Percutaneous vertebroplasty: a new animal model.
Oliveira, Maria Teresa; Potes, José; Queiroga, Maria Cristina; Castro, José; Pereira, Alfredo; Rehman, Sarrawat; Dalgarno, Kenneth; Ramos, AntónioBackground Context Percutaneous vertebroplasty (PVP) is a minimally invasive surgical procedure and is frequently performed in humans who need surgical treatment of vertebral fractures. PVP involves cement injection into the vertebral body, thereby providing rapid and significant pain relief. Purpose The testing of novel biomaterials depends on suitable animal models. The aim of this study was to develop a repr...

Development of a sheep vertebroplasty model for bioceramic materials assessment
Lucena, Sónia; Oliveira, Maria Teresa; Potes, José; Queiroga, Maria Cristina; Rehman, Sarrawat; Dalgarno, Kenneth; Ramos, António; Reis, JoanaDevelopment of a sheep vertebroplasty model for bioceramic materials assessment Sheep has been widely used as an animal orthopaedic model. Although several studies report anatomic and biomechanical similarities as well as distinctions of ovine lumbar vertebrae when compared to human’s, only a few studies describe its actual use as a vertebroplasty model. Due to distinct anatomic features, sheep lumbar vertebrae...
Ex Vivo Model for Percutaneous Vertebroplasty
Oliveira, Maria Teresa; Lucena, Sonia; Potes, José; Queiroga, Maria Cristina; Rehman, Sarrawat; Dalgarno, Kenneth; Ramos, António; Reis, JoanaThe testing of novel biomaterials for percutaneous vertebroplasty depends on suitable animal models. The aim of this study was to develop ex vivo a reproducible and feasible model of percutaneous vertebroplasty, for ulterior application in vivo. A large animal model was used (Merino sheep), due to its translational properties. Vertebroplasty was performed under tactile and fluoroscopic control, through a bilate...
Modelo animal ex vivo para vertebroplastia percutânea
Oliveira, Maria Teresa; Potes, José Caeiro; Queiroga, Maria Cristina; Rehman, Sarrawat; Dalgarno, Kenneth; Ramos, António; Reis, JoanaO teste de novos biomateriais para vertebroplastia percutânea (VP), depende da escolha de um modelo animal adequado. O objectivo deste estudo foi o desenvolvimento ex vivo de um modelo animal reprodutível e fiável para VP, para posterior aplicação in vivo, tendo em consideração a necessidade de evitar o derrame de cimento para o canal vertebral e estruturas vasculares adjacentes. Foi seleccionado um modelo anim...
