目的测量分析部分国人肩胛盂的三维解剖结构,为设计适合国人解剖特点的肩胛盂假体提供可靠的解剖数据。方法重庆地区健康成年志愿者90名,男52名,女38名;年龄19～60岁,平均39.6岁。采用CT三维重建、容积再现技术及多平面重组测量双侧盂前后最大径、盂前后曲率半径、盂上下最大径、盂上下曲率半径和盂扭转角。每个参数测量2次,所测结果分别进行左右侧、男女性别比较,分析参数间的相关性。结果90名志愿者盂前后最大径为(2.51±0.32)cm,盂前后曲率半径为(5.50±1.21)cm,盂上下最大径为(3.45±0.29)cm,盂上下曲率半径为(3.98±0.55)cm,盂扭转角为(—0.03±4.66)°。以上参数左右侧间比较,差异均无统计学意义(P>0.05)。盂前后最大径、盂上下最大径、盂上下曲率半径、盂扭转角,男女性之间比较差异均有统计学意义(P<0.05);盂前后曲率半径男女性之间比较差异无统计学意义(P>0.05)。盂前后最大径与对应的前后曲率半径间、盂前后最大径与上下最大径间、盂前后率半径与盂上下曲率半径间均存在相关性(P<0.01),相关系数分别为0.298、0.495及0.262。结论所测肩胛盂参数及其统计学分析结果对国人肩胛盂假体的设计具有一定参考价值。
Objective To measure and analyze the three-dimensional anatomy of the partial glenoid of the Chinese people and provide reliable anatomical data for the design of the glenoid foramen suitable for the anatomy of Chinese people. Methods 90 adult healthy volunteers in Chongqing, 52 males and 38 females; aged 19 to 60 years, mean 39.6 years old. Three dimensional reconstruction of CT, volumetric reconstruction technique and multiplanar reconstruction were used to measure the maximum anteroposterior diameter, the anterior and posterior radius of curvature, the maximum diameter of the glenoid, the curvature radius above and below the glenoid, and the angle of rotation of the glenoid. Each parameter measured 2 times, the measured results were left and right side, gender comparison, analysis of the correlation between parameters. Results The maxillary diameter of the 90 volunteers was (2.51 ± 0.32) cm, the radius of curvature before and after the cellar was (5.50 ± 1.21) cm, the upper and lower maxillary diameter was (3.45 ± 0.29) cm, the upper and lower curvature radius of the cellar was (3.98 ± 0.55) ) cm, and the twist angle was -0.03 ± 4.66 °. The above parameters between the left and right sides, the difference was not statistically significant (P> 0.05). There were significant differences in the maximum diameter before and after the glenoid, the maximum diameter above and below the glenoid, the radius of curvature above and below the glenoid, the torsion angle of the glenoid, and the difference between men and women (P <0.05). There was no significant difference between men and women (P> 0.05). Before and after the glenoid anterior and posterior radius of curvature, anterior and posterior glenoid maximum diameter and up and down the maximum diameter, anterior and posterior glenoid radius and glenoidal curvature radius correlation (P <0.01), the correlation coefficients were 0.298,0.495 and 0.262. Conclusion The measured glenyter glenoid parameters and statistical analysis of the results of the design of the glenoid porcine prosthesis have some reference value.
