Abstract:

BACKGROUND: With the development of internal fixation materials, simple operation with internal fixation has become a tendency. Ni-Ti shape memory alloy embracing fixator has such advantages as slight injury, easy operation, security, reliable fixation, and better histocompatibility. The present study was to explore curative effect and postoperative results of Ti-Ni shape memory alloy embracing fixator in patients with multiple fractured ribs and flail chest.

METHODS: The curative effect and long-term follow-up results were observed after internal fixation with a shape memory alloy embracing fixator in patients with multiple fractured ribs and flail chest from January 2006 to December 2009.

RESULTS: All patients were cured with an average hospital stay of 10.31±3.14 days. Post-operative pain was less severe than preoperative pain (P=0.02).The rate of postoperative complications such as atelectasis, pulmonary infection, etc was 17.65%. There were fewer long-term complications and less influence on daily work and life.

CONCLUSIONS: It is practical to perform an operation for fracture of multiple ribs using a Ti-Ni shape memory alloy embracing fixator. The fixator, which is less traumatic, simple, safe, and reliable, has a good-histocompatibility and fewer postoperative complications.
