Background: Pelvic fractures are commonly ecountered in cats. The ilium is included in approximately 50% of pelvic fractures in cats. Although conservative management of the pelvic fracture is known to have good prognosis, surgical fixation is recommended for the pelvic fracture with ilial fractures. 3D printing is an accurate digital modeling method by converting two-dimensional (2D) images into 3D model. 3D printing in veterinary medicine has been described in the various orthopedic diseases such angular limb deformities or fractures. The use of 3D model for presurgical planning is helpful to improve the results of complex surgical interventions. The objective of this study is to identify the usefulness of fabricating 3D models based on allogenic 2D data with aid of 3D printer program. Case: A 4-year-old spayed female domestic shorthair cat presented with hindlimb lameness. Radiography revealed left ilial body fracture with multiple fractures including left tuber ischium, pubic symphysis, and bilateral cranial ramuses of pubis. Digital imaging and communication in medicine (DICOM) files of the complete ilium were extracted from a computed tomography (CT) scan of a healthy and castrated male cat of same breed. Volume rendering images were prepared by Slicer program based on DICOM files. After acquired 3D data were converted to STL (Standard Triangulation Language) file for the 3D printing machine, non-fracture involved area was removed except the left ilium using the Meshmixer® software and then data was stored as STL files again. The length of 3D model was adjusted to actual size using 3D printer firmware based on actual size of the ilial length. Subsequently, 3D modelling was performed using 3D printer. The plate was precontoured to conform to the lateral surface of the 3D model. Internal fixation using precontoured plate resulted in accurate bone alignment. The alignment of the ilium remained appropriate throughtout the follow-up period. Complete union was identified 6 months after surgery. Discussion: Although the most common method for the ilial fractures is the application of bone plates to the lateral side of the ilium, bone plate fixation is more challenging in cats owing to the small bone size and small surface area of the fracture sites compared to dogs. Therefore, it is important to make accurate presurgical planning for successful result of a surgery. 3D printing based on actual patient have several limitations including time for complete printing process and additional anesthetic episode to acquire CT images. However, in simple cases, a presurgical CT scan may not be necessary if the plate can be precisely precontured based on the data from the other patient. In this way, the additional financial burden for CT examination also might be reduced. On the other hand, technical difficulty of utilizing hardware and software, and financial availability were another drawback. However, in this current study, most of limitations regarding conventional 3D printing based on actual patient were overcome by the application of the fused deposition modeling (FDM) technology with allogenic data. In the current study, total time for fabrication of 3D model based on FDM technology, was less than 3 h, which are much shorter than the time for conventional 3D printing. The difference of the ilial length between the actual patient and the 3D model was adjusted through the firmware program. Thus, differences of the conformation or size between the 3D model and the ilium of the patient was negligible during the surgery, although 2D images were not acquired from actual patient. Intraoperative contouring of the plate was not required. In conclusion, through presurgical plate contouring by the 3D bone template based on non-patient specific data, successful treatment of the ilial fracture was possible.

