    摘要： Methods and devices are provided for passively locking a bone screw within a bone plate. In particular, the methods and devices allow a bone screw to be locked within a thru-hole in a bone plate without requiring any additional locking steps. In an exemplary embodiment, an annular feature is provided in a thru-hole of a bone plate, or in a bushing that is disposed within a thru-hole of a bone plate, for engaging a bone screw. The annular feature can be configured such that it allows the bone screw to be inserted through the thru-hole at various insertion angles while still being effective to prevent back-out of the bone screw, thereby locking the screw to the plate.

    摘要： Various methods and devices are provided for tensioning a tether. In one embodiment, a tether tensioning device is provided and includes a tensioning mechanism adapted to couple to a tether extending along a path between at least two bone anchors implanted in adjacent vertebrae. The tensioning mechanism can be adapted to apply a tensioning force to the tether along the path of the tether to thereby move the tether along the path. The device further includes an actuation mechanism movably coupled to the tensioning mechanism such that the actuation mechanism is adapted to effect movement of the tensioning mechanism to control the tensioning force applied to the tether.

    摘要： A vertebral implant is provided that includes a distraction member having a first end configured to pivotally couple to a first cut portion of a vertebra and a second end configured to mate with a base member configured to couple to a second cut portion of the vertebra. The distraction member can move relative to the base member to create a force effective to adjust a distance between the first and second cut portions of the vertebra.
