Abstract

Abstract:

BACKGROUND: The limitation of the traditional intramedullary nailing relies on the personal experience of the doctor. Moreover, the enlargement of the bone marrow causes the destruction of the biological environment of the marrow cavity and affects the healing of bone.
OBJECTIVE: To observe therapeutic effect of digital technology assisted intramedullary nail fixation for femoral shaft fracture.
METHODS: A total of 80 patients with femoral shaft fracture, who were treated in the Department of Orthopedics, Affiliated Hospital of Putian University from January 2010 to January 2014, were enrolled. Digital technology was used to assist treatment. Three-dimensional digital model of femoral shaft fracture was established before treatment. Virtual reduction was conducted in the three-dimensional digital fractures. The diameter of medullary cavity was measured. Appropriate specification of intramedullary nailing was selected according to the measurement data. Closed reduction and intramedullary nailing were performed according to operation scheme
of digital technology.
RESULTS AND CONCLUSION: The 80 patients were followed up for 12 to 24 months. Fractures were completely healed. At 12 months after treatment, they were evaluated by clinical curative effect standard in department of orthopedics. There were excellent in 62 cases, good in 15 cases, and good in 3 cases, with the excellent and good rate of 96%. No complications occurred such as infection, fixator breakage or loosening. These results verify that digital technology assisted intramedullary nail fixation for femoral shaft fracture obtained positive therapeutic effects, could obviously shorten operation time, reduce surgical trauma, and diminish intraoperative X-ray emission to patients and health care workers.
