ABSTRACT

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)

ABSTRACT

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)


Na medicina veterinária, a terapia celular ainda é inexplorada e há muitas perguntas não respondidas, o que leva os pesquisadores a uma tendência a estender a terapia para os seres humanos, na tentativa de tratar certas lesões. Investigar esse assunto em primatas não humanos revela-se uma oportunidade sem precedentes para compreender melhor a dinâmica das células-tronco contra algumas doenças. Assim, objetivou-se comparar a eficiência das células mononucleares de medula óssea (BMMCs) e das células-tronco mesenquimais (MSCs) do tecido adiposo de Chlorocebus aetiops na lesão óssea induzida. 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)

ABSTRACT

Avulsion fractures of the apophysis of the iliac crest have rare incidence and are little known. In this article, we report the case of an 11-year-old female patient who presented this injury after indirect trauma. From careful radiographic analysis, an avulsion fracture of the iliac crest was identified. It was decided to use nonsurgical treatment comprising analgesia and load restriction. This case report emphasizes the importance of suspecting avulsion fractures in cases of low-energy trauma, and also guides the treatment, so as to prevent functional deficit and deformities...


A fratura avulsão da apófise da crista ilíaca apresenta incidência rara e pouco conhecida. Neste artigo relatamos caso de paciente do sexo feminino, de 11 anos, que apresentou essa lesão após trauma indireto. Após uma análise cuidadosa da radiografia, foi identificada fratura avulsão da crista ilíaca e optou-se pelo tratamento não cirúrgico com analgesia e restrição de carga. O relato do caso salienta a importância da suspeição da fratura avulsão em traumas de baixa energia, além de orientar o tratamento e prevenir déficit funcional e deformidades...

ABSTRACT

Las fracturas de pelvis en pacientes pediátricos son muy poco frecuentes y representan entre 1% a 3% de todas las fracturas pediátricas. Se asocian con traumatismos de muy alta energía, accidentes automovilísticos y otras lesiones potencialmente fatales. Se realizó un estudio prospectivo, analítico, observacional, de cohorte hospitalaria donde se incluyen todos los pacientes de ambos sexos, con edad inferior o igual a 15 años tratados quirúrgicamente en el Instituto Autónomo Hospital Universitario de los Andes en Mérida, Venezuela, de enero 2005 a enero de 2010. Se encontraron 25 pacientes, 52% de sexo femenino. La edad promedio fue de 9,4 años. El tiempo promedio del seguimiento fue de 43 meses. En 76% la causa fue accidente por vehículo automotor. El patrón de fractura más frecuente fue Tipo IV de Zorode y Zieg, en 88%. Se encontraron lesiones asociadas en 92%, una tasa de mortalidad del 12% e infección en 8%. Las principales complicaciones encontradas fueron la asimetría pélvica. El protocolo de manejo de estas lesiones debe incluir el diagnóstico y clasificación temprana, estabilización y evaluación de acuerdo al ATLS, manejo de las lesiones asociadas y estabilización quirúrgica de las fracturas para evitar asimetría y pobres resultados funcionales(AU)


Pelvic fractures in pediatric patients are rare, accounting for 1% to 3% of all pediatric fractures. They are associated with high energy trauma, car accidents and other life-threatening injuries. We performed a prospective, observational, analytical and hospital cohort. We included all patients of both sexes, aged up to 15 years old treated in the University Hospital Institute of the Andes in Merida, Venezuela, from january 2005 to january 2010. They found 25 patients, 52% were female. The average age was 9.4 years. The mean follow up time was 43 months. In 76% the cause was motor vehicle accident. The most common fracture pattern was Type IV Zorode and Zieg at 88%. Associated lesions were found in 92% patients. The mortality rate 12% and infection was 8%. The main complications were pelvic asymmetry. The protocol for management of these lesions should include early diagnosis and classification, stabilization and evaluation according to ATLS management of associated injuries and surgical stabilization of fractures to avoid asymmetry and poor functional outcomes(AU)

ABSTRACT

OBJETIVO: Avaliar a segurança do uso de fixação iliosacral com parafusos em pacientes com lesão do anel pélvico. MÉTODOS: Trata-se de um trabalho restrospectivo analisando por tomografia computadorizada a topografia de 60 parafusos inseridos em 46 pacientes portadores de lesões do anel pélvico e operados no INTO-RJ, no período de 2006 e 2010. RESULTADOS: Em 21,7 por cento dos casos o parafuso encontrava-se fora do corredor de segurança descrito em literatura. Destes, 77 por cento estavam associados a uma redução insatisfatória do anel pélvico. Não houve casos de lesão neurovascular em nossa série. CONCLUSÃO: O uso de parafusos ílio-sacrais é uma técnica segura, pois mesmo em casos onde o parafuso não respeitou uma topografia ideal, não houve complicações significativas associadas a este método. A má redução do anel pélvico é um fator muito importante associado ao mau posicionamento dos parafusos.


OBJECTIVE: To evaluate the safety of iliosacral screw fixation in pelvic injuries. METHODS: A retrospective study based on computer tomography evaluation of screw topography and its relationship with the so called pelvic safe corridor. RESULTS: We evaluated the topography of 60 screws inserted in 46 patients sustaining pelvic injuries which were operated in the INTO from 2006 to 2010. In 21.7 percent of cases the screw was located outside the safe corridor. 77 percent of these misplaced screws were associated with an unsatisfactory reduction of the pelvic injury. CONCLUSIONS: In our study, a significant rate of misplaced screws in relationship with the safe corridor has been pointed out and in most of these cases an insufficient reduction of the pelvis was also identified. We conclude that iliosacral fixation is a safe adjuvant method for pelvic fixation since in our series even with a relative high incidence of misplacements, no neurovascular injuries have been recorded in association with this technique.

ABSTRACT

Anterior iliac crest is the most common donor site for anterior cervical spine surgeries. We searched the literature to summarize the reported fractures of the anterior iliac crest following bone graft harvesting for anterior cervical fusion and documented our experience with such complication. In this account, we report 3 new patients with this rare complication of fracture of the anterior iliac crest following bone graft for anterior cervical fusion. The dual energy x-ray absorptiometry scan was performed in all our patients to assess bone mineral density and all patients had osteoporosis. Non-operative treatment was the method of treatment in our patients. A better understanding of surgical technique and complications of iliac crest bone grafting is important to minimize graft site morbidity, and even more important is identification of risk factors that are involved in fracture of the iliac crest
