Abstract

Background Fractures of a hip are the most serious complication of osteoporosis, causing high rates of mortality, an invalidization, high cost of treatment and rehabilitation.

Objectives To study the mortality due to low-traumatic fractures of the proximal femur in senior age group of Kemerovo town during the observation period: 0-6 months, 7-12 months, 13-24 months after injury.

Methods Mortality is analyzed among 432 patients (328 women and 104 men) aged 50 and older, observed in the trauma departments of Kemerovo town from 01 January 2004 to 31 December 2008. Information about fractures and their outcomes was obtained from medical documentations data of the specialized trauma departments (cases history, maps of drop-out patients from an in-patient department), a telephone survey, data registration of registry offices.

Results In the first 6 months 95 patients died (22,0%) of 432 patients in the period from 7 to 12 months - 42 (12,46%) of 337 patients, between 13 and 24 months from the date of hip fracture - 47 (16,21%) of the 295 patients remained under observation. Found that the mortality in the first 6 months after hip fracture was significantly higher than in the follow-up period 7-12 months (Χ ² = 14,28; p<0.0001), and between 13-24 months (Χ ² = 2,1 p = 0,04). Fatality periods 7-12 months and 13-24 months were not significantly different (Χ ² = 1,04; p = 0.25). In the analysis of mortality by gender the following results were obtained: for 6 months 73 patients died (22,25%) of the 328 women, in the period of 7-12 months - 31 (12,15%) of the 255 female patients, in the period of 13-24 months – 36 female patients (16,07%) of the 224 women remaining under the observation. Noted that the mortality rate in women was significantly higher in the first 6 months after injury than in 7-12 months (Χ ² = 6,3; p <0,001), and after 13-24 months (Χ ² = 2,21; p = 0,04). No significant differences in the comparative analysis of mortality in women in the period of 7-12 months and 13-24 months were found (p = 0,21). Men’s mortality in the studying period of observation was as follows: for the first 6 months 22 men died (21,15%) of 104 patients, in the period of 7-12 months mortality increase was 11 men (13,41%) of 82 patients, in the period of 13-24 months – 11 men (15,49%) of 71 patients. Statistically significant differences in all periods of observation were not found: for 0-6 months and 7-12 months (Χ ² = 1,2; p = 0,17), for 7-12 months and 13-24 months (Χ ² = 0,46 p = 0,7) for 0-6 months and 13-24 months (Χ ² = 0,9; p = 0,3).

Conclusions Thus, these results indicate a significantly higher mortality during the first 6 months after hip fracture among women. No statistically significant differences in mortality among men were found.
