Decreased Radiation Exposure Using Ultrasound-Assisted Reduction and Fixation of Femoral Shaft Fractures in Children: A Pilot Study

Abstract

Elastic stable intra-medullary nail procedures have been used to treat femoral fractures in children for some time. Radiation exposure generated by intra-operative radioscopy may induce side effects in children and staff. This study introduces a method of ultrasound-assisted reduction and fixation of femoral fractures in children to decrease radiation exposure. We included 21 children and evaluated displacement of fractures using multi-section scanning. All fracture reductions were performed with ultrasonography. A hyperechoic point with a posterior acoustic shadow can be seen under the proximal and distal segments after the nail passes through the fracture site. Comparison with radioscopy suggests that this is a viable method of reduction and fixation of femoral shaft fractures in children, and can effectively decrease radiation exposure.
