A morphometric study of the proximal radius was performed with computed tomography scanning in 51 healthy adults. These dimensions were then compared with those of a commercially available floating radial head prosthesis. Results were expressed as mean values, SD, and minimum and maximum values. The minimum and maximum diameters of the radial head were 21.9 +/- 1.9 mm and 22.9 +/- 1.9 mm, respectively. The minimum and maximum intramedullary diameters of the radial neck were 8.3 +/- 1.3 mm and 9.3 +/- 1.5 mm, respectively. The combined length of the radial head and neck was 22.47 +/- 2.84 mm. The implications for prosthetic design are as follows: the small floating cup (19 mm in diameter) is too small for the large majority of adults, the large floating cup (22 mm in diameter) is closer to the radial anatomy, the mean values are significantly different between male and female patients, and a single component would suffice for right and left elbows.
对51名健康成年人进行了近端桡骨的形态测量研究，采用计算机断层扫描。然后将这些尺寸与市售的浮动桡骨头假体的尺寸进行比较。结果以平均值、标准差以及最小值和最大值表示。桡骨头的最小和最大直径分别为21.9±1.9毫米和22.9±1.9毫米。桡骨颈的最小和最大髓内直径分别为8.3±1.3毫米和9.3±1.5毫米。桡骨头和颈的总长度为22.47±2.84毫米。对假体设计的影响如下：小浮动杯（直径19毫米）对大多数成年人来说太小，大浮动杯（直径22毫米）更接近桡骨解剖结构，男性和女性患者的平均值有显著差异，并且左右肘部使用单个组件就足够了。
