摘要: 目的:测量国人桡骨小头的形态学参数,并与西方人群桡骨小头形态参数测量值进行比较,为设计出国人桡骨小头假体提供参考。方法:选取国内130人正常肘关节的CT扫描数据,所有数据均使用64层螺旋CT扫描仪进行扫描,并在GEAW 4.5工作站上进行重建和测量。分别测量颈干角(∠α)、桡骨近端颈和头长度(LNH)、桡骨小头最大直径(D1MAX)、桡骨小头最小直径(D2MIN)、桡骨小头凹陷关节面最大直径(D3MAX)及最大垂直凹陷深度(DD3)、最大直径与定义水平面夹角(∠β3)、凹陷关节面最小直径(D4MIN)及最大垂直凹陷深度(DD4)和最小直径与定义水平面间夹角(∠β4),比较男性和女性测量结果的差异并分析不同参数之间的相关性。结果:正常男性∠α、LNH、D1MAX、D2MIN、D3MAX、DD3、D4MIN和DD4大于正常女性(P<0.01)。正常男性∠β3和∠β4测量值以及DD4/D3MAX、D4MIN/D3MAX、∠β3/∠β4和D2MIN/D1MAX比值与正常女性比较差异无统计学意义(P>0.05)。∠α、LNH、D1MAX、D2MIN、D3MAX和D4MIN任意2个参数之间均存在较强的正相关关系(P<0.05),∠β3与∠β4之间也存在较强的正相关关系(P<0.05)。结论:国人男性和女性桡骨小头形态相似,形态学参数与国外人群存在差异。

Abstract: Objective: To measure the morphological parameters of the radial head of the Chinese and compare with those of the Western population, and to provide the references for the design of the radial head prosthesis of the Chinese. Methods: The CT scan data of normal elbow from 130 Chinese cases were selected. All the data were scanned by using a 64-slice spiral CT scanner and reconstructed and measured on AW 4.5 workstations. The angle between neck and shaft (∠α),the proximal radial length of neck and head (LNH), the maximum diameter of radial head (D1MAX), the minimum diameter of radial head (D2MIN), the maximum diameter of articular surface (D3MAX) and the maximum vertical depression depth (DD3),the angle between D3MAX and horizontal plane (∠β3),the minimum diameter of articular surface (D4MIN) and the minimum vertical depression depth (DD4), and the angle between D4MIN and horizontal plane (∠β4) were measured. The measurement results of the male and female were compared and the correlations between different parameters were analyzed. Results: The measured values of ∠α, LNH, D1MAX, D2MIN, D3MAX, DD3, D4MIN and DD4 of the normal male were larger than those of the normal female (P<0.01). There were no significant differences in the measured values of ∠β3 and ∠β4 and the ratios of DD3/D3MAX, D4MIN/D3MAX, ∠β3/∠β4 and D2MIN/D1MAX between the normal male and the normal female (P>0.05). There was a strong positive correlation between ∠α, LNH, D1MAX, D2MIN, D3MAX and D4MIN (P<0.05), and there was also a strong positive correlation between ∠β3 and ∠β4(P<0.05). Conclusion: The morphology of radial head of the normal male Chinese is similar to the female. The morphological parameters of the radial head in the Chinese people are different from those in other countries.
