Abstract
An apparatus and technique for infernally securing a plurality of bone segments together. The device incorporates a plate-like structure stabilizing the fracture and integrated fasteners to attach straps circumscribing the bone segments.
Claims9
A bone plate assembly, comprising:
- a plate having a plurality of apertures formed through the full thickness of the plate, with at least two of the plurality of apertures being positioned proximal to lateral edges on opposing sides of the plate;
- one or more fasteners each having a first end that is a leading end, and a second end opposite the leading end, each fastener being configured for the leading end to pass substantially around a portion of bone and through at least one of the apertures for locking engagement to establish compression with adjustable tension between the plate and the bone;
- a plurality of fastener attachments, each being incorporated with one of the apertures, with at least one of the fastener attachments being configured to allow the leading end of one of the fasteners to pass through one of the apertures in a first direction, and to resist fastener movement in a second direction opposite the first direction;
- each fastener attachment further comprising a base slot that accommodates entry of the fastener leading end into the fastener attachment to accept and secure the fastener attachment, and an exit slot through which the fastener leading end exits the fastener attachment;
- and
- further comprising at least one locking nut configured to be positioned over at least one of the apertures and having a hollow core through which a leading end of the fastener freely passes in the first direction, and wherein the fastener comprises ribs configured to engage an interior surface of the hollow core, thereby resisting movement of the fastener in the direction opposite the first direction.

- and
- further comprising a toothed locking tab allowing a leading end of the fastener to pass freely in the first direction, wherein the locking tab teeth are configured to press a portion of the fastener against a surface of the plate to resist movement of the fastener in the direction opposite the first direction.
