    摘要: A system for guiding an implant to an optimal placement within a patient includes a trajectory guide for guiding instruments along a selected trajectory and a trajectory fixation device for fixing the trajectory guide in a selected position. The trajectory guide defines a path configured to align with the selected trajectory. A movable support mounts the trajectory guide and selectively moves the trajectory guide to align the trajectory guide with the selected trajectory prior to fixing the trajectory guide in the selected position. The trajectory is aligned coarsely by hand, then the trajectory is aligned using a fine adjustment system. After fixing the trajectory guide, instruments can be inserted along the trajectory through the path defined by the trajectory guide.

    摘要: A method of correcting spinal deformity, which includes locating pharmaceutical-loaded implants adjacent to targeted spinal growth plates, and then eluting the pharmaceutical onto the growth plates. Preferably, the method involves correcting spinal deformity by simply inserting a pharmaceutical-eluting pedicle screw onto the concave side of a scoliotic curve. The screw has a cannulated internal reservoir that contains a chondrocyte growth-inducing pharmaceutical (such as a growth factor or small molecule) and at least one fenestration that allows the pharmaceutical to elute onto the vertebral body growth plate.
