Uma série de 103 casos de fraturas diafisárias complexas do fêmur foram tratadas com a haste intramedular bloqueada FMRP, no período de maio de 1987 a dezembro 1995. Das 103 fraturas, 67 eram cominutivas, 12 bifocais (segmentar), 4 espirais, 13 proximais e 21 distais, instáveis, rotacionalmente, da diáfise femoral. Do total dos casos, constatou-se 97 bloqueios estáticos e 6 dinâmicos. Dessas 97 estáticas, 7 foram dinamizadas durante a evolução. Clínica e radiográficamente a consolidação ocorreu em 97,09% dos casos, com média de 16,72 semanas e em 3 casos não houve consolidação. Houve 4 casos de infecção suspeita e 3 estabelecidas que foram debeladas e evoluíram para consolidação. Houve 81 casos de encurtamentos que variaram entre 0,5 a 4 cm com média de 1 cm. O encurtamento menor ou igual a 2 cm ocorreu em 73 casos. Desvio de alinhamento em qualquer plano acima de 10 º e igual a 15º foi observado em 8 pacientes. Houve 10 casos de deformidades rotacionais, porém nenhum caso acima de 10º. A incidência de infecção foi baixa e a de consolidação alta. A estabilização dessas fraturas complexas permitiu imediata mobilização do paciente, reabilitação precoce do membro e diminuição da permanência hospitalar, excetuando os politraumatizados. A haste FMRP permitiu o tratamento dessas fraturas sem o uso de intensificador de imagens e de fresas flexíveis com baixo custo operacional. Os resultados foram semelhantes aos obtidos com as hastes intramedulares bloqueadas que necessitam de aparelhagem técnica mais sofisticada, porém com vantagens para o paciente e a equipe cirúrgica. A series of 103 cases of complex femoral fracture were treated with FMRP (Faculdade de Medicina de Ribeirão Preto) nail. These fractures were treated from May 1987 until December 1995. From the 103 fractures, 67 were cominutive, 12 bifocal (segmental), 4 spiral, 13 proximal e 21 distal and unstable rotationaly. From the total of cases, 97 were statically locked and 6 dynamic. From these 97, only 7 were dynamised during evolution. Clinical and radiographic union had occurred in 97.09 per cent of cases with average of 16.72 weeks. In 3 cases the union did not occur with interlocking nail. There were 4 cases with suspected and 3 with established infection that were healed by the time of evolution. There were 81 cases of shortening that varied from 0.5 centimeter to 4 centimeters with an average of 1.0 centimeter. The shortening of less than and equal 2 centimeters occurred in 73 cases. The alignment distortion in any plane up from 10 degrees and equal to 15 degrees was observed in 8 patients. There were 10 cases of rotational deformities, but no case above 10 degrees. The infection incidence was low; and, the union incidence was high. The fracture stabilization had immediately allowed patient's mobilization, early rehabilitation and decreasing hospital stay, except in politrauma cases. The FMRP nail had allowed treating these kind of fractures without using any image intensifier or flexible reamers. Hence this method had turned the cost of treatment down. The outcomes were matching to those reported with intramedullary interlocking nailing which needs technical equipment more sophisticated
