Application of an innovational hybrid simulation-based education of bone traction with co-Debriefer for medical students / 中华医学教育探索杂志

Objective:To develop an innovational hybrid simulation-based education of bone traction with co-Debriefer for medical students and to evaluate its effectiveness.Methods:This study was designed as a cross-controlled study. From June 2018 to June 2019, 28 medical students were randomized into two groups. The two groups adopted simulation-based education and traditional teaching method respectively. In the second week of internship, the teaching methods of the two groups exchanged. Scores rating of the skill were used to assess the students' performance in the end of each teaching methods. SPSS 23.0 software was used to analyze the collected data.Results:In the first weekend of orthopedic-internship, students in the experimental group scored significantly higher than the control group, with an average score of 85.07 points versus 67.92 points. In the second weekend of practice, there was no obvious change in the skill score of the experimental group, but the score of the control group was significantly improved, and there was no obvious difference with the experimental group.Conclusion:The hybrid simulation-based education with co-debriefing is a reliable teaching method for medical interns to learn skills of bone traction, which can effectively help improve students' skills, reduce their errors, and ensure patient's safety.

Technical progress of craniomaxillofacial surgery / 中华整形外科杂志

Clinical application of imaging technology (e.g., CT, MRI and DSA) in craniomaxillofacial surgery, genetic detection and analysis, three-dimensional visualization of panoramic anatomy, rapid and accurate molding of craniofacial skeletal models, precise designing and manufacturing technology, intraoperative real-time navigation system, and the remote consultation system aided by information network technology effectively improve the diagnosis and treatment of craniomaxillofacial malformation.Application of rigid internal fixation improves the stability and accuracy of the fracture treatmentand osteotomy. With the research and application of distraction osteogenesis(DO) in craniomaxillofacial surgery, DO in Le Fort III osteotomy and treatment on hemifacialmicrosomiareduce postoperative recurrence significantly. The combination of craniomaxillofacial surgery and advanced technology of related medical and engineering disciplines has promoted the development of craniomaxillofacial surgery.

Experience of the bone traction treatment for displaced fracture of femur shaft in children / 临床外科杂志

Objective To review the experience of the bone traction treatment for displaced fracture of femur shaft in children.Methods All of the cases were treated with femur supercondylar traction,and they were fixed in a stable position with hip joint in 90? flexion and 30?~45? abduction and with knee in 90? flexion.Result The effects of 86 cases were satisfactory.Conclution This method is simple and effective.It reduces complications of skin traction and operation to patients.
