Study on curative effect of assisted surgical treatment based on 3D printing technology on complex Pilon fractures / 中国基层医药

ABSTRACT

Objective:To explore the curative effect of assisted surgery based on 3D printing technology on complex Pilon fractures.Methods:From June 2017 to June 2018, 52 patients with complex Pilon fracture treated in the General Hospital of Armed Police Navy were selected in the study.The patients were divided into study group ( n=26) and control group ( n=26) according to different operation mode.The control group was treated with traditional open reduction and internal fixation, and the study group was supplemented with 3D printing technology.The differences of treatment effect, operation time, intraoperative hemorrhage, fracture healing time, hospitalization time, incidence of complications, ankle function score and VAS pain score between the two groups were compared. Results:The total effective rate of the study group was 88.5%(23/26), which was higher than 65.4%(17/23) of the control group (χ 2=3.900, P=0.048). The mean operation time ( t=-3.770, P<0.001), mean fracture healing time ( t=-2.206, P=0.032) and mean hospitalization time ( t=-9.542, P<0.001) of the study group were shorter than those of the control group, and the amount of intraoperative bleeding ( t=-20.226, P<0.001) was less than that of the control group, the differences were statistically significant.The total incidence of complications in the study group was 15.4%(4/23), which was lower than 42.3%(11/23) in the control group (χ 2=4.591, P=0.032). With the development of time, the ankle function score of the two groups increased gradually, and the VAS pain score decreased gradually ( P<0.05). One month after operation, the ankle function score of the study group was higher than that of the control group ( t=2.340, P=0.023), but there was no statistically significant difference between the two groups in VAS pain score ( t=-0.278, P=0.782). At the last follow-up, the ankle function score of the study group was higher than that of the control group( t=2.760, P=0.008), and the VAS pain score of the study group was lower than that of the control group( t=-3.633, P<0.001), the differences were statistically significant. Conclusion:3D printing assisted surgery is better than traditional open reduction and internal fixation in the treatment of complex Pilon fracture, with shorter operation time, fracture healing time and hospitalization time, less intraoperative bleeding, lower incidence of complications and better postoperative recovery.
