Abstract:
Objective To compare the clinical evaluative value of ultrasound and X-ray in the healing of clavicle fractures in children.Methods A total of 52 pediatric patients with closed complete clavicle fractures were selected.Dynamic monitoring was conducted three times using both ultrasound and X-ray examination after the fracture was confirmed.Ultrasound examination was performed after each X-ray examination.Ultrasound was used to conduct multi-sectional exploration and record the fracture conditions(such as angulation and displacement of the fracture ends),and surrounding soft tissue injuries(such as muscle soft tissue tears or swelling,and hematoma formation).The time of first callus appearance,and the morphology of the callus(including primarily the length,thickness and echo changes of the callus)were recorded and compared with X-ray findings.Results Fifty-two cases(100％)with X-ray plain film showed interruption of the cortical bone continuity,50 cases(96.2％)with ultrasound images showed interrupted and discontinuous of the cortical bone echo,while 2 cases(3.8％)were not definitively diagnosed as fractures.On the 7th day after the fracture,ultrasound detected callus formation in 10 patients(19.2％),while X-ray detected callus formation in 3 patients(5.8％),with a statistically significant difference(P＜0.05).On the 14th day after the fracture,ultrasound detected callus formation in 35 patients(67.3％),while X-ray detected callus formation in 25 patients(48.1％),with a statistically significant difference(P＜0.05).On the 3 5 th day after the fracture,ultrasound detected callus formation in 45 patients(86.5％),and X-ray detected callus formation in 47 patients(90.4％),with no statistically significant difference(P＞0.05).There was no statistically significant difference between ultrasound and X-ray in measuring the length and thickness of the callus(P＞0.05).Conclusion Musculoskeletal ultrasound examination can be used as a potential auxiliary method to evaluate fracture healing in children.
