Impact of Transverse Ultrasound Images on the Classification and Treatment of Pediatric Lateral Humeral Condyle Fractures.

Background: Pediatric lateral humeral condyle fractures (LHCFs) are sometimes misdiagnosed and inappropriately treated on the basis of x-ray radiographs because cartilage cannot be seen on radiographs. However, as a useful technique, transverse ultrasonography can accurately and readily determine the integrity of the cartilage hinge in pediatric LHCFs. The purpose of this study was to assess the reliability of the Jakob classification, the treatment plan, and the necessity for further examination of pediatric LHCFs with the use of x-ray with and without transverse ultrasound images.
