    摘要: An implant insertion assembly including an insertion handle extending from a proximal end to a distal end, the distal end including a recessed portion, an outer wall of the recessed portion having a first shape about a perimeter thereof and including an engagement mechanism. The implant insertion assembly also includes an implant extending from a distal end to a proximal end including an opening configured to receive the recessed portion of the insertion handle, the opening having a second shape configured to mechanically interlock with the outer wall of the recessed portion when the recessed portion is inserted therein to transmit torque from the insertion handle to the implant, the proximal end including a receiving structure in a wall thereof, the receiving structure being positioned and oriented to receive the engagement mechanism to removably lock the insertion handle to the implant in the axial direction.

    摘要: A bone screw removal device includes a shaft extending longitudinally from a proximal end to a distal removal tip. The removal tip includes a first portion at a distal-most end of the removal tip, a second portion extending proximally from the first portion and a third portion extending proximally from the second portion. The first portion is sized and shaped to be received within a retaining recess of a bone screw to clear away tissue growth as the first portion is inserted through a driving recess of a bone screw and into the retaining recess. The second portion is configured to be received within a driving recess. The third portion is configured to clear away tissue growth over a proximal end of the bone screw as the first and second portions are inserted into the retaining recess and the driving recess, respectively.

    摘要: A novel coplanar X-ray guided method and device for insertion of distal locking screws in intramedullary bone nails. The device has coplanar holes, which allow insertion of protective sleeves. A drill and bone screws can be inserted through the protective sleeves. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam need not be coaxial with the intramedullary nail holes. The aiming arm has a mobile portion and a fixed portion fastened to the nail, wherein said aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail after implantation. Once the aiming arm is precisely positioned, the aiming arm transverse holes and intramedullary nail holes are accurately aligned, protective sleeves are inserted through aiming arm holes, bone drills are drilled through the intramedullary nail holes and surrounding bone material, and bone screws are inserted, locking the intramedullary nail to the bone.
