Analysis of the Clinical Research of Three-Dimensional Printing Technology in Orthopedics / 中国医院管理

Objective To study onclinical researches of 3D printing technology in Orthopedics.Methods Through literature search,107 literatures were included and systematically reviewed,and the status of clinical researches of 3D printing technology in orthopedics was described.Results The clinical researches of 3D printing technology in Orthopedics were mainly focused on males and adults population conducted from 2007 to 2012.3D printing technology frequently used in Orthopedics were reduction and internal fixation,deformity correction,pedicle screw placement,tumor resection,revision and reconstruction,and knee replacement.Conclusion 3D printing technology in Orthopedics is still at an initial stage of clinical development.

Systematic Review of the Effect of Clinical Application of Three-dimensional Printing Technology in Orthopedics / 中国医院管理

Objective To assess the effect of clinical application of three-dimensional printing technology (3D printing) in Orthopedics.Methods Comparing the effect of clinical application of three-dimensional printing technology with traditional Standardized technology,through using a systematic review and Meta Analysis.Results Meta analysis of 25 studies included in the research showed that application of 3D printing reduced operation time by 26 minutes,decreased intraoperative blood loss by 77 ml,and increased accuracy rate or success rate of screw implanting(increased by 2.10 times compared with tradit onal standardized technology).Conclusion The application of 3D printing in Orthopedics has good short-term effect But its deVelopment in clinical application should be cautious.

Non-control Study Systematic Review of Safety and Effectiveness of Three-Dimensional Printing Technology in Orthopedic / 中国医院管理

Objective To evaluate the safety and efficacy of clinical application of three-dimensional printing technology (3D printing) in Orthopedics.Methods The safety and effectiveness of clinical application of three-dimensional printing technology in Orthopedics were analyzed by systematic review of non-control studies.Results Non-control studies showed that cortical perforation rate of screws was 3.83％ (calculated by the number of screw).Complication rate was 2.13％,surgical infection rate was 0.28％,prosthesis problematic rate was 0.79％,the average operation time was 139.23 minutes,and some results of the indicators for safety and effectiveness were similar between studies with and without control groups.Conclusion Although 3D printing application in Orthopedics has some clinical value,and its extension needs economic assessment.