Background: Coxofemoral dislocation is uncommon in large animals, due to anatomical particularities that provide greater stability to this joint. The most common causes of hip dislocation in large animals are related to hypocalcemia, mount trauma, sudden falls on hard surfaces or dystocia. Treatment can be performed by closed reduction, but the reported results are not satisfactory with complications. Several surgical techniques have already been described and successfully used in small animals in the treatment of hip dislocation. The present work aims to describe the technique and the result of the iliofemoral suture in the treatment of hip dislocation in a Girolando heifer. Case: A heifer was attended with a history of difficulty in getting up. According to the owner, the clinical manifestation was sudden, after remaining in a paddock with other animals of different age groups. The calf had reduced skin sensitivity on the croup, and it was impossible to remain in the quadrupedal position, often remaining in sternal recumbency with the left pelvic limb in extension. From the clinical examination, spinal cord injury was suspected and clinical treatment was instituted with dexamethasone, vitamins B1, B12 and dimethylsulfoxide. At the end of the clinical treatment, the animal did not show a favorable evolution, so radiographic examination of the coxofemoral region was performed, revealing dislocation of the left femoral head, indicating surgical correction. Xylazine was administered as pre-anesthetic medication, followed by anesthetic induction with midazolam associated with ketamine, followed by orotracheal intubation. Anesthetic maintenance was instituted with isoflurane and monitoring was performed with a multiparameter monitor. An epidural block was performed with bupivacaine and morphine. A craniolateral approach to the left hip joint was performed. After the dislocation was reduced, sutures were used to better stabilize the joint in question. Following the evolution of the surgical procedure, it was possible to confirm that the femoral head remained in place. After 15 days, the skin stitches were removed and the animal was discharged from the hospital and returned to its original property. The calf was asked to remain in the stall for at least 60 days, gradually releasing it into larger spaces and only after 120 days could it remain in the paddock with other animals. During three months, the tutor was consulted about the evolution of the condition, reporting that the animal was clinically well, being able to get up and walk without difficulty and with a mild degree of lameness, thus suggesting the success of the surgical procedure. Discussion: There are few studies of successful surgical treatments of hip dislocation in large animals, and that number is even smaller when considering cattle alone. It is believed that this is due to difficulties related to the surgical technique and to postoperative handling, given the animal's weight. The iliofemoral suture technique performed on the animal in the present study is commonly employed in small animals, and excellent results have been observed. However, reports on the use of this technique in large animals have not been found. The iliofemoral suture technique has advantages over other reported surgical techniques in cattle. When compared to the femoral head and neck resection, the iliofemoral suture has several advantages, as it allows preservation of the joint and achievement of superior biomechanical results. When compared to the technique of reinforcement of the joint capsule with synthetic material, also reported in cattle, the iliofemoral suture appears to be faster, simpler and more economic, and provides similar stability. We conclude that the iliofemoral suture proved to be a satisfactory alternative for the treatment of hip dislocations in young cattle.

Twelve dogs with traumatic hip luxation were selected for surgical intervention with a modified iliofemoral suture technique using an anchor screw to substitute the passage of suture material through a perforated tunnel in the ilium. Six procedures were performed with non-absorbable suture and other six with absorbable suture materials. These cases were evaluated at 15, 30, 60, and 90 days after surgery by performing an ambulation analysis and palpation of the joint. In all cases, there was a return of partial and total limb support in an average of 3 and 19 postoperative, respectively. The fixation strategy of the suture material in the ilium using an anchor screw proved to be efficient with a smaller surgical approach and lesser surgical difficulty, maintaining joint congruence in acute as chronic luxation cases. The use of absorbable and non-absorbable sutures had excellent clinical results, but there was a subjective superiority of the first ones, once 4 dogs of the non-absorbable group presented some discomfort during the postoperative palpation of the joint, 90 days after surgery.(AU)
Doze cães com luxação coxofemoral traumática foram submetidos à intervenção cirúrgica de sutura iliofemoral modificada com uso de parafuso âncora substituindo a passagem de fio através de túnel perfurado no ílio. Seis procedimentos foram realizados com fio não absorvível, e outros seis com fio absorvível. Os casos foram avaliados aos 15, 30, 60 e 90 dias após a cirurgia, por meio de análise de deambulação e palpação articular. Em todos os casos, houve retorno de suporte parcial e total do peso no membro operado, em média, aos três e 19 dias de pós-operatório, respectivamente. A estratégia de fixação do fio de sutura no ílio com parafuso âncora se mostrou eficaz, permitindo uma abordagem cirúrgica menos invasiva, com menor dificuldade na execução, garantindo manutenção da congruência articular tanto em quadros de luxação aguda como crônica. O uso de fio absorvível e não absorvível teve bons resultados clínicos, porém houve uma superioridade subjetiva do primeiro, uma vez que quatro pacientes do grupo fio inabsorvível mostraram desconforto à palpação da articulação aos 90 dias após a cirurgia.(AU)

