摘要
目的 比较腓骨头与桡骨腕关节面形态,为用腓骨头移植替代桡骨远端重建腕关节手术提供理论依据。方法 对40个成人尸体腕关节和腓骨头标本,用三维摄影测量的方法将腓骨头和桡骨腕关节面实物模型转换成数字模型,利用数字模型计算各关节面的曲率、弧长和倾角,并进行比较。结果桡骨腕关节面和腓骨头两关节面内倾角分别为23.07°±2.14°、22.58°±1.97°,前后倾角分别为10.58°±1.75°、9.97°±1.47°。两关节面在冠状面的曲率分别为0.158±0. 028、0.154±0.021,在矢状面曲率分别为0.134±0.023、0.136±0.019,两关节面在冠状面的弧长分别为(30.28±1.27)mm、(15. 9± 1. 90) mm,在矢状面的弧长分别为(15. 9±1. 21) mm、(12. 8±1. 30) mm。两关节面的曲率、倾角差异无显著性意义,但两关节面的弧长差异有非常显著性意义。结论用腓骨头替代桡骨远端重建腕关节是合适的,其替代的最佳部位位于桡骨茎突内侧(10.43± 0. 86) mm。
To compare the shape the carpal articular surface of radius with that of the capitulum fibulae to provide the basis for reconstruction of wrist joint with the caput of fibula. Methods The carpal articular surface of the radius and the caput of the fibula in 40 adults cadaver specimens were measured with three-dimension photogrametry. The practical model was thus formed into digital model, and the curvature, arc length and inclination angle of all articular surface of the radius were calculated and compared with the fibula. Results The ulnar inclination angle of the radius and fibular was 23. 07°± 2. 14°, 22. 58°± 1. 97°, the volar inclination was 10. 58°± 1. 75°, 9. 97°±1. 47°, the curvature in coronary section was 0. 158 ±0. 028, 0. 154 ±0. 021 and 0. 134 ±0. 023, 0. 136 ±0. 019 in sagittal section. The arc length of the joint surface in coronary section were (30. 28±1. 27) mm, (15. 9 ±1. 90) mm and (15. 9 ± 1. 21 ) mm, (12. 8 ± 1. 30) mm in the sagittal section. There was no notable distinction between the oblique articular surface and the curvature, but there was marked distinction in arc length. Conclusion The most appropriate place for replacement of the radius with the fibula locate at the inner (10. 43 ± 0. 86) mm of styloideus of the radius.
