Abstract

Background: Femoral neck fractures in young patients are mostly caused by high-energy trauma and demonstrate more displacement and vertical fracture surfaces, which increase nonunion and osteonecrosis risks. Free vascularized fibula graft (FVFG) is effective in treating old femoral neck fractures and nonunion; however, available data are limited to patients within 2 years after injury or revision surgery. We present the case of a patient who was diagnosed with femoral neck fracture at the age 9 and treated with FVFG 13 years later.

Case Presentation: A 9-year-old Asian girl who experienced left hip pain after an injury was diagnosed with Garden IV left femoral neck fracture, which was treated through manipulation reduction and fixed with splints. At age 16, the pain worsened after another injury and was considered to be in the physical development stage. She refused surgical treatment; hence, the fracture was fixed externally with splints. At age 22, she was hospitalized owing to a 12-day left hip pain with restricted movement caused by a fall. She was diagnosed with old Garden IV femoral neck fracture nonunion and treated with FVFG. Seven years postoperatively, imaging showed that the left femoral neck was internally fixed, the fracture had healed, and the Harris score was 90 points. The 36-Item Short Form Health Survey responses revealed that the patient's physiological functioning, emotional well-being, energy, and mental health were normal. She achieved satisfactory functional results and resumed her normal daily life.

Conclusion: FVFG could provide satisfactory outcomes for long-term old femoral neck fractures.
