ABSTRACT

São poucos os dados publicados sobre a aplicabilidade ou a confiabilidade dos métodos digitais para mensuração do ângulo do platô tibial (APT) em comparação à mensuração manual. O objetivo deste estudo foi comparar o APT obtido pelo cálculo manual padrão, em filmes radiográficos, com os valores obtidos por cálculos em imagens digitais, por meio do software do computador. Foram analisadas radiografias digitais do membro pélvico, direito e esquerdo, em perfil verdadeiro, de 20 cães saudáveis, com idade superior a um ano. Três observadores com graus de experiência semelhantes em cálculo do APT realizaram as mensurações em cada radiografia. Primeiramente, foram calculados os ângulos dos platôs tibiais manualmente nas películas radiográficas e, posteriormente, os cálculos foram realizados na imagem digital, por meio do software para medicina veterinária do sistema de raios X digital. Os resultados do presente estudo demonstraram diferenças significativas entre os métodos, com valor das médias do cálculo digital 20,48±3.71 e do cálculo manual 23.90±4.02. Valor de P foi < 0,01 na comparação entre médias dos dois grupos. Na avaliação interobservadores, houve diferença significativa no cálculo manual no perfil direito, o que sugere maior variação no cálculo manual quando comparado ao digital. O cálculo realizado pelo software apresentou menor variação nos valores interobservadores. Acredita-se que a menor variação obtida nos resultados aqui apresentados se dê em razão das facilidades proporcionadas pelo software. Conclui-se que houve diferença entre os valores obtidos por meio dos métodos convencional e digital no cálculo do ângulo do platô tibial, sendo os valores digitais menores entre os observadores, e que o método digital no cálculo do ângulo do platô tibial levou à menor variação quando comparado ao método manual.(AU)


There are few published data on the applicability and reliability of digital methods for measuring the TPA compared with manual measurement. The objective of this study was to compare the TPA obtained by calculating standard manual on conventional radiographs, with the values obtained by calculations in digital images through a computer program. Bilateral digital radiographs of hind limb were analyzed in true profile for 20 healthy dogs older than two years. Three observers with similar levels of experience in calculating the TPA conducted measurements on each radiograph. First we calculated the angle of the tibial plateaus manually in x-ray film and then the calculations were made through the program offered by the computer program in the digital image. The results of this study showed significant differences between the methods, with average value of 20.48±3.71 digital calculating average and 23.90±2.4 in the manual calculation. P value was < 0.01 when comparing averages. No significant difference in manual calculation in right profile were found between interobserver assessments, suggesting greater variation in manual calculation compared to digital. The calculation performed by the software showed less variation in values. The slight variation obtained in our results is believed to be due to the facilities provided by the software. There was a difference between the values obtained by means of conventional and digital methods for calculating the angle of the tibial plateau, and the smaller digital values between the observers and the digital method in the calculation of the tibial plateau angle led to less variation when compared to the manual method.(AU)

ABSTRACT

Estamos reportando cuatro casos de ausencia congénita del ligamento cruzado anterior de la rodilla, documentados a lo largo de 10 años de práctica en cirugía artroscópica. Todos los pacientes, un hombre con ausencia congénita bilateral, y dos mujeres, completamente sanos, sin evidencia de alguna otra alteración congénita; que realizan sus actividades completamente normales, incluidas la práctica de algún deporte. Todos ellos han cursado con datos clínicos de inestabilidad, sin lesión previa alguna, la inestabilidad en el caso de las mujeres ha correspondido a un grado I en el signo de cajón anterior y no ameritó manejo específico. En el caso del hombre, la inestabilidad de la rodilla derecha era considerable (cajón anterior 10 mm) por lo que se realizó plastía modificada de Jones. En la rodilla izquierda la inestabilidad es mínima y no se efectuó manejo quirúrgico. En todos los pacientes se corroboró artroscópicamente la presencia del ligamento cruzado posterior sin daño, en el último caso, una joven de 23 años, incluso nos llamó la atención su fuerte tensión. Radiográficamente, en dos pacientes encontramos cambios de osteoartrosis mínimos, y en la última paciente, con rodilla sin datos de artrosis tanto por radiología como a la vista artroscópica.

ABSTRACT

This study is based on 49 patients with chronic anterior cruciate ligament [ACL] deficiency who had ACL reconstruction using free patellar tendon graft. Its main objective was to compare the results of ACL reconstruction done by arthroscopy and with that done by mini arthrotomy. Patients were 37 males and 12 females; their average age was 25 years [range 17 to 37 years]. 1 female had bilateral ACL reconstruction. The patients were divided into two groups: Group /: had undergone the arthroscopic procedure and Group II: had mini arthrotomy. Our results showed that mini arthrotomy patients [Group I], as compared to Group II, had longer hospital stay, had delay in resuming sport activity and had longer sick leave; however, there was no significant difference in the final outcome between both procedures. This, in addition to the high cost and fragility of arthroscopic material led us to recommend mini arthrotomy as the procedure of choice for ACL reconstruction
