ABSTRACT:
Apparatus and methods for detecting the location of transverse holes of an intramedullary nail which has been inserted into a long bone and for aligning a surgical drill to the transverse holes. An insert having a light source at its distal end emitting non-ionizing electromagnetic radiation in the visible spectrum or infrared is inserted into the intramedullary nail, such that the light source is placed adjacent to the transverse holes. The light source may be a directional radiation output emitting the radiation in a direction perpendicular to the axis of the intramedullary nail. The light source may alternatively be an isotropic radiation output emitting radiation in all directions. The surgeon detects the transmitted radiation on the surface of the body of the patient and aligns the drill with the emitted radiation.
