The invention relates to a system and method for driving orthopedic bone screws. In one aspect the driver includes a powered driving rod that is configured to releasably couple with a recess in a bone screw via a threaded system for coupling and uncoupling the screw from the driving rod.

Powered retaining screwdriver

An impacting device for inserting, positioning and/or removing an implant and/or performing other impacting applications. The impacting device may have a head having at least one recess. The recess may have a insertion channel and a locking chamber. In one embodiment, the insertion channel and the locking chamber may be connected by an axial channel. The recess may pass through a lateral surface of the head so that the base surface may remain cohesive or unobstructed. A guide means, such as a guide rod, may be positioned though the recess so that the head may be moveable on the guide means and not disengage the guide means. A shaft having a handle may be attached to the head to assist a surgeon in moving the head on the guide means.

Impacting device and method

An impacting device including a head having a longitudinal axis, a lateral surface and a base surface. The impacting device also includes a recess positioned in the head having a first channel and a second channel, the first and second channels being operably connected to each other. The first and second channels are at an angle with respect to each other when viewed in a plane parallel to the longitudinal axis.

The invention relates to an intramedullary nail () having a proximal half (), a distal half () adapted for insertion into the medullary canal, and a central axis (), whereby the distal half () includes three transverse bores () suitable for receiving locking screws (). The distal half () is provided with a proximal transverse bore () having a bore axis (), a central transverse bore () having a bore axis (), and a distal transverse bore () having a bore axis () spaced along the central axis (). The bore axis () of the central transverse bore (), which extends between the proximal transverse bore () and the distal transverse bore (), is spaced at a shortest distance 'a' from the bore axis () of the proximal transverse bore (), and at a shortest distance 'b' from the bore axis () of the distal transverse bore (), where a&#x2260;b.

Intramedullary nail

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.
