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.

A Galeazzi-variant type fracture-dislocation in adults

有在近似或远侧的桡尺骨的关节(DRUJ ) 的脱臼任何一个的半径或尺骨的 ObjectiveFracture 不是普通损害并且内在地是不稳定的。这里，我们报导一个案例系列，与与 DRUJ 的脱臼联系的两个骨头前臂破裂，作为 Galeazzi 变体的类型破裂脱臼，并且试着分析学习基于 6 个病人有的这损害 pattern.MethodsThe 不同年龄(20 ～ 45 年) 的 Galeazzi 变体的类型破裂脱臼。所有破裂是关上的类型。二破裂包含了一样的水平，三破裂在半径和尺骨柄的不同层次。在彻底的检查和调查以后，他们与有限接触被对待没有为 DRUJ.ResultsAll 案例的另外的固定的动态压缩板被跟随在上面为 24 个星期。最大的发生发生在在 31 和 40 年之间的年龄组。半径和尺骨的所有破裂在 12 个星期的平均时间被统一。在最后的后续的手腕和肘，旋后和内转的运动的范围是正常的。没有在任何在成年人的 cases.ConclusionGaleazzi 变体的 DRUJ 的随后的 re-subluxation 或脱臼是有手腕损害的前臂的一个新 undescribed 模式。稳定的开的减小和两个骨头前臂破裂的内部固定是强制的，为破坏 DRUJ 愈合在一个演员组到 3 ～ 4 星期固定列在后面。

Periprosthetic subtrochanteric femoral fracture in a megaprosthesis of the knee

我们在膝的 megaprosthesis 以后报导腿节的 subtrochanteric 区域的 periprosthetic posttraumatic 骨折的一个稀罕案例，做为抵抗有在 51 岁人的第二等的 osteoarthrosis 的远侧的腿节不属于工会。有锁住的治疗大腿骨的板能与好结果完成主要联合。
