Comparative Study with and without the Use of 3D Prototyping of an Unconventional Technique in the Surgical Planning of Revision of Total Hip Arthroplasty.

This article presents a comparison between two cases in which there was a need for revision of total hip arthroplasty due to aseptic acetabular failure. We used 3D prototyping in one of the cases to perform an unconventional technique of molding synthesis material before the procedure to evaluate the time saved in the transoperative period in complex cases.

Abstract This article presents a comparison between two cases in which there was a need for revision of total hip arthroplasty due to aseptic acetabular failure. We used 3D prototyping in one of the cases to perform an unconventional technique of molding synthesis material before the procedure to evaluate the time saved in the transoperative period in complex cases.

Resumo Este artigo apresenta uma comparação entre dois casos em que havia a necessidade de revisão de artroplastia total de quadril por falha acetabular asséptica. Utilizamos prototipagem em 3D em um dos casos para realizar uma técnica não convencional de moldagem de material de síntese antes do procedimento, com objetivo de avaliar o tempo economizado no transoperatório em casos complexos.

Use of 3D Printing in Planning the Reconstruction of Total Hip Arthroplasty: A Teaching Tool.

The present study aims to demonstrate how biomodels can be used as teaching tools for surgical techniques and training in a medical residency service. A case series was carried out in our orthopedics and traumatology outpatient facility using three-dimensional (3D) printing for surgical planning to contribute to the surgical teaching and training of resident physicians. Two cases were selected as examples in the present article. Biomodels enable a better understanding of the surgery by the surgical team and residents, reducing the surgical time and the risks for the patients. These models can be a good teaching method to plan reconstructions of total hip arthroplasties, evaluate and predict surgical difficulties, and optimize procedures.

Resumo O objetivo deste trabalho é demonstrar como os biomodelos podem servir como ferramenta de ensino para o esclarecimento de técnicas cirúrgicas e o treinamento em um serviço de residência médica. Foram realizadas séries de casos em nosso ambulatório de ortopedia e traumatologia, nos quais o uso da prototipagem para o planejamento cirúrgico contribuiu para o ensino cirúrgico e treinamento de médicos residentes. Dois casos foram selecionados como exemplo neste artigo. O uso de biomodelos permite um melhor entendimento da cirurgia pela equipe cirúrgica e pelos residentes, e diminui o tempo e os riscos cirúrgicos aos pacientes. O uso de biomodelos no planejamento de reconstruções da artroplastia total do quadril pode servir como um bom método de ensino, para a avaliação e previsão das dificuldades no momento da cirurgia, e para otimizar os procedimentos.

Using body donor demographics to assist the implementation of donation programs in Brazil.

The use of human material in anatomy education depends upon the generosity of body donors. However, little is known regarding the demographics of body donors in Brazil, where voluntary body donation is a relatively rare phenomenon. Hence, the aim of the present study was to elucidate the demographic profile of applicants to the Body Donation Program (BDP) at the Federal University of Health Sciences of Porto Alegre in Brazil, as well as to assess whether the observed characteristics of body donors are unique to that sample, or if they merely reflect the characteristics of the regional population. Information derived from the specific forms filled out by donors between January 2008 and June 2016 at the time of registration were collected. Data from 416 forms were analyzed. Based on this study, the typical applicant in Brazil is typically a white female (67.4%), over 60 years of age (60.3%), unmarried or single (70.6%), affiliated with a religious group (89.1%), of middle class background (40.4%), who has completed high school and/or holds a university degree (93.8%). The motivation of donors was, in most cases, an altruistic gesture, represented by the desire to help society and science. Elucidating these demographic characteristics of potential donors may help identify the target public to which information regarding body donation campaigns could be directed.
