[Sonographic diagnostics of proximal humerus fractures in juveniles].

AIM OF THE STUDY

The exact determination of the extent of deformities in juvenile proximal humerus fractures is difficult with plain x-rays. The aim of this study was to find out whether proximal humerus fractures can be diagnosed and the extent of the deformity can be detected by ultrasonography.

PATIENTS AND METHODS

In a prospective, multicentre trial children aged 0-12 years with suspected proximal humerus fractures were examined. Initially a standardized sonographic evaluation was performed and the extent and the direction of the deformity were determined. The recommended treatment was noted. Afterwards standard x-rays were taken and the results of both diagnostic procedures were compared.

RESULTS

A total of 33 children were examined, 14 male and 19 female, with a mean age of 7.6 years. In the ultrasound examination 17 out of 18 proximal humerus fractures were detected. In comparison to x-ray diagnostics ultrasonography proved to have a sensitivity of 94% and a specificity of 100%. In 16 cases ultrasonography gave a better result than x-ray imaging and x-ray was better in 5 cases.

CONCLUSION

Ultrasonography is suitable for detection and exclusion of fractures and better than x-ray diagnosis for evaluation of the type and direction of deformations of proximal humerus fractures.
