Method: The aim of this retrospectively study was to ascertain trends in the incidence of hip fracture, resulting from traumas of low intensity (fall of same high), in age over 50 years old, using register information from University Hospital of Los Andes (Merida Venezuela) theatre records. There was a total of 404 fractures of the proximal femur, which affected 293 women’s and 111 men’s, the overall female:male ratio was 2.64:1. The average standardized incidence per 100 000 population per year was estimated.

Results: The mean standardized female incidence was 68.4/100 000 and male’s 47.0/100 000 inhabitant. Trochanteric fractures affect 73% of patients and the femoral neck fractures 27% of the patients (ratio 2.7:1). The case numbers increases sixfold, exponentially with age groups between 50 and more than 80 years, to go from 36 to 204 cases, and when we analyzed the incidence by the aged population is more evident to female trochanter fractures. According sex trochanteric fractures affects more women in a ratio of 2.5:1 and in the same way to the neck cervical 3.0:1. According to age, trochanteric fractures in women with a mean age of 80.8 and 74.8 years for men and femoral neck fractures 78.8 and 73.7 years respectively. If the stability criteria are used, stable fractures occurred in 30% of cases and unstable fractures in 70% of them.

Conclusions: In Merida (Venezuela) the hip fractures in older 50 years, affect more ladies (2.64:1). Mean age 78.7 years old. Between 50 and more than 80 years old the hip fractures increase sixfold, specially the female trochanteric fractures.