Background: Coxofemoral luxation is the most common traumatic luxation in dogs and the iliotrochanteric suture is one of the surgical treatment options. The orthopedic suture aimed at surgically restoring joint movement should be employed in an isometric manner in order to maintain adequate tension throughout the arc of motion. This study aimed to determine the isometric points for the iliotrochanteric suture in dogs during the joint extension and flexion movements. This evaluation was performed both in the intact hip joint and in the luxation model, establishing the best combination, among the determined points, for the reestablishment of normal joint movement. Materials, Methods & Results: Radiographic analyses of 12 canine cadaveric hips, both intact and in craniodorsal luxation model, were performed in a neutral position, flexion at 50°, and extension at 150°. In the trochanteric segment, two parallel lines were drawn, creating the central vertical axis and the secondary vertical axis. Three points were then determined on each axis, from proximal to distal, corresponding to 25, 50, and 75% of the height of the axis, and were labelled as T1, T2, and T3 and T4, T5, and T6, respectively. In the iliac segment, a line perpendicular to the longitudinal axis of the ilium was drawn, and 25, 50, and 75% of this height corresponded to points I1, I2, and I3, respectively. The lengths between the points were measured, with the objective of evaluating which combination of points presented less variation in the joint positions. The central location of the iliac and trochanteric segments, determined respectively by I2 and T2, provided smaller variations during the maximal movements of hip flexion and extension. Discussion: The surgical techniques of iliotrochanteric suture target to maintain the internal rotation of the femoral head inside the acetabulum and abduction of the femur until...

In veterinary medicine, the cell therapy is still unexplored and there are many unanswered questions that researchers tend to extrapolate to humans in an attempt to treat certain injuries. Investigating this subject in nonhuman primates turns out to be an unparalleled opportunity to better understand the dynamics of stem cells against some diseases. Thus, we aimed to compare the efficiency of bone marrow mononuclear cells (BMMCs) and mesenchymal stem cells (MSCs) from adipose tissue of Chlorocebus aethiops in induced bone injury. Ten animals were used, male adults subjected, to bone injury the iliac crests. The MSCs were isolated by and cultured. In an autologous manner, the BMMCs were infused in the right iliac crest, and MSCs from adipose tissue in the left iliac crest. After 4.8 months, the right iliac crests fully reconstructed, while left iliac crest continued to have obvious bone defects for up to 5.8 months after cell infusion. The best option for treatment of injuries with bone tissue loss in old world primates is to use autologous MSCs from adipose tissue, suggesting we can extrapolate the results to humans, since there is phylogenetic proximity between species.(AU)

Foram utilizados 10 animais, adultos do sexo masculino, submetidos à lesão óssea nas cristas ilíacas. As MSCs foram isoladas e cultivadas; de forma autóloga, as BMMCs foram infundidas na crista ilíaca direita e as MSCs de tecido adiposo na crista ilíaca esquerda. Após 4,8 meses, a crista ilíaca direita foi totalmente reconstruída, enquanto a crista ilíaca esquerda continuou apresentando defeito ósseo evidente por até 5,8 meses após a infusão. A melhor opção para o tratamento de lesões com perda de tecido ósseo em primatas do Velho Mundo é a utilização de MSCs autólogas de tecido adiposo, sugerindo que se podem estender os resultados para seres humanos, uma vez que há proximidade filogenética entre as espécies.(AU)

Background: Fractures and dislocations are common orthopedic conditions arising from traumas from anthropic interaction on wild species, such as those caused by road trampling. Among the treatments, osteosynthesis is considered the method of choice in the treatment of fractures, such as ilium body fractures and femoral fractures. Based on this context, with regard to the incidence of auto accidents and few studies describing osteosynthesis techniques for crab-eating fox, the present study aimed to report the osteosynthesis performed on the body of the ileum and femur of a wild specimen of Cerdocyon thous. Case: A female, adult, crab-eating fox (Cerdocyon thous), coming from wild life was referred to hospital care with a history of run over. After specific examinations, it was diagnosed a complete transverse femoral shaft fracture, an oblique ilium body fracture, a pubic and ischial fracture, and pelvic canal narrowing. The treatment instituted was osteosynthesis of the femoral and ilium body fractures through the use of a 2.7 mm locking plate and screws. In the postoperative period, radiographic examination was performed, where bone callus formation was observed in the 5th week and bone remodeling and consolidation in the 11th week. After 140 days of rehabilitation, the animal was able to be released in the wild, with effective return of function of the pelvic limbs. The release was performed by environmental agencies in a national natural reserve, using radio necklace monitoring.Discussion: Osteosynthesis techniques and preoperative and postoperative management proved to be effective for the return of adequate function of the pelvic limbs in Cerdocyon thous. For wild animals, the use of internal orthopedic implants (plate and screws, for example) become the most suitable for osteosynthesis...

