Ex vivo biomechanical testing of Funkquist B dorsal laminectomy between the six...
Galíndez,Julián Andres Sanjuan; Minto,Bruno Watanabe; Marinho,Paulo Vinicius Tertuliano; Dissenha,Adrielly; Lucena,Dayvid Vianeis Farias deABSTRACT: Dorsal laminectomy is routinely performed for spinal cord compressions or stenosis of the cervical vertebral canal. However, despite good results, relevant complications have been described in dogs. Considering the incomplete understanding of the necessity for complementary surgical stabilization after performing laminectomies in the cervical region, this study compared the resistance and range of mot...
Preliminary mechanical evaluation of two novel veterinary angle-stable-threaded...
Nóbrega,Jordana da Costa; Lucena,Dayvid Vianêis Farias de; Minto,Bruno Watanabe; Dias,Luis Gustavo Gosuen GonçalvesABSTRACT: The interlocking nail represents an excellent option as a surgical approach to treat fractures in long bones in veterinary medicine. However, failures were reported mainly due to a slack present in the interface of the rod with the screws. The present study tested and mechanically compare axial compression loads of two novel models of stable angle interlocking nails with threaded holes. Among the two ...
Correlation of serum acute-phase proteins with bone repair in rabbits (Oryctola...
Calciolari,Karina; Dissenha,Adrielly; Galíndez,Júlian Andrés Sanjuán; Lucena,Dayvid Vianêis Farias de; Rossignoli,Pedro Paulo; Rocha,Fabiana Del LamaABSTRACT: Bone trauma triggers an acute inflammatory response, which can alter the serum concentration of acute-phase proteins (PFA). We aimed to evaluate the effectiveness of PFA measurement as a laboratory biomarker for inflammation related to bone regeneration. A partial ostectomy of the right radius was performed on 22 young male rabbits. The complete blood count, albumin, ceruloplasmin, haptoglobin, C-reac...
Canal flare index evaluation for different dog breeds
Gomide,Paula Regina Silva; Souza,Luís Renato Veríssimo de; Andrade,Caroline Ribeiro de; Dreibi,Rafael Manzini; Santarosa,Bianca PaolaABSTRACT: This study determined the canal flare index (CFI) of four dog breeds using two distinct femoral regions as a reference. Thirty-five radiographs of the hip joints of Golden Retrievers (GRG), German Shepherds (GSG), Labrador Retrievers (LRG), and Rottweilers (RG) of both sexes were used. Seventy experimental units were submitted to CFI calculation. Objective (CFIob) and subjective (CFIsub) values of the...
Capital femoral physeal dysplasia in cats submited to ostectomy of the femoral ...
Moi,Tryssia Scalon Magalhães; Pires,Marco Aurélio Molina; Yamauchi,Kelly Cristiane Ito; Dias,Luís Gustavo Gosuen Gonçalves; Minto,Bruno WatanabeABSTRACT: This report described pathological fracture of the femoral head (physeal dysplasia) in four male cats (three mixed breed and one Bengal), with an average age of 16 months, treated by an ostectomy of the femoral head and neck. Three cats were neutered and one entire. All presented with mild intermittent lameness in the pelvic limbs. Displacement of the femoral epiphysis and resorption of the femoral ne...
Bone alignment after minimally invasive plate osteosynthesis of the tibia in dogs
Costa Junior,Jose Sergio; Dreibi,Rafael Manzini; Franco,Guilherme Galhardo; Dias,Luis Gustavo Gosuen Gonçalves; Giuffrida,Rogerio; Minto,Bruno WatanabeABSTRACT: This study assessed radiographically changes in tibial alignment in the frontal and sagittal planes in dogs that underwent minimally invasive plate osteosynthesis (MIPO) without the aid of image intensifiers. Radiographs of dogs with complete non-articular tibial fractures submitted to MIPO were included and evaluated, without the aid of a transoperative image intensifier and / or an association of im...
Biomechanical evaluation of a new femoral stem design for total hip replacement...
Faria,Luís Guilherme de; Minto,Bruno Watanabe; Shimano,Antonio Carlos; Macedo,Ana Paula; Diogo,Lucia Maria Izique; Dreibi,Rafael Manzini; Nobile,MatheusABSTRACT Purpose To evaluate the biomechanical properties of a novel total hip replacement femoral stem. Methods Eight pairs of femurs from dog cadavers were used. The femurs were separated into different groups. A novel femoral stem with a convex proximal portion (Stem B) was biomechanically evaluated and compared to awell-known veterinary collared stem (Stem A). Femoral stems were inserted into the contralate...
Cervical ventral slot in rabbits (Oryctolagus cuniculus). Piezosurgery versus c...
Roscamp,Marcelo; Hataka,Alessandre; Zambon,Frederico Carlini; Ferreira,Danyelle Rayssa Cintra; Minto,Bruno Watanabe; Dias,Luis Gustavo Gosuen GonçalvesABSTRACT Purpose To investigate the applicability of piezosurgery for cervical ventral slot (CVS), comparing it with the conventional technique of using high-speed burs for bone wear. Methods Thirty rabbits (Oryctolagus cuniculus) were divided into two treatment groups (T1 and T2) corresponding to CVS between C3-C4. In T1, the surgery was performed with piezoelectric apparatus, and in T2 with high-speed burs. T...
Percutaneous application of allogeneic adipose-derived mesenchymal stem cell in...
Franco,Guilherme Galhardo; Minto,Bruno Watanabe; Dreibi,Rafael Manzini; Costa Junior,Jose Sergio; Dias,Luis Gustavo Gosuen GonçalvesABSTRACT Purpose To evaluate clinical outcome following minimally invasive plate osteosynthesis (MIPO) associated with percutaneous transplantation of allogeneic adipose-derived mesenchymal stem cells (AD-MSC) at the tibial fracture site in dogs. Methods Thirty-six dogs presenting with nonarticular complete tibial fracture were included in this study. All fractures were treated by the same MIPO technique. The a...
Three-dimensional printed poly (L-lactide) and hydroxyapatite composite for rec...
Minto,Bruno Watanabe; Sprada,Arícia Gomes; Gonçalves Neto,José Aloizio; Alcântara,Brenda Mendonça de; Rocha,Thiago André Salvitti de SáABSTRACT Purpose To use a 3D printed poly (L-lactide) acid (PLLA) and hydroxyapatite (HA) composite as a bone substitute for reconstruction of a critical bone defect in the radius of rabbits. Methods A 1.5 cm ostectomy was performed in the radial diaphysis of 60 New Zealand white rabbits. The rabbits were divided into three groups according to surgical treatment of the bone defect (group I – control, group II –...
