ABSTRACT
Abstract: Introduction: although pediatric orthopedic surgeons worldwide perform scoliosis surgery, the training received is variable and poorly understood. By surveying the European Pediatric Orthopedic Society (EPOS) and the Sociedad Latinoamericana de Ortopedia (SLAOTI), we aim to characterize this variability. Material and methods: in 2021, we distributed an anonymous online questionnaire to EPOS and SLAOTI. Results: 43% EPOS and 22% SLAOTI perform scoliosis procedures (p < 0.05). 18% EPOS and 2% SLAOTI performed > 35 procedures annually (p < 0.05). 70% EPOS and 27% SLAOTI received formal training in spinal deformity surgery (p < 0.005). Conclusions: results show significant differences in training and performance of scoliosis procedures between societies.
Resumen: Introducción: aunque muchos cirujanos ortopédicos pediátricos alrededor del mundo realizan cirugías para la escoliosis, el entrenamiento es variable y poco conocido. A través de encuestar a la Sociedad Europea de Ortopedia Pediátrica (EPOS) y a la Sociedad Latinoamericana de Ortopedia (SLAOTI) queremos caracterizar esta variabilidad. Material y métodos: distribuimos un cuestionario anónimo en 2021 a los miembros de EPOS y SLAOTI. Resultados: realizan las cirugías de escoliosis 43% de EPOS, en comparación con 22% de SLAOTI (p < 0.05); 18% de EPOS realizó > 35 cirugías al año, en comparación con 2% de SLAOTI (p < 0.05); 70% de EPOS y 27% de SLAOTI recibieron capacitación formal en cirugía de deformidades de la columna (p < 0.005). Conclusiones: los resultados de este estudio subrayan las diferencias en el entrenamiento de las cirugías de escoliosis entre diferentes sociedades.
ABSTRACT
@#AIM: To investigate the application and effect of virtual-reality surgery exercise in minimally invasive cataract surgery training for ophthalmology residents.<p>METHODS:Twenty ophthalmology residents with equal seniority who had completed 3a standardized residency training in the Affiliated Eye Hospital of Nanjing Medical University from 2019 to 2021 were prospectively enrolled. After passing the theoretical examination, residents were randomly divided into virtual surgery exercise(Dry-lab)group(<i>n</i>=10)and real animal surgery exercise(Wet-lab)group(<i>n</i>=10). Dry-lab and Wet-lab group residents performed training using the Eye SI surgical simulator and pig eye respectively. At the end of the training, the overall training effects of the residents in both groups were rated using the Eye SI surgical simulator and the real pig eye operation, and the module training effects of the residents in both groups were rated using the virtual surgical simulator. Furthermore, a questionnaire survey was used to objectively evaluate the two training methods.<p>RESULTS:Residents in Dry-lab group had significantly higher total scores on both operation assessments,simulator assessment and real pig eye operation assessment than Wet-lab group(88.03±1.34 <i>vs</i> 80.35±2.87, 87.50±3.03 <i>vs</i> 77.60±5.62, 88.57±1.89 <i>vs</i> 83.10±3.22, all <i>P</i><0.01). The simulator module assessment results showed that the residents in Dry-lab group scored significantly better than Wet-lab group in terms of scores and completion time on each module(<i>P</i><0.01). The questionnaire results showed that Dry-lab group rated better than Wet-lab group in terms of the novelty of training, the proximity to the real surgical experience, the degree of help to the improvement of microsurgery skills, the confidence to perform real surgery, and the overall satisfaction of surgical training(<i>P</i><0.05). <p>CONCLUSION:Applying virtual-reality surgery exercise to cataract surgery skills training for ophthalmology residents can significantly improve the cataract skills, increase overall training satisfaction, and help residents enhance their confidence, psychological quality, decision-making, and processing ability during real surgery at the initial stage of practice. This provides a new standard and model for establishing a formal and standardized cataract surgery training system for ophthalmology residents.
ABSTRACT
In recent years, the virtual surgery training system with force feedback has provided a new way for young doctors to improve their surgical skills in a safe, efficient and flexible training method. Precise drilling force and realistic hand feeling of manipulation are the cruxes in the virtual surgery training, and the accurate simulation of bone drilling depends on the accurate establishment of drilling force prediction model. The establishment of force prediction model with finite element analysis is the key part in the development of virtual training system. In this paper, the current research status of finite element analysis of bone drilling presented in four aspects: bone model reconstruction, material model, mesh model and prediction of drilling force, especially the construction of bone tissue material model is discussed in detail and several important models are analyzed. This paper presented a relatively complete overview of the approaches commonly used in this research field to promote the establishment of more accurate force prediction models of bone drilling.

ABSTRACT
With the deepening of the reform of public hospitals at the county level,as well as the development of medical technology personnel training and medical technology development in county hospitals,county hospitals should be able to make use of the latest technology to undertake the common diseases and frequently occurring diseases of county residents.So at present,the teaching hospitals affiliated to medical universities should carry out the short-term training of the latest special techniques in the training of the regular doctors.Department of Urology of the first Affiliated Hospital of Chongqing Medical University,in the 3 month training cycle,with improving the self-learning ability of the refresher doctors as the core,carried out the hand by hand teaching of small classes and introducing model teaching,which achieved good results.
