Abstract [Objective]To explore the feasibility and clinical value of three-dimension(3D)printing tech-nology in the treatment of acetabular fracture.[Methods]Spiral CT scan was performed in 6 patients with ace-tabular fracture.DICOM data were imported into Mimics software.The 3D printing technology was used to print the fracture models.Operative planning was worked out,and the surgical process was simulated before internal fixation,and then the operation was implemented.The aspects including operation approach,plate length,screw count and length were compared.Meanwhile,the actual operation time was recorded.[Results]The planned fixation method was completely used in 6 patients.The number and length of fixation plate and screw in 5 patients were concurrent with those before operation.The follow-up CT showed that 4 patients (66.7%)achieved anatomic reduction of articular surface,and 2 patients achieved satisfactory results without screw penetration into articular cavity.[Conclusion]The 3D printing technology for the treatment of acetabular fracture is feasible and of clinical significance.It is useful for surgeons to learn about acetabular facture and may be a powerful tool to work out preoperative planning.
