Abstract
A compression device made of a superelastic material having a peripheral portion with an upper surface, a lower surface, and a central opening extending therethrough is provided. Tips of one or more resilient structures of the compression device project inward of the peripheral portion and form an opening. The one or more resilient structures are configured to exert a biasing force in a direction when deformed in an opposite direction. Also provided is a bone plate assembly comprising a captively retained compression device and a bone plate comprising one or more integrally formed resilient structures.
Claims9
A bone plate assembly comprising:
- a compression device comprising a peripheral portion, an upper surface, a lower surface, an opening, and a plurality of inwardly projecting resilient teeth, individual teeth of the plurality of teeth having tip portions that extend distally beyond the lower surface of the peripheral portion, the teeth configured to apply a compressive force having a substantial axial component when displaced, wherein the compression device comprises a material that is superelastic at human body temperatures;
- a bone plate comprising a plate body including an upper plate surface, a lower plate surface, an aperture through the plate body, and a countersunk region open to the upper plate surface and formed about the aperture, the countersunk region comprising an intermediate seat region sized to seat the compression device, the compression device being captively retained within said countersunk region.
