Objective: To evaluate the clinical result of the treatment of old femoral neck fracture and nonunion with free vascularized fibular grafting.
Methods: From November 2000 to December 2005, 29 cases with old femoral neck fracture and nonunion had been treated by free vascularized fibular grafting with an average follow-up of 28.5 months.
Results: All the fracture were healed without any severe complications. And the healing time was 4-6 months (5.6 months on average). During the follow-up, the hips of 28 cases got well-function, and the average Harris hip score was 88.2. One case came about with osteonecrosis of femoral head after one year and finally accepted THA after 2 years.
Conclusions: The free vascularized fibular grafting is a valuable procedure to treat old femoral neck fracture and nonunion.
