Abstract: Femoral shaft fracture is a common and frequently occurring disease in clinic. The treatment methods of femoral shaft fracture in children include conservative treatment and surgical treatment. During treatment, it is required to give strong fixation to the broken end of the fracture to ensure good alignment and alignment, so as to achieve fracture healing on schedule and avoid complications. If treatment method and internal fixation are selected incorrectly, there will be delayed fracture healing, nonunion and even residual deformity, which will bring disastrous harm to patients and families. Based on the experience of a child with femoral shaft fracture after six operations, this paper analyzes the whole treatment process, finds out the errors and deficiencies in the treatment process, summarizes the lessons of failure, and rings an alarm for later clinicians in the treatment of children with femoral shaft fracture.

Key words: femoral shaft fracture in children, treatment, causes of deformity, countermeasures
