摘要
A mobile dynamic implantable spinal apparatus (10) comprising at least one fixed bracket (16a) secured on a correcting rod (12) and at least one mobile carrier (18a) slidably mounted on the correcting rod (12). The fixed bracket (16a) and the mobile carrier (18a) each include a body and a pedicle screw (20) or a transverse process hook articulated to the body. The distribution of the degrees of freedom between the carrier (18a) and the rod (12), and the pedicle screws (20) or hooks and the carrier (18a) and the fixed bracket (16a) provide a non-rigid assembly which preserves some of the natural mobility of the vertebrae and disk, and the potential growth of the spinal column.
