[Intramedullary nailing as an alternate method in the management of slow-healing or pseudarthrotic upper and lower leg fractures].

Intramedullary nailing of delayed healing fractures and non-unions in the lower extremity is the method of choice in biological and biomechanical aspects. With the technic of interlocking screws the indication is extended to the metaphyseal areas of tibia and femur. By nailing as alternative method an ossification of fractures and non-unions can be reached at a rate of about 90 per cent. This result is rather unique in the literature. In the treatment of shaft non-unions after cast fixation or rigid stabilisation by plates or external fixation nailing must succeed throughout its weight-bearing system and only fails in the case of infection and wrong indication.
