Preliminary clinical application of 3D printing technology on treatment of SchatzkerType II and III fractures of tibial plateau
Objective To investigate the application value of 3D printing technology on articular surface reduction of Schatzkertype II and IIIfractures of the tibial plateau. Methods 11 patients of tibial plateau fracture (Schatzkertype II and III) were recruited whose CT data were used for three-dimensional (3D) printing to guide the articular surface reductions (3D printinggroup). As a contrast, 16 patientsof tibial plateau fractures (Schatzkertype II and III) were recruited and were treated by conventional surgical methods (Traditionalgroup). The maximum step height of articular surface after reduction and operation time were recorded and compared using independent-sample T test. Results The average operation time in the 3D printing group was(112.3±6.8)min, which was significantly shorter than that in the traditional group (121.7±12.8 min)(t=2.223，P=0.036). The maximum step height of articular surface in the 3D printing group were (2.8±0.4)mm, which was significantly less than that in the traditional group (3.1±0.5)mm (t=2.123，P=0.044). Conclusion The 3D printing technology could improve the articular surface reduction of tibial plateaufractures(Schatzkertype II and III) and decrease the operation time.
