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...

Spine-Ghost: A New Bioactive Cement for Vertebroplasty
Vitale-Brovarone, Chiara; Pontirolli, Lucia; Novajra, Giorgia; Tcacencu, Ion; Reis, Joana; Manca, AntonioAn innovative, resorbable and injectable composite cement (Spine-Ghost) to be used for augmentation and restoration of fractured vertebrae was developed. Type III α-calcium sulfate hemihydrate (CSH) was selected as the bioresorbable matrix, while spray-dried mesoporous bioactive particles (SD-MBP, composition 80/20% mol SiO2/CaO), were added to impart high bioactive properties to the cement; a glass-ceramic con...
Bioactive glass/polymer composite scaffolds mimicking bone tissue
Gentile, Piergiorgio; Mattioli-Belmonte, Monica; Chiono, Valeria; Ferretti, Concetta; Baino, Francesco; Tonda-Turo, Chiara; Vitale-Brovarone, ChiaraThe aim of this work was the preparation and characterization of scaffolds with mechanical and functional properties able to regenerate bone. Porous scaffolds made of chitosan/gelatin (POL) blends containing different amounts of a bioactive glass (CEL2), as inorganic material stimulating biomineralization, were fabricated by freeze-drying. Foams with different compositions (CEL2/POL 0/100; 40/60; 70/30 wt %/wt)...
