Mathematical Analysis of Application of a Three-Dimensional Printing Fixator in the Fracture of Multiple Ribs

Abstract

Data were obtained from 66 clinical patients. The patients were divided into a non-3D printing group (control group) and a 3D printing group (intervention group) in a 1 : 1 ratio, with 33 patients in each group. The information including gender, age, incision length, number of surgical roots, bleeding volume, operation time, and intraoperative blood transfusion was collected for SPSS analysis. The results showed the following: (1) The paired t-test was used to test the difference of experimental data. There was a significant difference of 0.01 between the incision length/surgical root number in the intervention group and the incision length/surgical root number in the control group. The incision length/surgical root number in the intervention group was significantly lower than that in the control group. (2) Surgical time, intraoperative blood transfusion, age, and incision length/surgical root number in the intervention group had a significant positive impact on the amount of bleeding. Gender did not affect the amount of bleeding. (3) A total of 1 item of operation time in the intervention group had a significant positive impact on intraoperative blood transfusion. (4) The incision length/number of surgical roots in the intervention group had a noteworthy negative impact on blood transfusion during the operation.
