Abstract

A system for fixating a bone includes a buckle having a plurality of lock bars and a hook. A cord may connect the hook with an opposite end of the buckle and around a bone. The buckle may include lock bars on the opposite end of the buckle to receive the cord and allow a frictional resistance to a loosening of the cord around the bone to facilitate a reduction of a fracture of the bone.

First claim

We claim:

1. A fracture fixation system comprising: a connector having a proximal end for connecting to a first end of a cord configured to extend around a bone to provide fixation to a fracture of the bone, said proximal end comprising a plurality of lock bars bounding slots for engaging the cord to tighten the cord to provide the fixation of the fracture; said connector having a distal connecting end opposite said connector relative to said proximal end for attaching to a second end of said cord extending around the bone; said distal connecting end comprising a hook or loop; and said fracture fixation system further comprises a tensioner engaged with slots on opposite longitudinal sides of said connector to hold said connector to allow a user to provide tension to the cord to fixate the fracture, wherein said slots on opposite longitudinal sides of said connector are aligned longitudinally relative to the connector and are configured to engage arms of said tensioner.

2. The system of claim 1 wherein said tensioner comprises a handle connected to a rod having a passage to receive the cord such that a rotation of the handle provides a tension on the cord to fixate the fracture.

3. The system of claim 1 wherein a first lock bar of said plurality of lock bars comprises a cross-sectional tear drop shape.

4. The system of claim 1 wherein the cord is threaded around the lock bars and tightened such that the cord is held at a particular tightness to allow the fixation of the fracture.
