【目的】探讨3D打印技术在骨盆髋臼骨折手术治疗中的可行性和临床应用价值。【方法】对6例髋臼骨折患者进行螺旋CT扫描，将其DICOM数据输入计算机中，采用 Mimics软件数据处理。应用3D打印技术打印骨折模型，制定手术方案，于内固定前模拟手术过程。然后实施手术，从手术入路、钢板长度、螺钉数量及长度方面进行对比，同时对实际手术时间进行记录。【结果】6例完全采用了计划固定方法，患者术中采用的固定钢板、螺钉数与螺钉长度均与术前计划一致。随访 X线及 CT显示关节面解剖复位4例，满意复位2例，没有螺钉穿入关节腔。【结论】3D打印技术应用于髋臼骨折的治疗临床可行性良好，有助于术者对髋臼骨折的理解和术前计划的制定。“,”[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.
