手法整复配合超声检查治疗成人移位伸直型桡骨远端骨折OA

Objective:To evaluate whether ultrasound-guided manipulations improve the success rates of closed reduction for distal radius fractures.Methods:Patients who underwent closed reduction for dorsally displaced distal radius fractures between October 2022 and June 2024 were retrospectively reviewed.The ultrasound-guided group was performed under ultrasound guidance.The non-ultrasound-guided group consisted of patients who underwent closed reduction without ima-ging assistance during the procedure.X-ray images of the distal radius were obtained for all patients before and after manipulative reduction.X-ray parameters,Quick DASH scores,and success rates were compared between the ultrasound-guided group and the non-ultrasound-guided group.Results:We reviewed 120 patients:the ultrasound-guided group(group A)consisted of 60 patients,and the non-ultrasound-guided group(group B)also consisted of 60 patients.There were no significant differences between the groups in regard to age,gender,body mass index(BMI),fracture classification,time to presentation,ulnar styloid fracture,and X-ray parameters before reduction(P>0.05).The success reduction rates of the group A and the group B were 91%and 71%,respectively.There was a significant difference in the success rate(P=0.01).Several radiographic measurements were collected immediately after reduction,including dorsal/volar tilt of the ra-dius,radial height,radial inclination,and ulnar variance.Dorsal/volar tilt of the radius and radial inclination were improved in the ultrasound-guided group(9°(-8°,20°)vs 5°(-8°,10°),W=2 740,P<0.01;15°(10°,20°)vs 12°(0°,20°),W=1 316,P=0.01).However,the Quick DASH scores revealed no significant difference between the two groups after 5 months(0(0,6.8)points vs 0(0,9.1)points,W=1 768,P=0.86).Conclusion:Ultrasound-guided closed reduction can aid in the manipul-ative reduction of distal radius fractures.
