Exploration of cultivating influence of making mobile medical softwares in orthopedic trauma on medical undergraduates' innovation capacity / 中华医学教育探索杂志

For the current situation of the time background and the cultivation of innovation ability of undergraduates, the problems of fracture classification, function evaluation and postoperative rehabilitation were realized by a software research team which mainly consisted of medical undergrad-uates. We put the project into practice in forms of software production and software promotion trial separately in the field of teaching and clinical practice to encourage students to be involved in learn-ing in the process of software production of professional knowledge. The implementation of the project worked well, and developed the well-designed relevant mobile software which was convenient in clini-cal practice and acquired computer software copyright, indicating that it can effectively motivate the undergraduates' innovation interest and consciousness through participating in the various links and the software production process, and it can also contribute to the cultivation of the comprehensive practical and innovation ability of medical undergraduates.

Application of computer-aided osteotomy template design in treatment of developmental dysplasia of the hip with steel osteotomy / 南方医科大学学报

<p><b>OBJECTIVE</b>To provide an accurate method for osteotomy in the treatment of developmental dysplasia of the hip with steel osteotomy by three-dimensional reconstruction and Reverse Engineering technique.</p><p><b>METHODS</b>Between January 2011 and December 2012, 13 children with developmental dysplasia of the hip underwent steel osteotomy. 3D CT scan pelvic images were obtained and transferred via a DICOM network into a computer workstation to construct 3D models of the hip using Materialise Mimics 14.1 software in STL format. These models were imported into Imageware 12.0 software for steel osteotomy simulation until a stable hip was attained in the anatomical position for dislocation or subluxation of the hip in older children. The osteotomy navigational templates were designed according to the anatomical features after a stable hip was reconstructed. These navigational templates were manufactured using a rapid prototyping technique.</p><p><b>RESULTS</b>The reconstruction hips in these children show good matching property and acetabulum cover.</p><p><b>CONCLUSION</b>The computer-aided design of osteotomy template provides personalized and accurate solutions in the treatment of developmental dysplasia of the hip with steel osteotomy in older children.</p>
