A controlled removable fracture-reducing assembly (10) for reducing a bone fracture. According to one embodiment of the present invention, a controlled removable fracture reducing assembly (10) includes an implant (12), a reducer (14), a buttress (16), and a locking device (18) that engage a proximal bone fragment (2) and a distal bone fragment (4). The implant (12) is secured to the distal bone fragment (4) by the locking device (18). The buttress (16) engages the implant (12) through an opening (30). The reducer (14) contains a compressing screw (24) that applies a force (60) on the buttress (16), reducing the fracture. According to another embodiment of the invention, the reducer (114) contains a cam mechanism (124) which applies a force (186) on the buttress (116), which does not engage the implant (112), that pushes the proximal bone fragment (102) to reduce the fracture. According to another embodiment of the invention, the reducer (214) is a jacking mechanism that pushes the proximal bone fragment (202) while pulling the implant (212) and distal fragment (204) to reduce the fracture. |
