Hueso metacarpiano [III]
Os metacarpale [III]
Definición
El Hueso Tercer Metacarpiano (os metacarpale III; hueso metacarpiano del dedo medio) es ligeramente más pequeño que el segundo.
La cara dorsal de su base presenta en su lado radial una eminencia piramidal, la apófisis estiloides, que se extiende hacia arriba por detrás del hueso grande; inmediatamente distal a esta se encuentra una superficie rugosa para la inserción del extensor radial corto del carpo. La faceta articular carpiana es cóncava en su parte posterior, plana en su parte anterior, y se articula con el hueso grande. En el lado radial hay una faceta lisa y cóncava para la articulación con el segundo hueso metacarpiano, y en el lado ulnar dos pequeñas facetas ovales para el cuarto hueso metacarpiano.
