Insert Nails When Flexing the Knee in the Femoral Fracture External Fixation: A Technical Report

Abstract

Background: The application of external femoral fixation techniques often causes complications of knee flexion dysfunction. We report on technical modifications in the complications of external femoral fixation leading to knee flexion disorders.Methods: We flexed the knee joint 90 degrees during the operation, and then placed the external fixation nail. A retrospective review was performed for all patients undergoing repair by this technique. Results: A total of 52 children with femoral shaft fractures were included, the flexion of the knee joint measured at the time of discharge was 80 degrees (70-90 degrees) on average; when the external fixation is removed, the knee flexion can reach an average of 95 degrees (90-115 degrees), no children have stiff knees.Conclusion: This technique is simple and easy to implement, and it is worthy of popularization and application in clinical practice.
