Abstract
ObjectiveTo explore the application of 3D printing technology in the treatment of posterior Pilon fracture.
MethodsFrom January 2016 to December 2017, 20 patients with posterior Pilon fracture, including 16 males and 4 females, with an average age of 43.8 years, were randomly divided into experimental group (12 cases) and control group (8 cases). All patients underwent ankle CT plain scan + two-dimensional + three-dimensional reconstruction before operation. 12 patients in experimental group used 3D printing technology to prepare fracture model After the model was established, the precise operation strategy was made, and the operation was performed when the operation time was right. The control group was planned and operated according to the X-ray, CT and other related examination results. The operation time, bleeding volume, postoperative complication rate and ankle function recovery of the two groups were analyzed and compared.
ResultsThere was no significant difference in sex, age, cause of injury and fracture classification between the two groups (t=21.350, P>0.05). The operative time and intraoperative bleeding volume of the experimental group were (64±12) min, (72±8) ml, respectively; the operative time and intraoperative bleeding volume of the observation group were (105±21) min, (132±14) ml, respectively; the operative time and intraoperative bleeding volume of the two groups were statistically significant (t=11.270, 14.320, P<0.05). In the experimental group, the scores of postoperative functional effects were 43±13, 46±10 and 90±8 respectively; in the observation group, the scores of postoperative functional effects were 22±9, 24±7 and 76±7 respectively Academic significance (t=17.230, 21.260, 19.320, P<0.05).
ConclusionWith the help of 3D printing technology before operation, according to the type of fracture, the treatment of posterior Pilon fracture via the posterior medial or posterolateral approach can significantly reduce the operation time and the amount of bleeding, improve the quality of reduction and fixation, the functional recovery of ankle joint, and reduce the adhesion of flexor longus and surrounding the soft tissue. 3D printing technology is conducive to the individualization and accuracy of the treatment plan, with good effect.
