  • Patent number: 10172654
    Abstract: Systems, devices and methods are disclosed for limiting compression of a fracture imposed by a lag screw of a fixation system that includes a fixation device, a lag screw and a compression screw. The disclosed devices, systems and methods prevent over-compression of a fracture by a lag screw caused by over rotation of the compression screw. Specifically, implementations of a lag screw driver and a compression screw driver are provided whereby an engagement between the lag screw driver and compression screw driver prevents any further lateral movement of the lag screw, thereby providing a complete stop to further advancement of the lag screw and any additional compression.

  • Patent number: 8628532
    Abstract: A controlled removable fracture-reducing assembly for reducing a bone fracture. According to one embodiment, 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, 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, the reducer is a jacking mechanism that pushes the proximal bone fragment while pulling the implant and distal fragment to reduce the fracture.
