not variation with regard to sex, age and side. It may be useful to understand some kind of the hip diseases.
