Department of orthopedics, Yanan hospital set up 3D printing Clinical Center

3D printing clinical research center of Department of orthopedics, Yanan hospital, Kunming. At present, orthopaedics has been successfully implemented 3D printing technology and "bridging combination type internal fixation system combined application, complex fracture trauma, orthopedic surgery and other complex orthopaedic disease patients to provide personalized treatment, shorten the operation time, increase the safety of operation.

It is understood that Kunming Yanan hospital is the province in the field of orthopedics only state-level key clinical specialist, the establishment of a new 3D printing clinical research center, combined with the hospital director of orthopaedic bears and eagles, independent research and development of "bridging combined internal fixation system" patent, in order to realize the precise treatment, personalized treatment lay the foundation.

Department since the 3D printing technology has been carried out, has achieved complex fracture surgery, spinal deformity surgery preoperative 1:1 physical model of print making, and with in vitro simulated fracture reduction and make more accurate surgical planning, shorten the operation time, reduce the injury in the operation.

3D printing technology in the medical industry, has been widely used. In orthopedics application. In the preoperative can according to the patient's CT scan, construct and real was 1: 1 of the 3D model, disease diagnosis, preoperative surgical plan design, operation assisted operation and operation after recovery to provide a reference. Through digital three-dimensional model can more intuitive, more accurate to reflect the three-dimensional structure of the skeletal lesions and clinicians on the diagnosis, surgical planning, choice of internal fixation provides help, improve the operation accuracy, reduce the operation time, incision minimized.

Department of orthopedics, the person in charge said, 3D printing model for the diagnosis of disease has important significance. For example in bone tumor patients, can print out of tumor on CT values, guide the development of surgical planning, operation simulation, and according to the 3D printing of bone and joint prototype, plan into medullary cavity of equipment size and medullary cavity structure variation and equipment structure difference of patients to the better placed in the prosthesis and improve surgical safety and accuracy.

And 3D printing of bone and joint prototype can also may appear in the operation process of foresight, such as the remains of the 3-D shape of the bone defect area after the operation, the parameters of the internal fixation device or prosthesis personalized, internal fixation screw positioning. To provide basis for preoperative preparation, improve the efficiency of operation. In addition, 3D printing model can also for scoliosis, limb fractures, metaphyseal bone nonunion Bone, pelvis fracture etc. patients were preoperative modeling, the preparation of 3D model or use guide auxiliary screw and internal fixation materials for precise placement, shorten the operation time of patients, reduce the occurrence of complications.
