摘要: A flexible spinal fixation element is provided that is movable between a first position, in which the spinal fixation element is adapted to be angularly manipulated, and a second, locked position, in which the spinal fixation element is aligned in a desired orientation and is immovable. The configuration of the flexible spinal fixation element can vary, but the fixation element is preferably formed from a bioimplantable member having segments or a bellows configuration that allows the fixation element to be selectively configurable between the first and second positions. In use, the flexibility of the spinal fixation element allows the fixation element to be introduced through a percutaneous access device, thereby advantageously allowing the fixation element to be implanted using minimally invasive techniques.
