This test indicates that using bicortical screws in the first and third hole of the proximal end of the LISS is the best way for treating distal femur fractures AO/33-A3, it can not only reach the best balance and it create the biggest force to resist torsional force, but also decrease the shearing force, torsional force so as to prevent hardware failure.

采用LISS钢板治疗股骨远端33-A3型骨折时，骨折近端螺钉第1、3孔双皮质固定在钢板、螺钉的固定平衡性及对抗扭转拔出方面明显优于其他各试验组，能够有效地降低钢板、螺钉与骨质之间的剪切力和扭转力，从而防止螺钉、钢板早期松动脱落。

Methods:Animal models of 25 adult mixed breed dogs were established by transverse osteotomy at bilateral iliopectineal crest,which were fixed with ATMFS anterior column connector and steel plate respectively. The animals were examined at 2,4,6,8,and 12 weeks by X-ray,macropathological observation and biomechanical test. Tetracin fluorescent labeling,HE staining,Masson triad colour staining,in situ hybridization and immunohistochemical method were performed and histological image analysis were applied.
