Application of 3D printing technique in bone tumor surgery: state of the art / 中华骨科杂志

ABSTRACT

It is a great challenge for surgeons to make an individualized treatment plan and remove tumor accurately and completely for bone tumor patients.3D printing technique is one of the most effective methods when it comes to individualized and precise treatment in medical field.The distinctiveness and advantages of 3D printing technique can make up for the shortcomings of traditional treatments,and it also can greatly improve the level and accuracy of individualized diagnosis and treatment in bone tumor surgery.3D printing technique is usually used to make anatomical models for plan or simulation;surgical guides for drilling or osteotomy;customized implants or prostheses;models for trimming grafts and models for implants in bone tumor surgery.3D printing technique is helpful to reduce operation time and bleeding,decrease radiation exposure,reduce complications and recurrence,cut the costs,and improve the surgical accuracy and clinical outcome.Through the review of 3D printing technology in bone tumor surgery literature,we analyzed and evaluated the following aspectssurgical time,bleeding,radiation exposure,clinical outcome,complications,recurrence,accuracy and costs.And the included literatures were analyzed and summarized from the positions of bone tumor and the uses of 3D printing technique.The purpose of this study is to summarize the application of 3D printing technique in treating bone tumor patients,and to make surgeons learn more about 3D printing technique,investigate the potential advantages and the developing tendency of 3D printing technique,and develop the new ideas of 3D printing technique in bone tumor surgery.
