Abstract

Abstract:

BACKGROUND: Elastic intramedullary nail fixed technology supported by three principle of elastic fixation fracture is suitable for children’s short transverse and oblique shape limbs long tubular bone fracture. This paper will investigate the advantages of elastic intramedullary nail in the treatment of femoral shaft fracture with failed plate fixation in children.
OBJECTIVE: To observe the clinical effect and prognosis of elastic intramedullary nail technology in the treatment of femoral shaft fracture with failed plate fixation in children.
METHODS: Retrospective analysis was performed in 21 cases of femoral shaft fracture patients with plate fracture and failure after fixation in the Department of Pediatric Orthopedics, Gansu Provincial Hospital of Traditional Chinese Medicine from March 2008 to August 2012. During the surgery, the plates were removed from the primary incision; after cleaned the fracture end, the medial and lateral retrograde percutaneous penetration of elastic nail was performed to fix the fracture on 1.0-2.0 cm from the femoral distal patellar. At 3-6 months after surgery, the healing of the fracture was evaluated based on the imaging data, and then the screw was removed. The efficacy was analyzed in accordance with the Flynn fracture healing criteria in 2001.
RESULTS AND CONCLUSION: All the 21 patients were followed-up for 10 months in average. According to the Flynn fracture healing criteria, there were 19 cases of excellent, two cases of good, no poor, and the excellent and good rate was 100%. After followed-up for 10 months, two cases had overgrowth of affected limbs with the unequal length <1.0 cm, and disappeared in 1 year; three cases had limited activity of 30°-50°, and after 1 year functional exercise, two cases had limited activity of <15°, and one case had limited activity of >30°, there was no elastic nail breakage or nonunion. Compared with open reduction technology, elastic intramedullary nail for fracture fixation has fast recovery and healing and has fewer complications, so it is the effective method for the treatment of femoral shaft fracture fixation in children.
