Resumen (ES)

Twenty six comminuted and rotationally unstable fractures of the femur were treated
with the FMBP intramedullary locked nail. Twenty two of the fractures had comminution involving
more than 50% of the cortex. Of the nailings, 22 were static and 4 dynamic. Clinical and
radiographic union occurred in 92% of cases. There were 2 nonunions. There was one case of deep
wound infection. Only one patient had a shortening greater than 1 cm. Angulation in any plane
greater than 10° was noted in 5 patients. There were no instances of rotatory deformities. The interlocking
nail has expanded the indications for the use of closed intramedullary nailing in the treatment
of unstable femoral fractures. The incidence of infection and nonunion is low. Stability of
the fractures allows immediate mobilization of the patients, early rehabilitation of the limb and
shorter hospital stay. The FMRP nail eliminated fluoroscopy, flexible reamers and is cheaper as
compared to other systems.
