Evaluation Of The Efficacy Of Traction In Children With Femoral Fractures By High Frequency Ultrasound

Objective: To explore the application of high frequency ultrasound in traction treatment of femoral fracture and the feasibility of replacing X-ray in children.Methods: Using high frequency ultrasound and X-ray plain film to detect the 62 children who were diagnosed with femoral fracture and are in traction treatment at 1,2,3,4 weeks after the initial fracture occurred.We observed the soft tissue injury around the fracture,the angle and displacement of the fracture.In addition,we also monitor the blood supply around the callus and the size of the callus during fracture healing.The results obtained by ultrasound were compared with X-ray in terms of the time of the first detection of callus and the size of the callus.Results: Ultrasound and X-ray showed statistically significant differences in the time of first indication of callus(p<0.05).There was a statistical difference between the ultrasound and X-ray examination of the size of the epiphysis in the 2nd and 3rd weeks(p<0.05).There was no significant difference in the amount of callus in 4th weeks between ultrasound and X-ray(p>0.05).In addition,ultrasound can early display the damage of soft tissue(such as muscles,blood vessels,etc.)around the fracture site and the growth of the callus,and can dynamically show the fracture line.It can also show the hemodynamic conditions around the callus.Conclusion: As an emerging and non-radiative skeletal system examination method,ultrasound can be used as a monitoring method for fracture healing in children with femoral fracture during the traction treatment because it is simple and easy to implement.It can also be promoted in primary hospitals.
