Abstract
A novel coplanar X-ray guided method and aiming arm device for insertion of distal locking screws in intramedullary bone nails. 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 nail holes. The aiming arm includes a mobile portion and a fixed portion fastened to the nail, and the aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail caused by implantation in bone.
