<p>H /txb/Intenvove/NRPortb]/DCC/TXB/5851203_I.DOC -27/11113 A controlled removable fracture-reducing assembly for reducing a bone fracture. According to one embodiment of the present invention, a controlled removable fracture reducing assembly includes an implant, a reducer, a buttress, and a locking device that engage a proximal bone fragment and a distal bone fragment. The implant is secured to the distal bone fragment by the locking device. The buttress engages the implant through an opening. The reducer contains a compressing screw that applies a force on the buttress, reducing the fracture. According to another embodiment of the invention, the reducer contains a cam mechanism which applies a force on the buttress, which does not engage the implant, that pushes the proximal bone fragment to reduce the fracture. According to another embodiment of the invention, the reducer is a jacking mechanism that pushes the proximal bone fragment while pulling the implant and distal fragment to reduce the fracture.</p> |
