Abstract:
Objective To design and test a device which is capable of accurately measuring and dynamically adjusting the axial pressure at the fracture end in real-time.Methods Upon completion of the design,the pressure measurement and adjustment device was implemented in a canine tibial fracture external fixation model.A pressure sensor was mounted at the fracture end,and the displayed values of the pressure sensor were used as the standard for comparison.The relationship between the displayed values of the measurement and adjustment device and the pressure sensor under identical conditions was examined.Results The device was utilized in external fixation models of tibial fractures in five beagles.A linear correlation was observed between the displayed values of the device and the pressure sensor at the fracture end.The measurement values from the device could be transformed into fracture end pressure through the application of coefficients,thereby facilitating accurate measurement and dynamic adjustment of the fracture end pressure.Conclusion The pressure measurement and adjustment device at the fracture end is easy to operate,enabling precise measurement and dynamic regulation of the pressure at the fracture end.It is well-suited for animal experiments aimed at investigating the impact of axial compression on fracture healing,demonstrating promising potential for experimental applications.
