Objetivo: Establecer un modelo experimental reproducible, en el cordero, para provocar una necrosis avascular de la cabeza del fémur.<br/>Material y metodología: Utilizamos 21 corderos, con edades comprendidas entre los 6 y 22 semanas. En el primer grupo (13 corderos) se seccionó la musculatura ilio-inguinal, inyectando una sustancia esclerosante y ligando los vasos pericapsulares en el cuello femoral, mediante cerclaje de alambre. En el segundo grupo (9 corderos) se ligó el cuello femoral mediante brida de plástico y sección del ligamento redondo. No se utilizó ningún tipo de inmovilización. El sacrificio de los animales se realizó, según el grupo, entre las 15 y 34 semanas. Efectuamos estudios radiográficos, macroscópicos e histológicos.<br/>Resultados: Las cabezas femorales mostraron un centro secundario de osificación y un adelgazamiento del cartílago fisario, más intenso en los animales con evolución superior a 7 semanas tras el insulto vascular. Se observó un aumento de la densidad ósea de la cabeza femoral, con aplanamiento cefálico, disposición irregular de la fisis e hipercrecimiento del trocánter mayor. Hallamos necrosis del cartílago articular sin apreciar una invasión vascular de la zona hipertrófica del cartílago de crecimiento. En la metáfisis hallamos áreas fibróticas.<br/>Conclusión: La lesión vascular experimental en la cadera de corderos inmaduros produce cambios apreciables en el cartílago articular, el centro secundario de osificación, la fisis de crecimiento y la metafisis. <br/> |

Objective: To establish a reproducible experimental model in lambs to cause avascular necrosis of the femoral head.<br/>Material and Methods: We used 21 lambs, aged between 6 and 22 weeks. In the first group (13 lambs), the ilioinguinal musculature was sectioned, injecting a sclerosing substance and ligating the pericapsular vessels in the femoral neck by wire cerclage. In the second group (9 lambs), the femoral neck was ligated using a plastic loop and sectioning of the round ligament. No type of immobilization was used. The animals were sacrificed, depending on the group, between 15 and 34 weeks. We conducted radiographic, gross, and histological studies.<br/>Results: The femoral heads showed a secondary site of ossification and thinning of growth plate cartilage, more severe in the animals with course longer than 7 weeks after vascular injury. Increased bone density in the femoral head, with cephalic flattening, irregular arrangement of the physis and hypergrowth of the greater trochanter was observed. We found necrosis of joint cartilage without evidence of vascular invasion.<br/>of the hypertrophic area of cartilage growth. We found fibrotic areas in the metaphysis.<br/>Conclusion: Experimental vascular injury in the hip of immature lambs causes substantial changes in joint cartilage, the secondary site of ossification, the growth physis and metaphysis. |
