Objective: To assess the incidence and distribution of hip fractures by sex and age among individuals over 40 years in Lithuania in 2010.

Materials and methods: This population-based study was performed collecting the data from all orthopaedic-traumatology inpatient departments in Lithuania. The case histories of Lithuanian residents over 40 years, who had suffered a hip fracture in 2010, were examined. Subjects with primary hip fracture (ICD-10 codes S72.0, S72.1 and S72.2) were included. The incidence was calculated using the population data of Lithuania in 2010.

Results: Among 2518 subjects (76.4±11.64 years) included, 741 (29.4%) were men and 1777 (70.6%) women, resulting in a female to male rate ratio of 2.4. An average age was 68.8±13.3 in men and 79.2±9.6 in women. Hip fracture incidence was 111.4 per 100.000 men and 192.9 per 100.000 women. Among men the largest group (15%) were aged 70–74 years, and among women 26.9% of fractures occurred at the age of 80–84 years. After the age 75, more women (76.1%) than men (40.8%) had suffered a hip fracture (P<0.001). There were no differences between men and women in the frequencies of left-sided and right-sided fractures as well as in fracture type. Two thirds of subjects (66.3%) were urban residents. No significant differences in hip fracture incidence and average age of fracture were found between urban and rural residents. However, at the age 75 and more, the fracture incidence was higher in urban than in rural residents (685 and 555/100.000, respectively; P<0.001).

Conclusions: In Lithuania in the year 2010, hip fracture incidence was 111.4 per 100.000 men and 192.9 per 100.000 women above the age of 40 years. In the age group of 75 and above, the higher incidence of hip fracture was found in urban than in rural residents.
