Micropartículas de PLLA y CHT como andamiaje para la regeneración del cartílago articular: Modelo animal.
espanolLa naturaleza avascular del cartilago ha supuesto que historicamente las lesiones osteocondrales hayan tenido mal pronostico. Una de las opciones de tratamiento para dichas lesiones es el uso de andamiajes, siendo superior respecto a otras tecnicas que consiguen un fibrocartilago como resultado. Hemos elaborado microesferas de PLLA y CHT para usarlos como andamiaje en lesiones osteocondrales producidas a conejos albinos New Zealand. Se distribuyeron grupos con diferentes proporciones de microesferas, asi como un grupo control con la lesion sin tratar. Se analizo tambien el cartilago nativo de la rodilla contralateral. Se evaluaron las muestras para establecer la calidad del cartilago…
Chondrocostal grafting for lateral osteochondral injury of the metacarpal head
Abstract Osteochondral injuries of the metacarpal head require anatomical restoration to prevent limitations in range of motion and osteoarthritis. Osteochondral bone grafting is a viable option, especially in younger patients. Central injuries allow for different types of grafting, but when the injured area is on the lateral portion of the metacarpal head, the graft must include both a cortical and a cartilaginous portion. We present here the pearls and pitfalls in the surgical technique of chondrocostal grating from the 6th rib and an example of its use within a case of comminuted fracture of the metacarpal head. This technique provides a graft with cortical bone that allows for a stable …
