【摘要】：目的通過形態(tài)學(xué)測量方法評估成人橈骨遠(yuǎn)端解剖的對稱性。方法采集15例正常志愿者的雙側(cè)前臂薄層CT掃描數(shù)據(jù),對橈骨遠(yuǎn)端1/3的骨性結(jié)構(gòu)進(jìn)行三維重建,以模型體積和表面積作為目標(biāo)參數(shù)對每一例志愿者左、右側(cè)橈骨的三維模型進(jìn)行解剖測量;進(jìn)一步通過3D偏差分析方法完成雙側(cè)橈骨模型解剖對稱性的定量化和可視化分析。結(jié)果左、右側(cè)橈骨遠(yuǎn)端表面積最大差異小于5.6%(P=0.004),體積差異小于9.1%(P=0.005);3D偏差分析結(jié)果顯示,受試者的最大平均負(fù)偏差為-0.40 mm,最大平均正偏差為0.34 mm;3D偏差較大的區(qū)域主要分布在橈骨遠(yuǎn)端的非關(guān)節(jié)面部位。結(jié)論成人橈骨遠(yuǎn)端在關(guān)節(jié)面形態(tài)方面具有高度的解剖對稱性,臨床上對于橈骨遠(yuǎn)端關(guān)節(jié)內(nèi)骨折的外科解剖重建,采用健側(cè)橈骨鏡像模型作為參考對象有利于指導(dǎo)橈骨遠(yuǎn)端骨折的精準(zhǔn)復(fù)位重建,這對于術(shù)后橈腕關(guān)節(jié)功能的恢復(fù)具有重要意義。
[Abstract]:Objective to evaluate the symmetry of distal radius anatomy in adults by morphological measurement. Methods the bilateral forearm thin slice CT scanning data of 15 normal volunteers were collected and the bone structure of the distal radius was reconstructed by 3D reconstruction. The volume and surface area of the model were used as the target parameters for the left of each volunteer. The 3D model of the right radius was measured, and the quantitative and visual analysis of the anatomical symmetry of the bilateral radial model was carried out by the method of 3D deviation analysis. Results the maximum surface area difference between the left and right radius was less than 5.6, and the volume difference was less than 9.1, the results of 3D deviation analysis showed that the surface area of the distal radius was less than 5.6%, and the volume difference was less than 9.1%. The maximum average negative deviation was -0.40 mm and the maximum average positive deviation was 0.34 mm. The area with large 3D deviation was mainly located in the non-articular surface of the distal radius. Conclusion the shape of the articular surface of the distal radius in adults has a high degree of anatomical symmetry, and the surgical anatomical reconstruction of intra-articular fractures of the distal radius is performed clinically. It is helpful to guide the accurate reduction and reconstruction of distal radius fracture by using the model of normal radial mirror as reference object, which is of great significance for the recovery of radiocarpal joint function after operation.
