Abstract
A translaminar pedicle anchor suspension system (referred as T-PAS system) applicable to vertebral surgeries is disclosed. The T-PAS system comprises: at least one pedicle anchor capable of being fixed to a pedicle of a lower vertebral segment, at least one suspension ligament having one end thereof fixed to the pedicle anchor, and at least one washer capable of fixing the other end of the suspension ligament to a contralateral side of a lamina of an upper vertebral segment. By using the suspension ligament to suspend the upper vertebral segment via a tunnel drilled on the lamina, not only the spine can be dynamically stabilized, but also the use of traditional pedicle screws and bone fusion can be avoided.
