Effect of adolescent interlocking intramedullary nail on the proximal femur in the treatment of femoral shaft fractures

doi:10.3969/j.issn.2095-4344.0346

Abstract

Abstract:

BACKGROUND: The treatment of femoral shaft fractures in adolescents is under discussion. Femoral shaft fracture treated using adolescent interlocking intramedullary nail is seldom reported.

OBJECTIVE: To observe the proximal femoral changes in adolescent femoral shaft fractures after treated using adolescent interlocking intramedullary nail.

METHODS: Clinical data of 18 patients with femoral shaft fractures undergoing treatment of adolescent interlocking intramedullary nail from February 2014 to August 2016 at Fuzhou Second Hospital, Xiamen University were analyzed retrospectively. The uninjured side was used as control group, and the radiographs at last follow-up were analyzed to assess the incidence of osteonecrosis of the femoral head, valgus deformity of coxa as well as stenosis of femoral neck. The geometric parameters of bilateral proximal femurs were measured by imaging processing software, and then compared between two sides. Additionally, the Nonarthritic Hip Score was used to assess the hip joint function at the last follow-up.

RESULTS AND CONCLUSION: (1) All patients were followed up for 16-46 months. All achieved bony union, and none of osteonecrosis of the femoral head, valgus deformity of coxa or stenosis of femoral neck occurred. (2) There were no significant differences in the geometric parameters of proximal femur and the Nonarthritic Hip Score between injured and uninjured sides (all P > 0.05). (3) Our findings indicate that adolescent interlocking intramedullary nail can achieve satisfactory results in the treatment of femoral shaft fractures without complications.
