Description
技术领域technical field
本发明涉及一种股骨干横断骨折侧翼型接骨板，属于接骨板技术领域。The invention relates to a lateral wing bone plate for femoral shaft transverse fracture, belonging to the technical field of bone plates.
背景技术Background technique
由于在骨折部位施加压力有助于愈合的理论出现，逐渐发展出了动力加压接骨板(DCP)。为了克服接骨板去除后产生二次骨折和骨与接骨板之间的接触导致骨皮质坏死等缺陷，在DCP基础上发明了一个减少了骨板间接触面积和骨皮质血运受损的接骨板，称为有限接触动力加压接骨板(LC-DCP)。Perren研究小组针对上述问题进一步改进接骨板设计出了点式接触内固定(PC-Fix)系统。人们在保留传统LC-DCP和PC-Fix各自的优点的基础上，运用螺纹偏心加压原理，设计出了锁定加压接骨板(LCP)。李起鸿等在普通接骨板的底面焊接锥状突起，研制了一种锥状点式接触钢板。赵玉峰等设计的复合动力点接触接骨板经过生物力学测试，显示的弯扭强度与DCP板基本相似。许多医学工作者在我国传统医学的基础上，结合国外动力加压接骨板的优点设计出包括槽状带齿自动加压钢板、非等强度自动加压钢板、梯型自动加压钢板等接骨板系统。The Dynamic Compression Plate (DCP) was developed as a result of the theory that applying pressure to the fracture site aids in healing. In order to overcome defects such as secondary fractures after bone plate removal and cortical bone necrosis caused by contact between bone and bone plate, a bone plate with reduced contact area between bone plates and impaired blood supply of bone cortex was invented on the basis of DCP. , called the Limited Contact Dynamic Compression Plate (LC-DCP). Perren's research group further improved the bone plate and designed a point contact internal fixation (PC-Fix) system to address the above problems. On the basis of retaining the respective advantages of traditional LC-DCP and PC-Fix, people have designed the Locking Compression Plate (LCP) by using the principle of thread eccentric compression. Li Qihong et al. welded conical protrusions on the bottom surface of ordinary bone plates, and developed a conical point contact plate. The composite dynamic point contact osteosynthesis plate designed by Zhao Yufeng et al. has undergone biomechanical tests, showing that the bending and torsional strength is basically similar to that of the DCP plate. On the basis of traditional medicine in my country, many medical workers have designed bone bone plates including grooved toothed automatic compression plates, non-equal strength automatic compression plates, and trapezoidal automatic compression plates, etc. system.

步骤五、四个侧翼临时螺钉置入后，依次取出临时螺钉，电钻重新扩孔后植入四枚锁定螺钉；Step 5. After the four flank temporary screws are placed, take out the temporary screws one by one, re-open the hole with an electric drill, and implant four locking screws;
步骤六、完成接骨板植入并完成螺钉固定后，缝合手术切口，完成操作。Step 6: After the bone plate implantation and screw fixation are completed, the surgical incision is sutured to complete the operation.
以上即完成股骨干横断骨折侧翼型接骨板的完整植入过程。The complete implantation process of the lateral wing-shaped bone plate for the transverse fracture of the femoral shaft is completed above.
