[Radiation-sparing intramedullary nailing with a radiolucent drilling system].

The indications for intramedullary fixation of tibial and femoral shaft fractures markedly increased by the introduction of interlocking techniques. Distal interlocking however remains a major problem although a variety of different aiming devices have been proposed. To reduce the radiation exposure both of the surgeon and the patient the AO has produced a radiolucent drive which allows easy aiming and drilling with a minimum of X-ray exposure.
