title: EPIDEMIOLOGICAL AND RADIOLOGICAL EVALUATION OF FEMORAL SHAFT FRACTURES: STUDY OF 200 CASES.
abstract: OBJECTIVE
  to evaluate epidemiological and radiological characteristics of the femoral shaft fractures, surgically treated from 1990 to 2005 at Hospital de Acidentados - Clínica Santa Isabel - in Goiânia, Goiás, aiming to contribute to better preventive and therapeutic measures planning to adopt on those fractures.
  
  
  METHODS
  200 patients' files and x-rays with femoral shaft fractures have been retrospectively evaluated. Patients below the age of 10 years were not included because the treatment for this group was conservative. 25 files have been discarded for not supplying all the necessary data to the study. The patients were assessed for sex, age, side of the fracture, bone exposure, mechanisms of trauma, classification of the fractures, associated trauma, time for bone healing and types of surgical devices. Statistic analyses were made by chi-squared, Fisher and Student's-t tests, adopting as a significance level p<0.05.
  
  
  RESULTS
  significant results (p < 0.05) were found in: 70% of men, 80% closed fractures and 65% of women above the age of 60. Fractures resulting from simple falls were more frequent in women, above 60 years old, with simpler traces, and the ones caused by projectiles of firearm in men, from 20 to 60 years, with unstable traces. Trampling accidents were prevalent among youngsters between 10 and 19 years old. Car accidents showed all the types of fractures, mostly associated to other traumas, reaching its peak incidence in the age group of 20-30 years. The treatment with Küntscher Nail resulted in a longer mean consolidation time, as well as fractures with unstable traces (B3,C1,C2,C3).
  
  
  CONCLUSIONS
  we found a bi-modal characteristic the femoral shaft fractures, consistently to literature data, where the high energy mechanisms (traffic accidents, high falls and wounds from firearms), have been more frequent in young adults, men, generating unstable traces of fractures, with more serious associated trauma, while the other group with low energy trauma (simple falls), was more frequently seen in elderly female individuals with less unstable fracture traces, without associated trauma.
