Jig with guide adapted to lock relative to both of threaded holes and non-threaded slots in a bone plate

Abstract

A system, devices and methods arc provided for facilitating stabilization of periarticular fractures. The system includes a compression plate and one or more of a cerclage cable for encircling the bone and securing the compression plate to the bone, a crimp lug for securing the cable in tension relative to the bone and/or a plate, and a supplemental plate coupled to the compression plate and adapted to receive bicortical or unicortical bone screws to further secure the compression plate relative to the bone. In addition, the system includes a cable tensioner for temporarily retaining the cable in tension and then applying a tension to the cable until a desired compression is effected between a plate and bone and while a cable retaining structure is secured to the cable to retain the applied tension on the cable. Also provided is a jig for use with plates for minimally invasive fracture stabilization.

What is claimed is: 
     
         1 . A jig kit for inserting screw into a bone plate, the bone plate having an upper surface and a lower surface, a plurality of spaced apart screw holes extending between the upper and lower surfaces, the screw holes including circular threaded screw holes for receiving fixed angle bone screws and elongate compression screw holes for receiving compression bone screws, comprising:
 a) a jig including a jig arm having a plurality of spaced apart threaded jig holes at a same center-to-center spacing as the screw holes of the bone plate, and a jig base that couples to the bone plate and spaces the jig arm relative to the bone plate;   b) a locking element to lock said jig relative to the bone plate;   c) an outer sleeve receivable within a respective jig hole, and having a proximal threaded end that threadedly engages with the respective jig hole, and a length sufficient to extend from said jig arm to adjacent an upper surface of the bone plate; and   d) a drill guide insertable through said outer sleeve and into stable engagement with either of the threaded screw holes or the compression slots of the bone plate so as to retain said drill guide relative to the respective screw hole.
