[Treatment of old femoral neck and nonunion with free vascularized fibular grafting].

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.
