摘　　要：目的 测量分析成人桡骨头骨性结构并对双侧桡骨头进行立体配准,分析其差异性,并对包括年龄、性别、BMI在内的多种因素的相关性进行初步研究。方法 收集53正常志愿者双肘三维CT数据,22例女性、31例男性,平均年龄(34.2±8.1)岁,除外骨性结构异常。影像学数据以DICOM格式传输到MIMICS 21.0软件中,测量双侧桡骨头外侧缘最大直径(D1_(max))、最小直径(D1_(min))、内侧缘最大直径(D2_(max))、最小直径(D2_(min))、桡骨头高度(H)及曲率半径(r)与颈干角(a);进行双侧桡骨头三维配准,评估双侧桡骨头立体结构差异性;分析年龄、性别及BMI对双侧桡骨头结构差异性的影响。结果 53例患者的左侧D1_(max)、D1_(min)、D2_(max)、D2_(min)、H、r与a分别为(23.13±2.20) mm,(21.76±2.15) mm,(17.68±2.03) mm,(16.62±1.80) mm,(11.13±0.90) mm,(11.61±1.09) mm,(167.78±2.25) mm,(167.78±2.25)°;右侧分别为(23.28±2.12) mm,(21.87±2.15) mm,(18.28±1.83) mm,(16.93±1.77) mm,(11.32±1.33) mm,(11.53±0.89)mm,(167.81±2.31)°。双侧桡骨头在D2_(max)处存在显著差异(P=0.027),但平均差异小于2 mm;其他各解剖学参数双侧对比均无显著性差异(P>0.05)。相关性分析显示年龄、性别、BMI不是结构差异性的影响因素(P>0.05)。结论 正常人群中,双侧桡骨头骨性结构无明显差异,并与年龄、性别、BMI情况无显著相关性,可以将一侧桡骨头骨性结构作为构建对侧桡骨头的解剖模板。Objective To measure bony structure of adult radial head,register three-dimensionally the bilateral radial heads and analyze the correlation of factors including age,gender and BMI.Methods Three-dimensional CT data of both elbows were collected from 53 normal volunteers,consisting of 22 females and 31 males,with an average age of(34.2±8.1)years,excluding those with abnormal bony structures.The radiological data were transferred to the MIMICS 21.0 software in DICOM format.The measurements included the maximum diameter(D1_(max))and the minimum diameter(D1_(min))of the lateral edge of the bilateral radial heads,the maximum diameter(D2_(max))and the minimum diameter(D2_(min))of the medial edge,the height of the radial head(H),the radius of curvature(r),and the neck-shaft angle(a).Further,three-dimensional registration of bilateral radial heads was conducted to evaluate the differences in the stereo structure of both sides.The effects of age,sex and BMI on the structural differences of bilateral radial heads were analyzed.Results For all patients,the left D1_(max),D1_(min),D2_(max),D2_(min),H,r,and a were(23.13±2.20)mm,(21.76±2.15)mm,(17.68±2.03)mm,(16.62±1.80)mm,(11.13±0.9)mm,(11.61±1.09)mm,and(167.78±2.25)°respectively.For the right side,the values were(23.28±2.12)mm,(21.87±2.15)mm,(18.28±1.83)mm,(16.93±1.77)mm,(11.32±1.33)mm,(11.53±0.89)mm,and(167.81±2.31)°respectively.There was significant difference in D2_(max) between the bilateral radial heads(P=0.027),but the average difference was less than 2 mm and not clinically significant.There were no significant differences in other anatomical parameters between both sides.Correlation analysis showed that age,gender and BMI were not the influencing factors of structural differences.Conclusions In the normal population,there are no significant differences in the osseous structure of the bilateral radial heads,and no significant correlation among age,gender or BMI.Therefore,the osseous structure of one radial head can be used to construct an anatomical te
