Virtual preoperative planning and 3D printing are valuable for the management of complex orthopaedic trauma

Purpose:The technology of 3D printing(3DP)exists for quite some time,but it is still not utilized to its full potential in the field of orthopaedics and traumatology,such as underestimating its worth in virtual preoperative planning(VPP)and designing various models,templates,and jigs.It can be a significant tool in the reduction of surgical morbidity and better surgical outcome avoiding various associated complications.Methods:An observational study was done including 91 cases of complex trauma presented in our institution requiring operative fixation.Virtual preoperative planning and 3DP were used in the management of these fractures.Surgeons managing these cases were given a set of questionnaire and responses were recorded and assessed as a quantitative data.Results:In all the 91 cases,where VPP and 3DP were used,the surgeons were satisfied with the outcome which they got intraoperatively and postoperatively.Surgical time was reduced,with a better outcome.Three dimensional models of complex fracture were helpful in understanding the anatomy and sketching out the plans for optimum reduction and fixation.The average score of the questionnaire was 4.5,out of a maximum of 6,suggesting a positive role of 3DP in orthopaedics.Conclusion:3DP is useful in complex trauma management by accurate reduction and placement of implants,reduction of surgical time and with a better outcome.Although there is an initial learning curve to understand and execute the VPP and 3DP,these become easier with practice and experience.

尽管有前进，多重复杂受伤病人的管理在现代医疗保健仍然是大挑战。我们在场与双边的部分大腿骨的柄联系的双边的不稳定的骨盆的破裂的一个稀罕案例断裂。我们建议了如此的复杂损害模式的机制并且讨论了管理的计划。在稳定病人的医学上帮助了我们的病人克服这些严重、致命的损害后不久，我们相信修理所有专业的及时、好攻击的外科的干预断裂。由进行为如此的复杂破裂的管理建立一个最佳的协议是必要的未来并且 multicentric 以后学习。
