Abstract
Purpose
This study aimed to evaluate the feasibility of reduction under ultrasonographic (US) guidance with Kirschner wires (K-wires) and fixation with elastic stable intramedullary nails (ESINs) in the treatment of radial neck fractures (RNFs).
Methods
This retrospective study included 50 children treated for Judet types III and IV RNFs at our hospital from September 2015 to November 2018. Patients were divided into two groups: group A (without US) and group B (with US). Group A patients were treated using the Métaizeau technique; one K-wire was used for reduction under the guidance of X-ray fluoroscopy. Group B patients were treated using the same technique, but under the guidance of US. Post-operative radiographs, elbow function, and complications were analyzed.
Results
All patients were followed up over a period of 12 months. Five patients in group A had posterior interosseous nerve (PIN) injury, whereas no patient in group B had PIN injury (p = 0.016). The use of US guidance resulted in lower radiation exposure and shorter operation time. According to the Mayo Elbow Performance Index, there was no significant difference between the two groups (p = 0.814), including post-operative complications (radial head necrosis, fracture displacement, or stiffness).
Conclusion
US guidance during surgery is feasible to treat Judet type III and IV RNFs. US guidance can significantly reduce X-ray radiation exposure and the risk of PIN injury.