Background: The hip dislocation is the most common traumatic dislocation in dogs. Surgical treatment has better results, but there is still no consensus on the best technique. This study aims to report a case of traumatic hip dislocation in a dog, in which case it was decided by extra-articular stabilization, using absorbable monofilament wire of Polydioxanone, through implementing the Ilium-Femoral Suture Technique. This surgical thread is composed of a poly dioxanone polymer and differs from polyglycolic acid and polyglactin 910 by being a monofilament. The surgical technique consists of making a tunnel in the ileum body, in dorsolateral-ventromedial direction and another in the greater trochanter, in the caudally skull. The stabilization is achieved using one or more sutures standard 8, passing through the two tunnels. The vast majority of published works on the subject, reports the use of non-absorbable wires, such as surgical nylon or polyamide in the making of this type of suture, justifying the relevance of this report. Case: A Belgian Malinois breed dog of 2.5-year-old, female, was treated at a private clinic in the city of Porto Alegre, RS, Brazil, with trauma history by trampling. The patient had lack of member support and maintenance of the same in external rotation. General anesthesia of the patient, with 5 mg.kg-1 of Propofol (Propovan®), preceded by the [...]

The objective of this study was to investigate the bone regeneration of a "gold standard" (autograft) from iliac crest associated with cellular therapy in rabbits. A bone defect was created with 10x5x5mm in 28 rabbit mandibles. The control group animals (n=14) were repaired with autograft of iliac crest and the experimental group animals (n=14) received iliac crest autograft in association with mononuclear cells from the bone marrow of the femur. Weekly radiographs were taken of the surgery region and histological analyses was performed in seven animals in each group at 15 days and in seven animals of each group at 30 days after the surgery. A gradual increase of bone density was observed and the experimental animals presented the bone bridge in 85.7 percent (6/7) of the cases, while only 42.8 percent (3/7) of the animals in the control group presented this structure 28 days after the surgery. The histopathological parameters analyzed did not show any statistical difference between the control and experimental group in 15 and 30 days of analysis. The results suggest that the mononuclear cells from the marrow bone can better support the autograft regeneration in mandible defects in rabbits.(AU)
Avaliou-se a regeneração óssea de auto-enxerto, considerado "padrão ouro" da crista ilíaca associado à terapia celular da medula óssea em coelhos. Foi criado um defeito ósseo de 10x5x5mm na mandíbula de 28 coelhos, distribuídos em grupo-controle com, 14 animais, reparados com auto-enxerto de crista ilíaca, e grupo experimental com, 14 animais, em que o auto-enxerto foi associado a células mononucleares da medula óssea autógena do fêmur. Foram realizadas radiografias semanais da região operada e análise histológica em sete animais de cada grupo aos 15 e em sete de cada grupo aos 30 dias do pós-operatório. Houve aumento gradativo da densidade óssea, e 85,7 por cento (6/7) dos animais do grupo experimental e 42,8 por cento (3/7) do grupo-controle apresentaram formação de ponte óssea 28 dias após a cirurgia. Na análise histopatológica aos 15 dias, os enxertos foram facilmente visualizados e a atividade das células fagocitárias foi intensa. Já aos 30 dias, a visualização foi mais difícil e, quando possível, apenas um resquício foi visualizado. Os resultados sugerem que a adição de células mononucleares da medula óssea favorece a regeneração do auto-enxerto em defeitos mandibulares de coelhos.(AU)
