To compare the effect of surgical and non-surgical treatment for multiple fractured ribs retrospectively, with 30 cases in each group. Patient's length of stay, visual analogue scale ( VAS) pain, independent ambulation time, cost of hospitalization, thoracoplasty degree and the lung ventilation function were evaluated. The results showed that VAS declined obviously in patients of surgical group, length of stay and independent ambulation time were shorter. Compared to the non-surgical group, the maximal voluntary ventilation increased significantly and ref-erral rib reduction was significantly better, but cost of the surgical group was higher. It's an effective treatment for using nickel titanium memory alloy embracing fixator in the treatment of multiple fractured rips, and is worthy of clinical application.
