Background:Hip fracture is one of the most common causes of care and hospitalization of older adults in the traumatology service, being considered in the present a public health problem because it causes orthopedic injury, decreased functional capacity, high rate morbidity, in-hospital complications and increased mortality.Objectives:Evaluate the epidemiological behavior of patients with fracture of hip admitted to the Hospital Universitario de los Andes in Merida, Venezuela, during the period 2012-2015.Methods:Descriptive retrospective study in patients with a diagnosis of hip fracture admitted to the Hospital Universitario de Los Andes in Merida, Venezuela during the period between 01/01/2012 to 12/31/2015. Cases were defined as patients older than 20 years old, hospitalized with a diagnosis of hip fracture, femur neck fracture, pertrochanteric fracture and subtrochanteric fracture. The data obtained specifically for this analysis were: sex, age, year of admission, days of stay in-hospital and hip fracture subtype. The quantitative variables are presented in mean±standard deviation, compared using the One-way ANOVA test. Results were considered statistically significant when p<0.05.Results:The total number of patients with hip fracture evaluated was 1050, age average was 75.3±18.2 years, with female predominance (67.3%; n=707). Fracture of the neck of the femur was the most common type of fracture, with 68.7% (n=721), and a higher prevalence during 2012 (86.4%) and 2013 (91.2%). Meanwhile the pertrochanteric fracture was the second most frequent, predominating during 2014 (48.4%) and 2015 (47.9%)When evaluating factors related to the type of fracture, only age showed a statistically significant association, with a higher frequency of subtrochanteric fracture in the subjects <75 years (43.3%). Our findings correspond to previous reports indicating higher incidence of hip fractures in older women, but in younger men a higher frequency of hip fractures is present in the younger age group. The progressive increase in the incidence of hip fractures is mainly caused by aging, decreased bone strength and increased risk of falling related to age as well as the presence of osteoporosis. No differences were shown in the number of days of hospital stay.Table 4.Subject distribution according sex, age and fracture subtype.376Fracture subtypeFemur neck fracturePertrochanteric fractureSubtrochanteric Fracturen%n%n%χ2 (P)*Sex0,6(0,73)Feminine48266,918669,13965,0Masculine23933,18330,92135,0Age groups10,5(0,03)<75 years25134,87327,12643,3**75-85 years25235,09434,92033,3>85 years21830,210237,91423,4# of days in-hospital stay¶13,911,812,99,813,08,10,38Osteoporosis25235%9434.9%1423.4%0.29*Z of proportions: p<0.05*Chi Square** Z of proportions: p<0.05¶ Mean±deviation standard. Comparisons with ANOVA testConclusion:The prevalence of hip fracture cases in Venezuela is low compared to other regions of the world, with a predominance in women, in subjects older than 75 years and with involvement of the neck of the femur. However in younger patients, males and subtrochanteric fractures are more prevalent. In future studies, we recommend quantifying the target population to determine incidence rates, as well as the evaluation of other variables that allow specifying the prognosis and evolution of this group of patients.REFERENCES:[1] Muñoz S, Lavanderos J, Vilches L, Delgado M, Carcamo K et al.
