Biomechanical assessment showed that the three dimensional plate developed by the authors which had stereo-rigidity in the fixation of long bone fractures was superior to compressive plate and flanged plate in terms of anti-compressive and anti-torsional strength. The anti-bending strength was superior to the flanged plate but inferior to compressive plate. The comprehensive nature of the three dimensional plate remained superior. Clinical application in 112 cases with 85 of them being followed-up for 8-44 months showed that bone union occurred in 45-98 days. The average was 82 days. In 65 cases of them the plates had been removed. No delayed-union or non-union occurred. Preliminary experience showed that the three dimensional plate was a new design for the treatment of long bone fractures. It can be applied to various types of long bone fractures especially the severe comminuted fractures owing to its requirement of proper fixation.
生物力学评估表明，作者研制的三维接骨板在长骨骨折固定中具有立体刚性，在抗压和抗扭强度方面优于加压接骨板和带翼接骨板。抗弯强度优于带翼接骨板，但低于加压接骨板。三维接骨板的综合性能仍更优。对112例患者的临床应用（其中85例随访8 - 44个月）显示，骨愈合发生在45 - 98天，平均为82天。其中65例已取出接骨板，未发生延迟愈合或不愈合。初步经验表明，三维接骨板是治疗长骨骨折的一种新设计。由于其对固定的适当要求，它可应用于各种类型的长骨骨折，尤其是严重粉碎性骨折。
