摘要
解剖钢板的螺孔为椭圆形,螺孔纵轴与接骨板纵轴一致或平行。钢板的板螺孔周边为光滑平面,与长骨纵轴相平行或一致,在有外力或内力情况下,螺钉顶端可在螺孔周边的光滑面上产生相对移动,这种移动是"可逆"的。国产解剖钢板能稳定的固定骨折,同时,在外力或内力作用下,骨折断端之间能产生"微动",刺激骨折断端并产生初始骨痂反应,反复力的作用将有利于重复产生初始骨痂反应,保护脆弱的新生血管和骨小梁不受破坏,有效促进骨折愈合。
The screw holes of anatomic plate are oval, and longitudinal axis of the screw hole is parallel to the axis of the plate. The plate surrounding the screw hole is smooth, parallel to the longitudinal axis of the long bone. Under outside force or inside force, the top of screw can move on the smooth surface surrounding the screw hole; the movement is a reversible one. Domestic plate can fix bone fracture stably, and the outside force and inside force can result in micromovement of the fracture ends, stimulating the fracture ends and bone callus formation. Repetitive force is beneficial to bone callus response, protect fragile new vessels and bone trabecula from damage, and promote fracture healing.
