本文介绍了一种利用髓内钉监测股骨骨合成后骨折愈合进展的系统。固定的钉子使外科医生能够在体内对骨/种植体系统进行刚度测量。过去已经开发了各种技术来测量骨痂的硬度，但很少有研究对指甲治疗骨折进行研究。该系统由一个被动测量模块组成，该模块位于钉子内部。电源和数据通过无源模块和位于身体外部的读取器单元之间的低频感应链路无线传输。植入物的导电材料和植入物与读取器之间的距离使得该遥测系统的设计雄心勃勃。
This contribution presents a system designed to monitor the fracture healing progress after osteosynthesis of the femoral bone, using an intramedullary nail. The instrumented nail enables the surgeon to perform stiffness measurements of the bone/implant system in vivo. Various techniques have been developed in the past to measure the stiffness of the callus, but little research has been done on fractures treated with nails. The presented system consists of a passive measuring module, which is located inside the nail. Power and data are transmitted wirelessly by a low-frequent inductive link between the passive module and a reader unit located outside the body. The conductive material of the implant and the distance between implant and reader unit make the design of this telemetric system ambitious.
