The fixation of fractures in wild animals has been a great challenge for veterinarians, because they will inevitably face unique anatomical characteristic with scarce studies or reports published. Fracture should promote adequate stability and early return to limb function, taking into account biomechanical characteristics the bones, body weight, natural habits wildlife. Three bone from two giant anteaters (Myrmecophaga tridactyla) referred at veterinary teaching hospital on different...

ABSTRACT Intramedullary nails are the focus of scientific studies in small animal orthopedic surgery because use these materials fractures immature, small-sized patients, and proximal bone regions is challenging. In this context, elastic osteosynthesis has been strongly advocated for treatment patients under four months age. Therefore, objective study was to report two cases non-exposed complete femurs felines, resulting from trauma, both patientes six age, treated with technique using a...

ABSTRACT The treatment of fractures from the thoracic limb in giant anteaters is extremely challenging. Unfamiliar and peculiar anatomical characteristics, robust musculature imminent need for an early return to function highlight such challenges. objective this report was describe successful use osteosynthesis with a locking compression plate humeral fracture adult anteater. patient rescued on highway after being run over presented at Veterinary Teaching Hospital. Surgical stabilization...

ABSTRACT This study aimed to evaluate the effectiveness of bridge plating simple tibial fractures in dogs by minimally invasive plate osteosynthesis (MIPO). Medical and radiographic records twenty-nine with that underwent fixation MIPO were retrospectively evaluated. The clinical outcome was classified considering presence lameness at end treatment. mechanical joint angles measured compared values described literature. Additionally, fragment apposition implant disposition Based on modified...

ABSTRACT The objective of this study was to investigate the effect ketoprofen on preemptive analgesia in female cats submitted ovariohysterectomy. Sixteen healthy were distributed into two groups, with eight animals each, by means a draw, group (PREG), which animal received (1 mg/kg) subcutaneously hours before surgery; and postsurgery (POSG), administered immediately after surgery. In both given 24, 48 72 first adminstration. Heart respiratory frequencies glycemia measured all during days...

ABSTRACT: Bone trauma triggers an acute inflammatory response, which can alter the serum concentration of acute-phase proteins (PFA). We aimed to evaluate effectiveness PFA measurement as a laboratory biomarker for inflammation related bone regeneration. A partial ostectomy right radius was performed on 22 young male rabbits. The complete blood count, albumin, ceruloplasmin, haptoglobin, C-reactive protein, and transferrin levels were recorded correlated with radiographic evolution healing....

Introduction The aim of this study was to describe and evaluate a novel plate designed specifically for the canine ilium using finite element methods. cranial portion had an elliptical shape contained nine screw holes. caudal triangular with three Four screws were used at (screw 1 4) 5 7) segment plate. Finite models pelvis created. A load 300 N applied on femur-hip joint contact area. Values Von Mises Stress plate, maximum minimum main stresses in bone capture mechanical factors study....

This report describes the radiographic findings in a case of atlantoaxial instability associated with agenesis odontoid process axis an adult dog. Clinically, patient presented apathy and tetraparesis. A simple examination cervical region was performed, which allowed disclosure without articular changes. The normality index (ANI) 0.103 mm, indicating joint. conservative approach adopted by means collar, movement restriction anti-inflammatory therapy. We concluded that asymptomatic animals...

Purpose: This study compared, through biomechanical evaluation under ventral flexion load, four surgical techniques for stabilization of the atlantoaxial joint in dogs. Methods: In total, 28 identical models were created by digital printing from computed tomography images a dog, and specimens divided into groups seven. each group, different technique was performed: transarticular lag screws, polyaxial multiple screws bone cement (polymethylmethacrylate–PMMA), plate. After technique,...

Abstract Objective The aim of this article was to describe, in detail, the safe portals and surgical approaches for minimally invasive interlocking nail osteosynthesis. Methods Fifteen dog cadavers weighing between 30 40 kg were used, 10 an anatomical study 5 creation osteosynthesis portals. Anatomical dissections used establish landmarks precise interrelationships use nails tibia, femur, humerus. Subsequent dissection made evaluate potential iatrogenic lesions. Results reference points for,...

RESUMO Objetivou-se com este trabalho comparar biomecanicamente os posicionamentos dorsal e medial da placa bloqueada na artrodese do carpo em cães. Para isso, foram utilizados sete pares de membros torácicos cães eutanasiados por razões não relacionadas ao estudo, que estabilizados dorsal, seus respectivos posicionamento medial. Os as articulações radiocarpometacarpianas estabilizadas cirurgicamente submetidos a ensaio compressão axial máquina universal ensaios materiais, dados limite...

Introduction: Studies have shown motivating results considering bone union and reduced number of complications. Intramedullary interlocking nail-shave mechanical biological advantages when compared with plates, such as a greater preservation extra vascularization positioning on neutral axis.

Introduction: Intramedullary interlocking nails (ILN) are orthopedic implants used to stabilize fractures in humans and animals. New models have been being described aiming correct failures originated from excessive micromovement previous ones. The objective of this work is describe a novel veterinary intramedullary nail system with threaded angle-stable locking, which presents the distal holes two planes. It also instruments necessary for its implantation.

ABSTRACT The aim of this study was to evaluate the effect nandrolone decanoate (ND) on treatment bone nonunion in radius rabbits. Thirty-one, young adult, New Zealand White rabbits (Oryctolagus cuniculus) were allocated one four groups: males (NMG), females (NFG), placebo (NPM), and (NPF). After a 10 mm ostectomy confirmed (45 days after surgery), animals NMG NFG groups received mg/kg ND intramuscular once week for weeks, while 0.9% NaCl solution. Radiographic, histopathologic, densitometric...

Abstract Interlockings nails (IN) are orthopedic implants with superior mechanical and, potentially, biological qualities. Despite the countless and indisputable advantages of current angle-stable models, there still limitations for their use in certain scenarios. The objective present study was to describe biomechanically test a new orthogonal intramedullary nail model veterinary use. proposed has two 3.8-mm threaded cylindrical holes each its portions: proximal portion, 11 mm apart; distal...
