System and method for retaining screws relative to a vertebral plate |
摘要 |
Devices and methods for maintaining the position of a screw relative to a vertebral plate. The device includes a plate having one or more screw holes each sized to receive a screw for attaching the plate to the vertebral member(s). A cap may be movably coupled to the plate. In one position the cap may overlap into the screw hole for receiving the bone screw. The bone screw may be inserted into the screw hole and mounted into the bone with the cap overlapping into the screw hole. In one embodiment the screw moves past the cap and may be captured beyond the cap preventing back-out of the screw. The cap may also be moved to a second position to allow for removal of the bone screw from the vertebral member.
