Surveillance ultrasonography for conservative treatment of femoral shaft fractures in young children.

BACKGROUND

The treatment for femoral shaft fracture (FSF) depends on the age of the patient. While the Pavlik harness is the first choice for patients under 6 months of age, spica casting is preferred for patients over 6 months and under preschool age. Minimally-invasive surgery using elastic stable intramedullary nails is also used in some cases. Skin traction is another treatment choice for some patients who are not candidates for the above methods. This study aimed to evaluate the feasibility of surveillance ultrasonography (US) for the conservative treatment of FSFs in young children.

MATERIALS AND

METHODS

This retrospective study included 92 children who were diagnosed with FSF in our hospital from April 2017 to May 2019. After applying the inclusion and exclusion criteria, they were divided into US surveillance (A) and control (B) groups. All patients received conservative treatment by skin traction. For group A, US was used to assess the femur fractures and adjust its reduction on days 1, 3, 5, 7, 10, and 14 until the fracture stabilized. For group B, the fractures were checked by radiographs on days 1, 3, 5, 7, 10, and 14 until the callus appeared. The FSF angle was measured using anteroposterior and lateral radiographs.

RESULTS

All patients were followed up for 18 months. The radiographic evaluation of both groups at the final follow-up showed a significant difference in the FSF angle. The radiograph times and accumulated radiation also showed significant differences between the two groups. However, there was no significant difference in the incidence of complications.

CONCLUSIONS

For FSF closed reduction, surveillance US is a better option compared to radiographs in children treated by skin traction. This approach can significantly decrease exposure to X-ray radiation and improve the reduction.
