Cerclage wire positioning insert
First Claim
1. A bone fracture stabilization apparatus comprising:
- at elongated bone plate having a plurality of apertures in the form of an elongated slot with rounded ends extending through said bone plate;
at least one insert having a body shaped for insertion into at least one of said plurality of apertures in said bone plate, said body having a flange extending from said body for engaging an outer surface of said bone plate and a boss extending from said body in a direction away from the fractured bone, said boss having at least one opening therein;
a cable extending through said opening in said boss and around the fractured bone; and
a means for fixing the length of cable after said cable has been tensioned around the bone to hold the bone plate in engagement with the fractured bone.

Abstract
A bone fracture stabilization apparatus includes a cable positioning insert for a bone plate of the type having a series of apertures therein for receiving bone screws for attaching the bone plate to the bone. The cable positioning insert has a body shaped for at least partial insertion into at least one of the apertures of the bone plate. The insert further includes a flange extending from the body for engaging either the outer or inward surface of the bone plate. A boss extends from the body in a direction away from the bone when the bone plate is mounted thereon. The boss has at least one opening and preferably two openings therein for accommodating a cerclage cable and positioning it relative to the apertures in the bone. The boss may be made of a malleable material that deforms under pressure to flatten the openings therein and capture the cable.
