Abstract
The present invention provides a bone plate that includes a sliding mechanism that allows for both static and dynamic loading and the associated stabilization or partial or whole immobilization of two or more adjacent bone fragments or vertebral bodies of the spine. This sliding mechanism is designed such that as bone resorbs or the like, the sliding mechanism maintains axial compression in a collinear manner across the bone segments.
Claims23
A bone plate incorporating a compression mechanism, comprising:
- a plate structure defining a plurality of screw receiving plate holes and a plurality of screw receiving plate slots;
- and
- a carriage assembly engaging the plurality of screw receiving plate slots, wherein the carriage assembly translates axially with respect to the plate structure via the plurality of screw receiving plate slots, thereby providing the compression mechanism.
A bone plate incorporating a compression mechanism, comprising:
- a plate structure defining a plurality of screw receiving plate holes and a plurality of screw receiving plate slots;
- and
- a carriage assembly engaging the plurality of screw receiving plate slots, wherein the carriage assembly translates axially with respect to the plate structure via the plurality of screw receiving plate slots, thereby providing the compression mechanism;
- wherein the plate structure is secured to a first bony structure using a plurality of screws;
- wherein the carriage assembly is secured to a second bony structure using a plurality of screws;
- and
- wherein the engagement of the plate structure and the carriage assembly provides dynamic compression between the first bony structure and the second bony structure.
