摘要
Abstract
Objective To explore a new type of fracture reduction and fixation system and to find a new treatment method for clinical fracture reduction and fixation.Methods A new type of adjustable locking reduction fixation system for long bone fractures was developed by analyzing the concept of existing fracture fixation techniques and various clinical fracture types.Taking the locking structure of the locking plate as a prototype,the fixing system was divided into two parts.Combining the existing fixing technology concept and mechanical principle,the connecting rod had the function of adjusting the length.The fracture end was reduced by lifting nail,combined with clinical fluoroscopy assisted fracture line alignment.Full-length X-rays of partial normal adult limbs of the Suzhou Hospital of Medical College,Nanjing University,from January 2019 to July 2022 were selected to measure the length between their bony markers,which was used as the length reference for this design.The data were measured by the ruler of the imaging system.Results The reduction fixation system could treat long bone fracture from a new perspective.During surgery,the surface bony mark was used as the fixation point.The percutaneous septum of the lifting nail was used to reduce the fracture:The length of the fracture end was adjusted by the main nut,and the reduction rack could reduce the fracture,thus realizing the design method of three-dimensional reduction and fixation of the fractures.Conclusion The adjustable locking reduction fixation system had the advantages of convenient operation such as minimally invasive fixation and one-time operation to fix long bone fractures.There was no need for a second operation after bone healing.关键词
